Hey, everybody, I asked Walter to start posting here so we could get pump questions answered right from the source!  Walter, thanks so much for joining us!  I have a question....my pump has 2 small openings for oil on it.   How often should I oil it and what type of oil do you recommend?
Title: Re: Questions you may have about March Pumps? post them here
Post by: walteratmarchpump on February 27, 2012, 05:04:39 PM
Good question. Depending on the motor that comes with the pump it may or may net need oiling. If you look on the motor itself, on the white label that has all the specs of the motor like voltage etc....you will find it say "OIL" with arrows on each side pointing tot he end caps of the motor. At the edge of the caps you will find a hole and if you look inside the motor you will see a small channel leading tot he center cap where the sleeve bearing is located. Any 3-in-1 oil will work fine. You can pick it up at any hardware store. Its most commonly used for sewing machines and small motors etc. Or any light weight machine oil you can find will work too. As for how often to oil these units? That depends on how often you use it...what kind of environment you keep the pump in etc. For most beer brewers that keep their equipment in the garage and has for the most part a constant temp...then once a year is more then enough.
If your garage is detached and you get big temp swings like up here in the winter or if you are in a dry/dusty region then 2-3 times a year may be warranted. And it only needs like 2-3 drops per bearing.

If your pump motor does NOT have that "OIL" marking on the motor label then you have a ball bearing motor and it does not require any lubrication.

Thanks, Walter.  My pump does have the oil markings and I'm in the detached garage/temp swings/dusty category.  I've had it a couple years and never oiled it, so I guess it's time!

Hey, great! Walter, why is there an availability difference between March USA and, for example, March May in the UK? There's a really nice nano pump at morebeer (http://morebeer.com/view_product/12009/103556/March_Nano_Brewery_Pump_-_Stainless_110V) but the march may guy told me he didn't carry anything like that. Do you sell a 220/50hz version?

The motor Mfg actually tells us that theres enough in the bearing area right out of the factory that in a 24/7 use it will go 3-5 years no problem...but in those cases its sitting in an indoor situation and the temps do change much. :)

The March May guys are a sister company and they buy a bunch of our pump heads but install their own motors for the european side of things...they even have alot of their own pumps that we do not sell here.
That pump you posted the link to is something we made to try and get a stainless pump to the larger beer guys a bit cheaper then the standard industrial type we normally sell. If you call them up again try and ask for the TE-5S-MD or their equivalant. If they have our version then the motor is TEFC and is 115/230v 50/60hz compatible. Or they will have one just like it. And see if you can get a price break if they change out the full stainless impeller with one made out of Polysulfone or if not then Kynar should work as well.

I wonder if I could use my 809 to pump a mash, like in a decoction? I'm afraid to try it because I don't think it will work.

It will depend on how much is going through the pump at any given point during the pumping. The pumps actually can pass solids up to about 1/4" in size....problem is if they happen to pass through just right and jam between the impeller and the pump housing then it will stop the impeller and decouple the mag drive. The the motor will freewheel and you would get any pumping action out of it. I know the mash is a soft solid and in small quantities it will pass through the pump...if it clumps up or you get a bigger pocket of mash going through you will have problems....all i can suggest you try is possibly after a brew session when you are done with the mash.....dump it into a kettle of water and try pumping it through the pump and see how it goes. You will probably find you need to keep stirring it so its evenly suspended in the liquid as its getting pumped out. At least this way if it does clog your not ruining a good brew. :)

Walter - Thanks for the detailed response. It's great to have you here to answer questions.

Do you think the AC-5 could handle something like that better? I was looking at the drawings, and it looks like the impeller is a different shape (4 blades instead of 6) so maybe that could handle bigger chunks?

I'll try the experiment you suggested next time I brew.

The AC-5 will handle more/bigger "stuff" but again if you get that big clump of junk going through the pump then it too will get chocked up and stall on you. the only pumps that would be able to pass debis along would be a shaft drive centrifical...butt hen you have the shaft seal to worry about. Theres also a gear drive pump but again you have a shaft seal and then the gears will crush the debris and make it smaller/finer. And you could also use a peristaltic pump but they dont realy move a great deal of liquid around...i'm sure you could make a DIY peristaltic to move a good amoutn of liquid of you used like a 3/4-1" line butt hen you would need a decent size motor to do it with.  :)

Thanks for joining us Walter!

Also want to thank Denny for asking Walter to join us here.

Anyway...I have a question regarding my March pumps. I have a Brutus 10 clone single tier brewstand. I use two pumps that are mounted below the kettles, and from time to time I have a problem priming the pumps. What are your thoughts in this regard. Any ideas, suggestions or input would be very much appreciated.

Thanks!

I have a 809 HS pump.  What does the high flow impeller do for the performance of that pump?  I seem to recall the shut-off head of that HS model is on the order of 12 feet.  Is there a pump curve for that impellor?  What is different about the impeller and when should a brewer consider its use?

Thanks!

If you have the 809-HS inline version then right now it will do 6gpm and a max of 12.1 feet.
upgrading to the 815 inpeller will increase the max gpm to 7 and raise the head to 18 feet
it also helps a bit more in keeping the prime and passing bubbles easier due to  the impeller being larger and taking up more space. The standard inpeller has a dia. of 1.687" and the 815 is 2.156 and has a stronger magnet.

Walter,

Thanks for this great info.  I just ordered a new impeller last week as I was having trouble pushing wort through my heat exchanger and back into my mash tun, and a little trouble with priming and air leakage.  I am hopeful that this upgrade along with a few hoseclamps will solve it.  However, if not, are there other pumps availible (or on the drawing board) between your 815 and the nano pump (325?) at $350?

The pump on the right side with the plumbing attached in the pic.....take the 4 phillips screws out and rotate the pump head 180* so the inlet is at the bottom like the one on the left.....you are trapping air in the top portion of the pump head and cavitating it. Check out the posting i made about pump head orientation and look at pic#4 it will show you how you get air trapped in the top of the pump head with it mounted like that. Other then that it looks good......only other thing i can suggest is if you happen to be trying to pump the liquid at boiling temps then you may be drawing air in off the bottom of the kettle as the bubble form and you could cavitate the pump that way too.....just cut the flame and wait like 30seconds for it to calm down and then crank the pump up.

Exactly how I have mine and I never have any issues(except the mentioned boiling liquid).  And I have the same system just with converted keggles instead of blichmann, so I can personally attest to that!

How do we go about ordering parts for March pumps?

We dont sell direct so the only way to get parts would be through a distributor. You can find a list of them on our website under the distributors tab. We have them listed by state so find the ones near you and give a few of them calls to see who can get you the best price.

Rebel Brewer has the impeller for the 815 for $22 plus shipping. I just installed it, but haven't used it.  The old one is tiny by comparison. The new one fills up the housing nearly.

I'm so sorry that i overlooked your posting...to answer your question the pump in-between those two you mention would be our AC-3B-MD. That pump will give you an output of 10gpm and can pump up to 20' of head height. Its made out of the same material as the 809 and can handle the same temps..... :)

A good start would be to look over the tutorial i posted a few threads down or just go here: http://www.homebrewersassociation.org/forum/index.php?topic=11157.0

Once you understand the mounting issues of the pump head the next thing to check out would be the plumbing itself. Try and keep the hoses or pipes as short as possible and try not to have any high spots between the pump and the supply tank its drawing from. If you happen to trap some air in the line before you start the pump, even though it may be primed in the begining, it will suck that air pocket in and cavitate and give you problems. Most times people that have problems on start-up will shut the pump down and start again and most times that was enough to purge all the air out of the system. That usually tells me the pump head is positioned wrong. Another issue with priming the pump is when you have a full rolling boil.....in that case you are sucking air being generated from the boiling right off the bottom of the pot. In those cases just kill the flame and let the brew settle down for like 30seconds before starting up the pump so its not generating bubbles anymore.

I am in the process of upgrading my system and implementing a pump. I currently plan to use it only for recirculating wort back into the kettle while my immersion chiller is chilling the wort. I have a rather tall brewstand and use gravity for taking the hot liquor to the mashtun and running off wort from the mashtun to the kettle.

I see there are polysulfone headed pumps and brass/bronze headed.
I've also been made aware the polysulfone are prone to wear and have fragile threads.
I don't want metallic taste in my beer from the brass. Is this an issue?

Please help me decide which way to go. Pros and cons of both types?
I tend not to want any brass in contact with my wort if I can help it but frankly I've not been able to detect any detracting flavors when using brass ball valves or brass barb fittings on my cooler mashtun or elsewhere in the system to this point.

TIA

People have had issues with the plastic head pumps with breaking off the threads.....but we find its more that they are over tightening the fittings when installing them on the pump. We usually recommend 1-2 wraps of Teflon tape....then hand tighten the fitting on but don’t try and crank it down as much as possible by hand.....then when you get it hand tight, give it another 1/4-1/2 turn with a wrench and that should be more then enough. The threads are tapered so the more you tighten it, the more stress you put on the connection as it gets tighter.
As for Brass or plastic....I cant really give you an answer on which is better or not. I can just give you information and you have to make a decision for yourself.
If you go with the brass, the advantages would be the strength most of all....they can take  more pressure internally and obviously have stronger threads for fitting connections. But the biggest thing that i just want to make you aware of is that the brass contains up to 6% lead content. Keep in mind that’s the very same thing you have in your home fixtures unless you live in CA where they mandated 0% content few years back. The only difference is that no one drinks the hot water coming out of your home faucet, and the temp really never see above 135* out of you faucet either. So as to what affect that will have on anything i really don’t know.  If you wanted a metal pump head, you could go with a stainless version we have. But i know for most people its too expensive and there is a competitor that sells them for way cheaper then us. I have seen them sell a complete pump head for almost as much as we buy just the raw castings for!! And we still need to spend some time machining the parts to our tolerances before final assembly!  We strive to try and keep as much as possible made in the US before going elsewhere for parts. Those stainless pump heads are coming out of a foundry in PA. The competition is China...that's why they can sell them for so cheap. If you happen to have an existing 809-HS pump then you could go and buy their stainless pump head and swap it out and have stainless that way....just an option to throw out there for you guys.. :)

Walter, I use an MDXT-3 pump that I bought 10 years ago from McMaster-Carr.  The manual shows the maximum liquid temperature to be 190ºF, however, I regularly pump 200+ water through it.  Other than the occassional air lock, what other negative effects should I expect to crop up?

That pump is rated for 190*F....and many people do use it for brewing because they use it for short runs at those hot temps. The concern we have with running it above the 190*F  temps, would be more for the long term applications. You may see a softening of the plastic if you were to immedietly take the pump apart and inspect it. And as  long as theres no pressure going throught he pump you will probably never have any issues with it. The polypro we use, shows temps ok to 220*F but the issue we have is that with the design of the pump, the back end of the impeller/housing runs hotter due to low fluid turn over during operation. If you take the pump apart occasionaly, just inspect the rear housing for any deformation and same with the imeller...if all looks good then no worry's :)

During my upgrade to the 815 impeller, I noticed that the teflon washer was long gone.  Unfortunately, I only ordered 1 new teflon washer with the impeller. 

That 809 HS pump is over 10 years old with about 100 batches.  I'm sure the washer was probably gone a while ago, but no ill-effects were noted.  How important is that washer and how long (run-time hours) do those washers last?

The cost of the washers is next to nothing, so the only real cost is the shipping.  Wish I had ordered a couple of spares.

Thanks for the reply.
For now I've elected to pickle the bronze pump head using a mixture of vinegar and hydrogen peroxide. I found instructions on this process on John Palmer's how to brew website. It was like high school chemistry all over again! I'm much less concerned about any lead making it's way into my brew than before.

The stainless heads are sold out all over the web but I eventually plan that as an upgrade anyway.

Thanks again

Sorry guys, i wasnt getting notifications for some reason...anyway getting back on track:
 Most guys are now ordering the 815-PL....or upgrading their 809-HS pumps with the 815 impeller.
The thing i'm not sure about, is how much pressure or restriction that chiller plate would put ont he pump. Once thats figured out then i could size the pump easily.

The washers will normally last the life of the pump as long as theres nothing attacking them chmically...or unless you have restriction on the inlet side of the pump sucking the impeller up against it...The newer washers are all white...the older ones were black and sometimes hard to see if they were still there or not....it may be the washer was there but didnt look like it! :D

Walter, I dropped my 809 off the utility table, It makes a humming sound but that is all. I thought I would ask before taking it to a pump repairman. Any ideas what I could do to fix it?

First thing i would do is remove the pump head off the motor bracket (4 philips screws) and run the motor alone. If it works then the motor bracket shifted slightly and what you need to do is install the pump back on. Plumb it up with water...then just barely loosen the 4 flat head screws holding the bracket tot he motor and tap it around the base till you get the bracket re-aligned again and not rubbing....you'll know when you are close when it starts pumpng again...it will most likely have a metal rubbing sound to it as the drive magnet rubs against the stainless rear cover plate...just make small taps till its quiet again and tighten it all up.
If the motor wont go at all then all i can say is send it back to me here and i can try and hammer it back out for you....i have a good streek in fixing these guys as of late! :D

Thanks for the reply.
For now I've elected to pickle the bronze pump head using a mixture of vinegar and hydrogen peroxide. I found instructions on this process on John Palmer's how to brew website. It was like high school chemistry all over again! I'm much less concerned about any lead making it's way into my brew than before.

The stainless heads are sold out all over the web but I eventually plan that as an upgrade anyway.

Thanks again

No problem...let everyone know how the pickling works out for you incase anyone else is thinking about going brass as well :)

thanks for sticking this thread at the top. I don't get a chance to frequent here as often as I would like. Seeing this thread just solved an agonizing problem as I had my pump head mounted upside down. Who'd a thunk??  As time passes, I know there will be numerous new brewers buying pumps and trying to use them for the first time. This thread should save them from "pump anxiety" ... thanks again Denny for have Walter's much needed info posted here.

Walter,

I have an 809 High Flow that I got through more beer about a year ago now. A couple months ago it stopped working. I took the head apart, cleaned everything out and put it back together, oiled the bearings and did a quick check to see if it worked, motor turned on and the impeller turned. I thought that was the end of it. Tried to pump some water and the motor turned, I got an initial surge, but then nothing would pump through.  I took the head apart again and found that the impeller was sticking on end of the shaft took some 1200 grit sand paper to the shaft and polished it a little, impeller now turns freely on any part of the shaft. Turned on the pump, same thing, initial surge and then nothing. The pump is definitely primed, it seems to be decoupling from the impeller somehow. What should I look for to try and replace? Bad magnet?

Any help would be appreciative.

Cheers,
Rich

I would like to mount my pump to my brew stand using u-bolts.  Looks like I need to use 1/4" diameter, and ~2.25" to 2.5" for the width.  Problem is, the largest width u-bolt I can find at 1/4" is 2".  Any ideas on how to mount the pump without welding?  Is it reasonable for me to drill out the holes in the mounting bracket to get to 5/16"?  U-bolts with 5/16" diameters come in larger widths, which is why I ask.

I'm using this diagram to figure out the needed dimensions.  U-bolt would be going from front to back (right hand side of diagram).

Don't use U-bolts.  I use large hose clamps and wooden saddles (matching the diameters at the attachment points) that encircle the motor can and pump magnet housing.  You do not want to put too much pressure (especially if its uneven) on the motor can or you will deform it.  This mounting has worked for over 10 years.

Thanks for the tip, Martin.  Do you have a pic to help show?  I wasn't planning on putting the u-bolts over the housing.  I had planned on putting them through holes in the mounting bracket with the pump and bracket sitting on top the stainless steel tube frame.  I have the pumps attached to the stand this way right now using some zip ties just so I can make progress on getting all my hoses measured and cut.

Clever idea!
I have some 1/2" UHMW plastic I could use for saddles too. Then there's a need to shield the motor from fluids. Brewstand upgrades never die, they just grow new ones.

Hey Walter -

Thanks much for chiming in and helping everyone with your pumps.  I converted to a full gravity system a few years back, and sold my home made brutus that had two pumps.  It all worked great.  I just got tired of all the hose and pump cleaning. 
Title: Re: Questions you may have about March Pumps? post them here
Post by: maltdaddy on May 08, 2012, 02:40:43 AM
Thanks for the posts guys.  I bought a 5/16" high speed drill bit, and the holes opened up super easy.  I should have went with the 3/8" bit, as I kind of had to move the bit around to widen it more than 5/16 (the u-bolt threads were 5/16" and the fit was too tight at first).  Pumps are secured and water test went smooth. 

The only other issue I had was Lowes didn't have the size u-bolt I wanted.  It was too long, so I had to put the loop end of the u-bolt facing upwards under the pump body.  The u-bolt is 2" wide (the next size up is 2/5", which is too wide), so the loop doesn't fit right against the mounting bracket.  Not a big deal, but doesn't look as nice.  I can post a pic if people are interested.

I've noticed the -C models of the March pump have a center inlet ( http://www.marchpump.com/site/files/966/112279/382929/612764/0809-0053-1100_R3.pdf ). Is there an application for these for homebrewers? Who uses these?

Second q: Assuming I get the 815-PL, I assume I go with polysulfone QDs/couplers (versus other plastic)?  I'm considering a March pump to move water from the HLT to the mash tun, from the mash tun to the brew kettle, and from the brew kettle into the fermenter with a plate chiller inline, with an option to prechill the water with an IC I'm not using and a submersible pump.  I'm trying to go as "lift-less" as possible. Given my current brew setup in an apartment (moving things among kitchen, deck, and lower level), I am thinking of mounting this pump to something totable or installing in a toolbox, and there will be a lot of connecting/disconnecting during the brewing process, some at high temp.

3. In terms of a basic pump startup list, does this seem right?

Pump
Something to mount pump on (or in) + hardware
1/2in SS ball valve to manage flow from output
1/2in quick disconnects (4, two male, two female)
Thermoplastic tubing
Hose clamps (to ball valve barbs on BK and cooler)
Inline GFCI

Plus I may upgrade the 3/8in brass ball valve on my cooler with a 1/2in SS, and either create a strainer similar to the one I made for my cooler with a plumbing supply line (except with a SS t-valve and a SS QD) or buy a ready-made strainer.

I've seen pumps mounted in tool boxes, its feasible.  I've also see someone selling a mounting plate that is bolted between the motor and the pump housing.  That allows the unit to be bolted to a base.  In the case of a tool box, you could mount the pump in the same way as with that mounting plate in that you could put the motor inside the box and sandwich the tool box side between the motor and pump housing. 

I don't really like the QD units since there are vanes inside those couplers that can clog.  I like the stainless steel camlocks with silicone gasket.  I have the camlocks with barb fittings.  The only bad thing with those things is the ID through the barb ends is kind of small.  I've found that it doesn't really matter though, the flow rate is only slightly affected.  I calculated a couple of feet of head loss due to the barb ID, so its not really a big deal.

Brewing is not worth dying for, so the GFCI is an important consideration.  Its good you're including one.  Including valves on both sides of the pump is good so that you can keep fluid in the pump.  Of course, you only throttle the pump on the output side. 

Although the center inlet configuration pump is more efficient, I like having the inlet and outlet pipes in line so that those pipes can be more easily supported.  I have my pump mounted in a frame with plywood plates at each end with precisely drilled holes that support those pipes and valves and prevent the breaking of that fragile plastic pump housing.  I've had my pump for almost a decade now, without breaking the housing.  I suppose that mounting the entire pump within a tool box would make it possible to pass the pipes through the sides of the box to support the pipes.  I guess if you had one of those pump mounts, you could bolt it to the box bottom and pass the pipes through the walls. 

Enjoy!

Thanks -- lots of good info here. The pump-in-a-toolbox projects I've seen are similar to this (based on a 2009 BYO article):

http://snakeriverbrewers.org/index.php?topic=3972.0

I like this one because he wired the GFCI into the toolbox in a way that it could be used independently of the pump. What my dad the electrician would probably suggest if he were still on this planet is that the power switchplate should be labeled to differentiate main power from the pump, to prevent accidentally switching on the pump while dry.

Edit: just to be clear, you're using stainless steel camlocks with plastic threads? No wear issues?

Update: as I close out my homebrewing upgrade projects for a while (work kicks up in two weeks and doesn't stop until next summer), I'm glad I didn't get the toolbox before the pump arrived. It's just heavy enough that I see I don't want to do that. The pump on a small footstool idea might work (and is a project I might even be able to sneak in). For right now I just put the pump ON a small footstool. But it's great to have a pump!

There was a previous question about using the March 815 size impellers in the 809HS pumps, and I just did that change this past week. It did make a difference in the speed and ease pf priming and my pumps are already in the optimum position. They both now prime quickly and pump at an increased volume (not that a volume increase was the need).

What I also found is that when I added a new pump head recently (stainless) that the head I removed already had the high flow impeller installed. I thought it was just a coincidence that when I installed the new head and repositioned my pumps on the rack that it seemed like they were harder to prime than before. It was the impeller, and the reason that I'd use this one pump more than the other regularly is that it always seemed to prime easier. Now I know why :-)

I have an 809 that I bought from someone retiring.  It has always run well for me.  This past weekend I had some issues with air locks causing free wheeling.  Whenever this occurred I would immediately shut the pump off.  I then would find it would not restart and I would notice the fan would pulse when the switch was turned on, but it would not turn.  The fan was magnetically held in place.  After a few minutes (potentially as the motor cooled) it would run.

Is there a potential dead spot in the motor windings or could it be overheating?

I had a similar issue with mine.  I took the head off and found that the impeller body had expanded and was binding inside the head.  Maybe time for the 815 impeller upgrade?

I am trying to determine my need for a pump with my set up. I currently brew 5 gallon batches and use a 10 g HLT, 10 g cooler mash tun, and a 15 g kettle to brew. I'm considering a pump for moving water from my HLT to my cooler. Right now, I have to pick up the 5+ gallons of 150 degree + mash water and dump it into my cooler, and I know it's only a matter of time before I dump this on myself in some capacity. My question is this: Are there effective alternatives to investing in a pump? I don't have the materials to use a gravity fed system to simply drain it down. Any suggestions regarding alternatives or additional info on pumps would be greatly appreciated! Happy brewing!

Gravity setup would be quite tall and require a ladder. Pump is nice  but you'll soon discover you want fittings and hoses and clamps. The only other techniques I've heard of involve using pulleys or block and tackle to raise containers full of hot liquor or mash.
Still seems dangerous to me. Personally I like my pump and my setup and don't plan to go back to a gravity setup.

I have a stainless mash tun. So my mash water starts in the tun. But I heat sparge water in an hlt. I don't notice much temp loss caused by the pitcher  when I transfer that. Its usually 170° when I start and ends up about 160-165 for mash out.

Hi guys, sorry i haven't been on here in a while...not sure why but i don't get notices when there are new postings on the thread...i figured there was no traffic here...
anyway yes you can buy just the stainless head if you like. The part numbers are:
0809-0150-0000 for the center inlet style
and 0809-0211-0000 for the inline version.
you can order one from any of our distributors.
You will also need a different o-ring if you change over as they are different size. that's part# 0809-0165-1000
As for the impeller...that depends on how much debris goes through the pump and how hard/soft it is. Most very soft stuff will get shredded in small amounts and pass right through....other will jam the impeller and decouple the magnets and you will loose all pumping action.

We would have to see the motor and test it....but from what you said in the posting i would venture to guess the clearance on the impeller ID is too tight and its sticking on the shaft when it heats up. it could be tight from the molding process or you may have sugar buildup from not cleaning it out good enough.....easiest thing you can do is drill the impeller center section out with a 17/64" drill bit to give it more clearance.

I have a March Pump 809 HS and I recently started brewing with an Edelmetall 30 gallon kettle. The problem is I don't feel as though I get enough flow from the pump to effectively create a whirlpool using the kettle's built in tangential port. I have tried several experiments to improve the situation (heights of the pump, ensure hoses are short and 5/8", and even a friends chugger pump) but nothing seems to move enough water/wort to really achieve an effective whirlpool.  Any suggestions on options for improving the flow are greatly appreciated!
Title: Questions you may have about March Pumps? post them here
Post by: Stevie on February 17, 2017, 06:36:17 PM
What type of fittings are you using? The most important leg in the plumbing is the input, you need to make sure the wort has the best possible path to the pump head.

30 gallons is a large volume. Might need a second pump in series to boost the output pressure.
Title: Re: Questions you may have about March Pumps? post them here
Post by: rtemplen on February 17, 2017, 06:41:48 PM
I believe all fittings on the kettle and pump are 5/8" stainless steel barbs.
I am interested in understanding how another pump in series would benefit this situation? Is there a bigger single pump that would improve the situation? Any modifications to the existing pump/head that could be made? Does anyone else have this kettle and have a setup working well for them?

Thank you again for the help!

Are you using disconnects? If so, what type? Links? Is there a leak causing cavitation?

Are you expecting a huge vortex when you should be expecting a decent stir? Is the wort moving at all?
Title: Re: Questions you may have about March Pumps? post them here
Post by: rtemplen on February 17, 2017, 06:52:14 PM
I am not using disconnects. The 5/8" short length silicone hosing is simply slipped over the 5/8" barbs and held in place with hose clamps tightly. No visible movement is seen on the top of the wort unless a leaf (or something similar) is placed on top of the liquid and then it would take ~8-10s to travel the circumference of the kettle back to its starting position. I would like a vortex to be enough to generate the purpose of a whirlpool, which is to drop material in the work into a cone in the bottom center of the kettle. Currently the 809 HS and this 30 gallon kettle combination do not provide this whirlpool effect.
Title: Re: Questions you may have about March Pumps? post them here
Post by: Stevie on February 17, 2017, 07:05:50 PM
It might just be too much pressure for the pump. Try in series with your buddies chugger. Out of march plumbed to the in of the chugger.

Is there a way to restrict the out flow inside the kettle?


Larger pumps do exist, but carry a premium price.

I have a 16 gallon kettle and get a solid whirlpool of going without fail.

Email March or Northern Brewer to see what the recommend.

I asked in the store last weekend at Midwest Supplies (same company as Northern Brewer) when picking up yeast for the Surly AHA wort release. 5 or 6 of their staff was stumped with this problem and stated they do not sell a larger pump. They started googling on their phones to now avail, hence while I am giving this forum a try for my first time. I am not sure what you are referring to be restricting flow inside the kettle. There is a ball valve on the outlet port of the kettle (like most kettles) and a ball valve on the input port (tangential port), also on the outlet side of my pump I have a ball valve, these are all wide open and 1/2" or 5/8" if I recall.

Any additional advice is welcome. Thank you!

I mean the port on the inside. Like putting your thumb over a hose creates a smaller higher pressure stream. Maybe the stream is too large with little oomph behind it.

MoreBeer sells a large pump and I know March makes pumps that cover many brewery volumes.

First thing i would do is change your outlet line to 1/2" ID....the output of our pumps are spec'd according to that line size.....so going bigger may help in less friction but keep i mind you then have to fight against the weight of the fluid in the line at the same time. So going smaller in your case may help keep the velocity of the fluid up and help start the whirlpool faster. Another option would be to upgrade your impeller to the 815 model. The 809-HS pumps and the 815 pumps are virtually the same other then the impellers inside them. so that impeller change would be able to boost the output head height from 12' up to about 18' so it in essence would gain you an extra 2.6psi over what you can make right now.
Any other questions feel free to email me at work wwojcik at marchpump dot com :D (i spelled it so the email harvesters would get it :D )

I usually reply to emails the same day unless its over the weekend...so if you didnt get a reply from me by now then i must have not got it....did you send it to my email or to one off the website? If it went to sales then it may not have been directed back to me....

Uncovered an issue with my pump the last two brew days.  I have a chugger SS head pump (hope this threads ok, not a march pump?).  The pump has worked great for 5+ years but the last two runs it will periodically stop pumping fluid though I still hear the motor running.  It seems to go to a higher pitch when this happens.  I turn it off, give it a few minutes rest, and it works again- for awhile, until the same process happens again.  I have an electric single tier setup and continuously recirc thru the entire mash with a heat exchanger in the HLT.  I did do a hop stand at 190 x 30min the first brew day it malfunctioned.  Could cycling the extra high temps for so long have damaged it?  Figure it’s time to take it apart and see what’s potentially going on inside.

Hard to diagnose without seeing it first hand....but i would guess you have a sugar buildup inside the bore of the impeller and when it heats up it chokes out the liquid and seizes on the shaft enough to de-couple the magnets. Take it apart and clean the impeller really good....you can also drill out the bore of the impeller with a 17/64" drill bit to let more liquid in between the impeller and the shaft for better lubrication.

Walter, my pump is working great but the thrust washer has been lost.  I've been running it without since the shipping for a washer is significantly more than the part itself.  Are there any options other than ordering one from you?

Sure...go to the hardware store and find yourself a stainless washer with a 1/4" ID hole and the smallest OD you can find so it doesn't block the inlet hole inside the pump and you should be good to go. I'd bring the pump head with the shaft installed with you so you can trial fit the washers onsite
