Questions you may have about March Pumps? post them here

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?

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!

Here's my system.

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.

Thanks a lot Walter. I will make the recommended adjustments. It makes good sense.
