The first question is if the pump can handle hot liquids. If it can't, it is not very suitable in brewing.
It appears the flow capacity is pretty low, at 12 liters / min. That flow rating was probably achieved at a much lower head than the 2.4 meters listed, so the flow that you'll be able to get out of it is going to be less. Its difficult to predict how much less without the pump curves.
Regarding the power supply, I see that they list 5 watts as the output. But, the input power is 24v times 0.4 amps, which is 9.6 watts. If you find a 24v power supply that can deliver roughly double the 9.6 watts of power, that might do for you. I suppose it would also be nice to have a power supply that includes a variable output so that you can throttle the pump. You didn't describe if the pump was a peristaltic or centrifugal type. If its a peristaltic, you have to have the variable output. If its centrifugal, the motor can run wide open at all times and you use a valve on the pump discharge to control flow.
