March Pump For HERMS

[owentp]

So I have a 6 gpm pump. Is that too fast for my homebrewing HERMS that I want to create? I have been reading and researching and seeing a lot of 3 gpm pumps.

You can always throttle the flow with a valve on the output side of the pump. That is an advantage of a mag drive pump.

Def go for the higher flow pump. You can always add a ball valve at the pump OUTLET (not the inlet, and that may result in cavitation and loss of prime), to restrict the flow to the level you desire.

[Edit] damn, Kurt beat me to it!

Or depending on how you set things up you can always put a smaller fitting on the outlet with like a 1/4" hose to choke things down with too..
