View Full Version : Chiller Pump Size

Horribly bought an undersized pump for my chiller (294gph at 0 headloss). Its rated as min240gph, should i risk it? after all the headloss I think im closing in on 200gph.

What gph does it call for? It should be ok but the output from the chiller wil be colder. Feel it when its running and have it return to the sump instead of the tank.

Calls for a minimum flow of 240gph and a max of 960gph.

I've calculated my pump will push about 200gph (after headloss).

hmmmmm, that can be tricky. they say it could freeze up if its to slow but its possible it may not. if the pump is new i would return for a bogger one. if not then i would try and use it and test the water coming out. another pump is cheaper than a chiller
