Pumping .... (head of water)

Pool Jennings

Hi guys, I have a 3/4hp pump.

I am looking to build some kind of solar heater on the roof of my house.

Can anyone please advise on the maximum head of water that a 3/4hp pump will lift or push ?

I will be using 1/2" or 3/4" inch bore tube if that makes any difference to the answer.

Thanks in advance

Hp doesn't equal flow rate or head. You'll need to look up that information based on that model pump. You have an ag pool so I'm assuming an ag pump which don't self prime so you may need to adjust your system. Most ag solar systems are set at the same level as the pump to reduce overhead

Different 3/4hp pumps have different specs and curves. As Kevin said, you need to get the info off the pump and then look up the specs.
