one and a half horsepower.
I have a 28,000 gallon pool and my pump is 1hp. Works fine.
You should never run a swimming-pool pump dry! The most likely problem, from the rather flimsy evidence in your question hinting at it not rotating, is not with the pump or its motor but a fault in the electrical supply to the pool plant, or in the timer or other pump controller.
The purpose of a swimming pool heat pump is to rise the temperature of the water. The pool then can be used for swimming even on days when the weather is not perfect. The swimming pool season is extended.
It is a great pump. It isn't only quiet but it also produces the highest water flow offered by any pump.
1/2 horse power
Because the pump is set to "vacuum to waste".
Alegria is a good reseller if you want to buy a heat pump for your swimming pool (in Belgium).
Between a 500-gallon-per-minute pump and a 2,000-gallon-per-minute pump.
A 1 HP SHOULD DO FINE, But if you've GOT SOLAR, a 1.5 HP.
the best pump is a sta-rite dura glas .. a 1hp is what i would use
Pump the water out or put a cover over the pool.
Then you can't swim
