I'm in need of some assistance.
I have an old large, kidney shaped diving pool. I calculated the pool volume to be 24,000 gallons.
I took some pressure/vacuum readings at the pump and calculated 66 feet of head on the pump when at 65 gpm of flow. I have one 1.5-inch suction line and two 1.5-inch return lines. My filter is a Pentair TR60 sand filter with a 60 gpm flow rate with a slide valve.
I do not have a spa or any water features. I have a Barracuda G3 suction side pool cleaner and an Ecomatic salt system.
I currently have a 1HP Pentair WhisperFlo WFE-4 single speed pool pump that is dying, and I want to replace it with a variable speed pump.
I am trying to decide between the 1.5HP Pentair VS 342001 or the 3HP Pentair IntelliFlo 011018. I am leaning towards the VS 342001 since its pump curve at full speed matches the pump curve of the existign WFE-4 pump, and it is $300 cheaper.
Any help would be appreciated.
