Hayward Power-Flo Matrix Low Speed Flow Rate

[DonW]

I am considering a new pump and was looking for data on the flow rate for a Hayward Power-Flo Matrix 1.5HP Dual-Speed SP15932S, specifically the low speed. For the life of me that information is not out on the web. Can someone provide GPM on the low speed?

Low speed will have exactly half of the GPM of high speed. What the actual number is very much depends on your plumbing, how long, what kind of filter, how many bends, what kind of pipe/hose, etc.

Great. Thanks Jason!

You could ask Hayward through their site. I asked them the same question about my pump which is 1hp 2 speed and they told me on low 20-30 gpm with 20ft of head. The 1hp matrix is said to have 86gpm at 10- 20ft of head.
As Jason said there is other things that come into play also. I guess the only sure way is to have a flowmeter hooked up.
