I have a Century Lasar 2 speed motor, branded Hayward, purchased from Watsons with a SwimPro (cc1750) cartridge filter. I need help identifying what I really have. The motor label shows SP1520Z24ESC, part no 7-193824-01, 115V, HP 2. -2.5 SPL, 15.0/4.4 Amps. The model # on the pump housing is SW159412STL. I'm trying to figure out the true horsepower, the flow rate on H/L, and a suitable replacement so I can determine what heat pumps will work with what I have. The closest models I've been able to find is an ao smith BN51 (230V) or an uprated SP1593TL (1.5 HP 115V). Anyone have any experience with this private label motor? Thanks!

Any 2 HP pump should give sufficient flow for a heat pump. I am not sure what you are trying to figure out.

I think I identified an equivalent motor using a kill a watt and a lot of searching. While it has a 2HP faceplate rating it appears the equivalent is a Century BN50V1 1.5HP 3450/1725 115 or a PowerFlo Matrix 1.5 HP. What I'm trying to determine is if this motor on low speed will supply enough GPM for a 110-130 BTU heat pump. The manual says 80 - 91 GPM with 10 - 30 Ft of head - I assume on high speed. I can't find any data on what it will pump on low speed which is about .25 to .33 HP. Appreciate the help.
