I am trying to find information and flow curves for my pump. It is one of Hayward / PowerFlo Matrix / SwimPro Voyager, all these names are on the box, manual or nameplate, 2HP 2 speed, model SW159412STL. I went on the Hayward site and can't find the SW1594 model anywhere or much reference to a 2 hp pump. Maybe it's a special model that is supplied to the pool dealer as a package deal with pump/filter etc. Regardless, I still want to get the pump curves for flow vs head or pressure. Over the winter I want to design a solar heater system, and wanted to get an idea of the flows for the low & high speed settings. I do have the manual that came with the pump, but it is very lacking with technical information. I wrote to Hayward Customer Service a week ago and haven't heard back.
Here is my nameplate:
