Product Description:
The RainFlo MHP50 is a 115V/60Hz 2-stage 1/2 HP centrifugal surface pump with all stainless steel 304 construction in the water end. Its solid construction and thick casings result in extraordinarily quiet and reliable operation.
The MHP50 is typically paired with an auxiliary pump control for on/off functions and run-dry protection such as the
RainFlo 115V Pump Controller.
