The RWSP Series Self-Priming Pump is a single stage, centrifugal self-priming pump designed for general pumping service from dry, remote locations.  The unit is designed for use above or below fountain pool water level elevation.  The compact design conserves pump room floor space while permitting maximum operating efficiency in a horizontal position.  Applications include small to medium architectural fountain systems.   The RWSP Series is made of 40% glass-filled thermoplastic for extreme heat and corrosion resistance. The unit has a large capacity, single-piece strainer pot for increased strength and quieter operation. It features an easy release, clear lexan cover.  Pump uses stainless steel fasteners throughout. Commercial grade 56 frame motor, continuous duty, energy efficient motor is available in 3-PHASE power ONLY.  Please refer to the cut sheet for technical and hydraulic data as well as pump curves.
