Pump, Cent, Cast Hi Pr Bstr 1.5 HP 10GPM

Boosting feed pressure for reverse osmosis and other demanding water applications calls for a pump built to run hard, and the Sta-Rite Multi-Stage High-Pressure Booster Pump (1-1/2 HP, 10 GPM) delivers exactly that. This 14-stage cast iron pump produces strong, steady pressure at 10 gallons per minute and runs on 115/230V single-phase power, making it a versatile choice for commercial RO feed duty and general pressure boosting where reliable high pressure is essential.

Engineered for continuous duty

At the heart of this pump is the SignaSeal floating impeller design, which minimizes thrust loads so the unit can run continuously without damaging the motor bearings, mechanical seal, or pump hydraulic components. That thrust-tolerant architecture is a key reason multi-stage pumps of this type achieve long service lives in applications that keep them working for hours on end, day after day.

This pump is commonly installed ahead of commercial reverse osmosis membranes to provide the elevated feed pressure they require for proper recovery and dissolved-solids rejection. Size the pump to your system's required pressure and flow, ensure correct electrical connections for your supply voltage, and protect both the pump and the membranes with adequate upstream pretreatment to keep sediment and scale at bay. Robust cast iron construction and the thrust-tolerant impeller stack let this Sta-Rite booster handle the rigors of constant operation, making it a dependable, long-lived pressure source for commercial water treatment systems and other high-pressure boosting needs.

For system integrators and service companies, the combination of single-phase flexibility, high multi-stage pressure, and proven continuous-duty design makes this Sta-Rite booster a versatile pick across a range of commercial RO and pressure-boosting projects. Properly sized and maintained, it delivers the steady, high pressure that demanding water treatment applications rely on day after day. With its rugged cast iron build and field-proven SignaSeal impeller design, it gives commercial installers a dependable, long-lived feed pump they can specify with confidence.
