Pump, Cent, Cast Hi Pres Bstr, 1 HP 7GPM

When a commercial RO system needs reliable feed pressure at moderate flow, the Sta-Rite Cast Iron High-Pressure Booster Pump (1 HP, 7 GPM) is a proven workhorse. This multi-stage centrifugal pump pairs durable cast iron construction with the steady, elevated pressure that reverse osmosis membranes depend on, all at a 7 gallon-per-minute flow rate well suited to small and mid-sized commercial systems.

Pressure that membranes can count on

Reverse osmosis depends on consistent feed pressure to drive water through the semipermeable membrane and maintain proper recovery and dissolved-solids rejection. A multi-stage centrifugal design builds that pressure efficiently across multiple impeller stages rather than relying on a single high-speed impeller, and cast iron construction stands up to the continuous operation common in commercial treatment environments where pumps run for long stretches.

• Sta-Rite cast iron multi-stage high-pressure booster pump
• 1 HP motor delivering 7 GPM flow
• Multi-stage centrifugal design for high discharge pressure
• Built to provide steady RO membrane feed pressure
• Durable cast iron body for demanding duty cycles
• Suited to small and mid-sized commercial RO systems

Install this booster pump on the feed line ahead of the RO membranes, sizing it to the system's required pressure and flow for optimal recovery and rejection. Adequate pretreatment upstream, including sediment filtration and chlorine removal, protects both the membranes and the pump from fouling and damage, while correct electrical and plumbing connections ensure safe, efficient long-term operation. For commercial water treatment builders who need dependable feed pressure in a rugged, time-tested package, this Sta-Rite cast iron booster offers steady performance and a long service life, making it a sound choice for the heart of a commercial RO build.

For service companies and system builders, this Sta-Rite booster offers a well-proven combination of cast iron durability and dependable multi-stage pressure at a flow rate that fits many common commercial RO sizes. Properly applied and maintained, it provides the steady feed pressure that keeps reverse osmosis membranes producing quality permeate reliably. With its cast iron durability and dependable multi-stage output, it remains a trusted feed pump choice for small and mid-sized commercial reverse osmosis builds across many applications.
