Goulds Booster Pump, SS, 3/4 HP, 7 GPM

For commercial reverse osmosis systems that demand corrosion resistance from end to end, the Goulds 7GBS07-SS delivers a fully stainless steel wet end matched to a 3/4 HP motor and a 7 GPM output. This horizontal multi-stage booster pump from Xylem is purpose-built to push feed water through RO membranes at the high pressures required for reliable, high-recovery operation, making it a core component in commercial water-treatment skids where dependable feed pressure is essential.

Why stainless steel

The stainless construction stands up to aggressive feed waters and continuous service far better than cast iron, making it a strong choice for treated, mineral-heavy, or otherwise demanding supplies. Multi-stage design provides smooth, quiet, vibration-free pressure delivery by building head progressively across each impeller chamber, while an O-ring casing seal keeps the high-pressure stages tight yet easy to open for routine maintenance and inspection.

• Motor: 3/4 HP close-coupled NEMA 56J
• Flow: 7 GPM, variable capacity within the pump's range
• Wet end: stainless steel (SS) casing and 300-series stainless rabbit-lock bowls
• Impellers and diffusers: corrosion- and abrasion-resistant glass-filled composite
• Connections: 1" NPT suction and discharge
• Duty: ball-bearing motor rated for continuous operation

Glass-filled composite impellers and diffusers shrug off corrosion and abrasion, and the gasket-free stainless bowls self-align for trouble-free assembly during service. Because the centrifugal design allows flow selection across a range, installers can dial the 7GBS07-SS into a specific RO skid, while the mechanical seal can be specified with various face materials and elastomers to suit the application's water chemistry.

Offered in open drip-proof or enclosed motor formats, this Goulds stainless booster pump is a long-lasting pressure source for commercial RO and other high-purity water-treatment processes where metallurgy matters. Positioning the pump downstream of proper sediment and carbon pretreatment shields the wet end from particulate wear, and periodic seal inspection helps preserve both pump life and membrane performance. For facilities that prioritize corrosion resistance and continuous-duty reliability, the 7GBS07-SS is an excellent match.

With its 1" NPT suction and discharge connections, the 7GBS07-SS integrates cleanly into commercial RO plumbing, and the 3/4 HP rating makes it a sensible match for small to mid-sized membrane arrays that do not demand a full horsepower. For facilities running treated or recirculated water where corrosion would quickly degrade cast iron, the stainless wet end pays dividends in longevity and consistent performance over many years of service.
