Goulds Booster Pump, SS, 1 HP, 7 GPM

Stepping up the power on Goulds' stainless lineup, the 7GBS10-SS combines a 1 HP motor with a 7 GPM flow rating and an all-stainless multi-stage wet end. It is engineered by Xylem for commercial reverse osmosis applications where higher feed pressure and excellent corrosion resistance both matter, giving system builders the head needed to drive larger membrane arrays and maintain consistent permeate output under continuous load.

This horizontal multi-stage pump runs quietly and free of vibration thanks to its staged impeller design, which builds pressure progressively across each chamber for steady, controlled delivery. Stainless steel construction throughout the wet end resists the corrosive tendencies of many feed waters, helping the pump hold performance over years of continuous duty in demanding water-treatment environments.

Key features

• 1 HP close-coupled NEMA 56J motor, continuous-duty rated
• 7 GPM output with variable, selectable flow capacity
• Stainless steel casing plus 300-series stainless rabbit-lock bowls (no gaskets required)
• Glass-filled composite impellers and diffusers resist corrosion and abrasion
• O-ring casing seal for high-pressure sealing and easy service access
• 1" NPT suction and discharge; alternate part number 10GBS07-SS

Ball bearings inside the motor carry all radial and axial thrust loads, and the mechanical seal can be configured with different face materials and elastomers to match a particular water chemistry. With its centrifugal architecture allowing flow to be tuned within range, the 7GBS10-SS adapts to a variety of commercial RO skids and high-purity water-treatment trains, whether feeding a membrane bank or boosting pressure for downstream polishing stages.

The gasket-free stainless bowls self-align during assembly, simplifying maintenance and rebuilds, while the O-ring casing seal lets technicians open the pump without a struggle. Placing the unit behind effective sediment and carbon pretreatment protects the impellers and seal from abrasive particulate. With regular seal and bearing checks, this Goulds stainless booster pump offers the rugged, low-maintenance reliability installers expect, operating dependably under the around-the-clock loads typical of commercial reverse osmosis service.

The 1" NPT suction and discharge ports allow the 7GBS10-SS to drop into commercial RO skids with standard plumbing, while the extra horsepower over the 3/4 HP model provides headroom for larger arrays or higher-pressure membranes. For operators who need both substantial feed pressure and the durability of an all-stainless wet end, this Goulds pump combines power and corrosion resistance in a continuous-duty package built for the long haul.
