Goulds Booster Pump, SS, 1.5 HP, 10 GPM

For commercial reverse-osmosis systems that demand maximum corrosion resistance, the Goulds 10GBS15-SS delivers a fully stainless steel, horizontal multi-stage booster pump rated at 1-1/2 HP and 10 GPM. Manufactured by Xylem under the trusted Goulds name, it is purpose-built to provide the high, stable feed pressure that RO membranes rely on for consistent, efficient purification. The all-stainless wetted path makes it especially appropriate for feedwater chemistries that would shorten the life of pumps built with less robust materials, including waters with elevated chlorides or aggressive mineral content.

The multi-stage architecture yields smooth, quiet, and vibration-free operation, an important quality in commercial settings where pumps often run continuously and noise or vibration can become a real nuisance. Glass-filled engineered composite impellers and diffusers stand up to corrosion and abrasion, while 300-series stainless steel rabbit locks hold the bowls in precise alignment without gaskets, reducing potential leak points and simplifying service. The mechanical seal is available with various face materials and elastomers to match the application, letting integrators tailor the pump to the water it will handle.

Key Features

• 1-1/2 HP, 10 GPM stainless steel multi-stage construction
• Quiet, vibration-free operation ideal for continuous duty
• Corrosion- and abrasion-resistant composite internals
• O-ring casing seal for high-pressure sealing and easy disassembly
• Close-coupled NEMA 56J motor on ball bearings for thrust loads
• 1-inch NPT suction and discharge connections

Because every wetted component is selected for durability in treated and pre-treated water, the 10GBS15-SS is especially well suited to applications where water chemistry is aggressive. Its centrifugal design permits flow selection within a working range, and the motor is engineered for continuous operation. Adequate pre-filtration and a flooded suction help protect the seal and bearings and extend service life. Running the pump within its intended flow band, rather than throttling it severely, also keeps efficiency high and reduces heat and wear on the wetted components. Where source water is variable or seasonally harsh, the stainless wetted path provides a margin of durability that cast iron simply cannot match, making this model the safer long-term specification. This makes the pump a long-lasting, low-hassle choice for commercial RO integrators and facility managers who need dependable boost pressure they can count on day after day, year after year.
