Goulds Booster Pump, CI, 1.5 HP, 10 GPM

The Goulds 10GBC15-CI is a horizontal, multi-stage booster pump built by Xylem for the demanding world of commercial reverse osmosis. Pairing a 1-1/2 HP motor with a 10 GPM rating, this pump features stainless steel construction with cast iron ends, delivering the steady, high-pressure feed that RO membranes require to produce purified water efficiently and reliably. In a commercial RO system, the booster pump is what allows the membranes to achieve their rated rejection and recovery, making the right pump selection critical to overall water quality and to the consistency of treated-water output.

Engineered for RO Performance

The multi-stage design produces smooth, quiet, vibration-free operation, while glass-filled engineered composite impellers and diffusers resist the corrosion and abrasion common in water-treatment service. An O-ring casing seal provides dependable high-pressure sealing and allows straightforward disassembly when maintenance is needed. Inside, 300-series stainless steel rabbit locks keep the bowls in positive alignment with no gaskets required, simplifying both assembly and long-term upkeep. The mechanical seal can be matched with various face materials and elastomers to suit specific application needs and feedwater conditions.

• 1-1/2 HP, 10 GPM horizontal multi-stage pump
• Stainless steel build with durable cast iron pump ends
• Composite impellers and diffusers resist corrosion and abrasion
• O-ring casing seal for reliable sealing and easy service
• Close-coupled NEMA 56J motor rated for continuous operation
• 1-inch NPT suction and discharge connections

Designed specifically for commercial RO systems, the 10GBC15-CI provides the consistent boost pressure needed to keep production rates stable as feedwater conditions change. Its centrifugal design allows flow selection within a usable range, and the close-coupled motor rides on ball bearings that carry radial and axial thrust loads for dependable, around-the-clock duty. When sizing, confirm the suction supply and downstream membrane requirements so the pump operates near its efficient point. Adequate pretreatment, a flooded suction, and clean prefilters all help the cast iron ends and mechanical seal reach their full service life under continuous load. The horizontal layout also keeps the footprint compact and the connections accessible, which simplifies skid mounting and later servicing in tight equipment rooms. For integrators and facility operators building or servicing a commercial reverse-osmosis system, this Goulds pump is a proven, serviceable choice that balances performance with long-term reliability and predictable, stable membrane feed pressure.
