Grundfos BM Booster Modules

Grundfos BM Booster Pumps for Reverse Osmosis, Water Treatment, Pressure Boosting, and Industrial Water Systems

Grundfos BM Booster Pumps are compact multistage booster modules designed for high-pressure applications involving clean, thin, non-explosive liquids. The BM range is especially well suited for reverse osmosis, water treatment, pressure boosting, filtration, and industrial water systems where reliable pressure generation and corrosion-resistant construction are required.

The Grundfos BM is based on proven submersible pump hydraulics integrated into a stainless steel sleeve. This horizontal booster module design provides a compact alternative for applications where high discharge pressure is needed but installation space is limited. The pumped liquid flows around the motor, helping provide motor cooling during operation.

A key application for Grundfos BM Booster Pumps is reverse osmosis and membrane filtration. These processes require sufficient pressure to force water through membrane systems, making dependable high-pressure pump performance critical. BM modules can be used in water treatment and industrial systems for pressure boosting before or between treatment stages, depending on the system design.

Grundfos BM Booster Pumps are available in different configurations to accommodate application requirements, including BM and BMB variants. Their stainless steel construction makes them suitable for clean-water applications where corrosion resistance, compact installation, and reliable continuous-duty performance are priorities.
