Product catalog summary

Technical Specifications
Grundfos BM and BMB booster modules are available in 4”, 6”, and 8” sizes, suitable for both 60 Hz and 50 Hz frequencies. The maximum flow rates are 1475 gpm (335 m3/h) for 60 Hz and 1233 gpm (280 m3/h) for 50 Hz. The maximum head is 1595 ft (486 m). The liquid temperature range is from +32°F to +104°F (0°C to +40°C). The working pressure for BM modules is up to 1160 psi (80 bar), while for BMB modules, it is up to 870 psi (60 bar).

Applications
These booster modules are suitable for pressure boosting in reverse osmosis systems, water supply systems, water treatment systems, industrial plants, and high-pressure washing.

Features and Benefits
The modules offer low noise operation, handle high pressures and heads, are easy to install, have a compact and modular design, are sealless, and require low maintenance.

Construction
The BM and BMB booster modules use modified standard submersible pumps centered in a stainless steel sleeve, with victaulic couplings for piping connections. The 4” size is available with both straight and 90° bend configurations.

Connections
Various models are available with different victaulic coupling sizes, ranging from 1 1/4” to 6”, depending on the module size and type.

Installation Configurations
Booster units can be configured with modules connected in series, parallel, or a combination of both, with options for bypass connections.
