BM, BMB (Booster modules 4", 6", and 8")

Product catalog summary

Technical Specifications
The GRUNDFOS BM and BMB booster modules are available in 4”, 6”, and 8” sizes, compatible with 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 BM modules can handle a working pressure of up to 1160 psi (80 bar), while the BMB modules can handle up to 870 psi (60 bar).

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

Features and Benefits
Key features include low noise operation, the ability to handle high pressures and heads, simple installation, a compact and modular design, sealless construction, and low maintenance requirements.

Construction and Design
The BM and BMB modules utilize modified standard submersible pumps centered in a stainless steel sleeve, with victaulic couplings for piping connections. The 4” modules are available with either straight or 90° bend configurations. The pumps feature an asynchronous submersible squirrel-cage motor with water-lubricated bearings.

Connections
The modules use victaulic couplings with varying sizes depending on the model type, ranging from 1 1/4” to 6”.

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