PDF datasheet mirror for BM 4" - BM 6" - BM 8" (Grundfos Pumps). Verify with OEM before design.
Summary
Product identification
The Grundfos BM booster module is a high-pressure booster module available in 4", 6", and 8" sizes, suitable for 50 Hz and 60 Hz operations. These are Grundfos high pressure booster modules.
Applications
Grundfos BM booster modules are designed for boosting, liquid transfer, and circulation in systems under high static pressure. They are suitable for industrial and water supply applications requiring increased system pressure. Typical applications include:
- Water treatment, particularly ultra-filtration and reverse osmosis.
- Production of fresh water from sea water (desalination).
- Pressure boosting.
- Closed circulation systems with a high static pressure.
- Reverse osmosis in domestic water supply, hospitals, laboratories, the chemical, electronics, and metal industries.
- Ultra-filtration in chemical and galvanic industries, painting workshops, the metal, and mineral industries.
These modules are an optimum solution for applications requiring:
- Sealless pumps
- Pumps able to cope with high system pressures
- High pump heads
- Silent operation
- Operation with a minimum of maintenance
Operating limits
- Flow:
- 50 Hz: Max. 160 m³/h, 704 USGPM
- 60 Hz: Max. 180 m³/h, 793 USGPM
- Head: Max. 470 m / 1542 ft
- Temperature: Max. 40 °C / 104 °F
- Outlet pressure: Max. 80 bar / 1160 p.s.i.
- Suction pressure: Max. 60 bar / 870 p.s.i.
Customised pumps are available for applications requiring higher temperatures or flow rates. Contact Grundfos for further details.
