GRUNDFOS DATA SHEET BM 4", 6" and 8" - 50 Hz and 60 Hz Grundfos high pressure booster modules are used for boosting, liquid transfer and circulation in systems under a high static pressure. Reverse osmosis in domestic water supply, hospitals, labo- ratories, the chemical, electronics and metal industries. Ultra-filtration in chemical and galvanic industries, painting workshops, the metal and mineral industries. Applications Introduction The Grundfos BM booster module is suitable for industrial and water supply applications requiring increased system pressure. For applications requiring ... • sealless pumps, • pumps able to cope with high system pressures, • high pump heads, • silent operation, • operation with a minimum of maintenance. Grundfos BM booster modules are the optimum solution. Typical applications Typical applications for BM booster modules are: • 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. Operating conditions Flow: 50 Hz: Max. 160 m 3 /h, 704 USGPM, 60 Hz: Max. 180 m 3/h, 793 USGPM. Head: Max. 470 m/1542 ft. Temperature: Max. 40°C/104°F. Outlet pressure: Max. 80 bar/1160 p.s.i.
