ATMP-B-1250-3 High-Pressure Booster Pump
Energy Recovery · ATMP-B-1250 Series · 3-Stage
The Energy Recovery ATMP-B-1250-3 is a high-pressure booster pump for seawater reverse osmosis. It takes already-pressurised brine from the energy-recovery device and restores the head lost across the exchanger, so it is rated for a high inlet pressure as well as a high outlet pressure.
