CLH Series Marine Vertical Ballast Water Pump

CLH Series Marine Vertical Ballast Water Pump

Introduction of CLH Series Marine Vertical Ballast Water Pump

CLH type water pump is a single-stage, single-suction, horizontal water inlet and horizontal water outlet vertical centrifugal pump designed in accordance with ISO international standards. The motor shaft and pump shaft are flanged for easy disassembly. Ballast pumps generally require large displacement and low head. Usually, the ballast pump is installed at the bottom of the ship and has a certain liquid column height, so it does not require dry suction capacity. Generally, a centrifugal pump or a reciprocating pump with a high specific speed is used. The CLH type water pump is suitable for use as a ballast pump for various ships.
