Marine Ballast Pump
Ballast water pumps are pumps used for filling or draining ballast tanks. Also called ballast pump.
The injection and discharge of ballast water and the allocation between each tank are realized by the allocation valve box through the self-flow or ballast water pump.
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. Depends on restrictions.
