What is Submerged Pump?
Submerged pump is a type of centrifugal cargo pump commonly installed on gas carriers and in terminals in the bottom of a cargo tank, i.e. with drive motor, impeller and bearings totally submerged when the tank contains bulk liquid.
Examples of Submerged Pump
Submerged pumps are used on LNGC and the low temperature of the cargo is used as a cooling medium for the submerged electric motor. The pump assembly and electric motor are installed in the bottom of the cargo tank.
