Marine screw pumps are positive displacement pumps designed for transferring viscous fluids in marine applications. They feature rotating screws that create a steady flow with minimal pulsation and high efficiency. These pump systems are commonly used for fuel, lubrication, and cargo handling on ships and offshore platforms.
