Marine Progressive Cavity Pumps are positive displacement pumps designed for handling viscous, abrasive, and shear-sensitive fluids in marine applications. They feature a helical rotor and stator system for smooth, pulsation-free flow, ideal for fuel transfer, bilge pumping, and waste management. These pump systems are known for their durability, efficiency, and ability to handle challenging marine environments.
