Product Description

Largely demanded for offshore and marine installations, these Three Screw Pumps are often used to pump high-pressure viscous fluids. The three screws drive the pumped liquid forth in a closed chamber. As the three screws rotate in opposite directions, the pumped liquid moves along the screws spindles. Three Screw Pumps are suited for a variety of applications such as oil burners, boosting, hydraulics, fuel-injection, fuel, lubrication, circulating and feed. The screws intermesh and run inside of the pump housing.
