There is also a three spindle screw pump commonly used in the offshore and marine industries to move high-pressure viscous fluids. The screws do come into contact with each other, which often limits the pump to handling only clean liquids. Three screw pump (triple screw pump) – They utilize one driving screw intermeshed with the other two screws to create pressure and move fluid.Due to the design, the screws are not required to be in direct contact with each other which helps extend the life of the pump. The pump is often equipped with timing gears located outside the pumping chamber that are lubricated with oil in order to ensure the two screws are rotating properly. ![]() Two/Double screw pump (twin screw pump) – These pumps operates by using two intermeshing screws as described above. ![]() There are two main types of screw pumps in common use today: The screws take in fluid then push it out from the other side while increasing its pressure. ![]() A screw pump is a type of positive displacement pump that uses two or more screws that intermesh to pressurize fluids and move them in a system.
