Screw Pumps Manufacturers

Screw pumps are rotary positive displacement pump in which the flow through the pumping elements is truly axial. Fluid is transferred through successive contact between the housing and the screw flights from one thread to the next. The liquid is carried between the screw threads on one or more rotors. Screw pump has an axial flow pattern and low internal velocities. These pumps transfer fluid by displacing the oil axially through a closely fitted chamber formed between the screw recess and housing wall. These pumps are classified as two different types: the single rotor and multiple rotors. A classic example of screw pumps is the Archimedes screw pump that is used in irrigation and agricultural applications. Screw pumps provide a specific volume with each cycle and can be dependable in metering applications.
