Twin Screw Pumps

The working principle of Hydro Prokav dual flow Twin Screw Pumps is dependent on the rotation of the two screw spindles in the closed compartment. There is always a predefined fine clearance exists between the outside diameters of the screw spindles and the casing bore/ liner in which the screw spindles are located. Each half of the screw spindles is left handed and right handed thus when the spindles rotates, driven by the timing helical gears located at the end of the screw. The liquid is drawn towards the end of the screw and entrapped between the bore of the pumping compartment as well as the flanks of the screws and is then propelled axially from both the ends towards the centre. Such a dual flow nullifies the axial thrust completely, thereby enabling the screws to remain in a state of hydraulic balance resulting in high volumetric efficiency and overall efficiency.
