  WORKINGPRINCIPLE: Three Screw pumps employ just three screw elements - one power screw andtwo idler screws running in the three precision bores in the housing or liner.The screws are so profiled that they form a liquid tight seal between thethread. As the screws rotate, pockets/ cavities are formed where liquid getstrapped and conveyed from one end of the infinite stroke. This results insmooth, pulsation free flow with extremely low noise and vibration levels,almost impossible to be achieved by any other design of positive displacementor other types. The power rotor does not drive the idlers as commonly believed.The hydraulic forces acting on screw flanks turn the idlers torquelessly thusreducing the friction. The idlers simply roll over the root diameter of idler dia.reduce the unit pressure, centralize the power rotor and absorb the radialloads. A balance piston integrally machined on power rotor takes care of axialthrusts. While in operation, the screws are in hydrodynamic balance on filmlubrication and do not require any additional bearings. The one ball bearingoften used is only for axial positioning of rotor and safer operation ofmechanical seals. Small rotor dimensions enable the pump to be operated at highspeeds directly coupled 3000 or 3600 RPM motors or other prime movers. Suchunique design and features has demonstrated excellent reliability with pumps inoperation continuously non-stop for decades together without replacement of anycomponents or maintenance on clean fluids.
