Hydraulic screw pump PO, PWO Series

fuel oiloiltransfer

PO - PWO Series screw pumps for coolant pump for machine tools, deep hole drilling, light oil fuel pumps, fuel transfer. Mineral and natural oils, low-viscosity fuel fluids. Flow rate up to 600 L/min. Maximum delivery pressure (continuous) = 100 bar at 2900 rpm Epicycloidal screws rotate inside a replaceable casing with close tolerances, so forming sealed chambers and provoking the axial displacement of the fluid. The idler spindles rotate without contact with the driving spindle because of the fluid itself, therefore being free from radial forces. The accurate hydraulic balance and the special profile of the screw thread guarantee a continuous flow with minimum pulsations and turbulance, resulting in extremely low noise levels even at high rotational speed. The screws epicycloidal profiling is developed through a complex computerised calculation which not only perfectly defines their shape, but also controls the production with continuous monitoring of machinery process, consequently assuring a high degree of repeatable quality. The high quality level of these screw pumps is guaranteed by a final testing on 100% of the manufactured products.
