Hydraulic screw pump

oil

Three 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 guarenteed by a final testing on 100% of the manufactured products. Screw pumps: std according to API 676, for mineral and lubricating oils also fluids with low lubricating properties (water+oil, HFC, LFO, HFO). Flows up to 5,000 litres per minute and pressure upto 130 bar (200 bar peak).
