Screw Pumps
Our screw pumps are volumetric self-priming pumps suited to handle oils and liquids with a minimum lubricating quality. The design simplicity makes these pumps intrinsically reliable and efficient. Three screws rotate inside a replaceable casing with close tolerances, thus 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, thus 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, thus enabling 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 is guarenteed by a final testing on 100% of the manufactured products.
