Marine and industrial use for hydraulic and lubricating oils.
Handled fluids: mineral and synthetic lubricating oil; hydraulic oil; diathermic oil; DFD-U and HFDR phosphate organic esters; glycols; heavy and light fuels. Viscosity range from 10 to 5000 cSt. Pump speed from 750 to 3600 rpm. Rotation (viewed from coupling end): CW (Std version; CCW on demand).
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.
