Screw pumps suited to handle oils and liquids with a minimum lubricating quality

SCREW PUMPS
These screw pumps are volumetric self-priming screw pumps suited
to handle oils and liquids with a minimum lubricating quality.
The design simplicity makes these screw pumps intrinsically reliable and efficient.

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).
Motor pump sets: close coupled, AC or DC electric motors.
Pre-assembled systems: with bell-housing and coupling arrangements.
Skid mounted pumps: with or without motor but suitable for horizontal or vertical mounting.
High efficiency Air/Oil Heat Exchangers: upto 14,000 kCal/h (16kW)
Relief valves: Flow rate from 50 to 1,200 litres per minute and pressure up to 40 bar
