Three Screw Pumps

The three screw design is positive displacement rotary design pump. These pumps are commonly used for machinery lubrication, hydraulic elevators, fuel oil transport, powering hydraulic machinery, refinery processes, and high pressure coolant service for machine tools. Screw pumps use an Axial flow multi-rotor positive displacement pump design. Two symmetrically opposed idler rotors act as rotating seals confining the fluid in a succession of closures of stages. The idler rotors are in rolling contact with the central power rotor and are free to float in their respective housing bores on a hydrodynamic oil film.

Features:

  • Quiet operation typically noise levels are below 75 dBa at 3 ft.
  • High speed capability. No rubbing parts. This allows the use of a smaller, less expensive pump.
  • Delivers non-pulsating flow.
  • Excellent suction lift and low horsepower consumption
