Screw pumps

Screw pumps are positive-displacement rotary pumps with an axial flow design that has only three moving parts. Power rotor is the only driven part that extends outside of the case. Idler screws act as sealing parts and are turned hydraulically by the fluid being pumped.

There is only a rolling action between the drive screw and the idler screw, which eliminates noise and vibration, ensuring a long life. Two models are rated for 40 and 80 bar. They offer constant flow, even in the presence of varying system backpressures.
