Screw Pumps

General Description

TheTtwo- and  Three Screw pumps are used to pumpoils or other lubricating liquids, non-lubricating liquids, orliquids with poor lubricating properties. The characteristics of the screwpumps are:self-priming, very high efficiency,very low noise level and very well suited for use withvariable speed drives (FU). The liquid is moved fullycontinuously, virtually without pulsations, without turbulence,crushing, or loss of lubrication.

Functionality

Single- / -double channel, self-priming; the spindles have specialshapes that create sealed chambers, the contents of whichare continuously moved in an axial direction from the suctionside to the pressure side as the spindles rotate. Despite rotationof the spindles, no turbulence results.

The uniform chamber volumes eliminate crushing forces.
