In its simplest form a single screw rotates in a cylindrical cavity, thereby moving the material along the screw's spindle.
The two- and three Screw pumps are used to pump oils or other lubricating liquids, non-lubricating liquids, or liquids with poor lubricating properties. The characteristics of the screw pumps are: self-priming, very high efficiency, very low noise level and very well suited for use with variable speed drives (FU). The liquid is moved fully continuously, virtually without pulsations, without turbulence, crushing, or loss of lubrication.
