TheTtwo- andá Three Screw pumps are used to pump
oils or other lubricating liquids, non-lubricating liquids,
liquids with poor lubricating properties. The
characteristics of the screw
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
crushing, or loss of lubrication.
Single- / -double channel, self-priming; the spindles have
shapes that create sealed chambers, the contents of which
are continuously moved in an axial direction from the
side to the pressure side as the spindles rotate. Despite
of the spindles, no turbulence results.
The uniform chamber volumes eliminate crushing forces.
