The two and three-spindle screw pumps are used to pump oils or other lubricating liquids, non-lubricating liquids, or poorly lubricating liquids. The characteristics of the screw pumps are: two or three spindles, 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.
Single channel, self-priming; the three spindles have special shapes that create sealed chambers, the contents of which are continuously moved in an axial direction from the suction side to the pressure side as the spindles rotate. Despite rotation of the spindles, no turbulence results. The uniform chamber volumes eliminate crushing forces.
