KIESEL eccentric screw pumps are self-priming positive displacement pumps. Among other things, they are used where products are too viscous and hardly flowable to be pumped by other pump types. Even fibrous, solids-laden material is transported safely. They are available in various performance classes and material combinations.
The eccentric screw pump consists of a rotating element, the displacement body (rotor) and a static element (stator). The rotating part has the shape of a round single-start worm shaft with a large pitch. The stator has the shape of a two-start internal screw and thus the double pitch of the rotor.
As a result, there are cavities between the rotor and stator, which always have the same size during the rotation of the rotor. If the rotor is now set into a rotary motion, these cavities (and consequently also the medium to be pumped) are “pushed” helically from the suction to the discharge side.
KIESEL eccentric screw pumps have an extremely wide range of application areas. Since 1965, they have proven themselves worldwide in a wide variety of industries for continuous, pressure-stable, gentle and low-pulsation delivery of almost all free-flowing media.
