General Description
The spiral-centrifugal pump can go beyond the limits of classical centrifugal pumps, and even into the application area of positive displacement pumps. The construction is suitable for the handling of solids in suspension and viscous liquids, as well as for applications with larger negative suction heads.
The shape of the inlet edge creates an "inducer effect", which makes a large negative suction head possible (or a higher transportation media temperature). A pronounced screw shape creates a displacement effect with high viscosities, which makes possible the handling
of viscous liquids well into the displacement pump application range.
