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.
Design Features
> Non-blocking
> High suction head
> Low shear force, soft conveying
> High efficiency
> Stable and steep curve
> Long service life
> Low disturbance
> Flow proportional to the speed
> Stable operation in a wide speed
Operation Conditions
Fluid: Raw sewage and industrial wastewater without grid filtration, long fiber, transporting activated sludge without damaging biological bacteria, transport sludge with a solid content of up to 18%.
> Working Temperature Range: -10ºC ~ 80ºC.
When working temperature exceeds 80ºC,shall clarify clearly and in advance.
> Operating pressure:
PN1.0 MPa - Hydrostatic test pressure = PN1.6MPa
