Check up to five results to perform an action.
The screw/centrifugal impeller with open channel design - combines the Clog-free features of a vortex pump the gentle action of a screw pump and the high efficiency of a centrifugal pump
The screw section produces positive action, In clear liquid, it performs like an Archimedes spiral. In thick sludges, slurries, and suspended solids, it burrows like a corkscrew to start material moving and keep it moving.
The centrifugal section produces steep head-capacity curve for non- overloading performance.
Combined, the screw/centrifugal action provides high, hydraulic efficiencies and clog-free pumping. The large, continuous open channel - from suction to discharge - makes it possible to handle large, soft solids with efficiencies of more than 80%.
