The
Screw Centrifugal Impeller
Hidrostal's
screw centrifugal impeller pump is a unique and patented solution
to the problems of efficiently handling either very delicate
materials or a broad range of thick and viscous liquids, often
highly abrasive or corrosive in nature.
The impeller has a single blade, axially
extended at the inlet and developed around its axis much like
a corkscrew, linking this to a centrifugal outlet and allows
pumping with the minimum of agitation and shear, essential
factors when product bruising, liquid emulsification or clogging
are to be avoided.
The screw centrifugal impeller pump provides
several key benefits…
Large free
passages for pumping liquid with solid objects and fibrous
material.
Able to pump liquids with
viscosities above values normally possible with conventional
centrifugal pumps.
Steep H/Q curves with
closed valve twice best efficiency point.
