Pump Solutions (Verder Pumps)
Verderhus Screw Channel Centrifugal Pumps
Working Principle
- A corkscrew shaped impeller lays in a cone shaped casing.
- The screw rotates and induces the fluid onto the impeller
- The impeller then pushes the product out of the pump
The Benefits of Screw Channel Pumps
- Retains % efficiency with increasing viscosity to 1000 CPS
- Gentle, low shear pumping action
- Reduced pump transit time reduces abrasive wear =reduced maintenance costs
- Externally Adjustable Clearances optimize pump efficiency = reduced energy costs
- Able to pump large Ø solids due to impeller design
- Much reduced clogging due to smooth liquid path
- Lower NPSHr
