Solids Handling Centrifugal Pumps
Two approaches can be taken when it comes to the basic centrifugal pump design for fluids containing solids and abrasive particles.
- To use a hard, wear-resistant material for the internal components such as PE or chrome.
- Reduce the velocity of the fluid in the pump chamber by using a slow and low shear pumping action.
AxFlow UK offer all of these options:
Warman recesed impeller and Wernert pumps are both available with hard wear resistant materials. The recessed impellers having the added benefit of reduced contact between the clay and the impeller due to the vortex created infront of the impeller.
The pumping action of Hidrostal screw centrifugal pumps features a long yet slow rotation of the screw/impeller resulting in a very low shear and delicate pumping action.
