Solids handling pumps

The Hidrostal screw centrifugal impeller is able to pass solids and handle rags and fibrous material whilst at the same time avoiding compromising the hydraulic design. This impeller design offers many benefits including low shear, and a relatively steep, stable performance curve.

The range includes submersible / immersible pumps in standard or ATEX construction, end suction pumps for horizontal or vertical mounting and portable self priming pumps with electric or diesel engine drives with wet ends.  Pumps are available in a variety of materials and configurations suited to a clients requirements. 

Of particular interest to the water and waste industry is the PreroClean self-Cleaning Sump, which removes floating and settled solids at the end of every pumping cycle and the Prerostal™ flow matching system that matches outflow to inflow without the need for variable speed drives.  

Other popular solutions based on the screw centrifugal pump include Hidrostal’s VO² Venturi aeration systems and tank/digester mixing systems.
