HIDROSTAL

Being the inventors of the screw centrifugal impeller in the 1960s, Hidrostal is a company totally dedicated to its development and improvement.   The continuous R & D programme has lead to a family of pumps being developed all incorporating the screw centrifugal impeller with subtle variations to the design in order to optimise the benefits for a wide range of applications.

Services offered include:

• The key applications being
• Excellent solids handling
• Gentle handling
• Low shear
• Pumping viscous liquids

The Hidrostal pump 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. All pumps can be supplied in a variety of materials which best suit the application. 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.
