Hidrostal pumps
Hidrostal Free Flow Technology
PRODUCT LINE
Engineered Wastewater Pumps
This range features a more traditional wastewater design that features a shrouded, mulit vane impeller and is available in either a Dry-Pit/Bearing Frame design with mutliple instalation configuration in either a horizontal or vertical position.
Prerostal Self Cleaning Wet Well System
The PREROSTAL® and PreroClean™ Prerotation system is a unique, economical, uncomplicated method of automatically adjusting pumping volume to varying inflow rates using a constant speed motor and pump.
Fish Friendly Pumps
Our founder patented the first ever Fish Friendly Pump over 50 years ago. Our current range includes both Fish Friendly Pumps and Fish Transfer Pumps that are suitable for a wide variety of sizes and species fish.
Hidrostal Portable Screw Impeller Pump Model A2Q
The pump was originally developed for use in the fisheries industry to transport fish from the boat for further processing without damaging them. This pump design was a tremendous success and widely imitated once the patent expired. Since then Hidrostal has continued to refine the Screw Cenrtifugal Impeller and today, offers tailored designs for almost all application areas.
End Suction Screw Centrifugal Pumps
Dry Pit/bearing frame pumps incorporate the screw centrifugal impeller, invented by Hidrostal. This hydraulic design offers considerable benefits over conventional centrifugal pumps.
Immersible Pumps
Immersible pumps operate reliably
in dry and wet installations.
Axial Flow Tube Pumps
Hidrostal Axial-Flow type pumps are designed for low head applications up to 30 ft TDH and flows from 500 GPM to 20,000 GPM.
Diesel Portable Self Priming Pumps
Comprised of a Hidrostal end suction pump with solids handling capabilities, viscous handling properties and high hydraulic efficiencies, the Betsy far outclasses rivals when pumping raw and untreated sewage water.
Hidrostal Hidromix Pump
The HIDRO-MIX Sludge tank mixing system is built upon the Hidrostal screw centrifugal pump, renowned for its rag and sludge handling capabilities, and replaces the traditional methods of mixing sludge storage tanks and anaerobic sludge digesters. Unlike other mixing systems, the Hidrostal concept does not require structural steelwork within the tank. The system is mounted at ground level and fixed to the outside of the tank. Large diameter nozzles are installed externally through the tank walls. The systems have simple pipe work designs with short pipe runs, resulting in minimal friction losses and the maximum energy imparted to the fluid.
