All of our Dry Pit/Bearing Frame pumps incorporate the screw centrifugal impeller, invented by Hidrostal. This hydraulic design offers considerable benefits over conventional centrifugal pumps, including:
Solids handling
Viscous pumping
Delicate handling
Low shear pumping
High efficiency operation
The unique characteristics of the screw impeller give a combination of characteristics not found in any other type of pump, namely:
Extremely steep and stable curve
High efficiencies
Non-overloading power curve
Low NPSH
Non-clog pumping
The term ""Non-Clog"" has almost become a punchline in the pumping industry. ...
Hidrostal compact pumps allow non-clog, trouble-free operation in demanding situations. They are used in slurry and wastewater applications, by emergency management/fire brigades, on construction sites and even in private households.
Compact Pumps - small, portable and ready to use whenever needed.
Hidrostal compact pumps are heavy duty field units which combine usability and robustness with the superior hydraulic and solids handling performance of the famous screw centrifugal impeller. This makes it the preferred pump for all types of municipal and industrial wastewater, slurry and mud applications, but also flood defense applications for portable/stationary installations.
Immersible Pumps Operate Continuously in Air and Under Water
Hidrostal Immersible pumps successfully handle difficult municipal and industrial wastewater. Viscous liquids, fragile flocs, and even live fish without problem.
Hidrostal's dry well immersible pumps have independent closed loop cooling that enables the motor to run either in a wet or dry well. As these immersible units do not use pumped media to cool the motors there are no problems of overheating due to slime build up in the cooling channel. The pumps are particularly suited for dry pit applications where the combination of the screw centrifugal impeller and immersible motor are the state-of-the ...
A method of matching pump outflow to pump station inflow without the need for additional flow control or additional electrical equipment such as inverter drives. A highly effective sump cleaning system without the need for any additional mechanical or electrical items, such as grinders, bar screens or mixers.
Product Advantages:
Matches station outflow to inflow using fixed-speed motors
Automatically removes floating and settled solids
Shallower pump stations [compared to submersibles with On-Off controls]
