Hidrostal Screw Centrifugal Immersible Pumps are capable of continuously operating in a dry installation. They run with equal performance either in air, fully or partially submerged.
Hidrostal Immersible Pumps successfully handle difficult municipal and industrial wastewater. Viscous liquids, fragile flocs, and even live fish pose no problem.
Long trouble-free operation
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 art technology. Leakage of the pumped product is eliminated by tandem seals running in an oil bath, avoiding a situation commonly experienced with soft-packed glands. Hidrostal immersible waste water / sewage pump stations have frequently been mistaken for clean water stations, due to the lack of odor and the cleanliness of the buildings. Immersible pumps are particularly suitable for installation where quiet running, clean surroundings, reliable and long trouble-free operation are required.
