Hidrostal – The ORIGINAL Screw Impeller Pump for more than 60 years! The Hidrostal screw centrifugal pump was originally invented and developed by Martin Staehle, the founder of Hidrostal. With production facilities in Switzerland, Peru and elsewhere, Hidrostal manufactures a complete line of screw centrifugal pumps and immersible motors to handle today’s tough wastewater and sludge demands with time tested and proven designs.
