Weir Specialty Pumps applies advanced pump design technology to increase product performance, reduce cost and improve lead time. The long-established screw centrifugal design provides clog-resistant pumping for trouble free movement of solids, and fibrous and stringy materials.
The Original Screw Centrifugal Pump was Invented by Martin Staehle. In the 1950s Martin Staele invented and developed the first Hidrostal Screw Centrifugal Pump in Lima, Peru.

Design standards n/a Design ratings n/a Size range/ -dimensions 3 to 10 inch Pressure class/ -power 6 to 270 feet (2 to 82 metres) Temperature range 32ºF to 180ºF (0ºC to 82ºC) Capacity 150 to 10000 GPM (34 to 2275 m³/hr) Advantages of the WEMCO® Screw Centrifugal. Low NPSH: The screw portion of the WEMCO® Screw Centrifugal impeller performs as an inducer, pulling liquid into the impeller, resulting in low NPSH requirements.
Solids Handling: The single vane impeller of the WEMCO® Screw Centrifugal pump creates a single channel flow, allowing for larger solids passage. The large solids passage provides better solids handling capabilities than any other pump type. The steep head-capacity curve provides ample reserve pressure to clear temporary clogs. Sludge Handling Positive Suction: The combination of a low NPSH requirement and large solids channels provides a powerful pump for handling thick sludges. The steep head-capacity curve of the WEMCO® Screw Centrifugal pump also allows for pumping of varying sludge consistencies without the need to change speed. An additional benefit is the reserved head for clearing temporary line blockages.
Adjustable Liner: Consistent impeller to liner clearance is imperative to the performance of the pump. As the pump components wear, clearance between the impeller and liner can be adjusted to ensure optimal performance.

Hidrostal Pump Manual
The Original Screw Centrifugal Pump was Invented by Martin Staehle In the 1950s Martin Staele invented and developed the first Hidrostal Screw Centrifugal Pump in Lima, Peru. This design has proven itself through the years and been put to the test in a wide range of applications.
Due to their outstanding characteristics, Hidrostal pumps are used in numerous municipal and industrial sectors all around the world. Our pumps are custom-made and are specially tailored to the needs of each location. Our specialists select the suitable material combinations and individually adapt every pump to the local conditions. We ensure with this process that Hidrostal pumps are successful in difficult applications and achieve the best results with respect to performance, energy efficiency and low life-cycle costs. There are many imitation screw centrifugal pumps, made by just as many companies, but there is only one original.
Do not be fooled by marketing lingo designed to fool you. For many years Weir Salt Lake City© (WEMCO©, Weir Power and Industrial©, etc.) used to represent Hidrostal to the United States and Canada. All the pumps they sold up to 2015 were made by Hidrostal, and now they market their own pump, which does not share the same time tested performance as the original. If you want the best screw centrifugal pump, trust the original! Springer Pumps for more information or a quote today. Clog-free pumping. High suction capacity.
