The pump with the characteristic screw centrifugal impeller was invented by Hidrostal founder, Martin Stähle and patented in 1961. 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 centrifugal impeller and today, offers tailored designs for various application areas.
