In the 1950s, Hidrostal’s company founder, Martin Stähle, learned of a demanding conveying task. The task was to quickly convey live fish with as little damage as possible. This task set his inventive genius to work and he developed the so-called screw centrifugal impeller pump, which he patented. In the decades to come, Hidrostal solved numerous challenging conveying tasks around the world. The products that were developed always catered to the specific needs of the customer. Today, Hidrostal is not only capable of series production on the basis of designs, which can be optimally combined, but also highly individual solutions.
