The Hidrostal hydraulic system reliably and efficiently solves pumping problems in all application areas. For more than 60 years, Hidrostal pumps with their original screw impeller have been pumping wastewater, liquids with a high solid content, foodstuffs, slurry and sludge, fibrous materials, abrasive and gaseous media and much more.

Energy efficiency is the key for today’s pumping business. Therefore all manufacturers make promises about efficiency levels, especially for electric motors. The question is, if they are applicable for submerged wastewater pumps.
