The parts that are in contact with the medium are made of 316 stainless steel, allowing it to withstand extreme applications at construction, aggregate and mining. The cylindrical and slim design, allow for installation in a well casing for deep well dewatering. The center flange construction assures a stable installation even if it is fixed by the discharge pipe. The pump is equipped with seal pressure relief ports that prevent the pumping pressure from damaging the shaft seal.
