SAWA block pumps are made of 316L / 1.4435 stainless steel. SAWA Pumpentechnik AG combines consulting, development and production of high-quality block pumps under one roof. With an efficiency of up to 75%, the pumps are successfully used in a wide range of industries and meet the EHEDG guidelines of the pharmaceutical and food industries. The bolted and very thick-walled housing designs promise a very high degree of robustness and process reliability. SAWA close-coupled pumps are manufactured with IEC standard motors. The stub shaft is simply pushed onto the motor shaft, is easy to position and very easy to fix. Thanks to the balanced stub shaft as well as the flow-optimised impeller/housing geometry, optimum concentricity is guaranteed and noise development is reduced to a minimum.
