The new hygienic Pumps are equipped with stainless steel pump heads. These fulfill all requirements according to EHEDG (European Hygienic Engineering & Design Group). The Research Center Weihenstephan for Brewing and Food Quality at the Technical University of Munich conducted special tests on the pump head in accordance with EHEDG cleanability methods. These tests guarantee perfect cleanability. The stainless steel pump head is EHEDG-certified in combination with Sigma motor-driven metering pumps.
