Sigma motorised metering pumps and delta diaphragm metering pumps
The metering heads on Sigma motorised metering pumps and delta diaphragm metering pumps comply with stringent hygienic requirements.
The hygienic pumps are equipped with stainless steel pump heads. These fulfill all requirements according to European Hygienic Engineering & Design Group (EHEDG). The Research Center Weihenstephan for Brewing and Food Quality at Technical University Munich conducted special tests on the pump head in accordance with EHEDG cleanability methods. These tests ensure cleanability. The stainless steel pump head is EHEDG certified in combination with delta solenoid-driven metering pumps and Sigma motor-driven metering pumps.
The pump metering head with welded return valves are made of stainless steel 1.4404 or 316 L. The surfaces are polished and have a surface roughness of less than Ra = 0.8 µm.
The housing of the return valve consists of two parts, which are screwed together using a tri-clamp flange and the seal is created with a preformed PTFE gasket.
The metering diaphragm on the pump is made of PTFE and vulcanised rubber on the reverse. The surface is smooth and sealed.
Emptying the pump is easy as the fittings are arranged vertically.
