The MD 12 diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non aggressive gases. The three-stage construction of the eight-head pump provides the advantageous combination of very high pumping speed and very low ultimate vacuum. The flowpath consists of aluminum, stainless steel and carefully selected plastics (diaphragms and valves made of FPM) to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FPM for extended operating life. The special ("double star") design offers quiet, continuous-duty reliability even at high inlet pressure.
