Diaphragm pump in action
The MD 1 diaphragm pump is an excellent choice for oil-free evacuation and pumping of non-corrosive gases down to 1.5 mbar ultimate vacuum. The three-stage design with precisely guided flat diaphragms provides outstanding pumping speed even close to the ultimate vacuum, especially when compared with similarly rated two-stage diaphragm pumps. The MD 1 is an ultra-low vibration pump with very long diaphragm lilfetime and stable ultimate vacuum documented with years of testing. With a flow path consisting of aluminum and selected plastics (diaphragms and valves made of PTFE/FKM and FKM, respectively) the pumps are suitable for a wide range of applications with non-corrosive gases. The MD 1 is an excellent choice for continuous, oil-free evacuation and pumping of non-aggressive gases. It is suitable for high vacuum requirements at modest gas flow as often needed in physics and analytics. The pump is exceptionally quiet and reliable with long diaphragm and valve lifetimes. With its low ultimate vacuum and compact dimensions the MD 1 is widely used as replacement of rotary vane pumps. Typical applications are exhaust gas analysis, for degassing of small amounts of viscous media and in particular as backing pump for compact turbomolecular drag pumps. Back diffusion of oil or even oil back flow, e.g., into a high vacuum chamber is excluded due to its oil-free operation. For equipment manufacturers customized versions are available.
