VACUUBRAND MD 1 diaphragm pumps are 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 a long diaphragm lilfe 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.
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.
