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 a very long diaphragm lifetime 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. 

Diaphragm pumps from VACUUBRAND feature construction with fluoropolymers which makes them very resistant to chemical vapors from inlet to exhaust. In this pump technology, pumping chambers are hermetically separated from the drive system. All wetted parts are made of selected fluoroplastics. They are characterized by excellent chemical resistance and low material adhesion.

VACUUBRAND diaphragm pumps offer unsurpassed long-time performance – even in rough conditions. Thanks to high-quality fluoropolymers, precise manufacturing processes, and 100% quality control, VACUUBRAND diaphragm pumps guarantee long service intervals, and longstanding reliability.

VACUUBRAND diaphragm pumps stand for unrivaled years of reliability. To achieve this, they use a special diaphragm technology and carefully selected materials. The most heavily stressed components are produced in a complex, multi-stage manufacturing process.

As the result of multi-year performance tests, VACUUBRAND has determined a typical diaphragm service life of 15,000 operating hours for our pumps. Thanks to the maintenance friendly design, diaphragms and valves can be easily changed. VACUUBRAND diaphragm pumps are therefore touted to run for many years with high reliability and require only minimal maintenance.
