The MD 12 NT diaphragm pump is an especially powerful pump for oil-free evacuation and pumping of non aggressive gases. The three-stage design of this eight-cylinder pump provides the advantageous combination of very high pumping speed and excellent ultimate vacuum. The flow path consists of aluminium, stainless steel and carefully selected plastics to permit a wide range of applications. The fabric-reinforced double diaphragms are made of highly flexible FKM for extended operating life and high vacuum performance. Eight-cylinder NT pumps feature quiet operation, with smooth and easy-to-clean surfaces. Like all VACUUBRAND diaphragm pumps they operate absolutely oil-free and do not have any sliding components in the gas path. In normal operation they are completely free of abrasion.
