Product description
Diaphragm pump MZ 2D NT is a two-stage, oil-free pump designed for continuous pumping and evacuation of non-corrosive gases. All wetted parts are made from aluminum, stainless steel and selected plastics to ensure chemical compatibility for a wide range of industrial applications. The two-stage design combines a favorable pumping speed with an ultimate vacuum down to 4 mbar. Fabric-reinforced FKM double diaphragms provide high flexibility and extended service life. The NT series features improved performance and a compact footprint, suitable as a roughing or process pump in laboratory and industrial vacuum systems.
