Vacuubrand Diaphragm Pump MD 12 NT VARIO


Vacuubrand Diaphragm Pump MD 12 NT VARIO

These oil-free diaphragm pumps are particularly powerful pumps for the evacuation and pumping of non-aggressive gases. The three-stage design combines particularly high pumping, with excellent ultimate vacuum of up to 2 mbar, and up to 1.5 mbar with the VARIO version. It provides precise control and always consists of the pump and the CVC 3000 vacuum control unit with an external indicator head. For use as a booster pump, it has a continuous adaptation of its speed for optimum life. The highly flexible, fabric-reinforced double diaphragm made of FKM provides increased operating life at speed below engine speed.

Like all VACUUBRAND diaphragm pumps, they create an absolutely oil-free and clean vacuum as they operate without non-slip seals. For this reason, leachable dust formation to high vacuum application, which is often found in scroll or piston pumps, is excluded.
