Description
These oil-free diaphragm pumps are especially powerful pumps for evacuation and pumping of non aggressive gases. The three-stage design combines especially high pumping speed with excellent ultimate vacuum down to 2 mbar, and down to 1.5 mbar with the VARIO® version. It provides precise vacuum control and consists always of the pump and the CVC 3000 vacuum controller with external gauge head. For the use as backing pump it features continuous adaptation of running speed for optimized forevacuum. The highly flexible, fabric-reinforced double diaphragm made of FKM offers extended operating life that increases significantly in motor speed controlled operation. Like all VACUUBRAND diaphragm pumps they generate an absolutly oil-free and clean vacuum as they work without any sliding seals. Hence generation of dust that might creep back into the high vacuum application, as often found with Scroll or piston pumps, is excluded.
