Dry rotary lobe vacuum pumps are ideal for clean, maintenance-free, roughing pump applications. These pumps differ from the conventional rotary blower in that lubricants are isolated from the vacuum environment. We carry new and rebuilt multistage, dry rotary lobe vacuum pump units from Alcatel Adixen, Ebara, and Leybold for both normal or corrosive atmospheres. Please contact us if your pump requires professional service.
