Service life improved for rotary vane pumps

Selecting equipment that’s built to last can help keep maintenance costs in check. Pfeiffer Vacuum’s new two-stage Duoline rotary vane pumps have long maintenance intervals, energy efficient motors and optional oil return resulting in low operating costs. The integrated, hydraulically controlled high-vacuum safety valve increases operational reliability. Suitable for applications in the low and medium vacuum range, the pumps’ reduced footprint, lighter weight and the placement of the vacuum connections on the top side ensures easy system integration. They are available with either a conventional radial shaft sealing ring or a magnetic coupling. Pfeiffer Vacuum Inc.
