Pfeiffer Vacuum

The UNO 30M rotary vane pump has magnetic coupling to maximize uptime pumping speed of 35 m3/h (1,235 ft3/h) at 60 Hz, and comes standard with a single-phase motor for easy electrical connection. The magnetic coupling eliminates radial shaft seals, increasing pump life and making pump repairs easier if service is necessary. The pumps are hermetically sealed resulting in negligible leak rate of <1E-5 mbar 1/sec. The vacuum process is protected by an integrated hydraulically controlled, high-speed, high-vacuum safety valve.
