- Dual-Stage High Performance Rotary Vane Pump
- Motor Incorporates Diverse Voltage Settings
- Included Gas Ballast & Safety Valve
- Optional Feature for Magnetic Coupling
The Pfeiffer UNO 6M Vacuum Pump is a direct replacement and update over the now-obsolete Pfeiffer UNO 2.5 Vacuum Pump. The UNO 6M series of Pfeiffer Rotary Vane vacuum pumps incorporates oil-stage lubrication and a two-stage operating mechanism.
Our Pfeiffer UNO 6-M vacuum pumps are likewise equipped with a high vacuum safety valve. This valve mechanism tightly seals the vacuum chamber while the pump is operating at standstill mode, while simultaneously allowing for ventillation of the pump.
Power cable is not included.
