The Pfeiffer UNO 30 M 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 30-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.
