4.2.3.2 Two-stage rotary vane vacuum pumps. Two-stage rotary vane pumps are suitable for applications in the low and medium vacuum ranges down to a pressure of 10-3 hPa. An integrated gas ballast feed allows condensable vapors to be pumped down.
Two-stage rotary vane pumps can be used in the pressure range between 100 hPa and a pressure roughly a decade above the final pressure. Pumps belonging to the DuoLine series cover a pumping speed range of 1.3 to 300 m 3 /h. In the 5 21 m 3 /h range, Pfeiffer Vacuum also offers the Pascal series as products with superior vacuum performance.
Two Stage vacuum pumps are the workhorse of the vacuum industry, with a wide variety of applications across the board. Our two stage oil-filled rotary vane vacuum pumps use plates or vanes, in an offset rotor to compress gas to the pump exhaust.
