Pfeiffer Vacuum’s two-stage DuoLine rotary vane pumps are distinguished by an optimised pump system and cooling. The changes have a significant impact on the service lives of the pumps. The long maintenance intervals, the energy-efficient motors and the optional oil return lower the operating costs to a very low level.
The integrated, hydraulically controlled high-vac-uum safety valve increases operational reliability. The reduced footprint, lighter weight and placement of the vacuum connections on its top side guarantee the pumps‘ easy system integration.
The DuoLine pumps are offered with a conventional radial shaft sealing ring or with a magnetic coupling. The special drive concept hermetically seals the magnetically coupled rotary vane pumps. The operating costs of the magnetically coupled pump are low, as it is virtually maintenance-free.
