Simple, Robust and Suitable for the Entire Pressure Range

Simple, Robust and Suitable for the Entire Pressure Range [Pg.52]

LRVPs in closed coupled design with variable pressure ports for covering the entire pressure ranging from approximately 40 to 1013 mbar represent at present the most frequently used design with new installations due to their good price-performance ratio. But even these vacuum pumps do not meet all the requirements. Thus, deposits in the dead spaces and drUHngs as well as defects of the valves ofthe variable pressure ports rank among the most frequent causes of failure. [Pg.52]

Investigations of vacuum pumps with fluidic optimised working openings and free of dead space have shown that the named pressure range can also be covered without variable pressure slots. [Pg.52]
