Abstract (en)
[origin: WO2006067032A1] The invention relates to a method for cleaning a dry, compressed vacuum screw-type pump comprising an inner compression. The cleaning method consists of the following steps: the screw-type pump (12) is driven at a nominal speed, a cleaning fluid consisting of rinsing fluid and a rinsing gas is mixed in a volume ratio of at least 1:10, and the cleaning fluid is introduced into the gas inlet (16) of the screw-type pump (12). According to the cleaning method, a dry, compressed vacuum-screw-type pump comprising an inner compression can be regularly cleaned in a simple manner.
