Abstract

Illustrated and described are a method and a device for the simultaneous cleaning of a plurality of pipe conduits or pipe conduit systems, particularly in each case having different pipe cross sections, wherein the cleaning takes place with a liquid cleaning medium, which is taken from a reservoir by a feed pump and fed to the systems to be cleaned. The invention makes provision for the cleaning medium stream to be fed to the first system to be cleaned and after leaving the first system to be cleaned, as cleaning medium stream, to be divided into two component streams, one component stream of which is used for cleaning the second or further system and the other component stream is again fed to the reservoir. In addition the second or further system to be cleaned is assigned a feed pump, whose speed and direction of rotation are variable for determining or regulating the cleaning method.
