<p>The present invention relates to a flushing apparatus for internally cleaning a piping system. The object of the invention is to achieve efficient cleaning without requiring the use of equipment which is substantially larger than that required for the nominal flow through the piping system. According to the invention, there is provided a pump having an operational pressure essentially higher than the pressure drop of the piping system at a turbulent flow, in combination with at least one pressure liquid accumulator. The flushing circuit includes at least one blocking valve which is opened upon reaching the intended (maximal) pressure, thereby producing a powerful flow pulse through the piping system.</p> |
