enz® nozzles with forward impact angle of approx. 45° on the pipe wall as well as a front jet (on request) and 3 retro-thrust jets cause a cork-screw-like advance through the clogged pipe. While the front nozzles loosens and the semi-radial nozzles disintegrate the residues, the thrust nozzles are driving the nozzle head forwards and simultaneously pushing the waste material backwards.

Applications

• Core-flushing of the steel pipes during hydraulic thrust-boring
• Cleaning of house connecting pipework from inside to the drain system
• Removal of ice in manholes
