Introduction
enz® HRV nozzles with four 45° jets impacting forward onto the pipe wall, a front jet
(if requested) and three rear thrust jets work like a corkscrew to penetrate a clogged
pipe. As a result, the deposits are broken up, removed by the semi-
radial nozzle’s rotor
and pushed forward. The thrust jets produce the forward motion.
Application range
•
Flushing out steel pipes after pipe-jacking
•
Flushing of the pipes from the building toward the main line
•
Removal of ice in manholes and pipes
