Skid/Wheeled Packers
These packers are made of a rubber sleeve that is vulcanised onto metal heads. The interior tube lets the water flow off during the repair work. The open safety coupling with a lock pin prevents unwanted decoupling. The flexible construction means it is easy to conduct the packer through a manhole and install it in the damaged line.
The carriage has a slight spring action and can be flexibly adjusted to tatch the pipe diameter. On top of that, the runner-shaped carriage facilitates smooth sliding, even over offsets. The wheels are ser at a 120 angle, which ensures easy packer penetration.
