Retrofitting old hydrants - without excavation work
The Hawle revision cartridge makes it possible: Old hydrants, born 1935 or later, receive a second life.
Conversion under full network pressure
The old hydrant mechanism is replaced under full mains pressure. The complete mechanics are replaced and the hydrant is converted to the radial sealing system and fine adjustment.
The cartridge is inserted into the old hydrant housing and clamped onto the old valve seat with great force. Thus the old seat is put out of operation. The pressure water protection prevents unwanted water losses due to emptying during opening and closing.
Experience in demand
Installation under full mains pressure requires a lot of experience. These are offered by our competent service technicians.
We will be pleased to make you an offer for the conversion of your hydrants.
