KEY INFORMATION
Nozzles with a special body balance, always position themselves in such a way that all the energy of the outlet jets is directed to the bottom of the sewer. The nozzle is extremely effective and has a high attack force. In the design of the nozzle an off-centre hose connection was used. We recommend to use the nozzle with a rotary joint. The nozzle acts as a BULLDOZER, it rinses out heavy sand and gravel deposits, also in highly silted pipes.
An innovative solution is the introduction of the forward water jet, located in the lower part of the nozzle, which defines the nozzle's advance path and allows it to penetrate under debris. The nozzle is manufactured of heat-treated alloy steel which increases its abrasion resistance and ensures a long service life. It is is offered in 3 sizes.
ADVANTAGES

- the nozzle available in the models: DD-120, DD-150, DD-200
- abrasion resistance due to the use of high-alloy heat treated steel
- every nozzle is customised according to the parameters of the Customer’s pump
