DUEBRE Bulldozer – Maximum cleaning power where it’s needed most.

For more than 40 years, DUEBRE BULLDOZER Invert Cleaning Nozzles have set the standard for efficient sewer cleaning. Specifically designed for pipelines DN 300 (12″) and larger, they concentrate the entire available water flow directly onto the invert of the pipe, delivering exceptional cleaning performance while using water as efficiently as possible.

Designed for Heavy Deposits

Whether dealing with sand, sludge, gravel, or stones, BULLDOZER Invert Cleaning Nozzles are engineered to remove heavy deposits from the bottom of the pipe. Their robust design and precisely directed water flow generate outstanding flushing and transport performance without wasting valuable water.

Even in pipelines with a high water level, BULLDOZER nozzles perform reliably. Their substantial weight keeps them firmly on the pipe invert, preventing the nozzle from floating during operation. A durable wear-resistant edge protection also ensures excellent sliding characteristics during both forward and reverse travel.

Efficient, Durable, and Customized

BULLDOZER nozzles combine high cleaning performance with low water consumption, making them an excellent choice for vehicles equipped with water recycling systems.

For maximum service life, every nozzle comes standard with replaceable hardened steel skids. The nozzle inserts are fitted with ceramic orifices mounted in stainless steel, providing outstanding wear resistance and long-lasting performance. Additional configurations are available upon request.

To achieve the best possible cleaning results, every BULLDOZER nozzle is individually matched to the customer’s jetting unit. We simply require the following information:

Pump flow rate (l/min or GPM)
Operating pressure (bar or PSI)
High-pressure hose length
Hose diameter
Hose material

This ensures that the nozzle orifices and spray pattern are precisely optimized for your equipment.

Recommended Setup

For optimum handling and maneuverability, we recommend using a swivel in combination with BULLDOZER Invert Cleaning Nozzles.

With their rugged construction, concentrated water delivery, and exceptional debris removal capability, DUEBRE BULLDOZER Invert Cleaning Nozzles have been a trusted solution for demanding sewer cleaning applications for decades.

Lower water consumption, maximum cleaning performance, and long-lasting durability make them the preferred choice for removing heavy deposits in municipal and industrial sewer systems.
