FAQ
Frequently asked questions
Answers about application, selection, pressure ranges and the inquiry process.
Why does DUEBRE TEC need information about my pump and hose?
To recommend the optimum nozzle for your application, we need a few technical details about your jetting unit.
This includes:
• Pump flow rate (l/min or GPM)
• Operating pressure (bar or PSI)
• High-pressure hose length
• Hose diameter
• Hose material
These parameters allow us to match the nozzle orifice size and spray pattern precisely to your system. The result is maximum cleaning performance, efficient water consumption, and minimal pressure loss.
Why isn’t high pressure alone enough for effective cleaning?
Many users focus primarily on operating pressure. However, effective pipe cleaning depends on the correct combination of pressure, water flow, and the right nozzle.
Only when these factors are properly matched can maximum cleaning performance be achieved.
How do I choose the right nozzle for my application?
Selecting the right nozzle depends on several factors, including:
• Pipe diameter
• Type of deposit or cleaning application
• Water flow
• Operating pressure
• Hose length
Simply use the filter options in our interactive product catalog to narrow down your selection.
Our sales team will also be happy to help you find the best solution for your application.
Which nozzle is best for removing roots?
Depending on the severity of the root intrusion, we recommend products such as:
• Chain flails
• Saw attachments
• Milling tools
The best solution depends on the pipe diameter and the extent of the root growth.
Suitable DUEBRE TEC products include the T-Allstar, T-Spider, and the Blue 100 equipped with either a chain flail or a saw attachment.
Which nozzle is best for removing grease deposits?
Depending on the application, suitable solutions include:
• Rotary nozzles
• Vibration nozzles
• Cleaning nozzles with optimized spray patterns
The ideal choice depends on the type and severity of the deposits.
Suitable DUEBRE TEC products include the T-Bombs, Aquadrills, Rotating Nozzles, and 360° Nozzles.
Why are different jet patterns available?
The jet pattern affects:
• Thrust
• Cleaning performance
• Surface coverage
• Nozzle propulsion
Different cleaning applications require different jet patterns to achieve the best possible results.
Why are different nozzle orifice sizes available?
The nozzle orifice size determines the water flow and directly influences pressure, thrust, and cleaning performance.
Only correctly sized nozzle inserts allow your pump to deliver its full performance.
Can I use any nozzle with any pump?
No.
Every nozzle is designed for a specific operating range in terms of pressure and water flow.
Using an incorrectly sized nozzle can reduce cleaning performance, increase wear, and may even create a safety hazard.
What are the advantages of ceramic inserts?
Ceramic inserts offer several benefits:
• Excellent wear resistance
• Consistent spray performance
• Long service life
• Reduced maintenance costs
Can DUEBRE nozzles be used with recycled water?
Many DUEBRE nozzles are suitable for use with both fresh water and recycled water.
Depending on the product and application, we will recommend the most suitable version.
When should I use a rotary nozzle?
Rotary nozzles are particularly suitable for:
• Grease deposits
• Hard encrustations
• Pipe preparation
• CCTV inspection preparation
• Pipeline rehabilitation preparation
They provide uniform 360° cleaning of the entire pipe wall.
How often should a nozzle be inspected?
Nozzles should be inspected regularly for wear.
Worn nozzle orifices can alter the spray pattern, increase water consumption, and reduce cleaning performance.
How can I tell if a nozzle is worn?
Typical signs include:
• Reduced cleaning performance
• Increased water consumption
• Uneven spray pattern
• Longer cleaning times
Does DUEBRE TEC offer custom solutions?
Yes.
In addition to our standard product range, we design and manufacture custom nozzles and tools tailored to your specific cleaning application.
