Choosing The Right Nozzle For The Job

  1. 1. Choosing The Right Nozzle For The Job
  2. 2. jjei.com Just like your toolbox has many different tools, there are many nozzles for different pipe conditions. Penetrating nozzles for breaking up blockages, Flush nozzles for moving debris, Finish nozzles for scouring pipe walls, Floor Cleaners for removing debris from the bottom of the pipe and many other nozzles for general and specific applications. Selecting the Proper Tool
  3. 3. jjei.com When selecting your nozzles it is important to consider your nozzles Tier design. Tier I & II nozzles with flat bottoms create water turbulence and lose energy. Tier III Fluid Mechanics smoothly redirects water flow with minimal turbulence and energy loss. Tier III nozzles have three time the power over Tier I and a greater cleaning and pulling power. Basics of Tier Design • Basic Nozzle • Disposable • Drilled Orifices • Poor Fluid Mechanics • 30% efficiency rating • Very common in the industry • Lowest purchase price • Most expensive to operate due to inefficient design • More Choices • Higher First Cost • More Durable due to replaceable Orifices • Poor/Fair Fluid Mechanics • 60% efficiency rating • Most common “upgrade” in the industry • Yet More Choices • Good/Excellent fluid mechanics • Replaceable inserts • Highest First Cost • Highest Performance • +80% efficiency rating • Most cost effective nozzle design Tier I Tier II Tier III
  4. 4. jjei.com Jet Angles Typical Jet Angle 30-35 15-20 10 Characteristics Optical Cleaning effectiveness, but low thrust Good trust, but less cleaning effectiveness Very good thrust, but low cleaning effectiveness
  5. 5. jjei.com Pipe Cleaning As A Process Complete Blockage Partial Flow Conditions Free Flow Conditions • Root mass • Grease • Silt & Debris • Pipe collapse • Obstructions • Root mass • Grease • Silt & Debris • Protruding taps • Tuberculation • Periodic cleaning • Finishing process • Monitor for future problems Possible Problems • Chain Cutters • Penetrating Family • Traction Nozzle Possible Nozzles • Specialty Rotors • Floor Cleaners • Cleaning Family • Chain Cutters • Finishing Family • Cleaning Family • Floor Cleaners Situation
  6. 6. jjei.com Chain Cutters Chain cutters have the flexibility to handle the removal of the heaviest obstructions, while being gentle on pipe walls. They are ideal for customers with root infiltration, grease, concrete, protruding taps, and scaling problems. Advantages: Easily configured for multiple jobs, high speed, high torque, rottar chain is forgiven on pipe walls
  7. 7. jjei.com Penetrating Nozzles are designed to “break up the stoppage” fast. When the toughest clogs and obstructions are encountered in a sewer line, high performance penetrating nozzles should be used for the task at hand. Deformed pipes, sand, mud, roots, trash, or other blockages inevitably yield to these high performance nozzles. Penetrating Nozzles Tier ONE: Good Thrust, Forward Jets Tier TWO: Best Thrust, Forward Jets, Drill PointTier One: Better Thrust, Drill Point
  8. 8. jjei.com Penetrating Nozzles Tier THREE: Heavy Debris removal, Gentle on Pipe Walls, Ability to Separate Water Coming Into the Nozzle and Water Coming From the Nozzle Ideal for small and medium storm drain or sewer cleaning applications where pipes are heavily exposed to debris, or where pipes are heavily damaged or weakened. The Stallion nozzle is ideal for flushing corrugated metal, concrete, clay, or plastic pipe. Ideal for larger storm drain or sewer cleaning applications where pipe walls may be compromised and pressure on the pipe wall is not desired
  9. 9. jjei.com Floor Cleaners Floor cleaners are ideal for removing sludge, mud, and other compacted materials and heavy debris (rocks, bricks, broken concrete, etc.) from storm lines, detention systems, culverts, and large sanitary lines. Advantages: Reduced operating costs , high efficiency cleaning
  10. 10. jjei.com Cleaning Nozzles Ideal for routine pipe cleaning and maintenance applications. Cleaning Nozzles come in unique sizes and shapes with a variety of jet angles, jet quantities, and jet locations. Tier ONE: Lower Efficiency, Shorter Life Span Tier TWO: Better Efficiency, Longer Life Span Tier THREE: Most Efficient & Most Powerful Fluid Mechanics, Longest Life Span
  11. 11. jjei.com Finishing Family When contractors or municipalities "finish" a pipe cleaning job, they often view streaks on the pipe walls during their video inspection. These "streaks" are actually grease residue that has not been removed by the other cleaning processes. This free spinning Rotor will remove those last grease deposits, along with tender roots and other vegetation, to "ensure perfectly cleaned pipe and a finished job", hence our finishing label. Advantages: Ease of maintenance, high efficiency cleaning
  12. 12. jjei.com Specialty Nozzles: Aqua Power 700 Nozzle By simply increasing or decreasing the pressure in the water system, the speed of rotation can be controlled by the operator. The Aqua Power 700 is an excellent all around cleaning and grease removal nozzle for pipelines, manholes and lift stations. Quick Facts: Pipe range: 6”-24”+ Flow Range: 50 GPM - 120 GPM Pressure Range: 1700 PSI – 3000 PSI Hose size: 0.75”,1”, 1.25”
  13. 13. jjei.com Specialty Nozzles: R2D2-1 Nozzle The R2D2-1 combines lightweight versatility and cleaning for low flow machines running a minimum of 12GPM and an operating pressure of 2000 PSI. It is an excellent all around cleaning and grease removal nozzle for pipelines. Quick Facts: Pipe range: 4”, 6” Flow Range: 16 GPM - 40 GPM Pressure Range: 1700 PSI – 2400 PSI Hose size: 3/8”, 3/4”
  14. 14. jjei.com Specialty Nozzles: Equalizer Nozzle The Equalizer Nozzle creates an umbrella pattern blocking airflow that creates problems blowing toilets. Six powerful rearward jets with KEG’s high efficiency patented Fluid Mechanics provide the ultimate in propulsion, cleaning and debris removal. Quick Facts: Pipe range: 6”+ Flow Range: 50 GPM-130 GPM Pressure Range: 1000 PSI – 3000 PSI Hose size: 0.75”,1”, 1.25”
  15. 15. jjei.com Specialty Nozzles: DUCE Nozzle The DUCE uses vibrating action in the pipeline to break up hard scale and deposits. It is ideal for removing grout and mortar residue, scaling, tuberculation or other deposits that have hardened to the pipe wall or floor. Quick Facts: Pipe range: 2”+ Flow Range: 5 GPM-125 GPM Pressure Range: 1300 PSI – 2000 PSI Hose size: 0.375” - 1.25”
