Sewer JetterMJ-3000

High-pressure jetting clears a blocked line and flushes the debris out of it, rather than just pushing the blockage further down the pipe. The MJ-3000's 153 LPM / 130 bar triplex plunger pump, driven by a full-torque split-shaft PTO off the vehicle's gearbox, forces water through a 3/4" x 60m hose and a self-propelled nozzle that pulls itself forward through the line, breaking up the blockage and flushing debris ahead of it. Because it maintains constant pressure at the nozzle regardless of hose length, it cleans faster and more consistently than mechanical rodding or cable machines, and its higher flow moves larger volumes of debris than the smaller MJ-series units. A hydraulically wound hose reel and an additional hand-held washing gun for equipment, vehicle, and general high-pressure washing round out the unit.

Every MJ-series sewer jetter ships standard with two nozzle types:

• Conical Head Nozzle (front and rear holes) — a general-purpose nozzle that balances forward penetration with rear thrust to pull the hose through the line
• Round Head Nozzle (front and rear holes) — a wider spray pattern for flushing loosened debris out of the line

Additional nozzle types can be supplied to match specific jetting jobs, including:

• Penetrator Nozzle — forward and rear jets to punch through grease plugs and tough blockages before flushing
• Root Cutter Nozzle — carries small cutting blades driven by the water jets to shred root intrusions
• Flusher / Descaling Nozzle — flailing chains or carbide tips to scour hardened scale and mineral buildup from pipe walls
• Rotating Nozzle — spins under pressure for 360° wall cleaning, effective on grease and light debris

• Sewer and drain lines from about 450 to 500mm (18-20 inches) in diameter
• Municipal trunk lines and larger commercial jobs beyond the MJ-1000's capacity
• Crews that want a hose counter to track footage fed into the line
