 Isuzu Combined Vacuum High Pressure Jetting Tanker Truck 14KL Sewage+4KL Clean Water

Isuzu Combined Vacuum High Pressure Jetting Drainage Cleaning Truck | 14m³ Sewage + 4m³ Clean Water Integrated Sewer Jetter Vacuum Tanker
 Isuzu GIGA Chassis Truck Mounted High Pressure Water Jetter System for Municipal Sewer, Drainage & Culvert Maintenance

Product Overview

The Isuzu drainage cleaning truck is a heavy-duty, all-in-one sanitation vehicle engineered exclusively for urban sewer network maintenance, drain unclogging, culvert dredging and wastewater treatment. Built on reliable Isuzu GIGA 6×4 heavy-duty chassis, this combined sewer jet vacuum tanker integrates high-pressure water jet flushing and powerful sewage vacuum suction functions in one unit, eliminating separate flushing and suction vehicles to cut municipal operation costs drastically.
Powered by the robust Isuzu 6UZ1-TCG 380HP industrial diesel engine meeting Euro  5/6 emission standards, the truck delivers stable torque, strong climbing capacity and long-distance driving reliability. Perfectly suited for sanitation bureaus, municipal engineering departments, property management groups and environmental service companies, it effortlessly tackles clogged storm drains, underground sewer pipelines, sediment-filled culverts and septic tank sludge cleaning with outstanding efficiency.

Core Product Advantages & Features

1. High-Pressure Water Jetting Flushing System

The truck adopts an adjustable full-automatic high-pressure jetter system as its core flushing module. Operators freely adjust water pressure and flow rate to match pipeline blockage conditions. High-speed pressurized water blasts mud, tree roots, gravel, grease and hard sediment adhered to pipe inner walls, thoroughly breaking up stubborn clogs without damaging sewer pipelines. Fast flushing greatly shortens on-site construction downtime and boosts daily cleaning throughput.

2. Heavy-Duty Integrated Vacuum Suction System

Equipped with either top-tier Chinese dual vacuum pumps or imported Italy/Spain original vacuum pumps as optional upgrades, the suction unit reaches a theoretical vacuum rate of 99% with low noise and high rotation efficiency (500rpm). The 6–8m extended suction hose rapidly extracts broken sludge, sewage and floating waste cleared by the jetting system, achieving one-stop dredging and waste collection.
  • Hydraulic tipping tank design: Tank lifts over 45° for convenient sludge discharge

  • Hydraulic automatic opening/closing rear tank door for easy waste unloading

3. Complete Intelligent Safety Protection

  • Overfill alarm system with music horn: Automatically alerts operators when the sewage tank reaches full capacity, preventing sewage backflow and vacuum pump damage

  • Multi-stage separation devices: Built-in water-gas separator and oil-gas separator to filter impurities and extend pump service life

  • Ergonomic Isuzu GIGA flat roof cabin: 2 seats + 1 rest bed, panoramic wide vision, anti-slip floor and safety handrails to protect operators during on-site work

  • Standard driving recorder, central locking, power windows and air conditioning for long-shift driving comfort

4. Durable Corrosion-Resistant Tank Body

The sewage and clean water tank body is constructed with 5mm/6mm thick high-strength carbon steel as standard. Stainless steel tank lining and internal anti-rust coating are available as optional upgrades to resist long-term corrosion from acidic, alkaline sewage sludge. Custom tank exterior paint colors are supported to match client corporate or municipal uniform standards.

5. Full Standard Configuration & Customizable Optional Parts

Standard Factory Configurations

  1. 400L large-capacity fuel tank for long continuous operation

  2. Full hydraulic PTO drive system (engine power take-off to drive vacuum pump & jet pump)

  3. Multi-way hydraulic control valve, real-time pressure monitoring gauges

  4. Independent hydraulic oil tank, inspection observation window, hand washing tank

  5. 6m wear-resistant suction hose, side maintenance climbing ladder

  6. Tubeless tires, reflective safety markings, maintenance-free battery, power steering

Upgradable Optional Equipment

  • Imported Italian/Spanish high-efficiency vacuum pumps

  • Full stainless steel tank body

  • Internal tank anti-corrosion epoxy coating

  • Auxiliary independent diesel engine to drive pump units (no chassis engine power consumption)

What Is a Truck Mounted Jetter System?

The truck-mounted jetter system is the core flushing assembly integrated on the Isuzu drainage cleaning truck, consisting of high-pressure water pumps, control valves, retractable jet hoses and power transmission parts. Different from separate trailer jetters, this integrated design shares the truck chassis power via PTO, requiring no additional transport vehicles. It realizes flexible on-site mobile sewer cleaning, ideal for narrow urban roads, residential community pipelines and remote rural drainage networks. Combined with the matched vacuum suction tank, it forms a dual-function jet-vac all-in-one sanitation vehicle to finish pipeline dredging and waste collection in a single trip.

Application Scenarios

  • Municipal city sewer pipeline dredging & blockage removal

  • Stormwater drain, underground culvert, flood discharge channel cleaning

  • Septic tank, grease trap, sewage sediment tank sludge suction & transportation

  • Highway roadside drainage ditch maintenance

  • Industrial park wastewater pipeline desilting
