ISUZU 8000L Combined Jetting Vacuum Truck
The ISUZU 8000L Combined Jetting Vacuum Truck is a heavy-duty sewer cleaning vehicle designed to perform both high-pressure sewer jetting and vacuum suction operations with one integrated system, making it suitable for municipal sewer maintenance, drainage pipeline cleaning, septic waste removal, sludge collection, and industrial wastewater management. By combining a large-capacity sludge tank, clean-water tank, powerful vacuum pump, and high-pressure jetting pump on a robust ISUZU FTR chassis, the truck can clean blocked pipelines and simultaneously recover sewage and debris, significantly improving the efficiency of professional sewer maintenance operations.
The truck has overall dimensions of 7,500×2,500×3,650mm, a gross vehicle weight of approximately 18,000kg, and a 4,500mm wheelbase, while the 6.5-ton front axle and 11.5-ton rear axle provide a strong foundation for the heavy-duty combination equipment. Six working tires plus one spare tire, using 10.00R20 specifications, provide suitable support for demanding municipal and industrial applications.
Power comes from an ISUZU 4HK1-TC50 diesel engine producing approximately 205HP and meeting the Euro 5 emission standard, while the ISUZU MLD-6Q manual transmission provides six forward gears and one reverse gear. The ISUZU FTR flat-roof short cab features left-hand drive and seating for three passengers, providing a practical working environment for the driver and sanitation crew.
The combined tank has a total internal volume of 8,000 liters, divided into a 5,000-liter sludge/sewage compartment and a 3,000-liter clean-water compartment. Manufactured from 6mm Q235 mild steel, the tank is designed to withstand the vacuum and pressure conditions associated with combined sewer cleaning operations, while a rear-tipping arrangement and fully openable rear door facilitate convenient sludge discharge and tank maintenance.
For vacuum recovery, the truck is equipped with a JUROP LC750 vacuum pump offering an air capacity of approximately 1,200m³/h and a maximum vacuum level of 95%. For pipeline cleaning, a Pratissoli MX45 high-pressure jetting pump from Italy delivers up to 269L/min at a maximum pressure of 200 bar, providing strong water-jetting performance for removing sludge, grease, sediment, and blockages from sewer pipelines.
Features
1. Heavy-Duty ISUZU FTR Chassis
The ISUZU FTR chassis provides a strong and reliable platform for the combined sewer cleaning system, with a gross vehicle weight of approximately 18,000kg and a 4,500mm wheelbase that helps support the substantial tank and pumping equipment.
The 6.5-ton front axle and 11.5-ton rear axle are matched with 10.00R20 tires, configured with six working tires plus one spare, providing suitable load-bearing capability and durability for municipal roads, industrial facilities, construction areas, and sewer maintenance sites.
2. Powerful 205HP ISUZU Diesel Engine
The vehicle is equipped with an ISUZU 4HK1-TC50 diesel engine delivering approximately 205HP and complying with Euro 5 emission requirements. The engine provides sufficient power for both road transportation and operation of the truck’s specialized sewer-cleaning equipment.
The ISUZU MLD-6Q manual transmission offers 6 forward gears and 1 reverse gear, allowing the driver to select suitable gear ratios according to road conditions and vehicle load while maintaining practical operating efficiency.
3. Dual-Compartment 8,000L Tank
The truck features an 8,000-liter combined tank divided into two independent compartments, consisting of a 5,000-liter sludge/sewage tank and a 3,000-liter clean-water tank.
This configuration allows the truck to carry clean water for high-pressure sewer jetting while simultaneously providing substantial capacity for collecting sewage, sludge, and debris through the vacuum system, eliminating the need for separate jetting and vacuum vehicles in many sewer maintenance operations.
4. Strong Q235 Steel Tank Construction
The tank is manufactured from 6mm Q235 mild steel, providing the structural strength required for repeated vacuum and pressure operations. The tank is designed to withstand the operating conditions created by the vacuum pump, jetting system, liquid weight, and transportation.
The tank is also hydrostatically tested to verify its structural integrity, while the rear section incorporates reinforcement and a robust opening system for maintenance and unloading.
5. Efficient JUROP LC750 Vacuum Pump
The vacuum system uses a JUROP LC750 vacuum pump featuring an air capacity of approximately 1,200m³/h and a rotor speed of around 1,200rpm, with a maximum vacuum level of approximately 95%.
The pump uses a water-cooled compressor and vane-pump configuration with automatic lubrication, copper oil piping, and an integrated vacuum-pressure changeover valve. Its heavy-duty drive arrangement is designed to provide reliable suction performance during continuous sewage and sludge collection.
6. Italian Pratissoli High-Pressure Jetting Pump
For sewer pipeline cleaning, the truck is equipped with a Pratissoli MX45 high-pressure jetting pump manufactured in Italy. The heavy-duty positive-displacement triplex reciprocating pump can deliver a maximum flow of approximately 269L/min at a pressure of up to 200 bar.
This high-pressure water flow can be used to break up accumulated sludge, grease, sediment, and other deposits inside sewer pipelines, helping restore drainage capacity while the vacuum system simultaneously recovers the loosened material.
7. Integrated Jetting and Vacuum Operation
The key advantage of this Combined Jetting Vacuum Truck is that high-pressure water jetting and vacuum recovery can be performed as part of the same sewer-cleaning operation.
The jetting system loosens and flushes accumulated material from the pipeline, while the vacuum system collects sewage, sludge, and debris into the dedicated 5,000-liter waste compartment. This integrated workflow can reduce equipment requirements, minimize repeated site visits, and improve overall sewer maintenance productivity.
8. Rear-Tipping Tank and Fully Openable Rear Door
The tank is mounted with a rear-tipping arrangement, allowing collected sludge and sewage to be discharged more efficiently at an approved disposal or treatment location.
The rear door is designed to open to approximately 80° from the vertical and uses handwheel-operated bolts and manual latches for secure sealing. A self-compensating seal helps prevent leakage during transportation, while the fully openable configuration also provides better access for tank inspection, cleaning, and maintenance.
9. Multi-Level Safety Protection
The vacuum and pressure systems incorporate several safety devices to protect the equipment and operators during operation. A primary ball-float shut-off helps prevent liquid from accidentally entering the vacuum pumping system if the tank becomes overfilled.
A secondary shut-off system provides additional overflow protection, while vacuum relief and pressure relief valves help maintain safe operating conditions when the internal tank pressure reaches predetermined limits. The high-pressure jetting system also incorporates pressure relief valves, unloading valves, water filters, and pneumatically actuated three-way valves.
10. Practical Tank Monitoring and Maintenance Design
The tank is equipped with transparent acrylic level indicators, with one indicator provided for each compartment, allowing operators to monitor the approximate liquid level in both the sludge/sewage and clean-water sections.
A tempered sight glass is also installed at the tank end to help measure the sewage volume inside the tank, while the sight glass is designed for convenient replacement. Access ladders are provided on the tank to facilitate inspection and maintenance of the upper equipment.
11. Integrated Hydraulic and Control System
The truck uses a combination of high-pressure pipes and flexible hydraulic hoses for its hydraulic connections, making component replacement and maintenance more convenient when necessary.
The truck and specialized sewer-cleaning unit are equipped with the necessary controls, gauges, and safety devices to allow the operator to monitor and manage vacuum suction, high-pressure jetting, tank functions, and other working systems from the operating controls, providing a practical configuration for professional sewer maintenance crews.
