Features of ISUZU 6 CBM Sewage Suction & Cleaning Truck

1. Heavy-Duty ISUZU Chassis for Sanitation Operations

The truck is built on a heavy-duty ISUZU chassis engineered to support the weight and working requirements of a 6,000-liter sewage suction body and its associated vacuum equipment. With a 3,800 mm wheelbase, the chassis provides a useful balance between vehicle stability and maneuverability, while the overall dimensions of 8,200 × 2,500 × 3,200 mm provide sufficient space for the sewage tank, vacuum system, piping, hydraulic equipment, and supporting components.

The specified curb weight is 9,450 kg, with front and rear axle loading capacities of 6,300 kg and 13,000 kg respectively, giving the vehicle a substantial chassis configuration for regular wastewater transportation. The 10.00R20 tires, with six tires plus one spare, are also suited to the vehicle’s operating requirements and provide a practical configuration for municipal and industrial road applications.

2. 120 HP Chaochai Diesel Engine

The truck is powered by a Chaochai CY4102 diesel engine with a 5,193 ml displacement, four-cylinder configuration, 88 kW maximum power, and 120 HP output. The diesel powertrain provides the basic driving performance required to transport a fully loaded sewage tank between collection locations and disposal or treatment facilities.

The engine is matched with a manual six-speed transmission offering six forward gears and one reverse gear, allowing the driver to select suitable gearing for urban roads, highways, industrial areas, and working locations with different operating conditions. A reinforced diaphragm clutch is also fitted to support the regular load and stop-start requirements associated with municipal sanitation operations.

3. 6,000-Liter Q235 Carbon Steel Sewage Tank

The main working body is a 6 CBM sewage tank with a nominal capacity of 6,000 liters, manufactured from Q235 carbon steel with a 6 mm thickness. The relatively substantial tank construction is designed to withstand the repeated loading, transportation, and discharge cycles encountered in professional sewage collection operations.

A 6,000-liter capacity makes this truck particularly practical for medium-scale sewage cleaning tasks, allowing operators to collect a significant quantity of wastewater or sludge before returning to a treatment or disposal facility. This can help reduce unnecessary trips during daily operations, particularly when the vehicle is working across residential communities, commercial facilities, industrial areas, and municipal sanitation networks.

4. High-Vacuum Suction System

The core of the vehicle’s working capability is its vacuum sewage suction system, which uses a dedicated vacuum pump with a stated absolute working pressure of 400 Pa and a vacuum degree of up to 99.6%. The pump provides a suction speed of 45 L/s and operates at approximately 500 rpm, providing the vacuum force required to draw sewage, wastewater, sludge, and other compatible liquid or semi-liquid waste materials into the tank.

This configuration allows the truck to perform suction operations at locations where conventional manual removal would be inefficient or impractical. By using vacuum pressure to transfer waste through the suction pipe, operators can carry out sewage collection with considerably less direct handling of the material, making the vehicle suitable for professional sanitation and wastewater service operations.

5. 108 mm × 5 m Suction and Discharge Pipe

The vehicle is equipped with one inlet and outlet pipe measuring 108 mm in diameter and 5 meters in length, providing a practical working reach for connecting the truck to septic tanks, sewage pits, drainage points, and other collection locations. The pipe diameter is designed to support the movement of wastewater and sludge into the tank while maintaining compatibility with the vacuum system’s working capacity.

The 5-meter length provides useful flexibility when positioning the truck near a sewage collection point, reducing the need for the vehicle to be placed directly beside every access opening. This is particularly useful in urban sanitation work, industrial facilities, residential areas, and other locations where access can be restricted by buildings, roads, fences, or other infrastructure.

6. Water-Gas and Oil-Gas Separation System

To support stable vacuum operation, the sewage suction system incorporates both a water-gas separator and oil-gas separator. These components help manage the different materials and vapors encountered during sewage suction, supporting the vacuum system and reducing the risk of unwanted liquid or oil contamination reaching sensitive components.

The system also includes a four-way valve, safety valve, anti-overflow valve, and anti-overflow warning device, creating a more complete working arrangement around the vacuum tank. These components are particularly important in sewage suction applications because operators must control both the vacuum process and the amount of material entering the tank during filling.

7. Anti-Overflow Protection and Safety Configuration

The anti-overflow valve and anti-overflow warning device provide additional protection during sewage suction operations by helping operators monitor the tank filling process and reduce the risk of excessive filling. This is an important consideration when collecting wastewater and sludge because uncontrolled overflow can contaminate the vehicle, working area, and surrounding environment.

The truck also features a safety valve as part of the vacuum system, while the chassis uses a dual-circuit compressed-air service braking system. The parking and emergency brake uses spring energy with compressed-air operation on the rear wheels, and an engine exhaust valve brake is provided as an auxiliary braking system, creating a multi-level braking arrangement appropriate for the vehicle’s operating weight.

8. Hydraulic Rear Cover and Tipping Sewage Tank

After the tank has been filled and the truck reaches the designated sewage treatment or disposal location, the hydraulic control rear cover and tipping sewage tank body provide a practical discharge solution. Hydraulic control helps simplify the operation of the rear working components, while the tipping tank body allows collected sewage and sludge to be discharged more efficiently.

This arrangement is especially useful for sanitation contractors and wastewater service providers who perform repeated collection cycles during the same working day, because efficient unloading is an important part of overall productivity. Once the tank has been emptied and the working equipment has been properly reset, the vehicle can return to the next collection point and begin another suction operation.

9. Comfortable Three-Person Air-Conditioned Cab

The cab can accommodate three people and is equipped with air conditioning, providing a practical working environment for the driver and sanitation crew. This is particularly useful for operators who spend extended periods traveling between sewage collection locations, treatment facilities, and maintenance areas.

The hydraulic power-assisted steering system also reduces steering effort and provides better control during low-speed maneuvering, while the 26° approach angle and 20° departure angle contribute to practical accessibility when the vehicle enters or exits different working areas.

10. Practical Solution for Municipal and Industrial Sewage Cleaning

The ISUZU 6 CBM Sewage Suction & Cleaning Truck is designed as a complete working vehicle rather than simply a tank mounted on a truck chassis. Its 6,000-liter Q235 carbon steel tank, high-vacuum suction pump, 45 L/s suction speed, 108 mm × 5 m suction pipe, separation system, anti-overflow protection, hydraulic rear cover, and tipping tank body work together to provide a practical solution for professional sewage collection and transportation.
