The Dongfeng 8000L 4x2 industrial vacuum truck is designed to collect and transfer sludge, fecal matter, crude oil and other liquid waste in municipal sanitation and industrial cleanup operations. Its vacuum pump system and reinforced tank are intended to reduce secondary pollution and support efficient on-site removal, according to the product specifications.

Core technical features

The truck uses a high-capacity vacuum pump to create negative pressure inside the tank, drawing sediment, wastewater, bricks, stones and similar deposits from sewers into the vessel. A hydraulic system then supports controlled discharge of the collected material.

Compared with conventional fecal suction trucks, the industrial-grade model is specified with higher vacuum levels, a larger payload and a broader range of applications. The system is configured for long-distance suction work and heavy-duty collection duties.

Structural and selection advantages

The tank is built from 6 mm steel, with pressed heads designed to resist deformation under vacuum. The rear cover can be fully opened and is operated hydraulically, a feature intended to speed discharge and simplify cleaning.

The vehicle integrates a power take-off, drive shaft, vacuum pump, pressure gauge, hand-wash fixture and anti-overflow system. When the tank reaches capacity, an audible musical alarm warns the operator; halting suction at that point helps prevent wastewater from entering the vacuum pump.

Chassis and customization options

The range can be adapted to several chassis brands beyond Dongfeng, including ISUZU, SINOTRUCK, JAC, SHACMAN, FOTON and FAW. Tank capacities from 5,000 L to 20,000 L are available to match different municipal and industrial workloads.

Operational role and safety systems

The vehicle is positioned for routine sewer cleaning, septic waste transfer and industrial liquid removal. Its hydraulic self-dumping mechanism, with a 40- to 45-degree tilt, allows collected solids and liquids to be discharged at treatment or disposal sites.

The vacuum pump can be driven by the truck’s hydraulic motor or by an auxiliary engine, depending on the configuration and the demands of the operating environment.
