Dongfeng Duolika D6 vacuum sewer suction truck
Dongfeng Duolika D6 4,000L Vacuum Sewer Suction Truck
The Dongfeng Duolika D6 vacuum sewer suction truck is designed for septic tank cleaning, sewer maintenance, sludge transportation, and industrial wastewater collection. Featuring a 4.0 m³ vacuum tank, an efficient vacuum suction system, and a hydraulic dumping mechanism, the vehicle provides a practical solution for municipal sanitation companies, property management contractors, and utility service providers.
High-Efficiency Vacuum Suction Performance
Equipped with a high-performance SK-9 water-ring vacuum pump, the truck achieves a vacuum degree of up to -0.092 MPa with an airflow capacity of 9 m³ per minute. It can draw liquid waste from depths of over 7 meters and transfer sewage over distances of up to 50 meters, allowing efficient operation in a wide variety of cleaning applications.
Durable Tank and Hydraulic Discharge System
The 4.0 m³ tank is manufactured from heavy-duty Q235-B carbon steel with reinforced anti-surge baffles to improve stability during transportation. A full hydraulic rear door and hydraulic tipping system enable rapid unloading with minimal residue, helping reduce cleaning time while improving overall operating efficiency.
Reliable Vacuum and Hydraulic Controls
The PTO-driven vacuum and hydraulic systems provide stable and dependable performance throughout suction, transportation, and discharge operations. Standard equipment, including an automatic overflow protection valve, moisture separator, oil-water separator, and centralized pneumatic controls, enhances operational safety while simplifying daily use.
Compact and Dependable Chassis
Built on the Dongfeng Duolika D6 sanitation chassis, the vehicle is powered by a Euro III diesel engine matched with a 6-speed manual transmission for reliable performance in urban and rural operating environments. The compact wheelbase and tight turning radius improve maneuverability when working in residential areas, narrow streets, and construction sites.
Designed for Daily Municipal Service
The truck is supplied with an 8-meter heavy-duty suction hose, quick-connect pipeline system, liquid level indicator, and complete safety protection devices for convenient daily operation. Optional equipment, including a rotary vane vacuum pump, stainless steel tank lining, extended suction hose, and remote hydraulic control, allows the vehicle to meet a wide range of operating requirements in different markets.
