Dongfeng D6 Combined High‑Pressure Washing & Sewage Suction Truck

We build this Dongfeng D6 combined high‑pressure washing & sewage suction truck on the proven Dongfeng second‑class chassis EQ1045SJ3CDF. It runs with a 3308 mm wheelbase and 7.00R16 steel radial tires. Furthermore, its 114 kW engine complies with Euro‑VI emission rules. It delivers solid performance, convenient after‑sales support and comfortable driving experience.

In addition, the dual‑tank system holds a 2 m³ freshwater tank and a 4 m³ sewage tank, and these two tanks can interconnect. We use 3.5 mm steel plates for the freshwater tank and thicker 5 mm steel plates for the sewage tank. Besides, we fit hose‑laying platforms on both tank sides. This truck carries a Pinfu 215L high‑pressure water pump, which delivers 215L flow rate at 24 bar working pressure. It can clear municipal pipelines that range from 300 mm to 600 mm in diameter. Meanwhile, its SK‑9 water‑ring vacuum pump reaches 1800 m³/h air flow and offers 6‑8 meters vertical suction depth for sewage‑removal jobs.

For cold‑climate regions, you can select the air‑blow‑off function. This feature clears leftover water inside high‑pressure hoses and pump units, so it prevents freeze‑caused cracks during wintertime. Moreover, double‑top oil cylinders with buffer support rods sit below the tanks. They make tank lifting and lowering safer and keep the whole vehicle stable during operation. Specifically, you get a ball‑valve‑style fire‑hydrant water inlet, reinforced liquid‑level gauge and bayonet manual valve as standard parts.

Lastly, our standard package includes a tool box, DN100 ball‑valve suction port, DN150 ball‑valve discharge outlet, valve force‑boost lever, and hydraulic rear cover with locking mechanism. You will receive 60‑meter Φ19 high‑pressure hose,10‑meter PVC102 mm vacuum suction hose, one 1.5 kg water‑jet nozzle plus one straight nozzle.

All in all, this all‑in‑one truck handles municipal sewer dredging, septic‑tank cleaning, sludge collection and waste‑water disposal for urban sanitation projects.
