The CHENGLONG H7 14CBM High Pressure Vacuum Truck is a powerful, dual-function sanitation vehicle designed for heavy-duty sewer cleaning, sludge removal, and pipeline maintenance in municipal, industrial, and oilfield applications. Built on the robust DONGFENG CHENGLONG H7 6×4 chassis with right-hand drive, it is powered by the high-torque YC6MK385-50 diesel engine, delivering 385 horsepower to support demanding simultaneous operation of vacuum and high-pressure water systems.
The superstructure integrates two durable tanks made of 6mm-thick carbon steel: a 10,000-liter (10CBM) sewage tank equipped with a high-efficiency SK-42 vacuum pump for rapid suction of sludge, wastewater, and solids; and a 4,000-liter (4CBM) freshwater tank paired with a PINFL XV40 high-pressure pump that delivers 330 liters per minute at ultra-high pressure—ideal for breaking up blockages, flushing pipelines, and cleaning manholes or storm drains.
This combination enables versatile, one-stop operation: jetting to loosen debris immediately by vacuum extraction, significantly boosting work efficiency. The truck features reinforced tank supports, anti-corrosion treatment, safety overflow valves, and operator-friendly controls suitable for continuous field use.
Designed for professional sanitation fleets, the CHENGLONG H7 14CBM High Pressure Vacuum Truck merges exceptional power, large-capacity fluid handling, and rugged construction into a single platform—making it an ideal solution for cities, refineries, airports, and infrastructure projects requiring reliable, high-performance environmental cleaning under tough conditions.
