Sewage Suction Truck

Working Principle Vehicle engine drives vacuum pump via power‑take‑off, evacuating air from sealed tank to build negative‑pressure environment. Under external atmospheric pressure, sludge and sewage are drawn into tank through suction hose. Once filled, the pump switches to positive‑pressure mode for waste expulsion. The tank can also be tilted hydraulically for direct dumping. Full operation can be controlled from cabin or rear‑side panel. Application Fields Municipal Sanitation: Sludge cleaning for urban sewers, rainwater wells, septic tanks and sediment tanks; pipeline blockage removal. Residential Property Management: Routine septic‑tank cleaning and underground sewage pipe unclogging for residential communities. Construction Sites: Suction and transfer of foundation pit water, construction mud and sediment‑tank waste. Livestock Industry: Collection of manure and sewage from farm waste ponds and pen waste treatment. Key Advantages ‑ Strong vacuum suction performance with long suction distance ‑ Dual‑mode discharge: positive‑pressure ejection & hydraulic tilting self‑unloading ‑ Fully sealed tank structure, effectively prevents waste leakage & secondary pollution ‑ Simple operation, controllable from driving cabin or rear‑operation station
