Super Suction Vacuum Truck
Heavy-duty vacuum suction equipment for sewage, sludge, oil residue, gravel and industrial waste recovery. The truck combines strong suction performance, sealed tank transport, hydraulic discharge and practical site operation support.
High-power vacuum recovery for heavy sludge and mixed waste.
A super suction vacuum truck is built for customers who need stronger suction than ordinary septic vacuum trucks. It is used for municipal drainage, factory pits, oil sludge, gravel, slurry and mixed liquid-solid waste recovery.
Super Suction System
High-flow Roots vacuum pump, suction pipeline and protection system help recover sewage, sludge, oil residue, gravel and dense mixed waste.
Heavy-Duty Tank Transport
Sealed vacuum tank structure supports negative pressure loading and controlled transportation from work site to discharge location.
Hydraulic Operation
Hydraulic suction boom, rear door, tank lifting and discharge options can be configured around the actual job site and waste medium.
Built for municipal, industrial and construction cleaning work.
We confirm suction depth, waste medium, discharge method, road condition, tank volume and chassis requirement before recommending the final configuration.
Choose the truck by chassis, tank volume, pump and discharge method.
The same product name can cover different working conditions. The final truck should be selected around suction material, payload, pump power, tank capacity and local compliance.
