The Beiben 20,000-liter sewer vacuum truck is a large-scale specialized sanitation vehicle built on the BeiBen 2642 6×4 chassis. It is powered by a Weichai 420 HP engine and a Fast 12-speed manual transmission, and equipped with a 2BE‑204 water circulation vacuum pump that enables self-priming and self-discharging operations through vacuum negative pressure. The tank has a capacity of 20,000 liters, with a suction time of ≤12 minutes and an effective suction depth of no less than 8 meters. The tank can be tilted up to 45° for discharge, and the closed operation effectively minimizes secondary pollution.
With strong power and large load capacity, the vehicle has a gross weight of 26 tons. It is suitable for municipal sewer unblocking, septic tank cleaning, and industrial liquid waste and sludge collection and transport. Serving both urban sanitation and industrial/mining scenarios, it combines reliable chassis performance with efficient vacuum operation, making it a practical piece of equipment for high-volume waste collection and transport.
