The split side-mounted tank keeps clean water and sewage in separate compartments, so a single pass handles both high-pressure jetting and vacuum extraction for roughly double the working efficiency.

The proven Dongfeng Duolika chassis brings a wide service network and low-cost parts, while the yellow vacuum tank body delivers strong single-pass suction performance.

Built on the comfort-spec Delong L5000 chassis with original Shacman quality, its vacuum tank body draws sludge and sewage at high volume for municipal and industrial duty.

The 22 m3 tank is fabricated in 8 mm carbon steel with two interconnected compartments controlled by a 100 mm ball valve, and carries a Pinfu 350 L/min high-pressure pump with 100 m of hose alongside a Weichai 420 hp auxiliary engine driving a 2BE258 water-ring vacuum pump.

The sewage tank is fabricated in high-grade carbon steel with 5 m3 of sewage capacity and 2 m3 of clean water. The 215 high-pressure pump carries a filter, interconnected tanks, 60 m of 19 mm double-layer hose and 10 combination nozzles, while the SK-9 water-ring vacuum pump with forced discharge runs 8 m of suction hose and interconnected water and sewage circuits.

The tanks are fabricated in 8 mm carbon steel with 5 m3 of clean water and the remainder sewage, two compartments interconnected through a 100 mm ball valve with dish-end baffles and a stainless steel lined interior. A Tongjie 350 L/min high-pressure pump with dual water supply and air-blow drying works alongside a 420 hp auxiliary engine driving a 2BE258 water-ring vacuum pump, plus an additional slurry pump with a hydraulically controlled hose reel and 2 x 30 m flow and return hoses.

The water tank is built in 4 mm national-standard carbon steel and the sewage tank in 5 mm carbon steel. A Xinfupin UV215 high-pressure pump rated 20 MPa feeds 60 m of 19 mm hose, while a Shandong SK-9 fully sealed water-ring pump with anti-overflow valve and sight glass runs an 8 m suction hose with quick couplings. The tank dished heads are pressed in one piece and the tank tips, with a hydraulically opened rear cover.

The approximately 15 m3 tank uses an interconnected water and sewage structure with multiple anti-overflow protections. A Pinfu 255 high-pressure pump drives the jetting circuit while an SK-30 water-ring vacuum pump handles suction, and the hose reel rotates 180 degrees hydraulically. The model is China VI and qualifies for purchase-tax exemption.
