Tank capacity customizedThis 2026 new design ISUZU septic pump truck is built on the original Isuzu KV800 Class II chassis with a 4125mm wheelbase. The power system features an Isuzu 4JZ1 180hp diesel engine paired with a MYY-6-speed manual transmission, ensuring stable power output. The vehicle is equipped with an 8-cubic-meter sewage tank, which is highly pressure-resistant, corrosion-resistant, and not easily deformed. The core suction component uses the well-known brand SK-12 water-circulating vacuum pump, providing outstanding operating efficiency and achieving a vacuum level of up to 93%. It can quickly suction and discharge sludge, septic tank sewage, and sewer silt, making it suitable for various scenarios such as municipal sanitation, community sewage treatment, and river dredging.

▶ Chassis and Powertrain:

• Chassis Brand: Isuzu KV800
• Wheelbase: 4125mm
• Engine: Isuzu 4JZ1-TCG62 Inline 4-Cylinder Diesel Engine
o Horsepower: 180 hp/133 kW
o Emissions: 2.999L
• Transmission: Isuzu Original MYY-6-Speed Manual Transmission
▶ Sewage tank:

• Effective volume: 8 cubic meters
• Material: Carbon steel (Q235B), 5mm thick, anti-corrosion treatment
• Structure: Integral welded, with baffle plate
▶ Vacuum Pump:

• Model: SK-12 Water Circulation Vacuum Pump, a well-known Chinese brand
• Technical Advantages: Utilizes a water circulation cooling design, resulting in low temperature rise during continuous operation; more environmentally friendly than traditional oil pumps, reducing oil mist generation.
• Performance Parameters: Maximum pumping capacity 12 m³/min, ultimate vacuum -0.093 MPa, pump speed 970 r/min
• Performance Characteristics: Suction lift up to 7 meters, fast suction and discharge speed, easily removes sludge, sewage, mud, and small particulate impurities.
▶ Operation and Other Configurations:

Operation: The driver-side manual hydraulic control lever controls the raising and lowering of the tank and the opening/closing of the tailgate.
Other Configurations: Sight glass, secondary filter, hydraulic oil tank, overflow valve, tail suction valve, drain valve
▶ Working Principle:
1. This vehicle utilizes the principle of air pressure difference for suction and discharge operations. During operation, the engine drives the SK-12 water-circulating vacuum pump to continuously draw air from the sealed tank, creating a vacuum negative pressure state inside. External atmospheric pressure then forces sludge and wastewater into the tank through the suction pipe, achieving rapid suction. The tank is equipped with an overflow prevention device that automatically closes the suction port when the liquid level reaches a certain percentage, preventing waste from entering the vacuum pump.

2. There are two methods for unloading: one is to switch the air path to reverse the pressure of the vacuum pump into the tank, forcing the waste out; the other is to hydraulically lift the tank and open the rear gate to achieve gravity unloading. The entire process is efficient and safe.
▶ Applicable scenarios:
• Dredging and suction of urban sewers, rainwater wells and sedimentation tanks
• Cleaning and transfer of factory septic tanks and grease traps
• Liquid waste suction in farms and sewage treatment plants
• Rapid removal of construction site mud and river silt
