ISUZU 12 CBM Vacuum Suction Truck
The ISUZU 12 CBM Vacuum Suction Truck is a heavy-duty sanitation vehicle designed for municipal sewer maintenance, septic tank emptying, wastewater collection, sludge removal, and drainage pipeline cleaning. Built on the ISUZU GIGA QL1250U1QDZY 6×4 chassis, this truck combines a powerful diesel engine, a large-capacity tank system, and specialized vacuum suction and high-pressure water jetting equipment to support demanding cleaning operations in urban infrastructure, industrial facilities, and municipal drainage networks. With overall dimensions of 8500 × 2550 × 3160 mm and a wheelbase of 3985 + 1370 mm, the vehicle provides a practical configuration for carrying out heavy-duty sanitation work while maintaining the structural capacity required for its specialized equipment.
Powered by the ISUZU 6UZ1-TCG51 inline six-cylinder, turbocharged and intercooled diesel engine, the truck delivers a rated output of 350 HP from a displacement of 9,839 cc, providing the power needed for road transportation and operation of the auxiliary cleaning systems when correctly configured. The engine is paired with a FAST 12-speed manual transmission with 12 forward gears and two reverse gears, while the left-hand-drive cab and power steering help the driver maneuver the vehicle during daily transportation and maintenance assignments. With a proposed gross vehicle weight of 21,700 kg, a rated payload of 10,000 kg, and 12R22.5 18PR radial steel tires, the truck is designed for demanding commercial and municipal applications, subject to confirmation of the certified chassis ratings and applicable road regulations.
The truck features a nominal 12,000-liter combined tank system, configured with a 6,000-liter sewage compartment and a 6,000-liter clean-water compartment for vacuum collection and high-pressure sewer jetting operations. The tank body and end plates are specified as 6 mm thick Q235-B carbon steel, providing a robust structure for routine wastewater handling and cleaning work. An Italian MORO PM80 vacuum pump supports the suction system, while an Italian UDOR HX-A 250/160 R high-pressure pump is specified for sewer flushing and blockage removal. This combination enables the vehicle to collect sewage and sludge while also directing high-pressure water into drainage pipelines to loosen accumulated deposits and improve cleaning efficiency.
For customers comparing specialized municipal vehicles, this model can be considered alongside the vacuum trucks designed for waste and sludge collection, sewer cleaning trucks developed for drainage maintenance, and sewer jetting trucks equipped for high-pressure pipeline flushing. With its combined suction and jetting configuration, the ISUZU 12 CBM model offers a versatile solution for contractors and public utilities that need to manage several sewer maintenance tasks with one vehicle.
Features
1. Powerful ISUZU GIGA Chassis and Diesel Engine
The ISUZU GIGA chassis provides the foundation for a heavy-duty sanitation vehicle intended for regular operation on municipal roads, industrial sites, and infrastructure maintenance routes. Its 6×4 drive configuration, 350 HP ISUZU 6UZ1-TCG51 engine, and FAST 12-speed transmission are specified to deliver the power and gear selection required for a loaded commercial vehicle operating across different road conditions. The power steering system supports maneuverability during worksite access and positioning, while the 90 km/h stated maximum driving speed allows the truck to travel between service locations when permitted by road conditions and local regulations.
2. Large-Capacity Combined Tank Construction
The 12 CBM tank system is divided into two nominal 6,000-liter compartments, one for sewage collection and the other for clean water used by the jetting system. The Q235-B carbon-steel construction, with a specified 6 mm tank body and end plates, is intended to provide durability under normal operating conditions, while the compartmentalized design allows suction and flushing functions to be coordinated during sewer maintenance work. The tank color can be customized according to customer requirements, making it possible to align the vehicle with a municipal fleet or a company’s operating identity.
The rear tank cover is designed for hydraulic opening with a manual locking mechanism, providing access for inspection, cleaning, and maintenance when the tank has been safely isolated and prepared for servicing. A DN100 mm inlet valve and a DN150 mm outlet valve are specified for sewage handling, while the float ball alarm helps alert the operator as the sewage compartment approaches its filling limit.
3. Italian MORO Vacuum Suction System
The truck is equipped with one MORO PM80 vacuum pump, specified with a nominal pumping capacity of 12,000 liters per minute, a continuous-duty vacuum level of 80%, and a maximum vacuum level of 95%. The vacuum system is intended to draw sewage, sludge, and wastewater through the suction pipe into the designated tank compartment, making the vehicle suitable for septic tank servicing, municipal drainage maintenance, and industrial wastewater collection.
An 8-meter suction pipe is included to provide flexibility when accessing inspection chambers, underground drainage openings, and other collection points. The specified water-gas separator helps reduce liquid carryover into the vacuum airflow, while the oil-gas separator supports the management of oil mist within the system. These components, together with the pressure gauge and associated control valves, contribute to the operation and monitoring of the suction equipment. Final vacuum performance, airflow, and power requirements should be confirmed against the vacuum pump manufacturer’s documentation.
4. High-Pressure Sewer Jetting Performance
The UDOR HX-A 250/160 R high-pressure pump is specified with a working pressure of 160 bar and a flow capacity of 267 liters per minute, providing the basis for high-pressure water flushing in drainage and sewer cleaning applications. Water is delivered through a 1-inch jetting hose stored on the rear-mounted hose reel, with a specified hose length of up to 120 meters to help operators reach pipeline sections that are not immediately accessible from the truck’s parking position.
Ten high-pressure spray nozzles are included in the proposed configuration, allowing suitable nozzle arrangements to be selected according to pipeline diameter, blockage type, and cleaning requirements. The water jetting system can help loosen sediment, grease deposits, and accumulated debris from pipe walls, while the vacuum equipment can collect wastewater and sludge generated during cleaning. Actual nozzle selection, working pressure, and water flow should be matched to the pump manufacturer’s operating limits and the specific cleaning task.
5. Integrated Components for Daily Sewer Maintenance
The vehicle incorporates a range of components intended to support practical operation and routine maintenance, including a multi-way valve, pressure gauge, float ball alarm, water-gas separator, oil-gas separator, side pipe storage boxes, and protective nets on both sides where required by the final design. The combined tank layout and rear hose reel keep essential equipment organized, helping operators prepare for jobs and manage hoses during sewer maintenance activities.
The inlet and outlet valves provide designated connections for sewage handling, while the rear tank cover facilitates access for approved inspection and cleaning procedures. The integrated vacuum and jetting functions make this truck suitable for municipal sanitation departments, sewer maintenance contractors, industrial facilities, and wastewater service providers that need equipment for both liquid waste collection and high-pressure drain cleaning.
6. Wide Range of Municipal and Industrial Applications
The ISUZU 12 CBM Vacuum Suction Truck can be configured for work involving municipal sewer networks, septic tanks, drainage channels, wastewater collection points, and industrial sewage systems. During routine maintenance, the high-pressure jetting equipment can loosen accumulated deposits inside pipelines, while the vacuum suction system can collect wastewater and sludge from accessible chambers and collection points. This combination can reduce the need to deploy separate vehicles for certain cleaning operations, depending on the site’s requirements and the type of waste being handled.
For fleet operators, the truck provides a practical platform for combining suction, collection, and pipeline flushing tasks in a single specialized vehicle. Its final operating suitability depends on the verified tank capacity, certified vehicle weight, pump performance, local emissions requirements, and the safety procedures established for the material being collected.
