An Isuzu KV100 combined jetting and suction truck is a compact two-system vehicle for work that needs high-pressure pipe cleaning and vacuum recovery on the same service visit. The reference configuration in this guide combines a water jetting system, a sewage suction system, separate clean-water and sewage tanks, and remote-assisted operating controls on an Isuzu KV100 chassis.
This type of truck is useful for municipal maintenance teams, drainage contractors and service operators that need to flush deposits from pipes before collecting the resulting sewage, silt and wastewater. It is not simply a suction tanker with a water tank added. The tank split, pump capacity, hose reel, vacuum system and protection devices all need to work together around the daily route.
Reference Vehicle Overview
The supplied configuration is based on an Isuzu KV100 chassis with a 3,360 mm wheelbase, 7,300 kg GVW reference and a 140 HP diesel engine. The engine is specified as Euro VI, with a five-speed manual transmission, ABS, air brakes, power steering and air conditioning.
The vehicle uses separate tanks for clean water and recovered sewage. The supplied reference lists a 1.5 m3 clean-water tank and a 3.5 m3 sewage tank. Final usable volume should always be confirmed against the selected tank geometry, payload limit and local road requirements.
High-Pressure Jetting System
The jetting side of this configuration uses an imported three-plunger high-pressure pump. The supplied reference specifies 130 L/min flow at 16 MPa. This gives the truck a practical cleaning system for deposits, silt and routine blockage removal in drainage and sewer lines.
A rear-mounted hydraulic hose reel carries 100 m of 19 mm high-pressure hose. The reel can rotate through 180 degrees and uses hydraulic retraction and extension. Wireless, electric and manual controls give the operator several ways to manage the hose at the work site.
The specified protection package includes a sight gauge, three-stage filtration, water-particle filtration protection, winter anti-freezing protection and manual plus electric pressure regulation. These details matter because a jetting system is only reliable when its water supply and pump protection are matched to the operating environment.
Vacuum Recovery System
After jetting loosens material in a line or manhole, the vacuum system collects it into the sewage tank. The supplied configuration specifies a PN84D vacuum pump with a reference vacuum level of -0.93 bar and airflow of 9,000 L/min.
The document also lists a vertical suction lift of at least 10 m and a horizontal suction distance of at least 50 m. Actual suction performance depends on the material, hose diameter, altitude, pipe route, tank level and operating condition, so these figures should be treated as configuration references rather than universal job-site guarantees.
The vacuum protection arrangement includes a pneumatic anti-overflow valve, cyclone separator and air-intake filtration. Together with positive and negative pressure relief protection, these components help protect the tank and vacuum system during routine operation.
Tank, Discharge and Safety Design
The reference tank is made from Q235 steel plate with 6 mm head plates, automatic-welded forming, internal anti-wave baffles and electrophoretic anti-corrosion treatment. A hydraulic lifting system with a bottom-mounted cylinder provides a reference lifting angle of at least 45 degrees for discharge. A mechanical locking device is included as part of the lifting safety arrangement.
The truck also includes low-water and overflow alarms, vacuum protection, high-pressure pump water-shortage protection, an emergency stop function and work warning lights for night operation. These are the kinds of details buyers should compare when reviewing a compact combined truck, not only the tank volume and pump figures.
Control System and Standard Tools
The supplied vehicle uses a CAN bus control system with a stainless-steel electrical control cabinet, LCD display and wireless remote control. The display provides operating information such as vacuum level, high pressure and engine speed.
The listed tools include a root-cutting nozzle, diamond nozzle, rotary mushroom nozzle, hand-held cleaning spray gun, 100 m high-pressure hose, 80 m DN100 sewage suction hose and vacuum-pipe quick connectors. Final nozzle selection should match the pipe diameter, deposit type and local maintenance routine.
When This Configuration Is a Good Fit
This compact combined configuration can be considered when one team needs to alternate between pipe cleaning and waste recovery, especially for:
- Municipal drainage and manhole maintenance
- Sewer and storm-drain cleaning routes
- Small and medium pipe blockage work
- Service work that requires both jetting and sludge recovery
- Contractors that need a maneuverable chassis rather than a large heavy-duty platform
For work focused only on septic collection or liquid-waste transport, a standard sewage suction truck can be simpler. For larger municipal routes or heavier continuous-duty work, buyers may need a larger chassis, a different water-to-sewage tank split or a higher-capacity pump package.

Questions to Confirm Before Quotation
Before finalizing a similar vehicle, buyers should provide the normal pipe diameter, blockage type, material to recover, daily route length, expected suction distance, clean-water demand, destination market and preferred chassis brand. These details determine whether the reference 1.5 m3 water and 3.5 m3 sewage arrangement is suitable, or whether another tank split and system layout is needed.
Frequently Asked Questions
Is this a standard sewage suction truck?
No. It combines high-pressure jetting with vacuum recovery. The jetting side cleans the pipe, while the vacuum side collects the resulting sewage, silt and wastewater.
Can the tank sizes be changed?
Yes. Tank capacity and the clean-water to sewage-tank split should be selected around the working route, payload, local regulations and expected water consumption.
Are the performance figures fixed for every job?
No. Pump flow, pressure and vacuum references describe this supplied configuration. Real job-site performance changes with the material, hose layout, pipe condition and operating environment.
