● Current Market Situation:Many conventional water trucks used for small-to-medium-scale sanitation, construction site dust suppression, and landscaping maintenance suffer from common drawbacks: standard carbon steel tanks are prone to rusting, leaking, and contaminating the water, leading to severe corrosion and frequent repairs over time; generic water pumps deliver unstable flow and inconsistent spray patterns, resulting in uneven road washing and damage to greenery; and the vehicle itself often lacks sufficient power, struggling to operate effectively in complex road conditions.
☛ Our Trucks: This Isuzu 700P 5m³ water truck is purpose-built to address the specific pain points of high-frequency, precision operations in sanitation, landscaping, construction sites, and residential communities. By combining the proven quality of the Isuzu 700P chassis with a 304 stainless steel tank and a high-performance water pump, it effectively eliminates common issues such as tank corrosion, pump failure, insufficient power, and chassis unreliability. Offering an ideal balance of durability, stability, and maneuverability, it is the perfect vehicle for small-to-medium-scale, precision sanitation tasks.

Some water trucks suffer from underpowered chassis; they struggle to climb hills when fully loaded with five tons of water and are plagued by persistent minor engine issues. This vehicle, however, is built on an Isuzu 700P chassis powered by a 4HK1-TCG61 engine—delivering 190 horsepower and a peak torque of 507 N·m—and is equipped with an MLD 6-speed transmission. This mature, reliable powertrain handles the demands of both rural-urban roads and unpaved field tracks with ease, even when fully loaded.

The water pump system is the core of this vehicle's operational capability; its specifications and configuration are designed for high efficiency, durability, and ease of use.
☛ Flow Rate and Head: Ample Capacity with a Margin to Spare.
It comes standard with a specialized stainless steel 65QBZF-40/50N sprinkler pump, offering a flow rate of 40 m³/h. To put that in perspective, it can discharge approximately 666 liters of water per minute. With a 5-cubic-meter tank, a full load could theoretically be emptied in 7–8 minutes at maximum speed; however, in actual operation—due to nozzle diameter constraints and the pace of work—a single tank lasts 20–30 minutes, covering a road section of about 20 kilometers per fill-up. This level of efficiency is perfectly adequate for municipal sanitation and landscape irrigation tasks.

☛ All-Stainless Steel Piping: Built to Withstand Demanding Conditions.
The configuration—featuring stainless steel piping, ball valves, four-way three-port valves, and filter-equipped three-way valves—offers key advantages: corrosion resistance, immunity to rust-induced blockages, and easy maintenance. Standard iron piping often becomes unsightly with rust after just a year or two, frequently leading to seized ball valves and clogged filters. Stainless steel eliminates these issues; the system’s reliability is particularly evident when transporting drinking water or river water containing minor impurities. Furthermore, the pump delivers steady, uniform power output, ensuring consistent pressure and continuous water flow without surging or sputtering, while offering smooth start-stop operation and high suction/discharge efficiency.

☛ Versatile Spraying Capabilities
With mid-mounted flushers, rear sprinklers, side sprays, and a high-pressure landscaping cannon, this combination covers virtually all common watering scenarios:
• Mid-mounted flushers/Rear sprinklers: The primary tools for road washing and dust suppression, capable of a spraying width of approximately 12 meters.
• Side sprays (shower-style): Designed for irrigating green belts and roadside vegetation; the moderate water pressure ensures plants are not damaged.
• High-pressure landscaping cannon: Made of stainless steel and capable of full-range rotation, it offers a spraying range of 28 meters or more. It provides long-distance reach for washing tall trees and can be adjusted to a fine mist setting.

The pump utilizes an external-mixing, axial-recirculation casing structure, comprising a suction chamber, a liquid reservoir, recirculation ports, and a gas-liquid separation chamber. Upon startup, the impeller draws in the liquid stored in the suction chamber along with air from the suction pipeline, thoroughly mixing them within the impeller. Driven by centrifugal force, the mixture flows through the discharge chamber into the gas-liquid separation chamber; due to the lower density of the gas, it separates from the liquid and is discharged through the outlet pipe, while the liquid settles in the separation chamber and returns via the recirculation ports to the impeller's outer edge for another cycle of mixing and separation. This process repeats until the air in the suction pipeline is fully evacuated and replaced by liquid, thereby completing the self-priming phase. As water exits the impeller, a vacuum forms at its center, drawing water from the source reservoir through the suction pipe and into the impeller; the continuous rotation of the impeller ensures a steady cycle of water discharge and intake, resulting in continuous pumping action.

65QBZF-40/50N water sprinkler pump
1. Before startup, check that the oil level in the gearbox is sufficient. Note: After one week of use, drain the old gear oil completely and replace it with fresh gear oil.
2. Ensure there is sufficient liquid inside the pump and verify that the drain valve is closed.
3. Open the outlet valve slightly and fully open the inlet valve.
4. The pump's intake opening should be submerged at least 30 cm below the liquid surface to prevent air intake. The intake strainer must not be too fine-meshed, and it must not be clogged.
Special Precautions:
1. During test runs, the pump must be filled with liquid to prevent damage to the mechanical seal caused by dry running.
2. If the pump fails to prime within two minutes of startup (while operating within the rated self-priming lift range), stop the pump immediately. If there is no external leakage, the issue is likely an air leak or blockage in the inlet piping; inspect and rectify the problem before restarting the pump.

1. Municipal Sanitation & Road Maintenance
Used for road washing, dust suppression, and cooling during summer. Combining rear sprayers with mid-mounted side jets allows for wide coverage and high efficiency in a single pass, making it a primary tool for street cleaning.
2. Landscaping & Agricultural/Forestry Irrigation
Side jets irrigate green belts, while high-pressure cannons wash or water tall trees. It can also transport water to fields for irrigating commercial forests and saplings. A 5-cubic-meter tank allows for significant coverage in a single trip.
3. Emergency Firefighting & Fire Prevention/Humidification
Serves as a "mobile water source" for townships, forest areas, and industrial sites—handling daily dust suppression, wetting roads near forest edges during fire-prone seasons to reduce risk, and providing an immediate water supply for initial fire suppression during emergencies.
4. Construction Sites & Industrial Facilities
Effectively manages heavy dust at construction sites using mid-mounted and rear sprayers, or by using high-pressure cannons to spray a water mist that suppresses airborne dust.
