SINOTRUK HOWO 6×4 Dry Powder & Water Combined Fire Pumper — Complete Professional Introduction
1. Product Overview
The SINOTRUK HOWO 6×4 Dry Powder & Water Combined Fire Pumper is a heavy-duty, multi-functional emergency fire rescue vehicle developed based on the mature SINOTRUK heavy-duty 6×4 chassis. Designed for high-risk and complex fire scenarios, the truck integrates dual fire-extinguishing systems: a high-flow water spray system and a high-pressure dry powder spraying system. It is equipped with independent anti-corrosion water storage tank and sealed dry powder tank, professional fire centrifugal pump, vacuum priming pump, and 360° rotating multifunctional fire monitor.
Powered by a high-power diesel engine, the vehicle delivers stable power output, strong climbing performance and excellent cross-country adaptability. The fully enclosed integrated pump cabin, centralized electric control system and complete warning lighting equipment ensure safe, convenient and efficient on-site operation. This fire truck can handle Class A solid fires, Class B oil liquid fires, electrical equipment fires, gas fires and dangerous chemical fires, serving as an all-round fire rescue equipment for industrial and municipal fire protection.
2. Working Principle
The vehicle adopts an independent dual-media fire-extinguishing working mechanism, which can switch freely between water fire suppression and dry powder fire suppression, or perform combined operation:
Water fire extinguishing system: The engine drives the power take-off to operate the high-flow fire pump and vacuum priming pump. The device quickly absorbs water from the onboard tank or external water sources. Through pipeline pressurization, the fire monitor outputs straight-flow high-pressure water or fine water mist to cool down high-temperature combustion objects, isolate heat radiation, and extinguish solid building fires and general liquid fires.
Dry powder fire extinguishing system: Compressed air provides stable pressure for the sealed dry powder tank. Under precise pneumatic control, dry powder is ejected at high speed through a special powder spraying pipeline. The dense dry powder cloud can quickly cover the combustion surface, isolate oxygen, interrupt the combustion chain reaction, and achieve rapid fire extinguishing and anti-re-ignition effects.
Combined working mode: Water mist cools the fire scene in real time, while dry powder covers and suppresses open flames, realizing dual protection of cooling and fire blocking, which greatly improves the success rate of rescuing complex dangerous fires.
3. Real Application Scenarios in Daily Operations
This multi-functional combined fire truck is widely applicable to high-risk fire rescue scenarios that ordinary single water tank fire trucks cannot cope with:
First, it is suitable for petrochemical parks, oil depots, gas stations and chemical plants, effectively rescuing oil material combustion, chemical solvent fires and flammable gas leakage and combustion accidents. Second, it perfectly matches power stations, substation centers and electrical industrial zones, using dry powder to safely extinguish electrical fires without electric conduction risks.
In addition, it can serve large industrial mines, ports and logistics parks to deal with mechanical equipment fires and cargo spontaneous combustion. It is also the core emergency equipment for urban main fire stations, capable of daily fire patrols, urban building fire rescue, on-site cooling, fire isolation and long-distance water supply, fully meeting long-term and high-intensity emergency rescue needs.
4. Comparison with Traditional Fire Trucks
Compared with traditional single water tank fire trucks and small dry powder fire trucks, the HOWO 6×4 combined fire pumper has obvious comprehensive advantages:
First, richer fire-extinguishing functions. Traditional
Water Fire Trucks can only extinguish common solid fires and are ineffective for electrical fires, oil fires and gas fires; single dry powder trucks have poor cooling effect and are prone to re-ignition. This integrated model combines the advantages of water and dry powder, covering almost all common industrial and municipal fire types.
Second, stronger chassis performance. Adopting 6×4 heavy-duty rear double axle design, it has higher load-bearing capacity and more stable driving performance than traditional 4×2 fire trucks, adapting to mountain roads, muddy industrial roads and long-distance emergency driving.
Third, higher rescue efficiency. The dual-tank large-capacity design supports long-time continuous operation without frequent water and powder replenishment, solving the problem of short endurance of traditional small fire trucks.
Fourth, lower comprehensive cost. One truck replaces the functions of a water tank fire truck and a dry powder fire truck, saving equipment purchase, fleet management and later maintenance costs for customers.

5. Buying Guide: How to Choose the Right Combined Fire Pumper
When purchasing a professional dry powder and water combined fire truck, customers need to focus on the following core configurations to avoid low-efficiency and low-quality equipment:
First, confirm the chassis reliability. Prefer mature heavy-duty 6×4 commercial chassis with high-power engine, which ensures sufficient power under full-load working conditions and adapts to complex road rescue. Avoid light-duty chassis with insufficient load-bearing capacity.
Second, check tank and pipeline quality. The water tank must adopt overall anti-corrosion treatment, and the dry powder tank must be fully sealed and pressure-resistant to prevent powder moisture agglomeration and pipeline blockage. Professional integrated pump cabin and thickened fire-resistant pipelines are essential for long-term high-pressure operation.
Third, verify core fire-fighting equipment. Equipped with standard fire centrifugal pump and vacuum priming pump to ensure fast water absorption and stable water output. The fire monitor needs 360° full rotation and multi-mode switching to meet all-angle fire suppression.
Fourth, confirm export compliance. For overseas procurement, choose models that meet international emission and safety standards, with complete factory certification, inspection reports and customs clearance documents to ensure smooth export and local registration.
6. Practical Operation & Maintenance Tips
Daily Operation Specifications: Before rescue operation, preheat the engine and check the tightness of water tanks, powder tanks and all pipelines. Do not start the high-pressure pump without medium to avoid equipment damage. When switching between water spraying and powder spraying modes, stop the machine first for mode conversion to prevent pipeline pressure impact. During operation, operate the centralized electric control panel gently, and avoid overload and long-term continuous high-pressure working.
Regular Maintenance Guidelines: Conduct daily inspection of warning lights, control system and fire monitor rotation flexibility. Clean the water filter and powder pipeline filter every week to prevent blockage. Monthly check the sealing performance of the tank body, valve body and pipeline joints to avoid water leakage and powder leakage. Regularly replace hydraulic oil and lubricate movable parts. For long-term idle vehicles, drain the residual water in the tank, clean the dry powder tank thoroughly, and park in a dry and ventilated environment to avoid rust and powder deterioration. Standard maintenance can greatly extend the service life of fire-fighting systems and chassis equipment.
