Dongfeng Fuel Tanker Aviation Helicopter Aircraft Refueling Dispenser Truck

Aircraft fuel dispenser truck (often called a hydrant dispenser or hydrant servicer) is a specialized vehicle designed to transfer aviation fuel from an airport’s underground pipeline system directly into an aircraft.

Unlike a standard tanker truck, a dispenser does not carry fuel in a large tank. Instead, it acts as a high-tech mobile "bridge" that filters, measures, and regulates the pressure of the fuel coming from the ground.

Intake: The truck connects a heavy-duty intake hose to a "hydrant pit" (a valve in the concrete on the airport ramp).
Processing: Fuel flows from the underground pipes into the truck's internal system. It passes through a filter separator to remove water and contaminants.
Regulation: A pressure control valve ensures the fuel enters the aircraft at the correct pressure (usually around 45–55 psi) to avoid damaging the wing tanks.
Delivery: The fuel is pumped into the aircraft through hoses connected to the plane's underwing refueling points.

Hydrant Coupler: The specialized connector that plugs into the ground pit.
Filter Separator: Crucial for safety; it removes particulates and moisture from the fuel.
Flow Meter: High-precision digital meters that track exactly how many gallons/liters are delivered for billing and weight calculations.
Deadman Control: A hand-held switch that the operator must hold constantly. If they let go, the fuel flow immediately stops—a critical safety feature.
Elevating Platform: Many dispensers have a lift to reach the refueling ports on high-wing aircraft like the Boeing 777 or Airbus A380.

Dongfeng Hydrant Dispenser Trucks
These are high-performance vehicles designed for major airports with hydrant systems. They act as a mobile regulation and filtration unit.

Chassis: Typically built on the Dongfeng Tianjin or DFH series (4x2 or 6x4 configurations).
Flow Rates: * Single Hose: Up to 1,000–1,200 L/min.
Double Hose/Platform: Up to 3,800–4,000 L/min (for wide-body jets).

Key Features:
Filter Separator: Complies with EI 1581 standards (latest editions) for water and particulate removal.
Pressure Control: Dual-layered system (inline and deadman) to prevent wing-tank overpressurization.
Lift Platform: Most models include a scissor-lift platform (reaching ~4.6m) to reach underwing ports of aircraft like the Boeing 777 or Airbus A350.
Materials: All piping is typically Stainless Steel (AISI 304) or aluminum alloy to prevent corrosion and fuel contamination.

2. Dongfeng Refueller Trucks (Mobile Dispensers)
In many regions, Dongfeng provides "dispenser trucks" that include a storage tank (often used at smaller airports or for remote refueling).
Capacity Options: Common sizes include 5,000L, 10,000L, 20,000L, and up to 32,000L.
Tank Material: High-grade Aluminum Alloy (5182 or 5083) or Stainless Steel. Aluminum is preferred for Jet A-1 to prevent rusting and reduce vehicle weight.
Performance:
Engine: Often powered by Cummins or Yuchai diesel engines (120HP to 300HP).
Pumping System: Self-priming centrifugal pumps (e.g., Hangzhou Weilong) with specialized explosion-proof cabinets.
Flow Metering: High-precision flow meters (accuracy ±0.2%) with digital displays.

3. Safety & Compliance Specifications
Dongfeng aircraft fuel vehicles are engineered to meet international aviation standards (JIG, NFPA 407, and ATA 103):
Deadman System: Pneumatic or electric hand-held controls that stop flow instantly if the operator is incapacitated.
Interlock System: Prevents the truck from moving if the hoses are still connected or the platform is raised.
Static Safety: Equipped with static conductive wire reels and explosion-proof electrical systems.
Filtration: 7-core or higher filtration systems (coalescer and separator elements) to ensure fuel purity.
