3. Working Principle
This is a low-pressure fuel transfer pump, installed between the fuel tank and high-pressure fuel pump.
- Motor Drive: The 24V DC motor drives the roller pump chamber to rotate.
- Suction & Pressurization: It creates negative pressure to draw fuel from the tank and pressurize fuel to 0.3–0.5 MPa.
- Pressure Stabilization: Equipped with built-in check valve and safety valve to stabilize fuel pressure and protect the high-pressure fuel pump.
- Filtration Protection: Integrated metal filter at the inlet to remove impurities preliminarily.
4. Technical Specifications
Operating Voltage: 24V DC
Output Pressure: 0.3–0.5 MPa (3–5 bar)
Flow Rate: ≥ 1.8 L/min (≥ 108 L/h)
Operating Temperature: -40℃ ~ +85℃
Ingress Protection: IP67 (Dustproof and splash-proof)
Installation Method: Horizontal bolt fastening with shock-absorbing pads to reduce vibration and noise.
5. Main Functions
- Stable Low-pressure Fuel Supply: Delivers continuous, clean and pressure-stabilized diesel to the high-pressure fuel pump and maintains stable injection pressure.
- Cold Start Assistance: High-power 24V design ensures quick and reliable startup in low-temperature environments.
- Vapor Lock Prevention: Forced fuel delivery reduces engine stall caused by fuel vapor lock under high temperature or high altitude conditions.
- Precision Component Protection: The internal filter blocks impurities and extends the service life of high-pressure fuel pumps and fuel injectors.
6. Common Faults & Impacts
Malfunction Symptoms
- Difficult cold start and unstable idling
- Slow acceleration and insufficient power
- Occasional stall during operation
- Abnormally high fuel consumption
Common Trouble Codes
P0230 (Fuel Pump Circuit Malfunction), P0089 (Fuel Pressure Abnormality)
Long-term Consequences
Abnormal wear of high-pressure fuel pump, clogged fuel injectors and severe power loss of the engine.
7. Installation Instructions
- Installation Position: Near the fuel tank or frame side beam for easy maintenance.
- Fuel Pipe: Standard M14×1.5 thread, matched with oil-resistant high-pressure fuel hoses.
- Electrical Connection: 3-pin connector (Power, ground, signal) with waterproof sealing.
- Fastening Method: Fixed with two bolts and shock-absorbing pads to avoid vibration transmission.
8. Product Advantages
