Diesel Engine Fuel Pump 9520A940G Featuring a high-strength alloy steel pump body structure, precision-cast and surface-hardened, it boasts excellent pressure resistance and wear resistance, capable of withstanding fuel pressures up to 250 bar. The internal core plunger assembly employs a double-seal design, coupled with an intelligent electronic metering unit, ensuring fuel injection accuracy within ±0.5%, guaranteeing complete engine combustion and reducing fuel consumption and emissions. The pump body integrates efficient heat dissipation channels, effectively dispersing heat generated during high-pressure operation and preventing performance degradation due to excessively high oil temperatures. Addressing the vibration characteristics of heavy-duty equipment, this model features an optimized shock-absorbing structure, reducing the impact of vibration on internal components and extending service life through reinforced mounting brackets and elastic seals. Its fully sealed protection design achieves an IP67 rating, resisting corrosion from harsh environments such as dust and moisture, and is compatible with standard diesel and low-sulfur fuels, making it suitable for various demanding operating scenarios.

FAQ
Q: Is this oil pump suitable for marine power systems?
A: Yes, its enhanced pressure resistance and corrosion-resistant design are suitable for the working environment of marine diesel engines. However, specific compatibility with the engine model and installation interface needs to be confirmed. It is recommended to provide the marine power system parameters for matching verification.
Q: What should I do if fuel leakage occurs during use?
A: First, stop the pump and depressurize. Check if the interface gasket is aged or the mounting bolts are loose. Replace any damaged seals and tighten the interface to the standard torque. If the pump itself is leaking, it may be due to wear on the plunger assembly or a crack in the housing. Immediately stop using the pump and contact a professional repair shop to avoid the risk of high-pressure fuel injection.
Q: What are the maintenance requirements for this model of oil pump?
A: It is recommended to perform maintenance every 2000 hours or every six months. Key aspects include replacing the fuel filter, checking the condition of the seals, and cleaning the cooling channels. A comprehensive inspection should be performed every 8000 hours, including pressure calibration and plunger assembly wear inspection to ensure stable performance.
