FAQ

Q1: How do I confirm this head rotor is compatible with my specific DPA pump?
A1: The surest method is to match the part number stamped on your original component. This part replaces 7139-235F / 7139235F. For further verification, please provide the pump model and serial number, or the engine model and equipment make (e.g., excavator, generator set) to our support team.

Q2: What is the importance of the High-Speed Steel material in this application?
A2> High-Speed Steel (HSS) is essential for the head rotor due to its exceptional resistance to wear, heat, and deformation. Inside the fuel pump, the rotor spins at high speed under extreme pressure. HSS maintains its precise tolerances far longer than standard steels, preventing fuel leakage and pressure loss, which directly impacts engine power and efficiency.

Q3: Do you provide technical support for installation?
A3> While we supply the component, installation of precision fuel injection parts requires specialized tools and knowledge. We recommend consulting the official service manual for your pump model. We can provide general dimensional specifications and material data sheets to assist qualified technicians. For complex fitment issues, our technical team is available to consult on part identification.
