FAQ

Q1: How do I verify if this rotor head fits my DPA pump?
A: Check your existing part number against our OEM cross-reference list (7123-340J, 7180-550J, 344J, or 558A). If your pump uses these numbers, the rotor head is compatible. For uncertain applications, please contact our support team with your pump model and serial number for verification.

Q2: What is the recommended installation procedure?
A: Installation should be performed by a qualified diesel mechanic. Ensure the pump is clean and free of debris. Apply a thin layer of clean diesel fuel to the rotor head during installation to prevent seizing. Torque to manufacturer specifications and test for leaks before reassembly.

Q3: How should I maintain the rotor head for optimal lifespan?
A: Use only high-quality, clean diesel fuel and replace fuel filters regularly. Contaminated fuel is the leading cause of premature wear. During routine pump servicing, inspect the rotor head for scoring or pitting. Our high-speed steel construction offers excellent longevity under normal operating conditions.
