What is the X5 fuel injection pump head?
In diesel fuel injection pump terminology (especially in Yanmar / industrial pumps), the “pump head” or “head rotor” refers to the rotating part inside a mechanical fuel injection pump that houses the pumping elements and controls delivery timing and flow. It’s essentially the core of the high-pressure pumping section that works with plungers/rotors to pressurize fuel.
Why choose the X5 fuel injection pump head?
High-precision fuel delivery
-
The X5 pump head (also called head rotor) is manufactured with tight machining tolerances
-
Ensures stable high-pressure fuel output
-
Helps achieve smooth engine running, easier starting, and better combustion
