Plunger & Barrel

One of the main parts of the Fuel Injection Pump. The plunger piston pressurizes the fuel oil introduced into the barrel and sends it out to the discharge valve side.
We are proud of our high reliability and quality thanks to our high-precision machining/measurement technology and surface treatment technology.


  • High durability to withstand high pressure up to 160 MPa
  • Compatible with various fuel oils such as low sulfur MGO and low quality HFO
