Features

Our cemented carbide plungers are used at petrochemical plants in the production of low-density polyethylene (LDPE) and ethylene vinyl acetate (EVA).
These plungers function as pistons in high-pressure compressors, where they are required to have high compressive strength, wear resistance, and erosion resistance.

Applications

  • Components (pistons) for high-pressure compressors
  • High-pressure plunger pumps

FAQ

What is the longest plunger you can produce?
It depends on the outer diameter, but the longest plunger we can produce is about 1,450 millimeters in total length.
Why is the surface given a mirror finish?
These products are used under high pressures, so there is concern that surface defects might lead to serious accidents. Applying a mirror finish to the surface makes defects easier to spot. Another benefit is that the plungers slide better within their packing.
