tungsten carbide plunger can be customized following your drawing or sample

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.

 With unmatched wear resistant and a high polished finish for extreme pressure pumping of various fluids and gasses, our high pressure plungers will increase your pump’s internal life cycle.

Application

- Components (pistons) for high-pressure compressors

- High-pressure plunger pumps

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.
