Plungers 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.

Detail Information

1. Material: WC+Ni/WC+Co

2. Grade:YN8 YG11 YG8  

3. Hardness: HRA89-90   Bending strength:3500

3. Size: Dia22*265mm    can make following drawing

4. Features: High Wear Resistance, Corrosion Resistance

5. Surface finishing: Ra0.2-0.4

6. Straightness:0.005

7. Technology: HIP sintering

 All technical data only for reference. We can make based on requirement

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.
