Large-unit pump plungers
BALINIT C (WC/C), the carbon coating which contains metal (Me-C:H, or Me-DLC), is the standard solution for large-unit pumps and gives systems excellent galling and scuffing resistance.
Your advantages with BALINIT-coated diesel injection components:
- Excellent sliding-wear resistance (galling, scuffing) against metal counterfaces
- Enables higher injection pressure for lower consumption and emissions
- Protects against abrasive particle wear
- Protects against high-impact oscillation
