Rebuilt plungers, engineered to outlast OEM.
PK-730 tungsten carbide or PK-62 nickel chrome — the two chemistries we rebuild fracking plungers with, chosen for the specific pressure regime and wear environment.
PK-62 nickel chrome. PK-730 tungsten carbide. Chosen for the wear environment.
Fracking plungers see extreme wear — high-pressure abrasive slurries against a hardened surface, cycle after cycle. PK-62 nickel chrome is the industry-standard chemistry, and it is what Parkway-Kew rebuilds most worn plungers with. For severe-wear duty, the proprietary PK-730 chemistry adds tungsten carbide for a harder, longer-lasting surface.
When a plunger comes into the shop we run the standard engineering review: wear pattern, base metal, environment, expected service. Only then does the recommended chemistry — PK-62 or PK-730 — get committed to a quote.
- PK-62 · nickel chrome, the industry standard
- PK-730 · proprietary chemistry, added tungsten carbide for severe wear
- Selection is by wear pattern and fluid environment
- Rebuilt plungers often exceed OEM wear life
