Ceramic UHP Plunger | .875 OD | 90K | HJ-72162253
The HJ Waterjet Ceramic UHP Plunger (.875 OD) | HJ-72162253 is a precision-engineered replacement component designed for 90,000 PSI (6,200 bar) ultra-high-pressure intensifier pumps. Manufactured from premium high-density technical ceramic, this HJ-72162253 Ceramic UHP Plunger delivers exceptional wear resistance, dimensional accuracy, and surface finish to maximize seal life and maintain consistent pressure throughout demanding cutting operations.
This HJ-72162253 Ceramic UHP Plunger fits compatible PRO-III 90K intensifier pumps utilizing .875-inch plunger assemblies. The part is manufactured to OEM specifications for seamless installation and dependable long-term performance.
Unlike conventional carbide plungers, advanced ceramic construction provides a smoother operating surface, reducing friction against high-pressure seals while minimizing heat generation and wear. The result is improved sealing performance, lower maintenance costs, fewer unplanned shutdowns, and increased pump reliability.
Whether cutting aerospace alloys, hardened steel, titanium, stone, composites, glass, or thick plate materials, this plunger maintains the dimensional stability and surface integrity required for consistent ultra-high-pressure waterjet performance.
