Ceramic Plunger, HP/UHP, .875 OD, 60K–90K PSI | HJ-05119151
The Ceramic Plunger, .875 OD, 60K–90K PSI (HJ-05119151) is a precision-engineered high-pressure and ultra-high-pressure all-ceramic plunger designed to deliver maximum durability, superior sealing performance, and consistent pressure generation in demanding industrial applications.
Manufactured from advanced engineered all- ceramic composition, the HJ-05119151 Ceramic Plunger offers exceptional resistance to abrasion, thermal stress, and high-cycle fatigue, making it ideal for continuous operation in 60,000 to 90,000 PSI (4,100–6,200 bar) KMT-style intensifier waterjet systems.
As a critical moving component within the intensifier pump, the ceramic plunger converts hydraulic energy into ultra-high-pressure water flow, directly impacting cutting power, efficiency, and system reliability.

- Ultra-high-pressure intensifier pumps
- Industrial cutting (metal, stone, glass, composites cutting)
- Automotive manufacturing (robotic cutting and trimming)
Why Choose a Ceramic Plunger?
Ceramic plungers have become the preferred choice for modern waterjet intensifier pumps because they outperform traditional carbide plungers in demanding applications.
Advantages of Ceramic Over Tungsten Carbide
- Significantly longer HP seal life
- Lower coefficient of friction
- Improved resistance to scoring
- Superior resistance to chemical attack
- Reduced heat generation
- Longer plunger service life
- Lower total cost of ownership
- Improved pump reliability
When using ceramic plungers instead of tungsten carbide, you get longer life on HP seals and the plunger itself, reducing overall maintenance costs and increasing equipment productivity.
