PLUNGER, CERAMIC, HP, 1.125 OD, 60K

HJ-05144506

KMT PART NUMBER: 05144506

The innovation of HJ Waterjet, Inc.’s 100% ceramic plunger lies in its all-ceramic composition, which offers a significant advantage over traditional piston plungers with metal shoulders.  The ceramic material provides a smoother operation and greater reliability, which in turn extends the seal life of the pump.  Furthermore, the absence of metal eliminates the risk of component separation caused by varying thermal expansion rates, ensuring a more consistent and maintenance-free performance.

Plunger, Ceramic, HP, 1.125 OD, 60K | HJ-05144506

 

The HJ Waterjet Upgraded Full Ceramic Construction HJ-05144506 Full Ceramic High-Pressure Plunger (1.125" OD) is a premium replacement component engineered for ultra-high-pressure waterjet intensifier pumps operating at 60,000 PSI (4,100 bar). Manufactured using an advanced one-piece full ceramic design, this HJ-05144506 Full Ceramic Plunger delivers exceptional wear resistance, superior surface finish, and outstanding dimensional stability under continuous high-pressure operation.

This HJ-05144506 full ceramic plunger is compatible with SL-V and SL-VI intensifier pumps rated from 75 to 200 horsepower. It provides high-level performance while reducing maintenance costs and increasing overall pump reliability.

Unlike traditional tungsten carbide plungers, the HJ Waterjet full ceramic plunger features a completely ceramic construction that minimizes friction and dramatically reduces wear on high-pressure seals. The ultra-smooth ceramic surface maintains sealing integrity for longer periods, helping extend maintenance intervals while improving pump efficiency.
