CNC Waterjet Ceramic Rod Replacement Precision Ground Waterjet Ceramic Plunger Rod
CNC Waterjet Ceramic Rod is a core, wear-resistant component installed in a waterjet high-pressure pump or intensifier. It primarily converts hydraulic energy into ultra-high-pressure water energy. It is an essential component of a waterJet Pump. High-quality waterjet ceramic rods can ensure more stable machine operation, reduce pump failure rates, and improve Waterjet Machine efficiency.
In Waterjet Cutting Equipment, hydraulic oil propels the ceramic rod back and forth, compressing low-pressure water into a high-pressure stream (typically 55,000–90,000 psi). This high-speed water jet is then generated by the cutting head and used to cut materials such as glass, metal, and stone.
