Product Introduction

The ceramic piston rod, also called a ceramic plunger, is an important wear part used in Waterjet Intensifier pumps. It moves inside the pump assembly to help generate stable high-pressure water for cutting. A precise ceramic plunger helps improve sealing performance, reduce leakage risk, and support stable pump operation.

KUNDA supplies ceramic plungers, ceramic piston rods, hydraulic cylinders, seal kits, and other Intensifier Pump replacement parts for waterjet machines. Custom dimensions, OEM supply, private label service, and bulk orders are available.

For Water Jet Pump Systems

This ceramic plunger is suitable for ultra-High Pressure Waterjet Pump systems. Accurate grinding and polishing help the plunger move smoothly, reduce friction with seals, and maintain stable pressure output during continuous cutting work.

Ceramic Material Advantage

Ceramic material offers strong wear resistance and good corrosion resistance. Compared with some metal components, a ceramic plunger can keep a smoother surface for longer use, helping reduce seal wear and maintenance frequency.

Precision Surface Finish

Surface finish is important for sealing performance. A smooth ceramic surface helps reduce leakage risk, improves hydraulic efficiency, and supports longer service life for both the plunger and the related sealing parts.

Replacement And Maintenance Use

These ceramic piston rods can be used for routine maintenance, pump rebuilding, emergency replacement, OEM production, and equipment repair. Customers can send machine model, pump type, current part number, sample, or drawing for replacement confirmation.

OEM And Custom Supply

KUNDA can provide different ceramic materials, dimensions, surface finishes, and specifications according to customer requirements. Custom packaging, private label service, OEM manufacturing, and bulk supply are available.
