Plunger Retainer WS1025 Good Price Waterjet Parts Supplier

The Plunger Retainer WS1025 is a precision-engineered component designed for high-pressure Waterjet Intensifier Pumps, responsible for securely holding and aligning the high-pressure plunger within the hydraulic piston assembly. This retainer ensures proper axial alignment, stable reciprocating motion, and leak-free operation during pressure cycles reaching up to 94,000 psi (6,480 bar).

Manufactured from hardened stainless steel or nickel-chrome alloy, the WS1025 plunger retainer delivers exceptional mechanical strength, fatigue resistance, and corrosion protection. Each piece is CNC-machined to tight tolerances, providing a perfect fit with the plunger rod, piston, and seal assembly. Its precision threading and polished contact surfaces minimize friction, prevent vibration loosening, and help maintain consistent hydraulic pressure throughout long operating hours.

The Plunger Retainer WS1025 is compatible with all major waterjet brands, including KMT, FLOW, OMAX, WSI, BFT, and BHDT, making it an ideal OEM replacement for both preventive maintenance and complete intensifier rebuilds. When paired with components such as the Hydraulic Piston WS1031, Piston Seal WS1027, and High Pressure Seal Kit WS1020, it forms part of a reliable, high-efficiency intensifier system designed for continuous industrial use.
