HP Spring 500-20-0112 Good Quality WaterJet Pump Parts For Sale

The HP Spring 500-20-0112 is a precision-engineered high-pressure compression spring specifically designed for waterjet intensifiers and ultra-high-pressure outlet check valve assemblies. Its primary function is to provide accurate, consistent return force for the HP Outlet Poppet (500-20-0110), ensuring reliable valve seating, smooth fluid flow, and leak-free sealing during each intensifier stroke.

Manufactured from premium spring-grade stainless steel or nickel-alloy steel, the 500-20-0112 spring offers excellent fatigue resistance, elastic stability, and corrosion protection, even in continuous operation at pressures up to 60,000 psi (4000 bar). Each spring is CNC-coiled, heat-treated, and stress-relieved to maintain precise load characteristics, guaranteeing long service life and consistent valve response in high-pressure environments.

The HP Spring 500-20-0112 is fully compatible with major waterjet system brands including KUNDA, KMT, FLOW, and OMAX, and works in perfect coordination with the HP Outlet Poppet Kit (500-20-0110) and HP Check Valve Seat (500-20-0111). Together, these components form the core of the high-pressure outlet assembly, delivering reliable pressure retention and consistent cutting performance.

Engineered for high-frequency operation and extreme durability, this spring is essential for maintaining system stability, efficient check valve function, and cutting accuracy in demanding industrial waterjet applications such as metal fabrication, stone cutting, ceramic processing, and composite manufacturing.
