Guide Bush Assembly SP1120 WaterJet Pump Parts Supplier

The Guide Bush Assembly SP1120 is a critical precision component designed to stabilize and align the plunger or piston rod in high-pressure Waterjet Pumps and intensifier systems. It ensures smooth linear motion, minimizes wear on moving parts, and maintains perfect alignment under continuous high-pressure operation — a key factor in achieving consistent cutting performance and extending system life.

Manufactured from hardened stainless steel with precision-ground bores and high-performance polymer or bronze bushings, the SP1120 guide bush assembly provides excellent wear resistance, dimensional accuracy, and low friction operation. The internal surface is honed to perfection, reducing vibration and preventing premature seal wear during rapid reciprocating cycles.

The Guide Bush Assembly SP1120 is fully compatible with major waterjet brands such as KUNDA, KMT, FLOW, and OMAX, and can be installed directly into OEM or replacement intensifier units. This assembly supports the plunger, seal carrier, and high-pressure cylinder, ensuring smooth alignment and preventing side-loading that could otherwise lead to leaks or component failure.

Commonly used in metal cutting, stone processing, glass fabrication, and composite material machining, the SP1120 guide bush assembly is essential for maintaining system efficiency and pressure stability in high-demand industrial environments.
