Spring 1-18748 Waterjet Cutting Machine Parts Supplier

The Model 1-18748 spring is a critical internal component in Waterjet Booster Pump systems. Its primary function is to provide stable spring force for valve operation, seal support, and pressure control, thereby ensuring smooth movement and reliable performance of the high-pressure pump assembly.
This spring is commonly used in check valve assemblies, inlet and outlet lift valve systems, relief valves, and pilot valve control systems, and is suitable for applications that demand extremely high precision in force application and reliability in reciprocating motion. It helps maintain normal valve opening and closing operations, enhances sealing performance, and improves the overall operational stability of the system.
Selecting a high-quality spring is crucial for achieving stable pressure control and ensuring the long-term reliable operation of the pump.

Is the 1-18748 spring a wear part?

Yes—the 1-18748 spring is a typical wear part.
Because this spring is constantly subjected to sustained pressure, repetitive motion, high-pressure cyclic shocks, and mechanical stress, its elasticity may gradually diminish over time, leading to reduced strength and even deformation or breakage.
Failure to replace it in a timely manner may result in a series of failures, including pressure fluctuations, valve failure, media backflow, leakage, and reduced cutting performance.
Therefore, we strongly recommend that you inspect this component regularly and replace it according to a scheduled maintenance plan.
