Guide Bushing 1-12974 Waterjet Pump End Bell Parts Price

Guide Sleeve 1-12974 is a critical support and positioning component in Waterjet Booster Pump systems. Its primary function is to guide and stabilize the operation of the piston rod, plunger, or other reciprocating components, thereby ensuring precise alignment of all parts during high-pressure operations and reducing the occurrence of abnormal wear.
This component helps maintain smooth operation between moving parts, protects seals from damage caused by uneven friction, and enhances the overall stability of the entire hydraulic and high-pressure system.
For extending component service life, maintaining sealing performance, and ensuring the long-term reliability of the pump, a precision-manufactured guide bushing is an indispensable key component.

Is Guide Sleeve 1-12974 considered a wear part?

Yes—Guide Sleeve 1-12974 is classified as a “semi-wear part.”
Although it is more durable than seals and O-rings, it is constantly subjected to friction, vibration, reciprocating motion, and pressure loads. Over time, this component may experience internal wear, surface damage, deformation, or a decline in guiding accuracy.
It is recommended to inspect this component regularly during routine maintenance; once signs of wear are detected, it should be replaced promptly to effectively protect other associated components from damage.
