End Bell Snap Ring 1-12370 Water Jet Pump Replacement Parts

The end cap retaining ring, model 1-12370, is a critical fastening component in Waterjet Booster Pump systems. Its primary function is to securely lock and position the end cap and associated internal components, thereby preventing movement, loosening, or displacement during high-pressure operation.
This retaining ring helps maintain the correct structural alignment of the pressure-boosting components, ensuring stable pump system performance and protecting the system from mechanical failures caused by vibration, pressure loads, and repeated operation.
Although the end cap retaining ring is small in size, it plays a crucial role in ensuring the long-term, safe, and reliable operation of the WaterJet Pump System.

Is the End Cap Retaining Ring 1-12370 considered a wear part?

Yes—End Cap Retaining Ring 1-12370 is classified as a “semi-wear part.”
Although it does not wear out as quickly as seals or pistons, under continuous pressure loads, vibration, repeated disassembly and reassembly, and mechanical stress, it may gradually deform, lose strength, lose its clamping force, or even become damaged.
It is recommended to inspect this component regularly during routine maintenance; if wear or deformation is detected, it should be replaced immediately.
