Seal Carrier Assembly 1-18875 New Good Price Waterjet Parts Supplier

The 1-18875 seal seat assembly is a critical sealing support component in a Waterjet Booster Pump system. Its primary function is to support, position, and protect the high-pressure seals inside the pump assembly, thereby ensuring stable sealing performance and reliable ultra-high-pressure operation.

This assembly works in conjunction with the plunger, high-pressure cylinder, and spare seals to maintain proper seal alignment, reduce the risk of leakage, and enhance the overall durability of the entire sealing system.

A high-quality seal seat assembly helps extend the service life of the seals, maintain stable cutting pressure, and prevent the booster pump from failing due to premature wear.

Is the 1-18875 seal seat assembly a wear part?

Yes—the 1-18875 seal seat assembly is considered a “semi-wear part.”

Although its service life is longer than that of the seal and O-ring, it is constantly subjected to high pressure, friction, repeated maintenance and disassembly, and mechanical stress. Over time, the assembly may experience wear, deformation, damage to the sealing surfaces, or thread wear.

It is recommended to inspect this assembly regularly during pump maintenance; if signs of wear are detected, it should be replaced promptly.
