Raw materials in the sealing industry refer to materials that can withstand gap displacement to achieve airtightness and watertightness and are buried in building gaps, referred to as sealing materials.
There are two types of water pump seals, namely packing or mechanical seals. The sealing material is selected according to the actual needs of the working conditions. Generally, packing seals are selected. Common materials include carbon fiber, ramie fiber, and aramid fiber
Each mechanical seal can only function effectively within the specified range. Improper selection will significantly reduce sealing performance, shorten service life, or even cause failure.
The material selection of mechanical seals depends on the specific use conditions and performance requirements. The following are several common mechanical seal materials:
The properties of commonly used materials are as follows:
For critical applications, particularly in regulated industries or environments where performance is non-negotiable, OEM seals offer a level of assurance that aftermarket alternatives may not match.
