why we need welded type wave spring for cartridge mechanical seal?

in many case for cartridge mechanical seal, we need wave spring for it, but many times, wave spring also brings some problem when mechanical seal running.

like wave spring broken, leakage, and sliding when running,  so how to solve this problem?

" welded the wave spring for the mechanical seal."  idea from Mr. YUE,  the senior engineer from lepu seal factory, making and repairing the mechanical seal for more than 20 years. welded the end of the wave spring offer more strong support when mechanical seal running, and avoid the sliding. as the picture shows.

lepu seal make mechanical seal since 1998, and solve many similar problems, we find some problmes come from the wave spring, and now we suggest the user to choose welded type wave spring.

the below picture show the difference to you.
