Special seals Cartridge design - the modern alternative
Cartridge type mechanical seals are independent units, consisting of a shaft sleeve, mechanical seal and flange. It is mounted on the pump shaft in the assembled state, and further assembly is not necessary. Thus it is ensured that the different parts won’t be assembled wrong, the springs are correctly loaded and friction surfaces are not contaminated .
