How to position a double-end face seal on a shaft sleeve
There are three forms of two-sided configuration: series, back-to-back, and face-to-face. It’s obvious just by looking at this sealed sample
Find a sealed sample and you’ll know right away
May I ask, what distance should be set between the sealing surface in the direction of the impeller and the edge of the shaft sleeve?
You know the working height of the seal, right? You also know the fixing position of the shaft sleeve; just measure it with a depth gauge and do the calculation
What is commonly seen is the set screw pressing radially against the shaft to serve a positioning function

There are various types of positioning mechanisms; the modular type is already designed, and some shaft sleeves are equipped with positioning platforms； The double-end mechanical seal of bulk high-speed pumps is primarily positioned by the length of the shaft sleeve, which is also predetermined; it can also be adjusted by machining the entire assembly to varying lengths
