Problems with the inlet and outlet of shielded pumps

It’s probably serving as a buffer! It’s not very clear what the difference is between upper eccentricity and lower eccentricity
For horizontally suction centrifugal pumps, when the inlet pipe changes diameter, an eccentric reducer should be installed near the pump’s inlet. When the pipeline feeds into the pump from below, horizontal installation at the top should be used; when it feeds from above, horizontal installation at the bottom is preferable, in order to remove air from the pump inlet.

Personally, I think it’s better to have eccentricity when setting the level; the guy on the 3rd floor gave a great answer. In fact, if you use level adjustment, the source will definitely be either above or below as well
If installed horizontally, it should also be mounted at a horizontal level
