How should the angular contact bearings of vertical submersible pumps be installed?

2018-06-26View Original

Thread Content

The impeller end, that is, the end submerged in water, has only one graphite bearing. The coupling end, or the upper end, has two angular contact bearings 7309; furthermore, the shaft is equipped with locking wires, and it is supported by these two bearings, otherwise it would fall down. Normally, the shaft of an AY pump is horizontal, and the angular contact bearings are installed back to back. If the vertical pump also has its bearings installed back to back, then wouldn’t the 7309 bearing below be under excessive stress? The manufacturer is also unsure about how to install it; someone with expertise please help
