Everyone, take a look at what kind of coupling this is
Thread Content
On one of the submersible pumps in our company, the coupling connection part has worn out completely; now the two halves of the coupling are entirely separated. We plan to buy a new set, but we’re not sure what type of coupling it should be. Could everyone please help us figure this out?
Are there plum-blossom type interlocking couplings with fast elasticity? However, no elastic blocks were visible; it seems they have worn out. Given the degree of rusting and the broken parts, this problem must have been going on for some time – likely the elastic blocks wore out first, after which the wheels came into direct contact with each other, causing friction, and eventually leading to wear and damage on the wheels. In fact, this gear pair allows machining manufacturers to carry out surveying and manufacturing. It would be better if there is equipment documentation; it can be checked to confirm. The above is for reference only! If there are any mistakes, please point them out so we can discuss them together!

It’s a plum blossom pad three-pig coupling; measure the inner diameters of the motor side and the pump shaft, then go and ask the distributor. It should be a quite common type of component. Your on-site inspections are very inadequate – it seems no such inspections are carried out at all. The noise level is very high; it’s worn out to this extent
