What types of couplings are these?
Isn’t this just an ordinary elastic pin coupling? The first one seems to have an extended shaft
The second one is a pin, and the third one is a three-claw
The first one can be considered a protective cover for the shaft; it can’t be a coupling. There are many ways to connect shafts; this might be a toothed plug-type coupling method.
The first one has bolts that resemble those of a diaphragm coupling
In order, they are elongated diaphragm couplings, pin-type couplings, and claw couplings

Hello, building management! The three images show: 1. Elastic diaphragm coupling, 2. Pin-type coupling, 3. Claw-type coupling. I hope this can help you. If you have any issues with the pump, feel free to contact me at any time. My phone number: 13313170275 (same number on WeChat)
