Consultation on diaphragm pump disassembly

To disassemble the motor part of this pump, one simply loosens the screw in the middle; by giving the copper rod a gentle shake, the motor can be separated. But will the impeller and shaft at the pump end move towards the pump casing and rub against it?
No, it either has its own axial positioning or relies on the motor shaft for positioning; once the motor is installed, its position is determined
Where are the pictures? The problem isn’t clearly stated at all
Could you provide an image? It might be a tapered fit in the middle
The diaphragm pump motor is connected to a worm gear – how could it be an impeller? The two ends of the worm are positioned by bearings.
I’m adding the picture again – it disappeared right away when I posted it last time, and I don’t know why
