Are there any coupling (3- jaw coupling) on this pump-motor?

Mr Onur, 

 

Yes,  the coupling is jaw coupling.  But i can't remember the number of jaw. I will check it when I back on the field. 

Do you think that there is a possibility that 3x caused by the coupling (if the coupling is 3 jaw coupling) ?
