Auto coupling
Auto coupling for non-insert SRP pumps
Description
The auto coupling is designed for automatic coupling of the sucker-rod string with the plunger stem of a non-insert rod pump after running the pump assembly into the well. It is used in rod-pumping oil wells equipped with non-insert SRP pumps and enables running non-insert pumps assembled with the plunger.
