Rod oil pump

The rod oil pump can be fixed and sealed as a whole at
the predetermined position when the sucker rod is lowered
into the tubing, so it is also called "plug-in oil well pump".
The rod type oil well pump does not need to trip the tubing
during the operation of lifting and lowering the oil well
pump, which is convenient, time-saving and labor-saving,
and takes up a short time in the well; at the same time, it
reduces the screwing up and unloading operation of the oil
pipe, reduces the potential leakage of the oil pipe thread,
extends the service life of the oil pipe, and is good for the
maintenance of the oil pipe.
