API 11AX Oilfield Sucker Rod Pump1

API standard oilfield tubing pump Product description: In the rod - having pump operation, API standard subsurface sucker rod pump is one quite important downhole oil production equipment. which can be divided into tubing pump and rod pump.

Specification table:

 operating principle of tubing pumps:The pump barrel assembly directly fixed on a tubing string. the plunger assembly connected on the sucker rod string ,and with the up and down reciprocating motion, so as to realize the production process. Its advantage lies in: in the process of oil production, when the traveling valve and fixed valve side problems arise,valve side can be proposed by the sucker rod, piston and extractor , don’t put the whole pump and tubing string out of the well, reduce the work intensity and the operation cost.
