Product description
The applicable tubing pump is larger in size than rod pump in the same tubing. Tubing pump has simple structure so the displacement is bigger and it is suitable for the shallower well with shallow depth and high production.
The tubing pump means that its standing valve is directly connected to the barrel and it cannot be pulled up separately with the barrel. The THC or THM type of tubing pump means that its standing valve can be pulled up separately with the barrel. The seating assembly of THC pump is cup type and for THM is mechanical type.

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 problem,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
