Product Overview

The rod-type sucker pump is fixed and sealed with the sucker rod into the predetermined position in the tubing, so it is also called "insertion pump". It does not need to lift the tubing when checking the pump. It is convenient for operation and suitable for use in deep wells. ; Reduce the operation of the upper shackle of the oil pipe and extend the service life of the oil pipe; the pump body of the rod-type oil pump can swing around the fixing device, which is suitable for inclined wells.y.

The plunger surface of the rod pump is spray-welded nickel-based alloy, the inner bore of the pump barrel is nickel-plated phosphorus or carbonitriding, valve ball, Balls and other key parts are made of special corrosion-resistant materials, and are subjected to strict heat treatment and precision mechanical processing.

Working principle

Our rod pump is equipped with a cup seating nipple N11, cup seating nipple N11 connection on the tubing string, down to the bottom of the well with the tubing string. Plunger assembly connection on the sucker rod string and with the pump overall down to cup seating nipple N11 position together , pump with fixed inside the cup seating nipple N11, Plunger assembly with the sucker rod string up and down reciprocating movement to achieve pumping work.

How to Use Sucker Rod Pump?

• Before leaving the pump, you must check the factory mark and certificate on the pump. Confirm that it is the oil pump required for this oil well, and carefully check whether the pump barrel is bent, whether the exposed threads are damaged or corroded, and whether the connection parts of each thread are loose.
• The well site where the pump is to be pumped must be kept clean and tidy to prevent sand or other things from falling into the well and affecting the normal pumping of the pump. A final inspection should be performed when lowering the pump. To ensure that the protective cap, plug and protective entanglement are all removed.
• For the oil pump that has been in stock for more than one year, the plunger and pump barrel should be cleaned before going down the well, and the plunger should be pulled back and forth.
