The API Tubing Pump offers enhanced performance in terms of corrosion resistance and antifriction compared to conventional tubing pumps. The plunger of the API Tubing Pump is nickel-plated on an alloy base, while the inside wall of the barrel is coated with hard cadmium. Key components such as the valve hood and Valve Ball are made from materials known for their excellent mechanical performance and corrosion resistance.

As a result of these improvements, the API Tubing Pump boasts a longer working life when compared to conventional pumps. This increased durability ensures reliable and efficient operation over an extended period of time.

The Rod Pump is assembled on the surface and then connected to the Sucker Rod. It is then lowered to the bottom of the well through the tubing. This assembly method offers convenient inspection and workover processes, as the rod pump can be easily pulled up and down through the tubing. This feature makes it particularly suitable for deeper wells.

Using a rod pump helps prolong the lifespan of the tubing. By reducing the frequency of turning the tubing's threads on and off and minimizing the need for workovers, the wear and tear on the tubing is reduced.

The rod pump can be classified into two types: mechanical seating and cup seating. Additionally, it is further divided into three types: RHA (stationary heavy well barrel top anchor rod pump), RHB (stationary heavy well barrel bottom anchor rod pump), and RHT (traveling heavy well barrel bottom anchor rod pump). These classifications help differentiate and specify the various configurations and functions of rod pumps.
