RHA Insert Rod Pump Introduction:
Our RHA insert rod pump is a common mechanical oil production pump used in oil wells. Installed within the tubing string of an oil well, RHA insert rod pump primarily relies on the up-and-down motion of the sucker rod to drive the plunger, thereby lifting well fluid. The performance and technical requirements of our RHA insert rod pumps comply with API standards and GB/T18607-2008.
RHA Insert Rod Pump Model Explanation:
R → Rod Pump.
H → Heavy Wall Barrel, suitable for highly abrasive and high-pressure well conditions.
A → Top Anchor, meaning the pump is secured to the tubing via its top anchor.
Thus, the RHA is an insert pump for oil wellsp consisting of a fixed barrel, a thick-walled pump barrel, and a top anchor.

FAQ of API Insert Pump:
Q: What are the main differences between the RHA insert rod pump and the RWA API insert pump?
A: The RHA insert rod pump has a thick-walled barrel, capable of withstanding higher pressures and suitable for medium-depth wells and wells containing sand. The RWA API insert pump has a thin-walled barrel and is primarily used in shallow wells.
Q: How should I choose a base for my downhole rod pump?
A: Mechanical bases are suitable for high-temperature environments and require less frequent maintenance. Cup-type bases are easy to install but require replacement each time the pump is disassembled.
Q: Can the material of our insert pump for oil wells be customized?
A: Yes, we offer custom insert pump for oil wells with chrome plating, carbide coating, and special alloy steel options to suit different well conditions.
