In the field of petroleum extraction, the rod pump oil recovery system has become the most widely used manual lifting method due to its high adaptability, simple structure and easy maintenance. As the core equipment of the system, API tubing pump occupies an important position.

In the previous article, we discussed the RHA Insert Rod Pump. This article will explain the definition, model description, technical specifications, structural components, operating principle, application scenarios, comparison with other pump types, and installation methods of the TH tubing pump.

In many oilfields, especially unconventional resource wells, traditional lifting equipment is prone to the following problems: Short lifespan: Sandy or corrosive well fluids cause rapid wear of the pump body; Frequent maintenance: Frequent well shutdowns for inspections lead to reduced production; High labor dependency: Experienced technicians are required to maintain operation. These pain points are driving more and more buyers in 2025 to seek solutions that reduce O&M costs while ensuring long-term stable operation. Table of Contents: Why choose an API tubing pump?

For this reason, "how to efficiently and economically clean oil well pumps" has become a crucial concern for oil production plants, service companies, and even every on-site worker. Drawing on field experience and industry practices, we have compared and summarized the cleaning methods for API rod pumps and API tubing pumps.

The production of a well often depends not only on the oil supply capacity of the oil layer itself, but also on the performance of the pump efficiency. The pump efficiency directly determines whether the unit energy consumption can be converted into more crude oil output. There are many factors that affect the API tubing pump efficiency, but from the three basic links of deep well pump operation (piston volume, crude oil entering the pump and crude oil being discharged from the pump), it can be summarized into the following three aspects.

1. API Tubing Pump Definition and Principle: API tubing pump: The pump barrel is fixed to the lower end of the tubing, and the sucker rod drives the plunger back and forth to achieve suction and discharge. Compared to insert pumps (in which the pump barrel and plunger can be pulled and retracted as a single unit), API tubing pumps have thicker barrels, are more pressure-resistant, and more wear-resistant. However, this comes at the cost of requiring the tubing to be pulled for maintenance, making them less accessible.

Designed in strict compliance with API 11AX standards, API tubing pumps utilize a one-piece rough barrel and precision grinding to ensure a precise fit with the plunger. They utilize high-strength construction, wear-resistant alloy materials, and modular wear parts.

API type tubing pumps and API type rod pump​s are two common types of mechanical oil production equipment. Due to their structural differences, their application performance in different well conditions varies. Choosing the right pump based on well depth, production rate, and ease of maintenance has always been a core concern for oilfield engineers and production units. This article will provide an in-depth analysis of the structural characteristics and application scenarios of API type tubing pumps and API type rod pumps, helping you quickly compare their advantages and limitations.

The main difference between tubing pumps and insert rod pumps is that tubing pumps have a simple structure and low cost. The diameter of the pump that can be inserted under the same oil pipe diameter is larger than that of insert rod pumps, so the displacement is large. However, when inspecting the pump, the oil pipe must be started, and the workload of repairing the well is large. It is suitable for oil wells with small depth and high production. Insert rod pumps are convenient for pump inspection, but have a complex structure and high manufacturing cost. The diameter of the pump that can be inserted under the same oil pipe diameter is smaller than that of tubing pumps. Insert rod pumps are suitable for oil wells with large depth and low production.

Tubing pump, also known as tubing pump, is divided into double-valve and three-valve tubing pump according to the number of valves. It consists of a working cylinder, a piston, a floating valve, a fixed valve, etc.:
