Product Outline

The API C series pumping unit is one kind of convention beam pumping unit, which selects the crank balanced method. It is the most common, an application scope broadest surface power equipment in field production oil .

The products conform to API Spec 11E " Specification for Pumping Units " and other related standards, and have obtained the certificate of authority to use the official API monogram.

Technical Features

1. Carry out the design using the modulation and the hypothesized technique of manufacture, optimize the product structure pattern, the spare parts have high level of “the standardization, the universalization, the seriation”. 

2. Strength of key parts is calculated with the finite element analysis， the property is stable, the reliability is high.

3. The structure is reasonable, work smooth, low noise, the operation maintenance is convenient.

4. In the reducer use the symmetrical divergence type double circular arc or the involute double helical gear transmission, its seal is good, the noise is low, the revolution is steady, it is reliable and durable. 

5. The beam is H-beam steel structure, which has high strength, good rigidity, large carrying capacity. 

6. The horse head is hanging structure, when carrying out workover, the horse head will be unloaded off .

7. Support is a three-legged structure, convenient in installation, simple operation.
