API 11E C series of pumping units
Product overview of pump unit/pump jack: The API C series of oil pumping units is a widely used conventional
beam pumping unit that employs the crank balanced method. This
ground power device is extensively utilized in rod oil production.
The product complies with the specifications outlined in API Spec
11E for oil pumping units and meets other applicable industry
standards. It has also obtained the API monogram license.
Technology characteristics of pump unit/pump jack:
1.The using of modular design and virtual manufacturing technology
to make product structure optimizated and parts with high degree of
"standardization, generalization, seriation" .
2.Studying on finite element analysis of key structure with stable
performance and high reliability.
3. The speed reducer adopts symmetrical shunt type involute or
double circular-arc herringbone gear transmission, with good
sealing, low noise, stable operation, reliable and durable.
4. the operation is simple, easy maintenance and long service life.
CYJ series of pumping units
Product overview of CYJ series pump unit/pump jack: The CYJ series of oil pumping units is a widely used type of
conventional beam pumping unit in the field of rod oil production.
It complies with various industry standards such as API Spec 11E
pumping unit specification, SY/T5044-2003 beam pumping unit, and
other relevant standards. The product has obtained an API monogram
using license, indicating its quality and adherence to industry
standards. In addition to the production of conventional beam
pumping units, we have also developed phase balance beam pumping
units, interference-reducing beam pumping units, and other
