Downward Barbell Pumping Units details

---

Main features:
·The downward barbell is used to balance and lessen down the peak torque.
·The position and weight of the downward barbell can be reasonably set according todifferent well conditions.
·This type of pumping unit has all advantages of conventional ones, has good balance effect and reliable performance.
·Compared to the conventional beam pumping unit, it can save energy by more than 20%.
·Accordance with API SPEC 11E standard, and have the certificate of authority to use the official API monogram.

Moment Adjustable Pumping Unit
Main features:
·Offset balance structure is adopted for the walking beam.
·Adjustment can be carried out simply. The counter balance weight is near the ground when the horse head is at its highest position, thus medium and small balance weights can be added to or removed from it easily.
·Good balance performance. Balance can be accurately adjusted according to peak load position.
·The walking beam and the Sampson post should be locked when adjusting the stroke length, so as to increase operation safety, lowering down labor intensity and crane engagement.
·The medium and small size pumping unit will adopt rear adjusted structure while the large sized ones will adopt front adjusted structure .
·Accordance with API SPEC 11E standard, and have the certificate of authority to use the official API monogram.
