Conventional light API B pump units, balanced by walking beams, are among the most common and most widely used power units in rod production on oil fields. Products comply with Specifications of Pumping Units (API Spec 11E) and other related standards, and have acquired the authorization to use Official API Monogram.
Characteristics:
2. Reducers are driven by involute or double-arc herringbone wheels and thus can operate stably and reliably.
3. The entire machine is very light and thus can be installed and transported conveniently.
4. It is applicable in shallow oil production with small stroke and light loads.
