Tower-type Long Stroke Energy Conservation Pumping Unit is a kind of conventional walking beam pumping unit widely used.

Tower-type Long Stroke Energy Conservation Pumping Unit 

Standard: API Spec 11E 

Limited interial load and dynamic load of unit, rod and pump can effectively reduce friction between sucker rod and tubing, so as to get a long maintenance-free period of wells. In both high work efficiency and multi-protection functions, this unit not only has energy-saving rate of above 40.64%, comparing with traditional pumping unit.
