Detailed Product Description

pumping unit ,

Features: 

      Better balance effect makes torque fluctuation of reducer more gently, improves the working condition of reducer, increase capacity and prolongs service life.  

      An optimized four-bar linkage provides a greater rotation angle (192°) of upstroke than that (168°) of downstoke to decrease dynamic coefficient and increase load capacity. 

      Smaller motor can be selected compared with conventional unit. If the eccentric angle is designed as adjustable, the power-saving ranges can be applicable up to 20-30% to different well conditions.
