Double-horse head Pumping Unit
It is an energy saving product that has a long stroke and low SPM .
It is used for pumping oil of middle and high viscosity and high water content.
As compared with the same model of conventional pumping unit, it increases the stroke length by about 70%, reduces energy consumption by 20-30% and decreases unit installed capacity by about 50%.
It was taken as a stressed spreading project by CNPC in 1994 and a nationally stressed spreading project in 1995.
