FORLAND long-stroke vertical pumping unit 

Have you ever fix the flapping in the wind inherent in this design?

Try to have a pumper hump those counterweights for lower cost or roll back the unit without a roll back system.... ye right 😂

What the productivity range of this kind of pumps and what is the deepest point of the downhole pump?

Me parece que es un buen aparato , me gustaria saber del mantenimiento.-

Bad ad!! Sounds like it’s squeaking, needs greasing or about to crater! 👎👎👎

기름은 곳 고갈된다 고로 기름부국은 곳 망한다
