Paper: Applications of Air Balanced Pumping Units

For most wells that have to be pumped, the conventional crank-type beam pumping unit meets all specifications and is lower in price and maintenance costs. However, in recent years a new unit has become increasingly popular because it has some advantages over the conventional unit. This is the Air Balanced Beam Pumping Unit, which differs from the conventional unit in that compressed air is used as a means of counter-balancing the load on the polished rod. In other respects the air balanced unit resembles the conventional unit in that it employs a speed reducer, cranks, pitman's, beam and Samson post as used for many years on conventional units.
