HG 1280-427-216 Pumping Units

A major innovation in energy efficient pump jack technology.

Free Oilfield Quote carries pumping units ranging in size from 80 to 1280 in stock.

With a combination of crank and beam based counterbalance weights, the HG curved Walking Beam Pumping Unit is engineered to provide a dynamic structural imbalance. This superior combination of counterbalances results in a considerable reduction in operation energy requirements, as well as reductions in net torque curve.

The HG Curved Walking Beam Pumping Unit uses two counterweights instead of one: the conventional crank weight and an adjustable beam weight positioned at the end of an engineered curved walking beam. The dynamic structure imbalance provided by the beam weights allows the counterweights to benefit the gearbox torque when it’s needed most.

How does it work?

At the beginning of the upstroke, when the horsehead is down, the motor and the counterweights have to do the most work to bring the rod and fluid up.

With the HG pumping unit, the crank weight and motor do all the work. The curved walking beam places the beam weight at the furthest distance from the samson post to provide maximum leverage. This helps the weight and the motor in bringing the horsehead back up.

At the end of the upstroke, when the horsehead is up, the motor and conventional weight do the least amount of work. The weight of the rod string takes the horsehead back down.

With the HG pumping unit, the weight of the rod string pulls the crank weight back up, usually resulting in negative torque on the motor. The beam weight is at a maximum distance from the samson post, resulting in less leverage to resist the horsehead’s fall.

And the result?

The combination of the two counterweights results in less motor torque during upstroke and reduces negative torque on the downstroke. Both theoretical calculations and actual field data have demonstrated the HG Curved Walking Beam Pump Unit requires a less powerful motor and roughly 20% less energy consumption.
