HG Pump Information
Portal Service distributes, delivers, installs and maintains HG Pumping Units in the United States. We currently have new and used HG units ranging in size from 80 to 1280 in stock. Units are available for quick delivery and installation. We also carry pumping unit engines, pads and weights.
HG Curved Walking Beam Pumping Units are a major innovation in energy efficient pump jack technology. With over 12,000 units operating globally, Portal Service carries HG 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.
How does it work?
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 (patent pending). The dynamic structure imbalance provided by the beam weights allows the counterweights to benefit the gearbox torque when it's needed most.
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 conventional pumping unit, the crank weight and the motor do all the work. With the HG pumping unit, the curved walking beam places the beam weight at the furthest distance from the samson post to provide maximum leverage. This helps the crank 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 conventional pumping unit, the weight of the rod string pulls the crank weight back up, usually resulting in negative torque on the motor with the HG pumping unit, the beam weight is at a minimum 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 the HG Curved Walking Beam Pump Unit requires a less powerful motor and roughly 20% less energy consumption. These savings can result in increased profits immediately.
