Oil & Gas · Application
Pumpjack / Beam Pump
More than a million units installed worldwide — the most recognisable piece of surface production equipment in the industry, and one of the most demanding duty cycles a motor can be asked to run.
Motor Requirements
What the application demands
| Parameter | Typical Value |
|---|---|
| Power range | 15–150 kW, most commonly 25–75 kW |
| Voltage | 460 V / 575 V (North American NEMA) or 380 V / 660 V (IEC) |
| Machine type | NEMA Design A/C, TEFC totally enclosed fan-cooled |
| Operating mode | Continuous 24/7 with large load swings — 30–50% between upstroke and downstroke |
| Speed control | Variable-frequency drives increasingly replacing mechanical speed change |
What the Field Actually Says
Real problems on the lease
Downhole diagnosis is hard
Experienced field engineers frequently disagree on the root cause of high rod and coupling breaks, and the same well can suffer repeats within months.
The controller matters as much as the motor
Operator opinion on pump-off controllers is strongly divided, and the difference in day-to-day reliability is real. Specifying the control system deserves the same attention as specifying the machine it drives.
