Conventional beam pumping units remain one of the most reliable and widely used artificial lift methods in the industry, and Liberty Lift has built its reputation on doing them right. Our engineering team has decades of hands-on experience designing, manufacturing and supporting beam pumping units across North America.
Liberty Lift offers two conventional unit configurations, the High Efficiency (HE) and the Enhanced Geometry (EG), engineered to maximize upstroke performance, protect the rod string and operate reliably at low speeds. Both are manufactured in our most popular sizes as well as additional sizes to fit specific well requirements, and exceed API 11E specifications, backed by an integrated quality process from foundry to field.
From fabrication to final assembly and testing, every unit is inspected and verified before it ships, so installation goes smoothly and performance starts on day one.
Liberty Lift HE units are available in the following configurations. Spec sheets are available for download below.
