Our electric submersible pump (ESP) systems are multistage centrifugal pumps. Each stage consists of a rotating impeller and a stationary diffuser. Designed to effectively handle production rates from 200 to 95,000 bbl/d with boost pressures of up to 6,000 psi, our ESPs are subject to a multitude of applications. In addition to typical oil, water, and brine production, they are used for booster service, ballast transfer, waterfloods, direct injection, cavern storage, mine dewatering, fire protection, irrigation, and commercial water systems.
To maintain optimum performance within corrosive or abrasive wells, the systems’ stage materials are constructed from MONEL alloy shafts, which are standard on all pumps. Optional high-strength shaft material is also available. The patented ARZ abrasion-resistant zirconia bearings and compression-ring construction are the most technologically advanced submersible pumps available. These pumps are used for abrasive applications where maximum reliability is required. The compliant-mounted zirconia bearings have repeatedly shown 100 times less wear than hardened alloy bearings in tests and actual field performance.
