The effi cient, reliable Centrilift FLEX™

series electrical submersible pumps (ESP) have the industry’s widest operating range, providing operators with the operational fl exibility required in dynamic well conditions to minimize ESP system change outs and nonproductive time while at the same time reducing operating expenses. The high-performance FLEX series pumps are specifi cally designed to maximize production and ultimate reserve recovery from conventional oil fi elds, low-fl ow rate mature oil fi elds, and unconventional resource plays in which the production index declines rapidly.

Expand the operational fl exibility of your ESP systemThe FLEX pump designs reduce the total hydraulic thrust in both upthrust and

downthrust conditions, allowing the pumps to operate effi ciently and reliably in a wider operating range.

The extended operating ranges of these pumps mean the ESP system is adaptable to changing well conditions as production rates change. FLEX pumps provide operational fl exibility over radial compression stages and deliver extensive fl ow ranges from a minimal number of pump models in the FLEX series. Flow rates range from 50 to 10,500 B/D.

The FLEX line expands the application range of ESP systems and Baker Hughes application engineers choose the right FLEX pump for each well’s specifi c requirements, focusing on what’s most critical to maximize the return on investment from every well.

Centrilift FLEX Series Pumps Improve ESP operational fl exibility and performance in dynamic well conditions

Enhance the effi ciency of your ESP systemBaker Hughes engineers designed the FLEX series pumps to deliver superior effi ciency across the wider operating range, lowering OPEX—including power consumption—over the life of the well.

The FLEX pumps deliver continuously rising lift per stage, allowing for better well drawdown, higher effi ciency, and improved uptime by reducing cyclic shut downs. This also lowers the motor operating temperature for increased run life and superior overall system effi ciency. Greater effi ciency gives you an OPEX advantage over the life of the reservoir.

Improve the reliability of your ESP systemFrom existing assets and new production zones like shale resource plays, tight reservoirs, and deeper zones, where fl ow conditions can change dramatically over short periods of time, the FLEX series of pumps improves reliability by providing a pump that can deliver stable operation in varying conditions. The FLEX series pumps can handle thrust conditions more effectively than legacy pump models, which increases run life, reduces workovers, and decreases downtime.

Wider stage vane openings reduce pump plugging and give ESP systems enhanced solids and gas-handling capabilities. Lower hydraulic thrust extends operation in lower fl ow conditions and heavier construction of FLEX pump components increases uptime and reliability.
