The efficient, reliable Centrilift FLEX™ series electrical submersible pumps (ESP) have the industry’s widest operating range, providing operators with the operational flexibility 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 specifically designed to maximize production and ultimate reserve recovery from conventional oil fields, low-flow rate mature oil fields, and unconventional resource plays in which the production index declines rapidly.
Expand the operational flexibility of your ESP system The FLEX pump designs reduce the total hydraulic thrust in both upthrust and
downthrust conditions, allowing the pumps to operate efficiently 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 flexibility over radial compression stages and deliver extensive flow 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 specific requirements, focusing on what’s most critical to maximize the return on investment from every well.
Lower
hydraulic thrust
– Extends operating range Heavier
wall construction in pump components
– Extends pump run life Enhanced
ESP system efficiency
– Lowers OPEX – Reduces power costs
Enhance the efficiency of your ESP system Baker Hughes engineers designed the FLEX series pumps to deliver superior efficiency 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 efficiency, and improved uptime by reducing cyclic shut downs. This also lowers the motor operating temperature for increased run life and superior overall system efficiency. Greater efficiency gives you an OPEX advantage over the life of the reservoir.
Improve the reliability of your ESP system From existing assets and new production zones like shale resource plays, tight reservoirs, and deeper zones, where flow 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 flow conditions and heavier construction of FLEX pump components increases uptime and reliability.
