Expanding possibilities ™
The new Centrilift FLEXPump series multistage centrifugal pumps have the industry’s highest efficiency and widest operating range, providing the operational flexibility required in dynamic well conditions. The advanced-engineering hydraulic designs of the pump stages maximize production while extending electrical submersible pumping (ESP) system run life. The 400FLEXPump17.5 pump, a model in the FLEXPump family, is designed for flow rates from 500 to 2,600 B/D.
Improving efficiency and reliability with ATM design The 400FLEXPump17.5 pump’s mixed-flow design features a patent-pending advanced turbulence mitigation (ATM) technology to increase efficiency and reduce gas locking. The
ATM design helps prevent plugging from solids and reduces the erosive wear caused by abrasive fluids to improve ESP system uptime and overall run life. The particle swirl suppression ribs in the diffuser provide further abrasion resistance by reducing the buildup of abrasives that can cause erosive wear and the potential for housing perforation down hole. The FLEXPump series pumps incorporate innovative hydraulic design concepts to expand the application range of ESP systems. The 400FLEXPump17.5 pump expands the ESP system’s optional flexibility for the duration of the well’s production cycle and operates more efficiently in a wider flow range to reduce operating costs, improve reliability, and optimize production in changing downhole conditions.
– Adaptable to changing well conditions – Enhances reliability – Reduces pulling costs Improved hydraulic thrust balancing – Increases reliability Mixed-flow design – Improves gas handling – Increases ESP uptime and production by reducing gas locking and well cycling

The 400FLEXPump17.5 pump’s improved hydraulic design increases total system efficiency. This efficiency improvement increases ESP system uptime while lowering power costs. The hydraulic balance of the stages reduces thrust wear as the pump expands the edges of the recommended operating range. This results in higher reliability, less stress on the system, and longer operating life. The wider operating range of the 400FLEXPump17.5 pump enhances ESP system adaptability as the well’s production index changes. The mixed-flow design allows gas to

pass more easily through the pump compared to a radial-flow stage, mitigating gas locking and well cycling conditions that can cause electrical shorts and other issues that can reduce ESP system run life. The 400FLEXPump17.5 pump still maintains a steep head curve toward shut-in on the performance curve. This provides for better gas handling and reduces pump off conditions. A steeper head slope to the left helps to compress
