The 400FLEX31 pump, a model in the new Centrilift FLEX™ series of multistage centrifugal electrical submersible pumps, delivers unmatched performance for flow rates from 4,000 B/D to as low as 1,200 B/D. This hydraulically proficient mixed-flow design lowers the horsepower requirement over the entire flow range, producing higher efficiency than pumps from previous pumping systems.
Innovations
Expanding possibilities
Mixed-flow stages, which have wider vane openings, improve the dependability of the pumps when solids are entrained in the production stream. For abrasive or scale-prone applications, the FLEX series of pumps are available in Stabilized Normal Duty (SND), Stabilized Severe Duty (SSD), and Stabilized Xtreme Duty (SXD) configurations.
The FLEX series pumps have the industry’s highest efficiency and widest operating range, providing operators with the operational flexibility required in dynamic well conditions. The advanced-engineering hydraulic designs of the FLEX pump stages maximize production while extending electrical submersible pumping (ESP) system run life.
The design of the 400FLEX31 pump was developed using Computational Fluid Dynamic (CFD) simulation software. The simulation work resulted in patentpending design concepts, which reduce the thrust profile throughout the pump. As a result, the 400FLEX31 has an operating range from 1,200 to 4,000 B/D, the widest in the industry at this flow rate.
