Brand: Flowserve
Description:

The BF and BFD pump models are between bearings, axially split multistage pumps engineered for high-pressure fluid transport in power generation, pipeline, water injection, and boiler feed services. With a rugged construction and precision-balanced rotor assembly, these pumps are built to perform reliably under continuous-duty, high-head conditions.

Both models feature axially split casings that simplify inspection and maintenance, allowing quick access to internal components without disturbing pipe connections or motor alignment. The BF series is typically used for applications with lower flow but higher pressure, while the BFD model supports larger flow volumes with the same robust multistage design.

Manufactured to meet global standards including ISO and API equivalents, the BF and BFD pumps provide exceptional efficiency, low vibration, and high mechanical integrity across the most demanding industrial applications.

The BF and BFD are horizontal, axially split case, multistage centrifugal pumps adhering to ISO 13709/API 610 (BB1 and BB3) standards. Designed for medium to high flows, high heads and maximum efficiency, the single-suction BF and double-suction BFD are well suited for pipeline, refinery and waterflood services. Both configurations are available in 2-, 3- and 4-stage designs.

BF and BFD Between Bearings, Axially Split Multistage Pumps Applications

Crude, Product and CO2 Pipeline, Dewatering and Water Supply (mining), Distillation (oil and gas), Gas to Liquids, Heavy Oil, Oil Sands and Shale, Water Supply and Distribution (water)

  • Industries:
    Oil and Gas, Mining, Water Resources
  • Standards:
    API610

Suction and Discharge Nozzles are integrally cast with the lower casing, allowing disassembly and inspection of the rotating assembly without disturbing the piping.

Double or Staggered Single Volute Design balances radial loads on the shaft, minimizing shaft deflection.

Near-centerline Mounting of casing feet ensures optimal alignment and performance when operating at elevated temperatures.

Long-radius Crossovers minimize flow losses between stages, helping to enable high efficiencies.

Cap Nuts are arranged on the top half casing parting flange, allowing easy casing removal for rotor inspection and maintenance.

Replaceable Casing and Impeller Wear Rings control interstage leakage and provide hydraulic stability.
