BF and BFD Between Bearings, Axially Split Multistage Pumps
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.
- 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.
