Construction features
- Spiral body cast in single piece, supported on its own feet, with wear ring on suction side
- Radial single-suction impeller with wear ring on pressure side (except models 25-150, 32-125 and 32-125.1)
- Shaft with protection sleeve in the sealing region
- Back-pull-out construction — bearing is removed without dismantling piping
- Flanges (Table 1, p.5): cast iron ANSI B16.1 125 Lb FF or 250 Lb FF, depending on size; steels and ductile iron ANSI B16.5/B16.42 150 Lb RF
Sealing options
- Packing: Table 3 on page 7 relates temperature and pressure for ANSI B16.1 125 and 250 lb flanges
- Mechanical seal: Table 3 lists 90 °C and 10 bar; confirm the arrangement appropriate to the process conditions
- Seal chamber and materials depend on the application; fluids with suspended solids require consultation with FB (section 2.3)
Available materials
- Cast Iron (peripheral speed up to 40 m/s)
- Ductile Iron (up to 60 m/s)
- Carbon Steel (up to 60 m/s)
- Stainless Steel (up to 80 m/s)
Who is this manual for
Process, maintenance and design engineers who need to consult FBCN construction, sealing arrangements, operating limits and dimensions.
When to use
Read for sizing (flow × head tables, pressure × temperature limits), preventive maintenance planning and selection of sealing chamber appropriate to the fluid.
Keep the equipment identification at hand.
Keep the equipment identification with the document when continuing the conversation with our team.
Check the identification
If you already have a pump, provide the series and code on its nameplate. A photo helps our team identify the equipment.
Consult the series document
Use the manual code as a reference. Dimensions and construction options must be checked for your equipment model and configuration.
Keep the context
For a question, replacement or new selection, share the model and the page you are consulting. Include the fluid and operating conditions you know.
