FBCN Centrifugal Pumps in São Gabriel

Four families are manufactured in Cabreúva/SP: external gear FBE and internal gear FBEI for viscous fluids, standardized centrifugal FBCN for low-viscosity liquids and FBOT for thermal oil circuits up to 350 °C. Fire-fighting systems per NFPA 20 / NBR 16704 complete the line.

FB Bombas has been manufacturing industrial pumps since 1944, with over 82 years of continuous experience. The factory in Cabreúva/SP operates with engineering, manufacturing and testing under one roof, ensuring total quality control on every unit supplied to São Gabriel and all of Brazil.

There is no single configuration — engineering selects the mechanical seal based on the fluid, temperature and operating pressure. The range includes single seals, double seals in tandem or back-to-back arrangement, cartridge seals and packing glands in specific applications. When the fluid is hazardous, the recommendation is a double seal with barrier.

Yes. On the factory bench in Cabreúva/SP the FAT (Factory Acceptance Test) is carried out: hydraulic test with characteristic-curve measurement (Q × H), hydraulic efficiency, NPSHr and ISO 10816 vibration — witnessed by customer inspection when specified. The SAT (Site Acceptance Test) on São Gabriel projects counts on application engineering during commissioning, including startup checklist, laser alignment and recording of the baseline vibration signature.

Send the application data through the website form, WhatsApp +55 11 97287-4837 or email comercial@fbbombas.com.br: fluid (name and viscosity at operating temperature), target flow in m³/h, discharge head in m, available NPSH, operating temperature and regime — continuous or intermittent. After reviewing the briefing, application engineering returns a preliminary technical proposal, characteristic curve, suggested materials and delivery lead time for your project in São Gabriel.

They do. The FBCN series dimensionally meets ASME B73.1, the North American standard for horizontal end-suction process centrifugal pumps. In practice, a São Gabriel plant running a normalized pump of the same designation achieves retrofit on the already-installed baseplate: since shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the same standard, the FBCN pump takes the place of the previous one — piping and baseplate stay intact. Hydraulic equivalence (Q×H and NPSH) is checked separately, on the data sheet.

There are three channels: WhatsApp +55 11 97287-4837, email comercial@fbbombas.com.br and the form on our website. Technical questions get priority response within the same business day — the reply comes directly from application engineering.

Yes. FB Bombas offers retrofit of existing installations, including seal upgrades, replacement of worn components, adaptation for new fluids and hydraulic performance improvement. The assessment is based on a technical report of the current installation.

During a plant shutdown in São Gabriel, critical parts — mechanical seal, impeller, shaft, wear ring, bearings — enter FB Bombas' emergency flow: pre-invoicing, priority dispatch and choice of alternative modal (express road or air, depending on distance and criticality). Typical lead time depends on the region and the window is negotiated case by case. Customers with an installed base and scheduled PM can keep part of the stock on consignment at the plant.

Credentials include an active Petrobras CRCC, API 676 compliance on the FBE gear line, ASME B73.1 compliance on the FBCN centrifugal and adherence to NFPA 20 and NBR 16704 on fire-fighting systems. Technical documentation and data book accompany supplies upon requirement.
