FBCN Centrifugal Pumps in Bequimão

ISO 21940 G2.5 is the grade applied to the rotating set of FB Bombas pumps — direct equivalence with what API 610 asks for heavy-duty service. Critical projects in Bequimão depend on this standard: continuous-regime operation, online vibration monitoring at the plant or high cost tied to unplanned downtime. When rotation exceeds 3,600 RPM or rotating mass goes over 50 kg, two-plane balancing is executed using a piezoelectric sensor.

Yes. The FAT (Factory Acceptance Test) is executed on the factory bench in Cabreúva/SP, with hydraulic test, characteristic-curve measurement (Q × H), hydraulic efficiency, NPSHr and ISO 10816 vibration — witnessed by customer inspection when specified. For projects in Bequimão, the SAT (Site Acceptance Test) is supported by application engineering during commissioning, with startup checklist, laser alignment and baseline vibration-signature capture.

The FB line covers a wide range: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products (FBE series); raw and treated water, process fluids, industrial effluents (FBCN series); thermal oil at elevated temperatures (FBOT series). Each application is sized according to fluid viscosity, temperature and chemical compatibility.

They do. The FBCN series dimensionally meets ASME B73.1, the North American standard for horizontal end-suction process centrifugal pumps. In practice, a Bequimão 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.

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.

Yes. On pumps installed in Bequimão, FB Bombas application engineering applies ISO 10816 (velocity RMS in mm/s) to diagnose misalignment, imbalance, bearing defects and cavitation. The scope covers baseline captured at startup, spectral comparison throughout PM campaigns and recommendation of interventions — re-balancing, bearing replacement, laser alignment — before the machine reaches the standard's zone D.

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. The design of the FBE and FBCN lines favors direct access to wear-prone components — disassembly and inspection are done with conventional tools. The routine gets even simpler with detailed technical manuals and replacement parts supplied straight from the factory.

Yes. Every FB Bombas pump delivered to Bequimão comes with a complete technical Data Book: hydraulic test certificate, material certificates (stainless, duplex, ductile cast iron per spec), ISO 21940 G2.5 balancing report, characteristic curve measured on the bench, API 682 mechanical-seal data sheets, operation and maintenance manual, and as-built drawings. All documentation is traceable by the unit serial number.

Shipment is by road via BR-135 (via Belém-Brasília BR-153), with industrial packaging suited to the journey and tracking until delivery. Sizing, proposal and technical support run in parallel through remote channels — distance does not change the engineering scope, only the logistics planning, reflected in the proposal schedule.
