FBCN Centrifugal Pumps in Ortigueira

In the pulp and paper industry, the FBCN series is the primary choice for pulp, black liquor, process water and effluent pumping. FBE serves applications with starch, glue and viscous additives. FBOT circulates thermal oil in dryers and calenders.

It does. FB Bombas' retrofit service for existing installations encompasses updated seals, replaced worn components, adjustment to new fluids and improved hydraulic performance. To evaluate each case, the reference is the technical report on the current installation.

The FB Bombas rotating set is balanced per ISO 21940 G2.5 (a balancing grade equivalent to API 610 requirements for heavy-duty service) — required for critical projects in Ortigueira with continuous regime, plants with online vibration monitoring or applications with high cost of unplanned downtime. For machines running above 3,600 RPM or with rotating mass over 50 kg, balancing is performed on two planes with a piezoelectric sensor.

It directly affects viscous fluids: viscosity at winter cold start can be several times higher than at operation, raising the torque demanded from the motor. For oils, asphalt and resins, engineering evaluates a heating jacket and sizes the drive for the most severe condition — not the average.

Yes. On pumps installed in Ortigueira, 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.

It does. When a special application demands something beyond the standard portfolio, FB Bombas develops the solution: modified construction materials, specific sealing arrangements, system-integrated heating, skids, mobile assemblies and retrofit of existing installations. Engineering reviews each special project as a step prior to manufacturing.

Maximum temperature depends on the series: FBE and FBEI operate up to 350°C with heating jacket and special sealing; FBOT operates up to 350°C in thermal oil circuits; FBCN operates up to 260°C with proper materials and sealing. Correct sizing of sealing and materials is essential for safe operation.

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

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 Ortigueira, the SAT (Site Acceptance Test) is supported by application engineering during commissioning, with startup checklist, laser alignment and baseline vibration-signature capture.

Four pillars: a current Petrobras CRCC registration for Oil & Gas; API 676 (positive displacement) on the FBE series; ASME B73.1 (process centrifugals) on the FBCN series; and NFPA 20 / NBR 16704 compliance for stationary fire pumps.
