FBCN Centrifugal Pumps in São João da Barra

FB Bombas manufactures four major lines: FBE (external gear) for viscous fluids, FBEI (internal gear) for lubricating fluids, FBCN (normalized centrifugal) for water and low-viscosity fluids, and FBOT (specific centrifugal) for thermal oil circuits. We also serve fire protection systems in compliance with NFPA and NBR 16704.

Application engineering starts from four variables — flow, differential pressure, temperature and viscosity — and refines with available NPSH, duty cycle and chemical compatibility. The study is free for customers in São João da Barra and results in the exact model recommendation, not a generic family.

FB Bombas holds: active CRCC at Petrobras (supplier registry for Oil & Gas); compliance with API 676 (international standard for positive displacement pumps — FBE series); compliance with ASME B73.1 (standard for process centrifugal pumps — FBCN series); compliance with NFPA (National Fire Protection Association) standards and ABNT NBR 16704 for stationary fire protection pump systems.

Yes. Operations and maintenance teams in São João da Barra count on FB Bombas technical training, structured in modules: sizing and characteristic-curve reading, identifying cavitation through NPSH, mechanical-seal troubleshooting, laser alignment, ISO 10816 vibration analysis and PM (preventive maintenance) practice with bearing and wear-ring replacement. Classes can happen at the customer plant or at the factory in Cabreúva/SP, in-person or hybrid format.

Yes. FB Bombas application engineering supports ISO 10816 vibration analysis (velocity RMS in mm/s) for diagnosing misalignment, imbalance, bearing defects and cavitation on pumps installed in São João da Barra. The service includes baseline capture at startup, spectral comparison during PM campaigns, and intervention recommendations (re-balancing, bearing replacement, laser alignment) before vibration exceeds the standard’s zone D.

It depends on the service: fluid, temperature and operating pressure determine the configuration, which engineering defines. Available options are single seal, double seal (tandem or back-to-back), cartridge version and, in specific applications, packing glands. Hazardous fluids call for a double seal with barrier — that is the recommended option.

For critical parts (mechanical seal, impeller, shaft, wear ring, bearings) during a plant shutdown in São João da Barra, FB Bombas runs an emergency flow: pre-invoicing, priority dispatch and alternative modal (express road or air transport depending on distance and criticality). Typical lead time varies by region, with a window negotiable case by case. For customers with an installed base and scheduled PM, part of the stock can be kept on consignment at the plant.

Each series has its thermal limit: with heating jacket and special sealing, FBE and FBEI reach 350°C; FBOT hits the same 350°C in thermal oil circuits; FBCN goes up to 260°C when fitted with proper materials and sealing. Safe operation requires correctly sized sealing and materials.

After reviewing the briefing, application engineering returns a preliminary technical proposal, characteristic curve, suggested materials and delivery lead time for your project in São João da Barra.

Yes. FB Bombas is a Brazilian industrial-pump manufacturer since 1944, with a factory in Cabreúva/SP and a technical team for projects in São João da Barra. The FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series cover the same applications served by imported equipment — with advantages in lead time (no import), direct factory technical support, spare parts for FB pumps themselves and Portuguese-speaking application engineering. In a normalized centrifugal retrofit, ASME B73.1 requires that units of the same standard dimension designation, from any source of supply, be interchangeable as to mounting dimensions, suction and discharge nozzles, input shaft and foundation bolt holes.
