FBCN Centrifugal Pumps in Limoeiro do Norte

Mechanical seal configuration is defined by engineering according to the fluid, temperature and operating pressure. Options include single seals, double seals (tandem or back-to-back), cartridge seals and packing glands for specific applications. For hazardous fluids, double seals with barrier are recommended.

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 API 610 (standard for centrifugal pumps in refineries — FBCN series); compliance with NFPA (National Fire Protection Association) standards and ABNT NBR 16704 for stationary fire protection pump systems.

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

Yes. FB Bombas offers technical training for operations and maintenance teams in Limoeiro do Norte, with modules on: sizing and reading the characteristic curve, identifying cavitation through NPSH, mechanical-seal troubleshooting, laser alignment, ISO 10816 vibration analysis and PM (preventive maintenance) practice with bearing and wear-ring replacement. Training can be delivered at the customer plant or at the Cabreúva/SP factory, in person or hybrid.

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 Limoeiro do Norte. 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.

FB Bombas manufactures three 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.

Sizing is performed by FB Bombas’ application engineering team based on four key variables: desired flow, differential pressure, working temperature and fluid viscosity. Additional data such as available NPSH, operating cycle and fluid chemical compatibility are also considered. The service is free of charge for customers in Limoeiro do Norte.

Yes. In addition to the standard portfolio, FB Bombas develops custom solutions for special applications, including modifications in construction materials, sealing arrangements, integrated heating systems, skids, mobile assemblies and retrofit of existing installations. Special projects go through engineering before manufacturing.

Quotes can be requested via WhatsApp at +55 11 97287-4837, email comercial@fbbombas.com.br or through our website form. Provide the application (fluid, flow, pressure, temperature) and the technical team will respond with a proposal sized for your conditions in Limoeiro do Norte.

Lead time depends on the chosen series, construction materials and stock availability. For standard configuration pumps, lead times are shorter; for special or custom constructions, the schedule is informed in the technical proposal. Logistics for Limoeiro do Norte is handled by our regular road operator.
