FBCN Centrifugal Pumps in Caxias

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.

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

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 Caxias.

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 Caxias 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.

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.

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 Caxias is handled by our regular road operator.

Yes. The FBCN series follows ASME B73.1 normalization (North American dimensional standard for end-suction process pumps) — which makes the pump-and-motor set interchangeable with global manufacturers (KSB, Sulzer, Goulds, Flowserve) already installed in plants in Caxias. For retrofits, the existing baseplate, suction/discharge piping and foundations are usually preserved; what changes is the rotating set. FB application engineering performs the dimensional gap analysis prior to supply.

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.

Yes. Every FB Bombas pump delivered to Caxias 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.

Yes. FB Bombas’ application engineering analyzes the installed pump specifications (flow, pressure, viscosity, temperature) and proposes dimensional or functional technical equivalence with one of our series. Many clients in Caxias have already made this replacement with gains in lead time, cost and local support.
