FBCN Centrifugal Pumps in Cubatão

Yes. Active CRCC at Petrobras and compliance with API 676 (FBE series) and API 610 (FBCN series) qualify FB Bombas to supply refineries and petrochemical plants, including applications in classified areas and hazardous fluids. Factory engineering sizes sealing arrangements and materials according to each specification.

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 Cubatão 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. 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 Cubatão. 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.

Yes. The FBCN series complies with ASME B73.1 (North American standard for horizontal end-suction process centrifugal pumps) — a feature that enables dimensional retrofit on existing baseplates in Cubatão plants originally equipped with KSB, Sulzer, Goulds or Flowserve. Shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the standard; the rotating set is swapped without changing piping or baseplate.

Yes. FB Bombas offers technical training for operations and maintenance teams in Cubatão, 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.

FBE external gear pumps can operate with fluids up to 100,000 SSU (approximately 22,000 cSt). For very high viscosities, rotation is reduced to maintain volumetric efficiency and component life. Engineering sizes each application in Cubatão according to the actual viscosity profile.

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.

Shorter delivery times (no import dependency), direct technical support from FB engineering, replacement parts with in-house manufacturing, prices in local currency (no exchange rate exposure) and on-site service for projects in Cubatão and surrounding areas. FB Bombas has been manufacturing in Brazil since 1944.

Yes. FB Bombas is a Brazilian industrial-pump manufacturer since 1944, with a factory in Cabreúva/SP and a technical team for projects in Cubatão. The FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series cover applications typically served by global manufacturers such as KSB, Sulzer, Imbil and Grundfos — with advantages in lead time (no import), direct support without intermediaries, fast spare-parts availability and Portuguese-speaking application engineering. For retrofits, ASME B73.1 normalization ensures dimensional interchangeability with existing baseplates.
