FBCN Centrifugal Pumps in Caraíbas

Yes. FB Bombas is a Brazilian industrial-pump manufacturer since 1944, with a factory in Cabreúva/SP and a technical team for projects in Caraíbas. 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.

Yes, provided the dimension designation coincides. By following ASME B73.1 — the North American dimensional standard for end-suction process pumps — the FBCN occupies the standardised installation envelope defined by the norm, which does not depend on who built the pump running in Caraíbas plants. What is supplied is the complete pump: baseplate, suction/discharge piping and foundations usually remain. FB application engineering runs the dimensional gap analysis before supply, covering flow, head and required NPSH as well.

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.

It does. The technical support and logistics covering Caraíbas are the same applied to the metropolitan region and nearby microregions. That operating radius enables coordinated service to industrial plants distributed across several cities.

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.

Yes — the standard catalog is only the starting point. For special applications, FB Bombas engineers custom solutions: changes in construction materials, sealing arrangements, integrated heating systems, skids, mobile assemblies and retrofit of existing installations. Before manufacturing, every special project is validated by engineering.

ISO 21940 G2.5 is the grade applied to the rotating set of FB Bombas pumps — direct equivalence with what API 610 asks for heavy-duty service. Critical projects in Caraíbas depend on this standard: continuous-regime operation, online vibration monitoring at the plant or high cost tied to unplanned downtime. When rotation exceeds 3,600 RPM or rotating mass goes over 50 kg, two-plane balancing is executed using a piezoelectric sensor.

Four families are manufactured in Cabreúva/SP: external gear FBE and internal gear FBEI for viscous fluids, standardized centrifugal FBCN for low-viscosity liquids and FBOT for thermal oil circuits up to 350 °C. Fire-fighting systems per NFPA 20 / NBR 16704 complete the line.

Yes. ASME B73.1 dimensional compliance — the North American standard for horizontal end-suction process centrifugal pumps — is a feature of the FBCN series and enables retrofit on existing baseplates in Caraíbas plants, regardless of which brand occupied the base, provided the designation coincides. Shaft, suction/discharge flanges, casing feet and impeller centerline obey the standard, so the new pump takes the position without touching piping or baseplate.

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.
