FBCN Centrifugal Pumps in Cantagalo

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 Cantagalo 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.

Yes. The entire metropolitan region and the microregions around Cantagalo receive from FB Bombas the same technical support and logistics structure. With this regional reach, industrial plants spread across several cities are served in a coordinated manner.

It directly affects viscous fluids: viscosity at winter cold start can be several times higher than at operation, raising the torque demanded from the motor. For oils, asphalt and resins, engineering evaluates a heating jacket and sizes the drive for the most severe condition — not the average.

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 Cantagalo is handled by our regular road operator.

Three fluid fronts are covered by the FB series. FBE: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products. FBCN: raw and treated water, process fluids and industrial effluents. FBOT: thermal oil at elevated temperatures. Fluid viscosity, temperature and chemical compatibility guide the sizing of every application.

They are. For each delivery to Cantagalo, FB Bombas assembles the unit's complete technical Data Book, containing: hydraulic test certificate, material certificates — stainless steel, duplex or ductile cast iron, per spec —, ISO 21940 G2.5 balancing report, characteristic curve obtained on the bench, API 682 mechanical-seal data sheets, operation and maintenance manual and as-built drawings. Full traceability happens through the serial number.

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.

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