FBCN Centrifugal Pumps in Criciúma

For critical parts (mechanical seal, impeller, shaft, wear ring, bearings) during a plant shutdown in Criciúma, FB Bombas runs an emergency flow: pre-invoicing, priority dispatch and alternative modal (express road or air transport depending on distance and criticality). Typical lead time varies by region, with a window negotiable case by case. For customers with an installed base and scheduled PM, part of the stock can be kept on consignment at the plant.

Credentials include an active Petrobras CRCC, API 676 compliance on the FBE gear line, ASME B73.1 compliance on the FBCN centrifugal and adherence to NFPA 20 and NBR 16704 on fire-fighting systems. Technical documentation and data book accompany supplies upon requirement.

FB Bombas' rotating set balancing follows ISO 21940 G2.5 — a grade equivalent to the API 610 requirement for heavy-duty service. It is the level demanded in critical Criciúma projects: continuous regime, plants with online vibration monitoring or operations where unplanned downtime is expensive. Above 3,600 RPM or with rotating mass beyond 50 kg, balancing is done on two planes, with a piezoelectric sensor.

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

They are. For each delivery to Criciúma, 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.

It does. FB Bombas' retrofit service for existing installations encompasses updated seals, replaced worn components, adjustment to new fluids and improved hydraulic performance. To evaluate each case, the reference is the technical report on the current installation.

They do. In the FBE and FBCN lines, wear-affected components sit in easily accessible positions, so conventional tools suffice for disassembly and inspection. Add detailed technical manuals and factory-direct availability of replacement parts — and maintenance becomes an uncomplicated routine.

Yes. On the factory bench in Cabreúva/SP the FAT (Factory Acceptance Test) is carried out: hydraulic test with characteristic-curve measurement (Q × H), hydraulic efficiency, NPSHr and ISO 10816 vibration — witnessed by customer inspection when specified. The SAT (Site Acceptance Test) on Criciúma projects counts on application engineering during commissioning, including startup checklist, laser alignment and recording of the baseline vibration signature.

Limits vary by series. FBE and FBEI: up to 350°C, provided a heating jacket and special sealing are used. FBOT: up to 350°C in thermal oil circuits. FBCN: up to 260°C, with materials and sealing suited to the service. Well-sized sealing and materials are a condition for safe operation in these ranges.

It does. When a special application demands something beyond the standard portfolio, FB Bombas develops the solution: modified construction materials, specific sealing arrangements, system-integrated heating, skids, mobile assemblies and retrofit of existing installations. Engineering reviews each special project as a step prior to manufacturing.
