FBCN Centrifugal Pumps in Chã Grande

Four pillars: a current Petrobras CRCC registration for Oil & Gas; API 676 (positive displacement) on the FBE series; ASME B73.1 (process centrifugals) on the FBCN series; and NFPA 20 / NBR 16704 compliance for stationary fire pumps.

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 Chã Grande.

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.

Every FB pump leaves the factory with a warranty against manufacturing defects, under the terms detailed in the commercial proposal. The condition is that installation, operation and maintenance respect the manual's parameters and the sizing defined by engineering.

They do. The FBCN series dimensionally meets ASME B73.1, the North American standard for horizontal end-suction process centrifugal pumps. In practice, a Chã Grande plant running a normalized pump of the same designation achieves retrofit on the already-installed baseplate: since shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the same standard, the FBCN pump takes the place of the previous one — piping and baseplate stay intact. Hydraulic equivalence (Q×H and NPSH) is checked separately, on the data sheet.

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.

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 Chã Grande 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 design of the FBE and FBCN lines favors direct access to wear-prone components — disassembly and inspection are done with conventional tools. The routine gets even simpler with detailed technical manuals and replacement parts supplied straight from the factory.

Yes. A complete technical Data Book accompanies each FB Bombas pump that reaches Chã Grande: hydraulic test certificate, material certificates (stainless steel, duplex and ductile cast iron per spec), ISO 21940 G2.5 balancing report, characteristic curve measured on the test bench, API 682 mechanical-seal data sheets, operation and maintenance manual and as-built drawings. The unit serial number traces all this documentation.

It does. The standard used is ISO 10816, with velocity RMS in mm/s, and the diagnosis — conducted by FB Bombas application engineering — identifies misalignment, imbalance, bearing defects and cavitation on pumps operating in Chã Grande. At startup the baseline is captured; in PM campaigns, spectral comparison is performed; and interventions (re-balancing, bearing replacement, laser alignment) are recommended before vibration enters zone D.
