FBCN Centrifugal Pumps in Sobradinho

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 Sobradinho 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.

It is compatible when the dimension designation is the same. ASME B73.1 (North American dimensional standard for end-suction process pumps), adopted in the FBCN series, defines an envelope common to the whole normalized fleet operating in Sobradinho plants, whoever manufactured the installed unit. In a typical retrofit, baseplate, suction/discharge piping and foundations are preserved, and FB Bombas supplies the complete new pump — not loose parts for third-party equipment. The dimensional and hydraulic gap analysis is executed by application engineering before supplying.

They are. In energy consumption, nothing weighs more than sizing correctly: oversized or undersized pumps generate waste. FB Bombas engineering's job is to define the ideal operating point for the actual process conditions in Sobradinho, optimizing flow, pressure and power together.

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. Existing installations can undergo retrofit with FB Bombas — the scope covers seal upgrades, swapping worn components, adaptation for new fluids and hydraulic performance gains. A technical report on the current installation serves as the basis for the assessment.

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 Sobradinho. 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.

Yes. The process starts with FB Bombas' application engineering, which studies the installed pump's specifications — flow, pressure, viscosity, temperature — and indicates the dimensional or functional technical equivalence within our series. In Sobradinho, many clients have already completed this swap and gained in lead time, cost and local support.

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.

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.
