FBCN Centrifugal Pumps in Agrestina

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.

Yes. In addition to the standard portfolio, FB Bombas develops custom solutions for special applications, including modifications in construction materials, sealing arrangements, integrated heating systems, skids, mobile assemblies and retrofit of existing installations. Special projects go through engineering before manufacturing.

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 Agrestina 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.

Yes. FB Bombas manufactures pumps for stationary fire protection systems in compliance with NFPA (National Fire Protection Association) and ABNT NBR 16704 standards, serving building and industrial projects that require these certifications.

Application engineering starts from four variables — flow, differential pressure, temperature and viscosity — and refines with available NPSH, duty cycle and chemical compatibility. The study is free for customers in Agrestina and results in the exact model recommendation, not a generic family.

Send the application data through the website form, WhatsApp +55 11 97287-4837 or email comercial@fbbombas.com.br: fluid (name and viscosity at operating temperature), target flow in m³/h, discharge head in m, available NPSH, operating temperature and regime — continuous or intermittent. After reviewing the briefing, application engineering returns a preliminary technical proposal, characteristic curve, suggested materials and delivery lead time for your project in Agrestina.

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.

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 Agrestina 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 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.

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 Agrestina. 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.
