FBCN Centrifugal Pumps in Carmo do Cajuru

FB Bombas manufactures four major lines: FBE (external gear) for viscous fluids, FBEI (internal gear) for lubricating fluids, FBCN (normalized centrifugal) for water and low-viscosity fluids, and FBOT (specific centrifugal) for thermal oil circuits. We also serve fire protection systems in compliance with NFPA and NBR 16704.

Manufacturing in Brazil since 1944, FB Bombas delivers shorter lead times — with no import dependency —, direct technical support from FB engineering, in-house manufactured replacement parts, local-currency pricing free of exchange rate exposure, and on-site service for projects in Carmo do Cajuru and surrounding areas.

Service to Carmo do Cajuru is handled directly by the FB Bombas team at the Cabreúva/SP factory. That means direct contact with application engineering for sizing, a complete technical quotation within 3-5 business days and original spare parts supplied at factory-direct pricing. On-site technical visits to Carmo do Cajuru are planned based on project criticality.

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 Carmo do Cajuru. 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.

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 Carmo do Cajuru.

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.

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. 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.

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 Carmo do Cajuru 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.
