FBCN Centrifugal Pumps in Carnaubal

FB Bombas has been manufacturing industrial pumps since 1944, with over 82 years of continuous experience. The factory in Cabreúva/SP operates with engineering, manufacturing and testing under one roof, ensuring total quality control on every unit supplied to Carnaubal and all of Brazil.

The FB Bombas rotating set is balanced per ISO 21940 G2.5 (a balancing grade equivalent to API 610 requirements for heavy-duty service) — required for critical projects in Carnaubal with continuous regime, plants with online vibration monitoring or applications with high cost of unplanned downtime. For machines running above 3,600 RPM or with rotating mass over 50 kg, balancing is performed on two planes with a piezoelectric sensor.

Yes. FB Bombas’ application engineering analyzes the installed pump specifications (flow, pressure, viscosity, temperature) and proposes dimensional or functional technical equivalence with one of our series. Many clients in Carnaubal have already made this replacement with gains in lead time, cost and local support.

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.

Yes. The FBE and FBCN lines were designed with easy access to wear-prone components, allowing disassembly and inspection with conventional tools. Detailed technical manuals and direct factory replacement parts availability simplify maintenance routines.

Lead time depends on the chosen series, construction materials and stock availability. For standard configuration pumps, lead times are shorter; for special or custom constructions, the schedule is informed in the technical proposal. Logistics for Carnaubal is handled by our regular road operator.

Yes. FB Bombas application engineering supports ISO 10816 vibration analysis (velocity RMS in mm/s) for diagnosing misalignment, imbalance, bearing defects and cavitation on pumps installed in Carnaubal. The service includes baseline capture at startup, spectral comparison during PM campaigns, and intervention recommendations (re-balancing, bearing replacement, laser alignment) before vibration exceeds the standard’s zone D.

The FB line covers a wide range: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products (FBE series); raw and treated water, process fluids, industrial effluents (FBCN series); thermal oil at elevated temperatures (FBOT series). Each application is sized according to fluid viscosity, temperature and chemical compatibility.

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 Carnaubal.

For critical parts (mechanical seal, impeller, shaft, wear ring, bearings) during a plant shutdown in Carnaubal, 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.
