FBCN Centrifugal Pumps in Água Doce do Norte

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 Água Doce do Norte have already made this replacement with gains in lead time, cost and local support.

Yes. A complete technical Data Book accompanies each FB Bombas pump that reaches Água Doce do Norte: 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.

During a plant shutdown in Água Doce do Norte, critical parts — mechanical seal, impeller, shaft, wear ring, bearings — enter FB Bombas' emergency flow: pre-invoicing, priority dispatch and choice of alternative modal (express road or air, depending on distance and criticality). Typical lead time depends on the region and the window is negotiated case by case. Customers with an installed base and scheduled PM can keep part of the stock on consignment at the plant.

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.

It offers both. The FAT (Factory Acceptance Test) takes place on the Cabreúva/SP bench and covers hydraulic testing, characteristic-curve measurement (Q × H), hydraulic efficiency, NPSHr and ISO 10816 vibration; when the customer specifies, inspection witnesses the tests. In the SAT (Site Acceptance Test) of Água Doce do Norte projects, application engineering supports commissioning with startup checklist, laser alignment and capture of the baseline vibration signature.

Since 1944 — over 82 years of continuous experience manufacturing industrial pumps. In Cabreúva/SP, the factory brings engineering, manufacturing and testing together under one roof, which assures total quality control on each unit shipped to Água Doce do Norte and all across Brazil.

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 Água Doce do Norte. 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.

It depends on the service: fluid, temperature and operating pressure determine the configuration, which engineering defines. Available options are single seal, double seal (tandem or back-to-back), cartridge version and, in specific applications, packing glands. Hazardous fluids call for a double seal with barrier — that is the recommended option.

Yes, we do. Supply for Água Doce do Norte ships directly from the factory in Cabreúva/SP and includes engineering support, spare parts for all four series and free sizing — critical projects may receive an on-site technical visit.

Four families are manufactured in Cabreúva/SP: external gear FBE and internal gear FBEI for viscous fluids, standardized centrifugal FBCN for low-viscosity liquids and FBOT for thermal oil circuits up to 350 °C. Fire-fighting systems per NFPA 20 / NBR 16704 complete the line.
