FBE Gear Pumps in São Luís do Quitunde

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 São Luís do Quitunde 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.

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 São Luís do Quitunde and surrounding areas.

During a plant shutdown in São Luís do Quitunde, 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.

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. On the factory bench in Cabreúva/SP the FAT (Factory Acceptance Test) is carried out: hydraulic test with characteristic-curve measurement (Q × H), hydraulic efficiency, NPSHr and ISO 10816 vibration — witnessed by customer inspection when specified. The SAT (Site Acceptance Test) on São Luís do Quitunde projects counts on application engineering during commissioning, including startup checklist, laser alignment and recording of the baseline vibration signature.

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.

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 São Luís do Quitunde.

Yes. The FBCN series complies with ASME B73.1 (North American standard for horizontal end-suction process centrifugal pumps) — which enables retrofit on existing baseplates in São Luís do Quitunde plants, whoever manufactured the installed unit, provided the dimension designation matches. Shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the standard: the complete FBCN pump goes in and piping and baseplate stay put.

It is. A Brazilian manufacturer since 1944, FB Bombas runs its factory in Cabreúva/SP and keeps a technical team focused on projects in São Luís do Quitunde. Across the duty ranges currently held by imported lines, the FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series offer equivalent coverage, with better lead times by dispensing with imports, factory-direct technical support, spare parts for FB pumps and Portuguese-speaking application engineering. On a normalized pump, the existing baseplate is preserved when the ASME B73.1 dimension designation matches — which the standard makes independent of the installed brand.
