FBCN Centrifugal Pumps in Siriri

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. FB Bombas is a Brazilian industrial-pump manufacturer since 1944, with a factory in Cabreúva/SP and a technical team for projects in Siriri. The FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series cover the same applications served by imported equipment — with advantages in lead time (no import), direct factory technical support, spare parts for FB pumps themselves and Portuguese-speaking application engineering. In a normalized centrifugal retrofit, ASME B73.1 requires that units of the same standard dimension designation, from any source of supply, be interchangeable as to mounting dimensions, suction and discharge nozzles, input shaft and foundation bolt holes.

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 Siriri 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.

Yes. On pumps installed in Siriri, FB Bombas application engineering applies ISO 10816 (velocity RMS in mm/s) to diagnose misalignment, imbalance, bearing defects and cavitation. The scope covers baseline captured at startup, spectral comparison throughout PM campaigns and recommendation of interventions — re-balancing, bearing replacement, laser alignment — before the machine reaches the standard's 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 Siriri.

FBE external gear pumps can operate with fluids up to 100,000 SSU (approximately 22,000 cSt). For very high viscosities, rotation is reduced to maintain volumetric efficiency and component life. Engineering sizes each application in Siriri according to the actual viscosity profile.

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.

Yes. The design of the FBE and FBCN lines favors direct access to wear-prone components — disassembly and inspection are done with conventional tools. The routine gets even simpler with detailed technical manuals and replacement parts supplied straight from the factory.

Yes, we do. Supply for Siriri 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.
