FBCN Centrifugal Pumps in Vargem Grande

There is no single configuration — engineering selects the mechanical seal based on the fluid, temperature and operating pressure. The range includes single seals, double seals in tandem or back-to-back arrangement, cartridge seals and packing glands in specific applications. When the fluid is hazardous, the recommendation is a double seal with barrier.

Yes. Existing installations can undergo retrofit with FB Bombas — the scope covers seal upgrades, swapping worn components, adaptation for new fluids and hydraulic performance gains. A technical report on the current installation serves as the basis for the assessment.

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 Vargem Grande projects, application engineering supports commissioning with startup checklist, laser alignment and capture of the baseline vibration signature.

FB Bombas' trajectory as an industrial pump manufacturer began in 1944 and adds up to over 82 years of continuous experience. Engineering, manufacturing and testing operate under one roof at the Cabreúva/SP factory — a guarantee of total quality control on every unit that reaches Vargem Grande and the rest of Brazil.

The FB portfolio handles an extensive spectrum of fluids. The FBE series takes mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins plus viscous chemical and hydraulic products; the FBCN series works with raw and treated water, process fluids and industrial effluents; the FBOT series is dedicated to thermal oil at elevated temperatures. Each case is sized considering viscosity, temperature and chemical compatibility.

Maximum temperature depends on the series: FBE and FBEI operate up to 350°C with heating jacket and special sealing; FBOT operates up to 350°C in thermal oil circuits; FBCN operates up to 260°C with proper materials and sealing. Correct sizing of sealing and materials is essential for safe operation.

Yes. On pumps installed in Vargem Grande, 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.

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.

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 Vargem Grande 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.

Yes. The process starts with FB Bombas' application engineering, which studies the installed pump's specifications — flow, pressure, viscosity, temperature — and indicates the dimensional or functional technical equivalence within our series. In Vargem Grande, many clients have already completed this swap and gained in lead time, cost and local support.
