For the industrial park of Tuntum, the FBE series answers the services kinetic hydraulics cannot cover: transfer with stable flow under fluctuating pressure, dosing proportional to speed and high-viscosity fluids — the typical case of óleos e água industrial. Sizing validates starting torque at the coldest condition of the year — the classic mistake that shears keys in undersized pumps. In Tuntum, materials such as austenitic stainless steels (AISI 304/316) with attention to thermal expansion answer the requirements of óleos industriais and água industrial — a combination that drives service life of casing, impeller, shaft and shaft sleeve, refined via corrosion analysis using removal rates (mpy). For the technical profile observed in Tuntum, FB Bombas application engineering recommends FBEI and FBCN as a starting point for sizing, subject to refinement per Q×H curve, available NPSH and actual fluid temperature. 100% of pumps bound for Tuntum pass through the Cabreúva-SP hydraulic bench — acceptance testing with multi-point curve readings and G2.5 dynamic balancing.
Fluid-roster complexity in Tuntum is low — lean fluid roster — technical operation focused on few main vectors. A GDP of R$ 410 million (IBGE, 2023) with a services profile (27.6% of value added in 2021) places Tuntum's local demand in the utilities field: building pressurization, light process water and fire-fighting systems. The demand profile in Tuntum reflects high industrial density — multiple plants in a small radius, meaningful cumulative demand. In Tuntum, óleos industriais and água industrial form the typical fluid set — guiding both series selection (gear, centrifugal, thermal oil) and constructive detail (closed/open/semi-open impeller). Tuntum shows cases like series FBEI for transferência geral and series FBCN for utilidades — a package FB Bombas addresses with real-curve sizing, material recommendation and dimensioned seal configuration. Tuntum, among the 50 most populous cities in MA, maintains a relevant industrial base, sustains a predictable B2B demand chain — an ideal profile for scheduled supply and multi-year replacement contracts.
For Tuntum, 72h to 7 days, depending on modal and dry season is the standard contractual transit window — compressible via emergency air modal for critical parts, on specific demand. Cabreúva-SP → Tuntum via BR-135 (via Belém-Brasília BR-153) (2025 km): a corridor with regular FB freight history, supporting indivisible loads and sets with escort when the gauge demands. For Tuntum, FB dispatch is preceded by: hydrostatic test at 1.5× design pressure, performance run with curve points, G2.5 dynamic balancing and Data Book closure — all traceable by serial number.

Three fluid fronts are covered by the FB series. FBE: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products. FBCN: raw and treated water, process fluids and industrial effluents. FBOT: thermal oil at elevated temperatures. Fluid viscosity, temperature and chemical compatibility guide the sizing of every application.

FB Bombas has been manufacturing in Brazil since 1944.
Every FB pump leaves the factory with a warranty against manufacturing defects, under the terms detailed in the commercial proposal. The condition is that installation, operation and maintenance respect the manual's parameters and the sizing defined by engineering. For details on your project in Tuntum, talk to our technical team.
Yes. Correct sizing is the main lever for energy efficiency — an oversized or undersized pump wastes energy. FB Bombas engineering calculates the optimal operating point considering the actual process conditions in Tuntum, optimizing the flow/pressure/power ratio.
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.
They can. FB Bombas' accreditation in FINAME (the BNDES Special Industrial Financing Agency), as a Brazilian manufacturer, makes equipment destined for Tuntum eligible for the BNDES Finame lines — Industrial Working Capital, Modernization and Capital Goods —, which offer preferential conditions for national industry. The product's FINAME code is provided by the commercial team on the technical proposal, ready to compose the customer's financial plan.
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. 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 Tuntum. 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.
