Technical summary
The FBEI gear-pump line is specified in Duque Bacelar, Maranhão for local industry — flow and pressure set by the actual system curve. Cabreúva-SP factory (2177 km), API 676 and direct technical service from FB engineering.


Typical fluids in Duque Bacelar's industrial operations include óleos industriais and água industrial — a vector that determines whether the correct specification is the FBE/FBEI (gear) or FBCN/FBOT (centrifugal / thermal oil) series. Only 481 km from the industrial district cluster of Maracanau, Duque Bacelar benefits from logistics spillover and movement of technical professionals — FB Bombas has a service track record in the region. FB Bombas is a Brazilian manufacturer of industrial pumps serving Duque Bacelar, Maranhão, with the FBE, FBCN, FBOT and FBEI series applied to the local industry sector that dominates the region. Direct factory service from Cabreúva-SP, with application engineering for technical sizing and certification under CRCC Petrobras / API 610 / ASME B73.1 per project specification. For projects in Duque Bacelar that demand formal technical qualification, FB Bombas series cover API 610 (FBCN), API 676 (FBE/FBEI), NFPA 20 and NBR 16704 (FBFS systems) — a combination that removes the need for additional suppliers across fire-fighting and process scope. Road access runs via BR-135 (via Belém-Brasília BR-153), with branches through BR-135, BR-222 and BR-316 — a corridor that sets delivery times for rotating equipment and the logistics of technical service. FB Bombas application engineering serves Duque Bacelar with custom technical sizing: system characteristic curve, available NPSH, in-service viscosity and mechanical-seal strategy (API Plan 11, 13, 52 or 53 by criticality). FB Bombas serves Duque Bacelar from its Cabreúva-SP factory, with transport via BR-135 (via Belém-Brasília BR-153) and application-engineering support for dimensioning according to the actual operation profile.

Material selection for óleos industriais and água industrial in Duque Bacelar considers austenitic stainless steels (AISI 304/316) with attention to thermal expansion — a specification FB Bombas details on a matweb sheet after fluid chemical analysis. The transferência geral and utilidades set accounts for a large share of industrial demand in Duque Bacelar; FB Bombas keeps documented history of analogous applications for sizing benchmarks. Duque Bacelar typically calls for FBEI and FBCN — an initial recommendation based on local productFit, dominant industrial cluster and identified fluid profile; final technical approval is refined by application engineering. For Duque Bacelar, the FB protocol includes hydrostatic test at 1.5× design pressure, performance run and ISO 21940 G2.5 balancing — all documented in the Data Book.
Fluid-roster complexity in Duque Bacelar is low — lean fluid roster — technical operation focused on few main vectors. Typical seasonality of the distrito-industrial cluster (variable seasonality depending on plant mix — individualized planning) directly impacts supply scheduling and PMs in Duque Bacelar. The demand profile in Duque Bacelar reflects low industrial density — typically standalone projects, without regional cumulative volume. The fluid catalogue in Duque Bacelar (óleos industriais and água industrial) demands case-by-case technical analysis: pour point, Saybolt viscosity at operating temperature, suspended solids and pH profile. Duque Bacelar 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. The distrito-industrial cluster around Duque Bacelar concentrates applications diverse applications — specialty chemicals, hydraulic oils, purified water and thermal oils — a technical package where FB Bombas has commissioning, retrofit and long-term support history.
For Duque Bacelar, 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 → Duque Bacelar via BR-135 (via Belém-Brasília BR-153) (2177 km): a corridor with regular FB freight history, supporting indivisible loads and sets with escort when the gauge demands. For Duque Bacelar, 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.

Brazilian sectors for which FB Bombas sizes equipment — complete technical guides per application.
Regional service from Duque Bacelar — same series, same factory in Cabreúva/SP.
Yes. FB Bombas serves Duque Bacelar and the entire surrounding region with supply, technical support and replacement parts directly from the factory in Cabreúva/SP. Support includes sizing at no cost and, for critical projects, on-site technical visits.
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 Duque Bacelar.
FB Bombas holds: active CRCC at Petrobras (supplier registry for Oil & Gas); compliance with API 676 (international standard for positive displacement pumps — FBE series); compliance with API 610 (standard for centrifugal pumps in refineries — FBCN series); compliance with NFPA (National Fire Protection Association) standards and ABNT NBR 16704 for stationary fire protection pump systems.
Yes. FB Bombas is a Brazilian manufacturer accredited in FINAME (BNDES Special Industrial Financing Agency), which qualifies equipment supplied to Duque Bacelar for BNDES Finame financing lines (Industrial Working Capital, Modernization, Capital Goods) with preferential conditions for national industry. The commercial team provides the product FINAME code on the technical proposal for inclusion in the customer financial plan.
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.
Yes. Every FB Bombas pump delivered to Duque Bacelar comes with a complete technical Data Book: hydraulic test certificate, material certificates (stainless, duplex, ductile cast iron per spec), ISO 21940 G2.5 balancing report, characteristic curve measured on the bench, API 682 mechanical-seal data sheets, operation and maintenance manual, and as-built drawings. All documentation is traceable by the unit serial number.
Yes. FB Bombas serves the entire metropolitan region and microregions neighboring Duque Bacelar with the same technical support and logistics structure. This regional reach allows serving industrial plants distributed across multiple cities in a coordinated way.
Yes. The FBCN series follows ASME B73.1 normalization (North American dimensional standard for end-suction process pumps) — which makes the pump-and-motor set interchangeable with global manufacturers (KSB, Sulzer, Goulds, Flowserve) already installed in plants in Duque Bacelar. For retrofits, the existing baseplate, suction/discharge piping and foundations are usually preserved; what changes is the rotating set. FB application engineering performs the dimensional gap analysis prior to supply.
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 Duque Bacelar, optimizing the flow/pressure/power ratio.
Yes. Since FB Bombas manufactures entirely in Cabreúva/SP, replacement parts for the FBE, FBEI, FBCN and FBOT series are available directly from the factory, with short lead times for scheduled stops and priority service for emergencies. This significantly reduces total cost of ownership.
