Technical summary
FBEI gear pumps (FB Bombas) in Loreto, Maranhão: sized for local industry, viscous fluids up to 350°C, API 676 compliance and in-house manufacturing in Cabreúva-SP at 1817 km. Typical critical-parts lead time: 96h to 7 days.


The fluid roster in Loreto (óleos industriais and água industrial) demands attention to viscosity, operating temperature and chemical compatibility — variables that FB application engineering uses to recommend the proper series. The city sits within the IBGE mesoregion Sul Maranhense, a regional grouping of municipalities with similar economic and logistics profiles — useful for comparative analysis and technical-visit routing. FB Bombas aftermarket support in Loreto covers technical service, spare parts with traceable Data Book, scheduled preventive maintenance (PM) and full overhaul on a factory bench with certified FAT. 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. In Loreto, Maranhão, FB Bombas serves local industry projects with the FBE, FBCN, FBOT and FBEI series — dedicated application engineering for sizing against the actual system curve, CRCC Petrobras certification and technical compliance with API 610 (centrifugal), API 676 (gear) and NFPA 20 / NBR 16704 (fire fighting). FB Bombas maintains in Loreto the technical portfolio of CRCC Petrobras + API 610 + API 676 + ASME B73.1 — a regulatory base that spans refining, petrochemicals, mining, sanitation, food, pulp and paper, sugar-ethanol and steel. Service to Loreto is coordinated from the Cabreúva-SP factory, route BR-135 (via Belém-Brasília BR-153) (1817 km), with a technical team for selection, commissioning and replacement support.

Technical fit in Loreto points to FBEI and FBCN as the series suitable for typical local operations — a baseline recommendation; the final specification depends on the specific process parameters. The transferência geral and utilidades set accounts for a large share of industrial demand in Loreto; FB Bombas keeps documented history of analogous applications for sizing benchmarks. Material selection for óleos industriais and água industrial in Loreto 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. For Loreto, 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 Loreto is low — lean fluid roster — technical operation focused on few main vectors. The demand profile in Loreto reflects medium density — regular and predictable opportunity pipeline. Loreto has a specific regional profile, with industrial demand sized to its scale — a feature that enters the sizing of the service strategy. Loreto: óleos industriais and água industrial. Each fluid defines a distinct set of pump requirements — flow, available NPSH, sealing strategy. For Loreto, series FBEI for transferência geral and series FBCN for utilidades — initial reference for technical discussion with application engineering.
Typical transit time to Loreto: 72h to 7 days, depending on modal and dry season — the window used in FB Bombas' standard commercial commitment. The main logistics axis between Cabreúva-SP and Loreto is BR-135 (via Belém-Brasília BR-153), totaling 1817 km — a route that sets the default delivery time for finished equipment. Dispatch from the Cabreúva-SP factory to Loreto occurs after bench hydraulic testing and Data Book verification — mandatory steps in FB's quality control.
FB engineers serve Loreto for the FBE series with a sized proposal — duty point, fluid, field conditions and supply lead time.

Brazilian sectors for which FB Bombas sizes equipment — complete technical guides per application.
Regional service from Loreto — same series, same factory in Cabreúva/SP.
Yes. FB Bombas serves Loreto 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.
Yes. FB Bombas is a Brazilian manufacturer accredited in FINAME (BNDES Special Industrial Financing Agency), which qualifies equipment supplied to Loreto 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. FB Bombas serves the entire metropolitan region and microregions neighboring Loreto with the same technical support and logistics structure. This regional reach allows serving industrial plants distributed across multiple cities in a coordinated way.
FB Bombas has been manufacturing industrial pumps since 1944, with over 82 years of continuous experience. The factory in Cabreúva/SP operates with engineering, manufacturing and testing under one roof, ensuring total quality control on every unit supplied to Loreto and all of Brazil.
The FB line covers a wide range: mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins, viscous chemical and hydraulic products (FBE series); raw and treated water, process fluids, industrial effluents (FBCN series); thermal oil at elevated temperatures (FBOT series). Each application is sized according to fluid viscosity, temperature and chemical compatibility.
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 Loreto. 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.
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.
The FB Bombas rotating set is balanced per ISO 21940 G2.5 (a balancing grade equivalent to API 610 requirements for heavy-duty service) — required for critical projects in Loreto with continuous regime, plants with online vibration monitoring or applications with high cost of unplanned downtime. For machines running above 3,600 RPM or with rotating mass over 50 kg, balancing is performed on two planes with a piezoelectric sensor.
Yes. The FBCN series complies with ASME B73.1 (North American standard for horizontal end-suction process centrifugal pumps) — a feature that enables dimensional retrofit on existing baseplates in Loreto plants originally equipped with KSB, Sulzer, Goulds or Flowserve. Shaft dimensions, suction/discharge flanges, casing feet and impeller centerline follow the standard; the rotating set is swapped without changing piping or baseplate.
Shorter delivery times (no import dependency), direct technical support from FB engineering, replacement parts with in-house manufacturing, prices in local currency (no exchange rate exposure) and on-site service for projects in Loreto and surrounding areas. FB Bombas has been manufacturing in Brazil since 1944.
