Technical summary
The FBCN (normalized centrifugal) line is specified in Tonantins, Amazonas for local industry — head up to 135 m, temperature up to 260°C. ASME B73.1, in-house manufacturing in Cabreúva-SP (3179 km).


Tonantins, Amazonas is territory where FB Bombas operates as a Brazilian industrial-pump manufacturer with 82 years of continuous operation. For the local industry industrial profile dominating the region, we offer the FBE, FBCN, FBOT and FBEI series with CRCC Petrobras qualification, API 676 compliance and ASME B73.1 normalization (API 610 engineered-to-order projects) — basis for retrofit in plants with global manufacturers already installed. For Tonantins, FB Bombas offers retrofit of existing baseplates — the FBCN centrifugal follows ASME B73.1, whose dimension designation is common to the entire installed normalized fleet, whoever the original manufacturer was. Membership in the Sudoeste Amazonense mesoregion (IBGE) places Tonantins in a regional economic mesh — a factor FB Bombas uses to optimize multi-city maintenance campaigns and consolidate freight across customers along the same axis. Tonantins is served by the BR-174 (via RR) / acesso fluvial axis and also by highways BR-174, BR-319 and BR-230 for heavy-cargo movement — relevant for delivery of mounted skids and large pump-and-motor sets. FB Bombas technical service in Tonantins covers centrifugal- and gear-pump sizing, commissioning support, assisted startup and operator training — a scope that spans the full technical-supply cycle. FB Bombas pumps installed in Tonantins, Amazonas meet CRCC Petrobras qualification, ASME B73.1 (centrifugal) and API 676 (gear) compliance — credentials FB has sustained as a Brazilian manufacturer since 1944. The fluid roster in Tonantins (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. From the Cabreúva-SP factory, 3179 km via BR-174 (via RR) / acesso fluvial, FB Bombas reaches Tonantins with FBE, FBCN, FBOT inventory and engineering capability for special projects.

Technical-and-commercial support for Tonantins is covered from Cabreúva-SP, with typical lead time for critical parts of 96h to 7 days via dedicated carrier. Recommended sealing for the operation profile in Tonantins is single cartridge mechanical seal (Plan 11/13) for general service, upgradable to dual when the fluid requires secondary containment — a choice that affects MTBF and maintenance procedure. Material selection for óleos industriais and água industrial in Tonantins 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 the technical profile observed in Tonantins, 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. FBCN sizing for the Tonantins circuit checks three points on the curve: the operating point (near BEP), available NPSH with margin over required — critical with hot fluid or suction lift — and end-of-curve power, which protects the motor against overload in off-design operation.
Demand in Tonantins is characterized by medium density — regular and predictable opportunity pipeline, a typical regional pattern of the mesoregion. Tonantins has a services-oriented economy (18.4% of value added, IBGE 2021; 2023 GDP of R$ 215 million) — in this profile, typical projects involve centrifugals for utilities, reservoirs and fire networks, with the FBCN as the reference series. Technically, Tonantins shows low complexity in its fluid mix — lean fluid roster — technical operation focused on few main vectors. Tonantins, among the 50 most populous cities in AM, maintains a relevant industrial base, sustains a predictable B2B demand chain — an ideal profile for scheduled supply and multi-year replacement contracts. In Tonantins, 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). Tonantins 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. For Tonantins, the FBFS line offers a complete fire-protection package: main pump, jockey, control panel NFPA 20 and diesel fuel tank — scope per NFPA 20.
The main logistics axis between Cabreúva-SP and Tonantins is BR-174 (via RR) / acesso fluvial, totaling 3179 km — a route that sets the default delivery time for finished equipment. Beyond the main route, Tonantins is accessible via BR-174, BR-319 and BR-230 — options that provide redundancy in case of blockages or restricted operating windows. Typical transit time to Tonantins: 72h to 7 days, depending on modal and dry season — the window used in FB Bombas' standard commercial commitment. Technical-service coverage for Tonantins involves technical visits planned as a mission — concentrated agenda to cover multiple plants in a single trip.

Brazilian sectors for which FB Bombas sizes equipment — complete technical guides per application.
Regional service from Tonantins — same series, same factory in Cabreúva/SP.
Yes. With a factory in Cabreúva/SP and a technical team dedicated to projects in Tonantins, FB Bombas has manufactured industrial pumps in Brazil since 1944. Applications currently running on imported equipment are covered by the FBCN (centrifugal), FBE/FBEI (gear) and FBOT (thermal oil) series — adding advantages in lead time (no import), factory-direct technical support, spare parts for FB pumps and application engineering that works in Portuguese. In a normalized-line retrofit, the interchangeability set out in ASME B73.1 holds between units of the same standard dimension designation, whatever the original supplier.
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.
Yes — and the secret lies in correct sizing, the main lever for energy efficiency. Both an oversized and an undersized pump waste energy. That is why FB Bombas engineering determines the optimal operating point from the actual process conditions in Tonantins, balancing the flow/pressure/power ratio.
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 Tonantins projects, application engineering supports commissioning with startup checklist, laser alignment and capture of the baseline vibration signature.
Lead time depends on the chosen series, construction materials and stock availability. For standard configuration pumps, lead times are shorter; for special or custom constructions, the schedule is informed in the technical proposal. Logistics for Tonantins is handled by our regular road operator.
Send the application data through the website form, WhatsApp +55 11 97287-4837 or email comercial@fbbombas.com.br: fluid (name and viscosity at operating temperature), target flow in m³/h, discharge head in m, available NPSH, operating temperature and regime — continuous or intermittent. After reviewing the briefing, application engineering returns a preliminary technical proposal, characteristic curve, suggested materials and delivery lead time for your project in Tonantins.
Yes — with a structural advantage: since the FBE, FBEI, FBCN and FBOT series are manufactured entirely in Brazil, parts ship from the factory itself in Cabreúva/SP, with short lead times for planned shutdowns and priority handling for emergencies. The direct effect is a lower total cost of ownership.
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 Tonantins 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.
