The fluid roster in Grajaú (óleos comestíveis, água de processo and óleo térmico) demands attention to viscosity, operating temperature and chemical compatibility — variables that FB application engineering uses to recommend the proper series.
Grajaú: óleos comestíveis, água de processo and óleo térmico suggest materials such as austenitic stainless steels (AISI 304/316) with attention to thermal expansion — a choice impacting both durability and cost of the pump-and-motor set. In Grajaú, influence from the mineracao cluster translates into diluted slurries, process water with abrasive solids and slurry pumps when applicable — variables that enter both preliminary sizing and the selection of materials and constructive configurations. Technical fit in Grajaú points to FBEI and FBOT as the series suitable for typical local operations — a baseline recommendation; the final specification depends on the specific process parameters. For Grajaú (1949 km from Cabreúva-SP), the critical-parts logistics cycle runs in 96h to 7 days — a workable window for regular PM campaigns with controlled risk of extended downtime. The transferência de óleos, pasteurização and limpeza CIP set accounts for a large share of industrial demand in Grajaú; FB Bombas keeps documented history of analogous applications for sizing benchmarks. Before shipment to Grajaú, each pump is tested on a hydraulic bench with ISO 21940 G2.5 balancing — FB Bombas standard protocol.
Grajaú: medium fluid complexity, moderate fluid roster — concentration in a few main technical categories. At state scale, Grajaú belongs to the set of cities with relevant industrial scale in the state. Grajaú: by affinity to the mineracao cluster, 24/7 operation with annual scheduled outages — concentrated PM windows and continuous demand for critical parts — a variable that enters commercial planning. Grajaú: high industrial density — multiple plants in a small radius, meaningful cumulative demand — a variable influencing commercial strategy and service logistics. Typical fluids handled in Grajaú (óleos comestíveis, água de processo and óleo térmico) require careful selection of seal and coating materials — a central variable in pump sizing. pecuária operations in Grajaú demand continuous pumping of process fluids, with preventive-maintenance windows aligned to plant scheduled outages. Typical use cases identified for Grajaú: series FBEI for transferência de óleos and series FBOT for pasteurização and limpeza CIP. Grajaú, among the 50 most populous cities in MA, maintains a relevant industrial base, offers a continuous pipeline of technical opportunities — from retrofit to greenfield. The mineracao cluster near Grajaú brings applications such as process-water booster, slurry pumping, pit dewatering and tailings dam services — a repertoire FB Bombas serves with dedicated series and field-validated materials.
For Grajaú, 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. The BR-135, BR-222 and BR-316 mesh provides logistics redundancy for Grajaú — when one route is restricted (rains, construction, accidents), delivery is rerouted without compromising the critical lead time. For Grajaú, FB service follows the technical visits planned as a mission — concentrated agenda to cover multiple plants in a single trip model — application engineers conduct pre-scheduled visits while remote support via documentation and phone covers point queries. Cabreúva-SP → Grajaú via BR-135 (via Belém-Brasília BR-153) (1949 km): a corridor with regular FB freight history, supporting indivisible loads and sets with escort when the gauge demands. For Grajaú, 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.

Regional service from Grajaú — same series, same factory in Cabreúva/SP.
Service to Grajaú is handled directly by the FB Bombas team at the Cabreúva/SP factory — no intermediaries, no resellers. That means direct contact with application engineering for sizing, technical quotes returned within 24h and original spare parts supplied without distributor markup. On-site technical visits to Grajaú are planned based on project criticality.
Yes. In addition to the standard portfolio, FB Bombas develops custom solutions for special applications, including modifications in construction materials, sealing arrangements, integrated heating systems, skids, mobile assemblies and retrofit of existing installations. Special projects go through engineering before manufacturing.
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 Grajaú 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 Grajaú 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 Grajaú and surrounding areas. FB Bombas has been manufacturing in Brazil since 1944.
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 250°C with proper materials and sealing. Correct sizing of sealing and materials is essential for safe operation.
Yes. FB Bombas is a Brazilian manufacturer accredited in FINAME (BNDES Special Industrial Financing Agency), which qualifies equipment supplied to Grajaú 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.
FB Bombas manufactures three major lines: FBE (external gear) for viscous fluids, FBEI (internal gear) for lubricating fluids, FBCN (normalized centrifugal) for water and low-viscosity fluids, and FBOT (specific centrifugal) for thermal oil circuits. We also serve fire protection systems in compliance with NFPA and NBR 16704.
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 Grajaú. 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. FB Bombas serves Grajaú 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.
