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. 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. ASME B73.1 for horizontal normalized centrifugal pumps — consolidated market standard: this is the normative package applied in Grajaú — defining acceptance testing, dimensional tolerances, material requirements and the Data Book delivered to the customer. In utilities and continuous process in Grajaú, the standardized centrifugal standardizes the fleet: 53 models with bench-tested curves cover the flow × head grid, and the same construction philosophy simplifies spares inventory across sizes — fewer critical items, more availability.
The demand profile in Grajaú reflects high industrial density — multiple plants in a small radius, meaningful cumulative demand. The economic fabric of Grajaú is diversified: services lead, but industry holds 20.3% of municipal value added (IBGE, 2021), over a 2023 GDP of R$ 1.4 billion — real demand for both process pumps and building utilities and sanitation. Typical seasonality of the mineracao cluster (24/7 operation with annual scheduled outages — concentrated PM windows and continuous demand for critical parts) directly impacts supply scheduling and PMs in Grajaú. Economically, delivery to Grajaú brings logistics is a significant economic factor — order consolidation and integrated packages are recommended. pecuária plants in Grajaú sustain a continuous pipeline of technical demand — from scheduled replacement to ASME B73.1 dimensional retrofit replacing imported equipment. Given its state-level scale (among the 50 most populous cities in MA, maintains a relevant industrial base), Grajaú concentrates projects of varying complexity — making room for both standardized ASME B73.1 solutions and engineered-to-order. For Grajaú, special solutions include ASME B73.1 dimensional retrofit with flange and footprint interchangeability, modular skids with integrated automation and mobile sets for decommissioning campaigns. The mineracao cluster around Grajaú concentrates applications process-water booster, slurry pumping, pit dewatering and tailings dam services — a technical package where FB Bombas has commissioning, retrofit and long-term support history. In Grajaú, FBFS fire-protection projects serve industrial buildings, commercial spaces and logistics warehouses with approval for state Fire Department and insurers.
1949 km separate the Cabreúva-SP factory from Grajaú via BR-135 (via Belém-Brasília BR-153) — an axis sized for movement of pumps, skids and pump-and-motor sets. Logistics lead time to Grajaú is 72h to 7 days, depending on modal and dry season — variable with cargo type, season and specific optimizations. On projects for Grajaú, logistics may include multimodal consolidation — a relevant alternative for large equipment or tight deadlines. Alternative routing to Grajaú can use BR-135, BR-222 and BR-316, which helps in heavy-traffic situations or maintenance on specific roads. The technical-service model in Grajaú is structured as technical visits planned as a mission — concentrated agenda to cover multiple plants in a single trip.

FB Bombas manufactures four 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 design of the FBE and FBCN lines favors direct access to wear-prone components — disassembly and inspection are done with conventional tools. The routine gets even simpler with detailed technical manuals and replacement parts supplied straight from the factory.
The FB portfolio handles an extensive spectrum of fluids. The FBE series takes mineral and synthetic oils, asphalt (CAP), BPF fuel oils, petroleum derivatives, molasses, resins plus viscous chemical and hydraulic products; the FBCN series works with raw and treated water, process fluids and industrial effluents; the FBOT series is dedicated to thermal oil at elevated temperatures. Each case is sized considering viscosity, temperature and chemical compatibility.
They are. For each delivery to Grajaú, FB Bombas assembles the unit's complete technical Data Book, containing: hydraulic test certificate, material certificates — stainless steel, duplex or ductile cast iron, per spec —, ISO 21940 G2.5 balancing report, characteristic curve obtained on the bench, API 682 mechanical-seal data sheets, operation and maintenance manual and as-built drawings. Full traceability happens through the serial number.
Yes. FB Bombas serves the entire metropolitan region and microregions neighboring Grajaú with the same technical support and logistics structure. This regional reach allows serving industrial plants distributed across multiple cities in a coordinated way.
It is. From the data of the pump in operation (flow, pressure, viscosity, temperature), FB Bombas' application engineering proposes a technical equivalence — dimensional or functional — with one of our series. This replacement has already been done by many clients in Grajaú, with benefits in lead time, cost and local support.
