Gear pumps for projects in Araraquara, São Paulo

It depends on the mill circuit. For process water and other clean or turbid liquids, the FBCN; for viscous fluids, the FBE gear pump, whose catalogue cites syrups and molasses, and the FBEI, intended for high-viscosity liquids; and the FBOT only where there is a thermal oil circuit. Cane juice and vinasse with suspended solids call for consulting engineering, as the FBCN manual indicates. For the mill in Araraquara, state the circuit, fluid properties, temperature and the required flow and pressure; the series is confirmed for each circuit.

It depends on the series. The FBE can have packing, a mechanical seal, a lip seal or a magnetic coupling; the standard seal is type 21, in ceramic, graphite and Viton, with an AISI 304 stainless-steel spring. The FBCN uses packing or a mechanical seal, the FBOT combines graphite packing as the first sealing stage with a mechanical seal immersed in the bearing-housing oil, and the FBEI accepts packing or a single, double or cartridge mechanical seal. State the fluid, concentration, temperature and pressure of the process in Araraquara to define the arrangement.

Service is provided from the factory in Cabreúva, Brazil. For the project in Araraquara, provide the address, access conditions and delivery or visit needs. Costs, scheduling and timing depend on those conditions and confirmed availability, not only on distance between cities.

It depends on the series. On the FBCN and FBOT, back pull-out construction allows the bearing-housing assembly to be removed without disconnecting the piping, and the FBEI catalogue also indicates back pull-out construction. The FBE external gear pump is not back pull-out: its shafts are supported on bushings. Before working on the equipment in Araraquara, check the series manual, the sectional drawing and the parts list.

FB Bombas supplies the complete FBCN and checks, model by model, the dimensions in manual MTEC-03/00 (baseplate, nozzles, flanges and shaft) and the duty point before the order. The manual states mechanical construction per ASME B73.1; dimensional interchangeability with the existing pump is not assumed and is confirmed on the drawing. Send the identification and drawing of the pump installed in Araraquara, with flow, head, fluid, materials and drive.

The FBCN, a standardized centrifugal pump for clean or turbid liquids, with a series range of up to 2,200 m³/h and 135 m; when a higher head is required, the multistage FBME reaches 300 m. Each model has its own limits in the manual tables. For the project in Araraquara, state the fluid and the flow and head duty point; selection checks the model curve, suction conditions, materials, drive and installation interfaces.

Following the BNDES steps, first check whether the equipment appears on the list of items eligible for BNDES Finame financing, in the CFI Catalog on the bank’s website; for that check, ask the sales team for the identification of the model quoted for Araraquara. Then apply for financing through an accredited financial agent, such as a commercial bank, development bank, development agency or credit union. The agent reviews the request and, if it approves the operation, forwards it to BNDES, which evaluates the request and authorizes the financing. Being a Brazilian manufacturer does not, on its own, show that the equipment is accredited.

FB Bombas is a Brazilian manufacturer with direct service from its factory in Cabreúva. To compare an alternative for the project in Araraquara, check performance, materials, dimensions, documentation and commercial conditions. Brazilian origin alone does not guarantee lower cost, shorter lead time or technical equivalence.

It depends on the size. According to Table 2 of manual MTEC-01/01, the maximum is 2,500 SSU for sizes 1/8" to 1/4", 7,500 SSU for 3/8" to 1", 50,000 SSU for 1.1/2" to 2" and 100,000 SSU for 3" to 6". Speed decreases as viscosity rises: the drive is direct up to 7,500 SSU and, above that, by pulley or gear reducer, down to 150 rpm in the 50,000 to 100,000 SSU range. State the viscosity of the fluid for the project in Araraquara at start-up and operating temperatures so that engineering can confirm size and speed.

Yes. The FBOT is the FB Bombas series developed for pumping organic thermal oils. Manual MTEC-16/00 states temperatures up to 350 °C within the series range and back pull-out construction, which allows the bearing-housing assembly to be removed without disconnecting the piping; the maximum discharge pressure varies with temperature (Figure 1 of the manual), and the fluid must not contain abrasive particles. For the circuit in Araraquara, send the oil identification and technical data sheet, the start-up and operating temperatures and the flow and head duty point; model, materials and sealing are confirmed for the circuit.
