Industrial pumps for projects in Rio Vermelho, Minas Gerais

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 Rio Vermelho. 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.

The catalogue includes FBE external gear, FBEI internal gear, FBCN standardized centrifugal, FBME multistage centrifugal and FBOT thermal oil pumps, fire systems and custom solutions. Review each family’s documentation; configuration and availability are confirmed in the quotation.

No: manual MTEC-03/00 states mechanical construction per ASME B73.1, not dimensional compliance with that standard. So, before a replacement in Rio Vermelho, interchangeability with the existing pump is checked on each model’s drawing, together with the duty point, materials and drive.

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 Rio Vermelho to define the arrangement.

The published grade is for the FBME: service manual MSERV-08/01 (item 12.2) specifies static and dynamic impeller balancing to grade G6.3. The manuals of the other series do not publish a grade; for them and for critical projects in Rio Vermelho, specify the required standard, grade and report in the purchase scope. Impeller balancing alone does not guarantee the vibration level of the installation.

With the pump and part identification. State the pump model and identification, the part as shown in the parts list of the series manual, the urgency and the destination in Rio Vermelho; the team checks availability and confirms service and transport options. There is no published universal parts lead time or automatic guarantee of consignment stock. To reduce downtime, the FBEI (MAN001-10) and FBME (MSERV-08/01) manuals include the list of spare parts for two years of operation.

When the Data Book is part of the purchase scope. State which drawings, manuals, certificates and test reports are required for Rio Vermelho; the proposal confirms the documents applicable to the supplied series and configuration. The same Data Book is not assumed for every pump.

It depends on the model and the duty point; there is no single efficiency figure for the brand. The FBCN and FBME characteristic curves show the efficiency of each model and, for stainless-steel impellers with passages up to 15 mm, the FBCN manual deducts 2 or 3 points from the curve efficiency (Table 4). For the project in Rio Vermelho, compare the absorbed power at the process flow, head and fluid, also considering drive, control and operating duty.

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 Rio Vermelho, check the series manual, the sectional drawing and the parts list.

It depends on the series. The catalogue for the FBE external gear pump lists oils in general, greases, asphalt, diesel oil, kerosene, paints, varnishes, resins and solvents, as well as lubrication systems and hydraulic equipment. The FBEI internal gear pump is intended for high-viscosity liquids. The FBCN and FBME handle clean or turbid liquids, and the FBOT handles organic thermal oils free of abrasive particles and of substances that chemically attack the pump. For the process in Rio Vermelho, state the composition, temperature, viscosity and solids content; fluids with suspended solids must be assessed by FB engineering.
