External gear pump FBE Series

The FBE handles applications with oils, resins, paints, asphalt, molasses and other industrial fluids. Suitability depends on composition, viscosity at operating temperature and material compatibility. State whether solids or abrasives are present and provide suction conditions to assess the model and configuration.

Read flow from the model table together with speed and discharge pressure. FB Bombas Engineering lists up to 390 m³/h for the series, with distinct configurations, and the 2026 catalogue p.6 also lists the 10″; larger models are made to order. Published specifications preserve each record's identity; request selection for new configurations from FB Bombas engineering.

The series has a general limit of up to 22 kgf/cm². Each model's duty point depends on viscosity, speed, power and the selected configuration. This does not mean that every pump delivers the series' highest flow, pressure and temperature simultaneously.

The website provides 20 records across 12 nominal sizes, from 1/8″ to 6″, including variants with individual specifications. The 2026 catalogue also lists the 10″ on p.6, and larger models are made to order. Check the full code and accessories for the model: a listed size does not establish every combination of valve, heating, material and seal.

Selection between gear and centrifugal pumps depends on flow, pressure or head, viscosity at operating temperature, suction conditions and materials. FBE and FBEI serve viscous fluids; FBCN serves centrifugal applications and FBOT thermal oil circuits. There is no universal 100 cP threshold: compare corrected curves, internal losses and power at the same duty point with engineering.

FBE identifies the external gear series; the dimension in inches identifies the nominal port size. Letters and suffixes belong to the specific model identity and should accompany your enquiry. Use the full code, drawing and pump nameplate for replacement, without inferring dimensions or interchangeability from port size alone.

The FBE casing and covers are ASTM A48 CL30 cast iron, ASTM A536 60-40-18 ductile iron, ASTM A216 WCB carbon steel or ASTM A743 CF8M stainless steel. A bronze configuration is also available, whose specification must be confirmed in the quotation. Selection considers fluid compatibility with each component, temperature, pressure and sealing.

Provide viscosity with its unit and measurement temperature. Conversion between Saybolt Universal seconds and kinematic viscosity in cSt requires a table or applicable procedure, such as ASTM D2161, at the same temperature. A conversion table is available for the FBE; dividing by a fixed number does not replace that reference or technical selection.

The FBE uses two external gears to transfer fluids such as oils, asphalt, resins, paints and molasses. The series covers viscosities from 30 to 100,000 SSU, with specific models and speeds for each range. Selection combines the fluid and its temperature with the flow, pressure and materials required by the process.

The FBE includes asphalt among its applications and offers a heating chamber as an accessory, depending on the configuration. Provide startup and operating temperatures to assess the model, seal and heating arrangement.

In the FBE, two externally toothed gears carry the fluid between their teeth and the casing. The FBEI uses a gear-within-a-gear arrangement. Each series has its own documentation: compare the duty point, viscosity at operating temperature, materials and sealing without transferring limits or accessories from one series to the other.

On the FBE, stainless steel casings and covers are ASTM A743 CF8M, and AISI 316L is one option for shafts and gears. Components must be specified individually. Provide fluid composition and concentration, temperature and pressure to assess material and seal compatibility.

Fuels and solvents are among the FBE applications. FBE sealing options are packing, mechanical seal and lip seal; selection depends on the fluid and operating conditions. State containment and safety requirements to define the configuration, without assuming a double seal, cartridge seal or leak-free operation as standard features.

Read the FBE speed-versus-viscosity table together with the models listed in each row. For example, it includes the FBE 1″ at 1,750 rpm for 30 to 250 SSU and the 3″, 4″, 5″ and 6″ sizes between 300 and 150 rpm for 50,000 to 100,000 SSU. Confirm the variant and drive power for the duty point.

The series range is 10 °C to 500 °C. For the mechanical seal, the temperature follows the seal manufacturer’s recommendation, and the series range does not establish that every seal or model can operate at that temperature. The thermal configuration depends on the fluid, materials, seal and startup and operating conditions.

Asphalt and bitumen require selection using viscosity at the actual pumping temperature. The 50,000 to 100,000 SSU range corresponds to the 3″, 4″, 5″ and 6″ sizes at 300 to 150 rpm. Assessment also considers suction supply, drive and heating requirements; this range is not a universal rating for every variant.

FB Bombas reports a registration in the Petrobras supplier registry. Petrobras issues the Certificado de Registro Cadastral (CRC), which replaces the former CRCC, to suppliers that meet one or more criteria of the supply family of interest; it is a supplier registration, not a product certification. Validity and supply families must be checked on the current certificate, provided on request.

For purchases that require the registration, check the scope required by the project on the certificate.

FBE pumps from 1/8″ to 4″ are in stock in Cabreúva-SP, in all configurations and options: 18 of the 20 catalog models. For FBE 5″ and 6″, check availability. This stock statement applies only to the FBE series.

Provide fluid, viscosity and temperature, flow, discharge pressure, suction conditions and material, seal and heating requirements. For replacement, include pump identification and the existing configuration. The Portuguese FBE technical manual is available on the FBE technical manual page; the page also gathers series documentation to support your enquiry.

The FBE has BSP connections from 1/8″ to 1″ and ANSI B16.5 150 lb flanges from 1.1/2″ to 10″. It uses SAE 1045 or AISI 316L for shafts and gears, and packing, mechanical seal or lip seal for sealing. Confirm the supplied configuration's drawing and documentation before specifying connections and components.
