Industrial Gear Pumps

Gear pumps displace a theoretical volume per revolution. Delivered flow depends on speed and internal leakage, which is affected by viscosity and differential pressure. Selecting between gear and centrifugal pumps requires evaluating the liquid, duty point and predicted performance. FBE uses external gears; FBEI uses an internal-gear arrangement. To compare them, provide flow, differential pressure, temperature and viscosity under starting and operating conditions. Pulsation, material and sealing requirements must be confirmed for the selected configuration. Consult the manuals and send process data to engineering. A single viscosity value does not establish that one family suits every application.

FBE carries liquid between the external gear teeth and casing. Its catalogue presents materials, drives, drawings and flow and power tables by model, pressure and speed. The MTEC-01/01 manual adds viscosity, parts and construction data. The 2026 catalogue also lists the FBE 10″ on p.6. Previous manual ranges must not be extended to that configuration. Check the complete code, curve and proposed execution documents, especially for heating or replacement of an installed pump.

FBEI uses internal gears. The current catalogue presents HL, KK, LQ, LS, M and N configurations; MAN001-10 contains drawings and information for documented executions. Selection must relate hydraulic data to connections, materials, sealing and available space. Provide viscosity at operating temperature, flow, differential pressure and duty cycle. If the process requires pulsation, shear or dosing control, state the acceptance criterion. Compare performance at the proposed duty point rather than assuming a fixed efficiency for the entire range.

The catalogues list applications involving oils, fuels, resins, paints, asphalt, food fluids and other industrial liquids. Each duty needs the actual composition and startup and operating conditions; mentioning an industry does not establish suitability for all its processes. The guides below organize enquiries by fluid and function. For solids, corrosion, flammability, food contact or dosing, specify requirements and confirm the execution. Hydraulic oil transfer and hydraulic power generation are different duties requiring their own limits.

• Oils: transfer, circulation, filtration and lubrication.
• Asphalt: product, viscosity, heating and startup.
• Resins and paints: formulation, particles, cleaning and dosing.
• Food: FBE catalogue fluid, viscosity at pumping temperature and material.
• Fuels: composition, transfer conditions and area classification.
• Hydraulic circuits: function, flow and actual pressure.
• Chemicals: composition and material compatibility.
• Pulp and paper: liquid and solids characterization.
• Metallurgy: process-fluid or lubrication requirements.

FB Bombas started operations in 1944 and now manufactures in Cabreúva, Brazil. Discuss enquiries directly with sales and engineering. Confirm configuration, quantity, availability and dispatch for each supply. Compare proposals for the same duty point and scope: pump, drive, materials, sealing, accessories, tests and documents. Assess energy, maintenance, parts, installation and downtime using your operating data. Provide fluid, flow, pressure, temperature and viscosity. For replacement, include the nameplate, complete code and installation drawing. This allows performance and adaptations to be assessed before the proposal.
