Selection support
Send operating data to select a pump line
Provide fluid, flow, pressure and temperature. Our team reviews the application and responds with a recommended pump line and supply terms.
Values are independent series limits: they are not a simultaneous operating point and do not apply to every model.
Compare the lines side by side
Compare published limits by series and consult the source document. To choose a model, check the curve and data sheet at the duty point.

Data for pump selection
Specify the fluid, duty point and installation conditions. Our team uses these data to compare pump lines for your operation.
Describe the fluid
Specify the product, viscosity at operating temperature and any solids. Include a technical data sheet if available.
- Viscosity in SSU or cP at operating temperature
- Minimum and maximum operating temperature
- Clean, turbid, solids-laden or abrasive fluid
- Compatibility: corrosive, toxic or flammable
In practice: For gear pumps, viscosity guides the pump size and speed. FBE speeds range from 1,750 down to 150 rpm with a pulley or reducer.
Define the duty point
Gather the required flow, pressure or head, temperature and suction conditions. Each model’s curves guide the assessment.
- Flow rate in m³/h or L/min
- Head or differential pressure
- NPSH available at suction, to prevent cavitation
- Continuous or intermittent duty
In practice: Compare the duty point with the model curve as well as the series limits. Maximum flow, pressure and temperature do not apply simultaneously.
Describe the installation
Indicate the drive, available space, materials and project requirements. For replacement, provide the existing model and nameplate details.
- Packing or mechanical seal
- Materials compatible with the fluid, by component
- Drive and scope: bare pump or assembly with motor, baseplate and coupling
- Special features, such as a heating chamber
In practice: Include the standards required by your project in the inquiry. They are reviewed for the series, configuration and requested scope.
Technical selection questions
What is the relationship between viscosity and speed in gear pumps?
FBE speed is selected according to size, viscosity and duty point. Depending on configuration, speed ranges from 1,750 down to 150 rpm with a pulley or reducer. FB Bombas Engineering limits viscosity by size (MTEC-01/01): 1/8–1/4 in., 2,500 SSU; 3/8–1 in., 7,500 SSU; 1.1/2–2 in., 50,000 SSU; 3–6 in., 100,000 SSU. Consult the model curve at operating temperature. View FBE series sizes.
When to use mechanical seal vs packing in industrial pumps?
Sealing must be selected for the fluid, temperature, pressure and solids content. FBE sealing options include packing, mechanical seals, lip seals and magnetic coupling (MTEC-01/01); the Type 21 seal uses ceramic and graphite faces with Viton. Consult FB Bombas for suspended solids. FBOT sealing uses graphite packing at the first stage and a mechanical seal in a cooler region. Verify the selected configuration; no mechanical seal should be presented as universally leak-free. View the technical manuals.
What is NPSH and why is it important for centrifugal pumps?
NPSH is the absolute total suction head above the head corresponding to the liquid vapor pressure, expressed in metres of pumped liquid. Compare installation NPSH available with the pump requirement and an appropriate service margin. NPSH3 corresponds to a 3% head drop caused by cavitation; merely exceeding it does not guarantee cavitation-free operation. For FBCN, use the model curve and consult engineering about suction, liquid and operating margin. Calculate NPSH available.
What construction materials does FB Bombas offer?
Materials must be specified by series, component and fluid compatibility. FBE materials are documented in Table 6 (MTEC-01/01): shafts run in TM23 bronze, graphite or PTFE bushings according to construction. Gears, shafts, casing and sealing have individual specifications; the material of one part does not describe the whole pump. Consult engineering for the selected configuration. View the FBE manual.
How do external and internal gear pumps differ?
FBE uses external gears, driving and driven, with shafts supported by bushings; in the documented construction (MTEC-01/01), sizes up to 1.1/2 in. use one helical pair, and 2 to 4 in. sizes use four double-helical gears. FBEI uses internal gearing with a rotor and an internal element, described in manual MAN001-10. Both series handle viscous fluids. Selection compares flow, pressure, viscosity, temperature, pulsation and suction conditions using each model curve; gear type alone does not establish pressure or efficiency superiority. View the FBEI manual.
How does the heating chamber work in asphalt pumps?
The CA heating chamber maintains fluid temperature in the pump by circulating a heating medium. CA is documented (MTEC-01/01) from 1.1/2 to 6 in.; sizes from 1/8 to 1 in. have no CA. Chamber temperature and operating conditions must be specified for the fluid and project. Consult engineering for asphalt, resins and other viscous fluids. See the gear pump for asphalt.
