External Gear Pump — SeriesFBE

FBE series gear pumps are ideal for viscous fluids such as lubricating oils, resins, paints, adhesives, chocolate, asphalt, bitumen and various chemicals. They handle viscosities up to 100,000 SSU. For abrasive fluids with suspended solids, consult the application engineering team.

FBE series gear pumps offer flow rates from 0.5 to 6,500 L/min (up to 390 m³/h) depending on the model and speed. The 12 nominal sizes range from 1/8" to 6" to meet different industrial needs.

The maximum discharge pressure of FBE pumps is 22 kgf/cm² (≈ 22 bar). The actual value depends on the chosen size, fluid viscosity and operating speed. FB Bombas engineering validates the duty point against the shaft power curve of the selected model to ensure bearing and seal service life.

The FBE series covers 12 nominal sizes — 1/8", 1/4", 3/8", 1/2", 3/4", 1", 1.1/2", 2", 3", 4", 5" and 6". The 5" and 6" sizes are made to order. Each size has construction variants (standard, valved and CA — with heating chamber) selected according to the fluid and process conditions.

Yes, for bulk transfer of food products — chocolate, vegetable oils, molasses and additives. For these applications the FBE is supplied in 316 stainless steel (ASTM A743 CF8M), a material suitable for food contact, with sealing compatible with the product. Material selection and finish are defined by the application engineering team according to the fluid; this is transfer pumping, not aseptic CIP/SIP processing.

Centrifugal pumps lose efficiency rapidly above 100 cP viscosity — flow drops and required NPSH rises. The FBE gear pump is positive displacement: flow proportional to speed, practically independent of pressure. For oils, asphalt and resins above 100 cP, the gear pump delivers constant flow with lower energy consumption than the equivalent centrifugal.

In the FBE code, "FBE" is the series (external gear pump) and the number is the nominal port size in inches (1/8" to 6"). The suffixes describe the gear: A = larger-diameter gear, D = longer gear, DA = greater length and module, and M6/M8/M9/M12 = gear module; CA means integrated heating chamber and STD the standard configuration. The main components are the body (casing), a pair of helical gears, shafts, self-lubricating TM23 bronze bearings, covers and sealing (packing or mechanical seal). Example: FBE-3-M9 is a 3" pump with gear module 9.

Material choice follows the fluid and process. Cast iron ASTM A48 is the economical standard for oils, asphalt and fuels. Carbon steel ASTM A216 WCB handles higher pressure and heated fluids. Stainless ASTM A743 CF8M (316 equivalent) suits chemically aggressive, corrosive fluids and bulk food-product transfer. Bronze ASTM B584 is used in specific compatibility applications. The application engineering team defines the material per chemical compatibility, temperature and working pressure.

The FBE catalogs viscosity in SSU (Saybolt Universal Seconds) and operates up to 100,000 SSU. To convert to cSt (centistokes), above ~75 cSt the practical rule is cSt ≈ SSU ÷ 4.6 (and SSU ≈ cSt × 4.6). Examples: 100,000 SSU ≈ 22,000 cSt; 5,000 SSU ≈ 1,090 cSt; 500 SSU ≈ 108 cSt. Always state the viscosity at the actual pumping temperature — it drops as the fluid is heated — so the application engineering team can size speed and power correctly.

Yes. The FBE line is built per API 676 — Positive Displacement Pumps — Rotary, the American Petroleum Institute standard for rotary positive-displacement pumps used in refining and petrochemicals. The 12 catalogued sizes (1/8" to 6") follow the helical external gear principle, with sealing by packing or mechanical seal, self-lubricating TM23 bronze bearings and construction in four materials: cast iron ASTM A48, carbon steel ASTM A216, stainless ASTM A743 or bronze ASTM B584.

Part numbering per DIN EN 24250 and hydraulic acceptance test bench.

The FBE operates up to 350°C with appropriate seal configuration and optional heating chamber (CA suffix) integrated in the casing — double chamber cast as a single piece, compatible with thermal oil, saturated steam or superheated water. The chamber is ordered for any fluid that needs to be heated or kept at temperature during pumping — not just asphalt. Typical application includes products that solidify, crystallize or sharply increase viscosity below operating temperature. C1/C2 BSP chamber connections sized per pump bore.

Yes. The FBE pumps fluids from very low to very high viscosity — up to 100,000 SSU (≈ 22,000 cSt) with appropriate reduced-RPM configuration. For any fluid that needs to be heated or kept at temperature during pumping (asphalt, bitumen, polymers, chocolate, waxes, resins, BPF, thermal oil, among others), the CA (Heating Chamber) optional is ordered together with the base model. Helical gears for quiet operation, oversized bearings, precise axial clearance adjustment. The application engineering team sizes the motor/reducer set per the pump performance curve and fluid viscosity.

Yes. FB Bombas is a qualified supplier in Petrobras' Cadastro de Registro Cadastral de Contratados (CRCC) under Family 6 — Rotating Equipment, eligible to supply industrial pumps (including the FBE line) for Brazilian Oil & Gas projects.

FBE lead time is defined case by case by the application engineering team in Cabreúva-SP, considering size (among the 12 catalogued from 1/8" to 6"), construction variant (standard, valved or CA — Heating Chamber), materials (cast iron ASTM A48, carbon steel ASTM A216, stainless ASTM A743 or bronze ASTM B584) and sealing type. Because manufacturing is fully Brazilian — in-house CNC machining and assembly with hydraulic test bench — lead times tend to be significantly shorter than equivalent imported pumps, with no dependency on international logistics.

The FBE technical quotation is requested directly from the application engineering team. Provide the fluid (with viscosity and temperature), required flow, discharge pressure, available NPSH, desired materials and whether the application requires the CA (Heating Chamber) variant. The FBE technical manual — with performance curves, dimensions of all 12 sizes, sealing options and materials — is available at /en/technical-manuals/fbe in Portuguese, English and Spanish, free for download in PDF.

The FBE technical manual (MTEC-01/01) defines the construction, materials and standards specification of the external gear pump line. FBE pumps from 1.1/2" to 6" carry the flanges as part of the casing itself per ASME B16.1 125lbs for cast iron; for other classes and standards, specification follows the material employed and the fluid application. Optional shaft materials may be SAE 8620 and gears SAE 8640, or other types specified per application. Standard sealing is type 21 mechanical seal with ceramic × graphite × viton, with optional alternative material combinations per fluid. Coupling protection is FB standard in carbon steel or anti-spark material. Part numbering per DIN EN 24250. The full manual with the performance table of all 12 sizes (1/8" to 6"), parts lists per configuration (with packing, with mechanical seal, with CA heating chamber, with external bearing) and sectional drawings is available at /en/technical-manuals/fbe in Portuguese, English and Spanish, free for download in PDF.
