Question 10

Does the FBE comply with the API 676 standard?

Accepted Answer

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. Flanges per ASME B16.1 125lbs (cast iron, standard on FBE 1.1/2" to 6"), ANSI B16.5 (carbon steel/stainless) or ASME B16.42 (ductile iron). Part numbering per DIN EN 24250 and hydraulic acceptance test bench.

Question 11

How does the FBE reach 350°C operating temperature with mechanical seal?

Accepted Answer

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.

Question 12

Is the FBE suitable for very high viscosity fluids such as asphalt and bitumen?

Accepted Answer

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.

Question 13

Is FB Bombas (FBE) qualified by CRCC Petrobras?

Accepted Answer

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. Active corporate registry 61.381.240/0001-78 publicly verifiable at Brazilian Federal Revenue. In continuous operation under the same corporate identity since 1944.

Question 14

What is the FBE lead time compared to an imported pump?

Accepted Answer

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.

Question 15

How to request technical quotation and the FBE technical manual?

Accepted Answer

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.

Question 16

Which standards and materials does the FBE technical manual cite for flanges, shaft, gears and sealing?

Accepted Answer

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.

Question 17

What is a gear pump?

Accepted Answer

A gear pump is a positive displacement pump that moves fluid through the meshing of two gears inside a casing. Each rotation displaces a fixed volume, producing continuous pulse-free flow independent of discharge pressure. FB Bombas manufactures the FBE series with 12 sizes from 1/8" to 6", per API 676.

Question 18

What is a gear pump used for?

Accepted Answer

A gear pump is used to transfer viscous fluids such as oils, asphalt, bitumen, resins, paints, chocolate, biodiesel and dense chemicals. It suits applications requiring constant flow independent of pressure and viscosity variations up to 100,000 SSU. FB Bombas FBE series operates up to 350°C with high-temperature sealing.

Question 19

How does a gear pump work?

Accepted Answer

A gear pump works through the synchronized rotation of two meshing gears inside a casing. When teeth separate on the suction side, they create partial vacuum that draws fluid in. The fluid is carried in chambers formed between teeth and casing to the discharge side, where teeth re-mesh and expel the fluid.

Question 20

When to use an external gear pump?

Accepted Answer

Use an external gear pump when pumping viscous fluids with constant flow and optimized cost. Suitable for lubricating and hydraulic oils, asphalt CAP, bitumen, biodiesel, vegetable oils, glycerin, resins, paints and chemical fluids with viscosity between 50 and 100,000 SSU. FB Bombas FBE handles 5 to 6,500 L/min and up to 350°C.

Question 21

Which pump to use for asphalt?

Accepted Answer

For asphalt CAP, bitumen, tar and heated binders use an external gear pump with heating jacket. FB Bombas supplies the FBE series in CA (Heating Chamber) version with thermal oil or steam circulating around the casing, keeping fluid at ideal temperature (140–180°C) and preventing solidification. Handles viscosities up to 100,000 SSU.

Question 22

Which pump to use for industrial diesel oil?

Accepted Answer

For industrial diesel oil transfer at high flow and pressure use FB Bombas FBE series external gear pump, sized per volume and distance. For fire protection with diesel engine driving centrifugal pump, use FBFS system per NFPA 20. For service-station distribution, 220V commercial pumps suffice.

Question 23

Which pump to use for resins and paints?

Accepted Answer

For epoxy, polyester, phenolic resins, industrial paints and varnishes use gear pumps. FB Bombas FBE series handles abrasive fluids with adjusted clearances; for resins with heavy fillers or shear sensitivity (latex), prefer FBEI (internal). Both support heating jacket for thermoplastic fluids and hot-melt adhesives.
