The final configuration depends on the fluid and operating conditions. Materials and options below describe available supply configurations.
Material options by component
Construction options for the FBE series. Each component material, seal and accessory is selected for the fluid and operating conditions. Confirm the available configuration for the model in the supply specification.
- Casing and covers
- ASTM A48 CL30 cast iron, ASTM A536 60-40-18 ductile iron, ASTM A216 WCB carbon steel or ASTM A743 CF8M stainless steel.
- Shafts and gears
- SAE 1045 steel or AISI 316L stainless steel. Special treatments on request.
- Bushings
- Self-lubricating bronze, cast iron, PTFE (Teflon), graphite or white metal.

Specify the assembly for the operating conditions
Fluid and duty point
Provide the fluid, flow, differential pressure, temperature and viscosity at pumping conditions. Review these together with speed and suction conditions. Also state the supply frequency (50 or 60 Hz): a gear pump moves a volume of liquid with each shaft revolution, so the flow depends on the speed set by the motor and drive.
Sealing and materials
Confirm each component material and the seal for the configuration. Packing, mechanical seals and lip seals are series options; availability depends on the supplied configuration.
Heating
The CA heating chamber is not available at this connection size.
Assess each limit for the model and configuration, without assuming simultaneous maxima. Before installation, confirm connections, flange class, sealing and the dimensional drawing.

Selection conditions for this model
The FBE 1" D serves continuous processes, high viscosity fluids, industrial production. For this connection diameter, Table 2 (MTEC-01/01) reaches 7,500 SSU, at 850–1,750 rpm; the more viscous the fluid, the lower the speed. The CA heating chamber is offered only from 1.1/2″ up. This connection diameter has 4 models: code FBE-1-D identifies the curves, materials and options of the same configuration.
Questions about the FBE 1" D.
What is the reference flow for the FBE 1" D?
The published reference for this model is 88.6 L/min, with a maximum speed of 1,750 rpm. Check the flow at the required discharge pressure in the model table or in MTEC-01/01. Maximum flow and maximum pressure are separate limits, not one duty point.
Can the FBE 1" D have a heating chamber?
The CA heating chamber is not available at this connection diameter. It is offered on FBE pumps from 1.1/2″ to 6″. If the fluid must be kept heated, discuss the configuration with FB Bombas engineering.
What should I provide to specify the FBE 1" D?
Provide the fluid, required flow, differential pressure, operating temperature and viscosity. The published viscosity limit for this connection diameter is 7,500 SSU; speed, materials and sealing must be selected for the actual service. Include suction conditions and the intended drive.
Is the FBE 1" D in stock?
Yes: the FBE 1" D is kept in stock in Cabreúva-SP, in every configuration and option. Request a quotation using code FBE-1-D; FB Bombas confirms the quantity available, the pricing and the dimensional drawing for supply. Existing dimensional files cover specific arrangements; check the variant and connections before defining the installation.
How many gears does the FBE 1" D have?
Per Table 5 (MTEC-01/01), the FBE 1" D uses two helical gears, one drive and one driven, with a 49 mm gear diameter, 100 mm gear length and 11 teeth, on a 15.87 mm standard shaft. Rotation is clockwise with a counter-clockwise option, viewed from the drive end.
Which speed suits the FBE 1" D for each viscosity?
Table 2 (MTEC-01/01) sets the speed by viscosity for this connection diameter: 30–250 SSU: 1,750 rpm (direct), 250–2,500 SSU: 1,150 rpm (direct) and 2,500–7,500 SSU: 850 rpm (direct). Above the direct-drive range, a pulley or gear reducer lowers the speed; the duty point and the curve confirm the final choice.
Which spare parts make up the FBE 1" D?
In the packed construction, Table 9 (MTEC-01/01) lists 18 items numbered per DIN EN 24250, starting with casing, front cover, rear cover, drive shaft, driven shaft and gasket (cover / casing). The mechanical seal, lip seal, external bearing and relief valve options have their own parts lists. Quote code FBE-1-D and the part number when requesting spares.
