The BD-05TFG3LB is designed for compact OEM fluid systems that require controlled liquid delivery against relatively high downstream resistance. Its magnetic-drive gear mechanism and brushless DC motor support smooth transfer in dosing equipment, analytical instruments, and chemical metering systems.
The pump combines a compact mechanical design with a 0–5V speed-control interface, allowing equipment designers to adjust motor speed for different operating requirements. It can be evaluated for liquid circuits incorporating filters, valves, and narrow tubing where the required working flow and pressure must be considered together.
The specifications below are organized to help you assess whether BD-05TFG3LB matches your system requirements.

For demanding OEM liquid handling applications, the standard material configuration provides a strong balance of wear resistance, chemical compatibility, and mechanical durability.
| Component | Material / Feature |
|---|---|
| Pump Body | 316L Stainless Steel with DLC Coating |
| Shaft | Tungsten Carbide |
| Gear | Tungsten Carbide |
| Shaft Bushings | Tungsten Carbide |
| Seal | PTFE |
The DLC-coated 316L pump body and tungsten carbide rotating components are especially useful where wear resistance and long-term dimensional stability matter. Compatibility with the actual working liquid should still be confirmed during sample testing.
For OEM projects, selected connection and integration details can be reviewed according to your equipment requirements.
| Item | Customization Options |
|---|---|
| Wiring | Custom cable length and wire configuration |
| Connector | Open leads or project-specific connectors |
| Branding | Private label or customer-specific marking |
| Integration | Fittings, tubing connections, and installation requirements |
BODENFLO can review these requirements during prototype development to simplify pump integration into your equipment.
If your application requires smooth, controllable liquid delivery with moderate pressure capability, the following examples can help you evaluate whether this model is a suitable fit.
For precision gear pump projects, nominal flow is only one part of the selection process. Liquid viscosity, outlet pressure, displacement, speed control, wetted materials, installation interfaces, and long-term sourcing all affect final system performance.
The following feedback reflects what OEM customers commonly value when integrating precision gear pumps into dosing and analytical equipment.
Application: Precision reagent dosing system
Feedback: The low-pulsation flow and adjustable speed range made it easier to tune liquid delivery for our analytical module.
Application: Chemical metering system
Feedback: The compact pump size and 5 bar pressure capability helped us integrate the liquid circuit without increasing the overall equipment footprint.
Application: Precision process-liquid transfer
Feedback: The DLC-coated stainless steel body and tungsten carbide components gave us a useful material option for long-cycle fluid handling.
Electrical Connection
Red wire: +24 V DC; black wire: Ground (GND); yellow wire: 0–5 V speed control input; blue wire: FG speed feedback output.
Fluid Path and Operating Limits
Use properly sealed G1/8 fittings and keep the fluid path clean. Confirm that liquid viscosity remains below 1500 cP and liquid temperature within 0°C to 80°C.
Material Compatibility
The standard wetted structure uses DLC-coated 316L stainless steel, tungsten carbide, and PTFE. Confirm compatibility with the actual liquid before long-term testing.

Final pricing, production lead time, and shipping time depend on the model, order quantity, customization requirements, and destination.
Yes. The pump supports 0–5V speed control over a specified 500–5000 rpm range, allowing motor speed to be adjusted for different liquid-transfer requirements. Actual flow varies with speed, viscosity, and differential pressure.
Theoretical flow = Displacement × Speed. With 0.65 mL/rev, the BD-05TFG3LB delivers a theoretical 1.95 L/min at 3000 rpm (0.65 × 3000 ÷ 1000). Actual flow may be lower due to internal leakage and operating pressure.
Yes, it supports speed-controlled liquid delivery for dosing applications. For accurate volumetric dosing, calibrate the delivered volume at the required speed, liquid viscosity, and working pressure.
A gear pump provides relatively smooth, low-pulsation flow and uses displacement and motor speed to estimate liquid delivery. A diaphragm pump is often preferable when self-priming, gas-liquid handling, or dry-running capability is required, provided the selected model supports those functions.
Choose BD-05TFG3LB for smooth, speed-controlled liquid transfer; consider a diaphragm pump when suction and mixed-phase handling are more important.
A magnetic drive gear pump transmits motor torque through magnetic coupling without a conventional rotating shaft seal penetrating the pump housing. A direct drive gear pump mechanically connects the motor and pump shaft and may require a dynamic shaft seal.
Magnetic drive is useful when reducing potential leakage at the drive-shaft interface is important. Chemical compatibility and operating limits still depend on the complete pump design.
Yes, the pump provides a 0–5V speed-control input and FG motor-speed feedback for OEM control integration. Use a compatible control interface and verify the input limits, FG output characteristics, and grounding requirements before connection.
Provide the liquid type, viscosity, required flow, working pressure, temperature, voltage, and operating duty cycle. Include tubing dimensions and filter or valve details when the fluid path has significant resistance. These details help determine the required operating point and suitable pump configuration.
