Water Flow Measurement:
Water flow is measured using a high-precision miniature electromagnetic flowmeter (electromagnetic induction volumetric flowmeter).
The test setup includes approximately 1 m inlet and outlet tubing to simulate practical installation conditions.
Noise Measurement:
Noise is measured at a distance of 1 m from the pump during normal operation under standard working conditions.
Lifetime Testing:
The 10,000-hour rated lifetime is evaluated under continuous no-load operation with the inlet and outlet open to atmosphere. Actual service life may vary with pressure, duty cycle, medium, temperature, and operating conditions.
For most OEM applications, the standard material configuration provides a practical balance of chemical compatibility, sealing performance, and long-term operation.
| Component | Material / Feature |
|---|---|
| Pump Head | PA66 |
| Diaphragm | PTFE |
| Valve | FPM(FKM) |
The PTFE diaphragm and FPM valve provide a stronger starting point for applications involving demanding fluids than a basic EPDM configuration. For more aggressive media, a PPS pump head and FFPM valve configuration can also be evaluated.
When the standard configuration does not fully match your equipment design, selected connection and integration details can be customized for OEM applications.
| Item | Customization Options |
|---|---|
| Wiring | Custom cable length and wire configuration |
| Connector | Open leads, plug connectors, or OEM-specific interface |
| Branding | Private label or customer-specific marking |
| Integration | Tubing connection and installation requirements can be reviewed according to equipment layout |
BODENFLO can review wiring, connectors, tubing connections, and installation requirements during prototype development to help reduce additional sourcing and integration work.
If your application requires controlled liquid transfer with strong self-priming and gas-liquid compatibility, the following examples can help you evaluate whether this model is a suitable fit.
For medical, printing, and analytical fluid systems, pump selection involves more than nominal flow. Medium compatibility, suction height, pressure loss, duty cycle, tubing resistance, and installation space can all affect actual system performance.
The following feedback reflects how customers use BD-05TF450WBD in OEM fluid handling equipment and what they value most during integration.
Application: Compact suction and fluid transfer module
Feedback: The strong self-priming capability and brushless motor made the pump a practical fit for our compact fluid system.
Application: Ink and cleaning fluid handling system
Feedback: The pump integrates easily into our printing platform and provides useful pressure for moving fluid through filters and tubing.
Application: Reagent and liquid sampling module
Feedback: The PTFE diaphragm and compact structure helped us balance material compatibility, pump size, and long operating cycles.
Inlet Protection and Fluid Path
Install a ≤30 μm inlet filter to prevent particle ingress. Use ID4 mm / OD6 mm tubing and keep connections sealed to reduce leakage, pressure loss, and priming difficulty.
Mounting and Control
Secure the pump using the 2 × M3 threaded mounting holes on the base. Red wire is positive, black wire negative, blue wire provides 0–5 V PWM speed control, and yellow wire provides FG frequency/speed output.
Material and Operating Conditions
The standard configuration uses a PA66 pump head, PTFE diaphragm, and FPM valve. Confirm compatibility for special liquids or gases. Ambient temperature is 5°C to 40°C, and fluid temperature is 10°C to 60°C.

The standard fluid path uses a PA66 pump head, PTFE diaphragm, and FPM valve, making the pump suitable for many compatible reagents, inks, cleaning fluids, samples, and process liquids. For more chemically demanding media, PPS and FFPM options can be evaluated. Final compatibility should be confirmed with the actual liquid.
Yes. BD-05TF450WBD provides a 7 m reference water suction head and self-priming capability. Actual suction performance depends on liquid viscosity, tubing diameter and length, inlet sealing, filters, fittings, and vertical installation height.
The brushless motor has a rated lifetime of 10,000 hours under the specified no-load lifetime test conditions. Actual service life depends on working pressure, duty cycle, medium, temperature, speed, and system resistance, so continuous-duty applications should be evaluated under the intended operating conditions.
Yes. BD-05TF450WBD supports 0–5 V PWM speed control and provides an FG speed feedback signal, allowing OEM equipment to adjust pump speed and monitor motor operation as part of the control system.
Provide the working liquid, required flow and pressure, suction height, viscosity, liquid temperature, tubing dimensions and length, filters or valves, duty cycle, available voltage, control requirements, and installation space. These conditions allow BODENFLO to evaluate the pump against the actual fluid circuit.
