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:
Lifetime is evaluated under continuous 24-hour no-load operation, with both inlet and outlet open to atmosphere (ambient pressure conditions).
The standard BD-05TF250W configuration already uses a chemically resistant fluid path suited to more demanding dosing and liquid-transfer applications.
| Component | Material / Feature |
|---|---|
| Pump Head | PPS |
| Diaphragm | PTFE |
| Valve | FFKM |
Compared with conventional EPDM-based configurations, the PTFE diaphragm and FFKM valve provide a broader starting point for corrosive or chemically aggressive media. Final compatibility should still be verified against the actual liquid concentration, temperature, and service conditions.
For OEM projects with specific motor, material, or wiring requirements, selected components can be customized based on the standard BD-05TF250W platform.
| Item | Customization Options |
|---|---|
| Motor Type | Standard brushed DC motor; brushless DC motor available |
| Materials | Standard: PPS pump head, PTFE diaphragm, and FFKM valves; optional EPDM diaphragm and EPDM valves |
| Wiring | Custom cable length and wire configuration |
| Branding | Private label or customer-specific marking |
BODENFLO supports motor and material customization, wiring adjustments, and private labeling to meet specific OEM application requirements.
The BD-05TF250W is designed for compact fluid systems requiring low-flow delivery, self-priming, and chemical-resistant wetted materials. Its gas-liquid compatible design provides additional flexibility during fluid priming and replacement.
BODENFLO combines pump manufacturing, engineering support, and flexible OEM services to help customers develop fluid-handling solutions from prototype to production.
Typical OEM evaluation feedback for compact low-flow pumps usually focuses on material compatibility, priming behavior, and installation flexibility.
Application: Chemical-resistant ink and cleaning fluid transfer
Feedback: The compact body and PTFE / FFKM fluid path helped simplify pump selection for a small printer maintenance module.
Application: Reagent dosing and sample transfer
Feedback: The 250 mL/min flow range was suitable for controlled liquid movement without using an oversized pump.
Application: Sampling and cleaning fluid circuit
Feedback: The self-priming diaphragm structure provided useful tolerance when air temporarily entered the fluid line during operating cycles.
Inlet Protection and Fluid Path
Install a filter with filtration accuracy of ≤30 μm at the inlet to prevent particle ingress. Use ID4 mm / OD6 mm tubing and keep all connections sealed to reduce suction loss and priming problems.
Mounting
Bottom mounting uses 4 × Φ2.4 mm holes with 6.8 mm depth and M3 self-tapping screws. Side mounting uses 2 × R1.7 mm through holes with M3 screws for secure through-board installation.
Material and Operating Conditions
The standard liquid path uses PPS, PTFE, and FFKM. Confirm compatibility with the actual fluid before long-term operation. Ambient temperature should remain within 5°C to 40°C, with fluid temperature between 10°C and 60°C.

Actual flow can decrease because of liquid viscosity, inlet restriction, clogged filters, long tubing, small internal diameter, or outlet back pressure. For a miniature liquid pump, checking the complete fluid path is usually more useful than evaluating the pump flow alone.
Priming problems are commonly caused by air leakage, excessive inlet resistance, blocked filters, long tubing, or unsuitable installation height. BD-05TF250W has a 2 m reference water suction head, but actual performance depends on the working liquid and system layout.
The standard pump uses a PPS pump head, PTFE diaphragm, and FFKM valve, which provides a strong starting point for chemically demanding liquids. However, compatibility should be confirmed against the actual chemical, concentration, temperature, and required service life before final approval.
BODENFLO does not require a strict MOQ. Customers can begin with samples or small-batch orders for prototype testing and then scale to production quantities after performance and material compatibility are confirmed.
Yes. Related models can be selected according to required flow, pressure, motor type, and system size:
BODENFLO can help compare these models based on flow, pressure, liquid compatibility, suction height, operating life, and installation space.
If you are developing printing equipment, biochemical analyzers, chemical analysis systems, or compact dosing and sampling modules, BODENFLO can support pump selection, material review, prototype testing, and OEM integration.
