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 configuration is designed to balance chemical compatibility, structural stability, and service life in typical OEM applications.

BODENFLO also supports integrated OEM solutions including connectors, tubing, and mounting structures, enabling ready-to-install pump modules for UV ink and compact liquid systems.
The BD-05TF450W is commonly used in OEM fluidic systems where controlled micro-liquid transfer and gas-liquid compatibility are required in compact integration environments.
If your system involves mixed-phase fluid handling or intermittent liquid supply conditions, the following application examples can help you quickly evaluate technical fit.
In OEM equipment development, pump selection is not only about meeting basic performance data, but also about ensuring reliable integration, correct material matching, and stable transition from prototype to mass production. BODENFLO supports engineering teams throughout the entire development cycle, from early model selection to long-term supply planning.
We help align pump parameters such as flow, pressure, voltage, and installation space with real system operating conditions, reducing selection uncertainty at early design stages.
For UV ink, chemical, or sensitive fluid applications, we support evaluation of wetted materials to help reduce compatibility risks and improve long-term stability.
We provide practical integration options such as connectors, tubing interfaces, and mounting structures to simplify installation inside compact OEM equipment.
We assist customers during sample testing and system validation stages to help shorten iteration cycles and improve design confirmation efficiency.
For non-standard OEM platforms, voltage, structure, and interface configurations can be adjusted to better match system-level design requirements.
We support continuity from sample approval to mass production, helping OEM customers maintain consistent supply without interruption during project scaling.
The following feedback reflects how customers use similar pump solutions in real OEM systems and what they value most in actual applications beyond datasheet parameters.

Fluctuation is often caused by air presence in the inlet line, unstable suction conditions, or insufficient priming. Since this model is gas-liquid compatible, it can tolerate mixed-phase conditions, but inlet design and filtration still play a key role in maintaining consistent flow. A properly sealed system with correct tubing layout is recommended.
Priming issues usually come from excessive inlet resistance, air leakage, or improper installation height. The BD-05TF450W is self-priming, but performance depends on correct tubing size (ID4 mm recommended) and ensuring the inlet is not introducing air continuously during startup.
This model supports short-duration dry-running operation due to its diaphragm structure. However, continuous dry operation is not recommended, as it may accelerate wear of internal sealing components and reduce overall service life.
We provide a 1-year warranty for BODENFLO micro pumps.
Damage caused by incorrect operation, improper installation, or failure to follow the operation manual is not covered under warranty.
