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).
For most OEM ink and liquid handling applications, the standard material configuration provides a practical balance of chemical compatibility, sealing performance, and long-term operation.
| Component | Material / Feature |
|---|---|
| Pump Head | PPS |
| Diaphragm | EPDM |
| Valve | EPDM |
The PPS pump head provides improved chemical and thermal resistance compared with common engineering plastics. If the standard EPDM configuration does not fully match the working medium, PTFE diaphragm and FFKM valve options can be evaluated for more corrosive liquids or gases.
For OEM printing and fluid handling projects, BODENFLO offers selected voltage, material, wiring, and integration options based on the standard BD-05TF850WB platform.
| Item | Customization Options |
|---|---|
| Voltage | 12V / 24V DC options |
| Materials | Optional PTFE diaphragm and FFKM valves |
| Wiring | Custom cable length and wire configuration |
| Connector | Open leads or project-specific connectors |
| Branding | Private label or customer-specific marking |
| Integration | Tubing, connectors, and installation accessories according to project requirements |
BODENFLO supports customized components and fluid-path integration to simplify prototype assembly and OEM equipment development.
The BD-05TF850WB is designed for compact OEM equipment requiring self-priming liquid transfer, moderate flow, and gas-liquid handling capability.
BODENFLO supports OEM manufacturers with pump selection, material configuration, prototype evaluation, and production supply for printing and fluid handling equipment.
The following feedback reflects what OEM customers value when integrating brushless liquid pumps into printing and analytical fluid systems.
Application: DOD ink circulation system
Feedback: The 850 mL/min flow range provided enough circulation for our ink path, while the compact pump size simplified installation inside the printer.
Application: Reagent and cleaning fluid module
Feedback: The self-priming capability and PPS pump head gave us a useful balance of fluid performance and material compatibility.
Application: Compact liquid circulation platform
Feedback: The brushless motor and 10000 h rated life matched our requirement for longer operating cycles with reduced maintenance.
Inlet Protection and Fluid Path
Install a ≤30 μm filter at the inlet to prevent particle ingress. Use ID4 mm / OD6 mm tubing and keep connections sealed to reduce leakage, pressure loss, and priming difficulty.
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.
Material and Operating Conditions
The standard configuration uses a PPS pump head with EPDM diaphragm and valve. Confirm compatibility with the actual ink or liquid before long-term operation. Ambient temperature is 5°C to 40°C, and fluid temperature is 10°C to 60°C.

Yes. The pump supports up to 850 mL/min water flow and 3.5 L/min free gas flow, with a maximum gas vacuum of −50 kPa. These are separate performance ratings.
The brushless motor has a specified 10,000-hour service life under no-load continuous-operation testing. Continuous operation in an ink circuit should be evaluated at the actual liquid pressure, temperature, and duty cycle.
Unstable performance can result from air leakage, intermittent liquid supply, filter resistance, trapped air, or excessive tubing restriction. Because BD-05TF850WB is a gas liquid diaphragm pump, checking both the liquid path and gas leakage points is important when diagnosing unstable circulation or suction.
The gas-liquid compatible diaphragm design allows the pump to transfer both air and liquid. However, air bubbles can still affect printhead performance, so a suitable degassing or air-removal arrangement may be required.
Yes. BODENFLO offers several related models for OEM fluid systems with different performance priorities:
BODENFLO can help compare these models based on working medium, required flow, pressure, suction height, material compatibility, and installation space.
If you are developing DOD printers, ink circulation systems, biochemical analyzers, or compact OEM fluid handling equipment, BODENFLO can support pump selection, material review, customization, sample testing, and long-term supply.
