The BD-05TF1400WBH is a 24V brushless micro diaphragm liquid pump designed for OEM equipment requiring controlled liquid transfer, self-priming, and pressure protection. With a maximum water flow of 1.4 L/min and a maximum water pressure of 3 bar, it supports fluid systems incorporating tubing, filters, and valves.
Its integrated top-mounted pressure-relief valve helps protect the pump head against excessive pressure, while PWM speed control and FG feedback support adjustable motor operation and speed monitoring.
The pump features a PPS pump head, PTFE diaphragm, and FFKM valves for applications involving compatible inks, reagents, and cleaning liquids. Its compact construction makes it suitable for integration into automated liquid-handling equipment.
The BD-05TF1400WBH features a top-mounted pressure-relief valve designed to help protect the pump head when outlet pressure becomes excessive.
In OEM liquid systems, pressure may increase because of restrictive filters, narrow tubing, closed valves, or temporary downstream blockage. The integrated valve provides an additional pressure-protection feature within the pump assembly.
The valve's operating characteristics should be considered together with the system's required working pressure and external pressure-protection design.
The following specifications help engineers evaluate liquid flow, pressure, suction capability, gas performance, materials, and integration requirements before sample testing.

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 BD-05TF1400WBH uses a chemically resistant fluid path intended for OEM applications where conventional general-purpose elastomers may not provide sufficient compatibility.
| Component | Material / Feature |
|---|---|
| Pump Head | PPS |
| Diaphragm | PTFE |
| Valve | FFKM |
| Pressure Protection | Integrated top-mounted pressure-relief valve |
PPS, PTFE, and FFKM provide a strong starting configuration for inks, reagents, cleaning fluids, and chemically demanding liquids. Final compatibility should still be confirmed using the actual chemical, concentration, temperature, and required operating life.
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.
The BD-05TF1400WBH is designed for OEM fluid systems requiring adjustable liquid delivery, self-priming, and pressure capability in a compact pump.
BODENFLO combines pump manufacturing, engineering support, and OEM services to help customers integrate miniature liquid pumps into their equipment.
The following examples reflect the factors OEM customers typically evaluate when integrating chemical-resistant gas-liquid diaphragm pumps into equipment.
Application: Reagent and cleaning-fluid transfer
Feedback: The 1.4 L/min flow and 3 bar pressure provided enough operating range for our fluid circuit, while the PTFE and FFKM components simplified material selection.
Application: Ink circulation and maintenance fluid transfer
Feedback: The brushless motor, PWM control, and pressure-relief structure made the pump easier to integrate into our controlled fluid platform.
Application: Chemical sampling and washing module
Feedback: The self-priming capability and gas-liquid compatible diaphragm design were useful when air occasionally entered the liquid path during operating cycles.
Install a filter with ≤30 μm filtration accuracy at the pump inlet to prevent particles from entering the pump chamber. Use ID6 mm / OD8 mm tubing and keep fluid connections properly sealed.
Drill 4 × Φ3.2 mm mounting holes at the bottom and secure the pump using M4 self-tapping screws or M4 screws.
Wiring definition:
For full-speed operation without external speed control, connect both the red and blue wires to positive (+), connect black to negative (-), and leave the yellow FG wire unconnected. BD-05TF1400WBH Liquid Pump Spec…
The standard fluid path uses PPS, PTFE, and FFKM. Ambient temperature is specified at 5°C to 40°C, while fluid temperature is 5°C to 60°C. Confirm chemical compatibility before extended operation.

Yes. The pump supports a 0–5V PWM speed-control input, allowing motor speed to be adjusted according to system requirements. Actual liquid flow depends on motor speed, working pressure, viscosity, and fluid-path resistance.
The integrated top-mounted pressure-relief valve helps protect the pump head from excessive outlet pressure caused by restricted flow or temporary downstream blockage. It provides additional pressure protection but does not replace proper system pressure control.
The 1.4 L/min flow and 3 bar pressure are separate maximum ratings, not a guaranteed simultaneous operating point. Actual flow decreases as outlet resistance increases. Refer to the flow–pressure curve when selecting the pump for a specific working pressure.
Yes. The pump has a specified 3 m water suction head, allowing it to draw water from a reservoir positioned below the pump. Actual suction performance depends on the liquid properties, tubing length, and inlet resistance.
Yes. BODENFLO offers several related brushless diaphragm pumps that cover different operating ranges:
BODENFLO can compare these models according to working medium, required flow, pressure, suction height, material compatibility, motor life, and installation space.
If you are developing digital printing equipment, biochemical analyzers, chemical analysis systems, sampling devices, or cleaning modules, BODENFLO can support pump selection, material review, fluid-system validation, and OEM integration.
