Overview of BD-05TF3200WB Liquid Diaphragm Pump

The BD-05TF3200WB is a liquid diaphragm pump designed for OEM gas-liquid handling systems that require high water flow, compact integration, and brushless motor operation. It supports both liquid transfer and gas movement, making it suitable for equipment where one pump platform needs to manage fluid circulation, cleaning, sampling, or auxiliary gas handling.

With 3200 mL/min water flow, 10 bar max water pressure, and 6 L/min gas flow, this model is suitable for higher-flow fluid systems. For practical OEM use, the datasheet recommends operation within 2 bar, so engineers should evaluate the working pressure, tubing resistance, and duty cycle during sample testing.

Testing Conditions & Measurement Standards

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).

Standard Materials & Reliability

The standard wetted material configuration is designed for gas-liquid transfer applications where flow capacity, sealing performance, and chemical compatibility need to be balanced. PA66 provides a practical pump head material, EPDM is used for the diaphragm, and PTFE is used for the valve to support improved fluid compatibility.

Component Material / Feature
Pump Head PA66
Diaphragm EPDM
Valve PTFE
Motor DC Brushless Motor
Operation Oil-free, self-priming, dry-running capable
Lifetime 10000 h

For more demanding liquids or gases, material compatibility should be confirmed before sample testing. Optional material configurations such as PTFE diaphragm or FFPM valve options can be discussed for applications involving corrosive media or stricter chemical resistance requirements.

OEM Customization Options

If the standard version does not fully match your system design, BODENFLO can support selected customization items for OEM integration.

Item Customization Options

Installation & Usage Notes

Proper installation helps maintain stable liquid flow, gas performance, and service life during OEM integration.

Inlet Protection and Fluid Path
Install a ≤30 μm inlet filter to prevent particles from entering the pump chamber. Keep tubing and fittings sealed to reduce leakage, pressure loss, or priming difficulty.

Mounting and Wiring
Use the four Ø3 mm bottom holes with 9.5 mm depth for mounting, and secure the pump with M4 self-tapping screws. Wiring definition: red wire is positive (+), and black wire is negative (–).

Material and Operating Conditions
The standard configuration uses a PA66 pump head, EPDM diaphragm, and PTFE valve. For corrosive liquids or special gases, confirm material compatibility before sample testing. Ambient temperature is 5°C to 40°C, and fluid temperature is 10°C to 60°C.

FAQ – BD-05TF3200WB Liquid Diaphragm Pump

Q1: When should I choose a 3.2 L/min diaphragm pump instead of a smaller liquid pump?

A 3.2 L/min pump is more suitable when the system requires faster liquid transfer, higher circulation capacity, or shorter filling and drainage times. The final selection should still consider the required working pressure and actual system resistance.

Q2: Can I select this pump based only on the maximum 10 bar pressure?

No. 10 bar is the maximum pressure capability, not the recommended continuous working pressure. For BD-05TF3200WB, the recommended working pressure is ≤2 bar. Pump selection should therefore be based on the actual operating point rather than maximum specifications alone.

Q3: Is BD-05TF3200WB suitable for liquids with different viscosities?

Liquid viscosity directly affects flow, suction performance, motor load, and temperature rise. For liquids significantly different from water, BODENFLO recommends providing the medium name, viscosity, temperature, required flow, and working pressure for evaluation before sample testing.

Q4: Can BODENFLO test the pump according to my actual system conditions?

Yes. Based on your tubing layout, suction height, working pressure, medium, flow requirement, and system resistance, BODENFLO can simulate relevant operating conditions and help determine a more suitable pump configuration and operating range before production.

Q5: Are there lower-flow diaphragm liquid pumps available?

Yes. For systems that do not require 3.2 L/min, BODENFLO also offers compact diaphragm liquid pumps such as:

These alternatives allow engineers to select a pump based on actual flow, pressure, medium, and equipment size rather than oversizing the pump.
