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

For most OEM applications, the standard material configuration provides a practical balance of compatibility, durability, and stable performance.

Component Material / Feature
Pump Head PPS
Diaphragm EPDM
Valve EPDM

If your application involves more aggressive media or stricter durability requirements, upgraded material options can be considered. Optional configurations such as a PTFE diaphragm and FFKM valves are available for applications involving corrosive gases, chemical reagents, or enhanced chemical resistance requirements.

OEM Customization Options

If your system requires specific electrical configurations, material compatibility, or installation interfaces, selected items can be customized to better match your application.

Item Customization Options

FAQ – BD-05TF650WBD Diaphragm Water Pump

Q1: Why is the pressure of my diaphragm water pump lower than expected?

Lower pressure is usually caused by leakage, air trapped in the fluid path, clogged filters, or excessive backflow. Although the BD-05TF650WBD diaphragm water pump can deliver up to 5 bar maximum pressure, BODENFLO recommends operating within 3 bar for continuous use to achieve better reliability and longer service life.

Q2: Can this liquid vacuum pump transfer both liquid and gas?

Yes. The BD-05TF650WBD liquid vacuum pump features a gas-liquid compatible diaphragm design. In addition to transferring liquids, it provides 0.8 L/min gas flow, 45 kPa positive pressure, and -28 kPa vacuum for compact OEM pneumatic applications.

Q3: Does this diaphragm water pump support PWM speed control?

Yes. The BD-05TF650WBD diaphragm water pump supports 0–5 V PWM speed control, allowing engineers to adjust pump speed and liquid flow according to different operating conditions and system requirements.

Q4: What is the lead time for BD-05TF650WBD diaphragm liquid pumps?

Sample lead time is typically 3–5 days. For bulk orders, production lead time is usually 20–30 days, depending on order quantity and customization requirements.

Q5: Which liquid pump should I choose for higher pressure or higher flow?

If your application requires higher liquid pressure, the BD-05TF400WB is the recommended choice, providing up to 6 bar water pressure. If your system requires higher liquid flow instead, BODENFLO also offers the BD-05TF800WBD, which delivers up to 800 mL/min water flow for high-flow liquid transfer applications.
