Which Media and Materials Is This micro diaphragm liquid pump Compatible With?
The BD-07WB is mainly suitable for clean water and compatible mild liquids.If the liquid contains chemicals, solvents, oil, fragrance, disinfectant, or high-temperature fluid, you must check for material compatibility before making a selection.
Standard EPDM
| Media Type | Notes |
| Water | Standard application |
| Inert liquid | Final compatibility should be confirmed by project |
| Mild liquid | Cost-effective and suitable for Non-corrosive, chemically inert liquid |
Enhanced FKM
| Media Type | Notes |
| Inert liquid | Recommended when better chemical resistance is needed |
| Corrosive liquid | Better chemical resistance and higher temperature resistance |
What Applications Is This micro diaphragm liquid pump Suitable For?
- Water Purifier and RO System
The BD-07WB can be used in compact water purification and RO booster systems. These applications usually require stable pressure, reliable sealing, and consistent water output. For this type of system, customers should focus on working pressure, tube connection, inlet filtration, and long-term leakage control.
- Beverage Machine and Liquid Dispensing Equipment
For beverage machines, coffee equipment, and small liquid dispensers, the BD-07WB can provide stable water delivery in a compact structure. Customers can choose suitable tubing and materials according to the liquid type, working temperature, and hygiene requirements.
- Cleaning and Spray Equipment
This pump is ideal for small cleaning machines, spray systems, and atomization equipment that require pressurized water.For these applications, pressure stability, nozzle matching, and anti-blocking design are important.
- Laboratory and Instrument Liquid Transfer
The BD-07WB provides compact liquid transfer with controlled flow and reliable performance for small instruments and laboratory devices. Material compatibility should be confirmed if the liquid is not clean water.
How Do I Choose the Right Version of This Pump?
- If You Need Higher Pressure
Choose the BD-07WB high-pressure version. It is more suitable for RO systems, spray devices, and pressurized water circuits.
- If You Need Lower Noise
Use rubber mounting pads, flexible tubing, and suitable system layout to reduce resonance. If noise is a key requirement, sample testing under real working conditions is recommended.
- If You Need Longer Life
Confirm the working pressure, duty cycle, and liquid condition before selection. Long-time operation under excessive pressure may increase current, temperature, and wear.
- If the Liquid Is Not Clean Water
Confirm the wetted materials before testing. For chemical liquid, fragrance, disinfectant, or oil-based liquid, FKM or other special material options may be needed.
- If Space Is Limited
Provide the internal layout, tube direction, and mounting requirements. We can help check whether the BD-07WB can fit the available space or whether a customized connector is needed.
Real Project Cases Using This DC Diaphragm Water Pump
- RO Water Purifier System
A customer needed a compact pump for a household water purifier system. The system required stable pressure and reliable liquid transfer within a limited internal space. We recommended a 24V high-pressure DC diaphragm water pump based on the required working pressure of 5.5 bar and flow range of 0.8 L/min. After testing with the customer’s filter and tubing system, the pump achieved a stable output of 5.8 bar and met the customer’s pressure requirement.
- Beverage Dispensing Machine
A beverage equipment customer required a small pump for water transfer inside a compact machine. The main concerns were stable water delivery at 1 L/min, easy tube connection, and reliable intermittent operation. We recommended our BD-08WB 12V diaphragm pump. To improve installation efficiency, we adjusted the connector direction and recommended suitable 6.5mm ID silicone tubing. The final solution helped the customer simplify the internal liquid path and improve system reliability.
