Product Overview
The BD-07W is a compact brushed DC diaphragm water pump designed for OEM liquid transfer systems requiring stable pressure, reliable water flow, and straightforward integration.
Depending on the selected voltage and hydraulic configuration, the pump can deliver a maximum flow of up to 1 L/min and a maximum pressure of up to 10 bar. This makes it suitable for water purification equipment, beverage machines, cleaning devices, spraying systems, laboratory instruments, and other compact liquid delivery applications.
Its brushed DC motor provides a cost-effective, mature drive solution with simple on/off control and fast response. It suits OEM equipment operating within the specified pressure, temperature, and duty-cycle limits.
Core Selling Points of This DC Diaphragm Water Pump
1.Our mature brushed motor design provides a cost-effective drive solution, offering an ideal balance of performance with simple control and fast response.
2.The pump’s self-priming diaphragm structure enables it to draw liquid from a lower-positioned tank, even without pre-filling the pump chamber.
3.The pump’s oil-free design prevents liquid contamination, making it ideal for high-purity and precision applications.
4.Combining high pressure with a compact footprint, this pump simplifies integration into space-constrained OEM systems.
5.Highly customizable with 12V/24V models, standard or PWM control, and tailored electricals for OEM systems.

Which Media and Materials Is This DC Diaphragm Water Pump Compatible With?
The standard BD-07W liquid path uses a POM pump head with EPDM diaphragm and valves. Always test material compatibility under your specific conditions, including liquid, concentration, temperature, pressure, and operating time.
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 DC Diaphragm Water Pump Suitable For?
1.Cleaning and Disinfection Equipment
The BD-07W can provide pressurized liquid for portable cleaning devices, surface-cleaning systems, and selected disinfection equipment. Liquid concentration and material compatibility must be confirmed.
2.Spraying and Misting Systems
The pressure capability makes the pump suitable for compact spraying, humidification, cooling, and mist-generation systems. Nozzle resistance and required flow at pressure should be tested as a complete system.
3.Laboratory and Analytical Equipment
You can integrate the pump into laboratory water supply, washing modules, sample-preparation equipment, and instrument-cleaning systems. PWM voltage control can be evaluated when several flow or pressure levels are required.
4.OEM Liquid Transfer Equipment
The BD-07W suits customized equipment needing a compact 12V or 24V liquid pump. It offers self-priming capability, high pressure, and cost-effective brushed motor operation.
How Do I Choose the Right Version of the BD-07W Pump?
1.Choose the Brushed Version for Cost-Effective Integration
Choose the brushed BD-07W when cost, simple control, and straightforward integration are priorities. For unusually long continuous duty or very high cycle counts, confirm motor life at the actual working point.
2.Choose PWM Control for Adjustable Flow
PWM voltage control can be evaluated when the equipment requires several operating levels. The final controllable range depends on duty cycle, pressure, supply voltage, driver design, and system resistance.
3.Choose Materials According to the Liquid
Use the standard POM and EPDM version for clean water and compatible mild liquids. For special chemicals, provide the liquid name, concentration, temperature, and SDS for compatibility evaluation.
4.Select Based on the Real Working Point
Select the pump configuration based on the required flow at your working pressure, not on free-flow or maximum-pressure data alone.
Real Project Cases Using This DC Diaphragm Water Pump
1.Compact RO Water Purification System
A customer developing a compact countertop RO water purifier required a 12V pump capable of delivering approximately 0.6 L/min at 5 bar through the membrane and filter system. We recommended the BD-07W brushed DC water pump. It offers a 1 L/min max flow, around 0.6 L/min at 6 bar, and 10 bar max pressure.During testing, the pump maintained a stable pressure of 5.5–5.6 bar and a flow rate of approximately 0.6–0.65 L/min. This met the customer’s performance and space requirements.
2.Portable High-Pressure Cleaning Device
A manufacturer of portable cleaning equipment needed a compact 24V water pump to supply four spray nozzles with a total target flow of 0.45 L/min at 4 bar.We supplied the 24V BD-07W brushed DC water pump. It offers a maximum flow of 1.0 L/min, and about 0.5 L/min at 4 bar.During testing, the pump maintained an operating pressure of 3.8–4.1 bar, while each nozzle delivered approximately 0.10–0.12 L/min.This provided a stable and consistent spray pattern.
