A brushless diaphragm pump can help you maintain liquid pressure in compact equipment without relying on a bulky pumping system. However, selecting the right pump requires more than checking its maximum pressure or free-flow rate. You also need to consider the required flow under load, liquid compatibility, power supply, noise limits, and available installation space.
The JSG DC PUMP BD-07WB is a compact brushless DC diaphragm pump developed for clean-water pressurization and OEM liquid transfer. With a maximum outlet pressure of 10 bar and a maximum flow rate of 1 L/min, it supports equipment that needs controlled liquid delivery in a small footprint. Shenzhen Jingsuguang Technology Co., Ltd. has manufactured miniature pumps since 2003, helping OEM customers evaluate pump platforms and validate performance against actual operating conditions.
1. What Makes the BD-07WB Brushless Diaphragm Pump Suitable for OEM Equipment?
The BD-07WB combines a compact diaphragm structure with brushless DC drive technology. This configuration is suitable for equipment manufacturers who need pressurized liquid delivery and want to integrate a pump into a larger system.
Its main specifications include:
- Maximum outlet pressure: 10 bar
- Maximum flow rate: 1 L/min
- Working flow: At least 0.5 L/min at 5 bar
- Power supply: 12V DC, with a 24V option to be confirmed for the selected configuration
- Pump body: Polypropylene (PP)
- Standard diaphragm and valves: EPDM
- Inlet diameter: 6.5 mm
- Outlet diameter: 4.0 mm
These specifications provide a starting point for pump selection. Nevertheless, you should confirm the operating voltage, performance curve, dimensions, and connection details for your chosen configuration before finalizing your equipment design.
Why Choose a Brushless DC Diaphragm Pump?
Brushless drive technology eliminates the mechanical brushes used in conventional brushed motors. Depending on the motor and control design, this can reduce brush-related wear and support longer service intervals.
For OEM projects, the overall result still depends on operating pressure, duty cycle, heat dissipation, motor control, and the quality of the complete pump assembly. Therefore, evaluate the pump under your intended working conditions rather than relying on motor type alone.
2. Pressure and Flow: Select the Right Working Point
A pump’s maximum pressure and maximum flow are separate performance limits. They do not necessarily occur simultaneously, so you should verify the flow available at your required outlet pressure.
The BD-07WB provides a useful reference point: at 5 bar, its specified working flow is at least 0.5 L/min. Its maximum pressure is 10 bar, while its maximum flow is 1 L/min. Ask JSG DC PUMP for the relevant performance data if your equipment requires a specific flow-pressure combination.
Key Specifications Compared With Selection Requirements
| Parameter | BD-07WB specification | What you should verify |
|---|---|---|
| Maximum pressure | 10 bar | Required operating and transient pressure |
| Maximum flow | 1 L/min | Actual flow under system load |
| Flow at pressure | At least 0.5 L/min at 5 bar | Performance at your target working point |
| Power supply | 12V DC; 24V option requires confirmation | Available voltage and control method |
| Wetted materials | EPDM diaphragm and valves; PP body | Compatibility with the liquid |
| Connections | 6.5 mm inlet, 4.0 mm outlet | Tubing size and connection interfaces |
This comparison helps you identify technical gaps before ordering samples. If your application uses filters, narrow tubing, valves, or long fluid lines, include these components in your evaluation because they can affect the actual flow rate.
3. Liquid Compatibility and Application Scenarios
The BD-07WB is intended for liquid pressurization and transfer in compact OEM equipment. Its suitability for a particular application depends on the liquid, operating temperature, pressure requirements, and applicable safety standards.
Potential application areas include:
- Industrial automation: Compact liquid delivery and circulation modules.
- Laboratory equipment: Liquid handling systems requiring a defined pressure and flow.
- Water circulation equipment: Small-scale water transfer and pressurization.
- Commercial appliances: Integrated fluid delivery systems.
- OEM equipment: Custom machines with limited installation space and specific electrical interfaces.
Check Wetted Materials Before Ordering
The standard configuration uses EPDM for the diaphragm and valves, with a polypropylene pump body. FKM may be available as an alternative for confirmed compatible liquids.
However, neither EPDM nor FKM is universally compatible with every fluid. Before selecting materials, provide the liquid composition, concentration, temperature, and expected exposure time. For food-contact, medical, or other regulated applications, verify the required material documentation and product-level certifications rather than assuming compliance from the material name alone.
4. How to Specify a Brushless Diaphragm Pump for Your Project
A structured selection process helps reduce mismatches between the pump and your equipment.
- Define the working point. Specify the target flow at the required outlet pressure, rather than providing only maximum flow or pressure.
- Confirm the medium. Identify the liquid, temperature range, and material compatibility requirements.
- Set electrical requirements. Confirm 12V or 24V operation, available current, control signals, and duty cycle.
- Review mechanical integration. Provide installation dimensions, tubing sizes, mounting constraints, and noise targets.
- Validate a sample. Test the pump in your actual system under agreed operating conditions before pilot production.
- Approve production requirements. Confirm the model, interfaces, performance criteria, inspection requirements, and packaging specifications.
JSG DC PUMP supports OEM and ODM projects through pump selection, configuration review, sample validation, and controlled production. Its ISO 9001:2015-certified quality-management system provides a framework for quality control, while project-specific acceptance criteria should be agreed before production begins.
5. Frequently Asked Questions
What is the maximum pressure of the BD-07WB pump?
The BD-07WB has a maximum outlet pressure of 10 bar. Its specified working flow is at least 0.5 L/min at 5 bar. Confirm the required flow-pressure performance for your application before selecting the pump.
Can this brushless diaphragm pump operate at 24V DC?
A 24V DC option is listed for the product, but the detailed specification table identifies 12V DC. Confirm the available voltage configuration, motor control, and electrical parameters with JSG DC PUMP before ordering.
Is the BD-07WB suitable for medical or food-processing equipment?
It may be considered for suitable equipment after technical evaluation, but application suitability cannot be assumed. Verify liquid compatibility, wetted-material documentation, applicable regulatory requirements, and any necessary product certifications before use.
