If you need reliable fluid transfer in compact equipment, choosing the wrong micro diaphragm pump can lead to insufficient flow, excessive noise, poor material compatibility, or integration problems. You need a pump that matches your operating pressure, required flow rate, voltage, installation space, and working medium—not just one that fits your equipment physically.
The JSG-03 series from Shenzhen Jingsuguang Technology Co., Ltd. offers a compact pumping solution for selected liquid-transfer and vacuum applications. With 6V, 12V, and 24V DC options, a stated water flow rate of 400–700 mL/min, and a maximum vacuum specification of -30 kPa, this series supports a range of OEM equipment designs. Understanding its specifications and operating conditions will help you determine whether it suits your application.

Key Benefits of a Small Diaphragm Pump
Compact Design for Equipment Integration
Measuring approximately 64 × 30 × 32 mm, the JSG-03 can fit into equipment with restricted internal space. Its compact dimensions and low weight are useful when designing portable instruments, embedded fluid systems, and space-conscious assemblies.
Flexible Voltage and Material Options
The available 6V, 12V, and 24V DC configurations provide flexibility for different power systems. Meanwhile, EPDM and FKM diaphragm options allow you to evaluate material compatibility with the intended liquid or operating environment.
- EPDM: Consider for compatible water-based media and applications requiring suitable elastomer flexibility.
- FKM: Consider for compatible media that require different chemical and temperature resistance characteristics.
Neither material is universally compatible with every liquid. Confirm the specific formulation, concentration, temperature, and wetted components before selecting a configuration.
Low-Noise Operation and Service Life
The stated noise level is approximately 50 dB under the manufacturer’s specified test conditions. This may be relevant to laboratory instruments, household appliances, and other equipment where operating noise matters.
The published service-life figures are up to 5,000 hours for one motor version and 1,000 hours for the other. Actual service life depends on operating conditions, duty cycle, voltage, medium, and maintenance requirements.
Micro Diaphragm Pump vs. Other Pump Types
Different pump designs address different engineering requirements. Use the following comparison as an initial screening guide rather than a substitute for performance testing.
| Pump Type | Typical Strength | Considerations |
|---|---|---|
| Micro diaphragm pump | Compact fluid handling and vacuum generation | Verify flow under load and diaphragm compatibility |
| Miniature piston pump | Pressure or vacuum generation for selected gas applications | Evaluate vibration, noise, and duty cycle |
| Micro liquid pump | Liquid transfer and circulation | Check wetted materials and liquid properties |
| Miniature air pump | Air supply and inflation | Confirm pressure, flow, and pneumatic connections |
The JSG-03 is worth evaluating when your equipment requires compact liquid transfer alongside a specified vacuum capability. If your primary requirement is high-pressure gas delivery or continuous high-volume liquid circulation, compare alternative pump platforms before choosing a model.
Applications of the JSG-03 Micro Diaphragm Pump
A micro diaphragm pump can support different functions depending on its configuration and the surrounding system.
- Water purification and filtration: Supports water movement in compact filtration equipment when flow and material compatibility meet requirements.
- Misting and humidification: Supplies liquid to suitable misting systems after checking nozzle resistance and required pressure.
- Medical and laboratory equipment: May support selected fluid-handling or vacuum functions, subject to device-specific validation and applicable regulatory requirements.
- Inkjet printing: Can support compatible ink transfer when viscosity, chemical compatibility, and flow stability are verified.
- Agricultural spraying: May suit compact spraying systems after evaluating chemical resistance, pressure requirements, and operating conditions.
- Vacuum handling and packaging: Can provide suction for suitable lightweight handling or packaging applications when the required vacuum and evacuation time are achievable.
Application suitability must be confirmed for the complete system. A pump’s technical specifications alone do not establish medical-device approval or suitability for every chemical.
How to Select the Right Micro Diaphragm Pump
Follow these steps before requesting a sample or placing an OEM order.
- Define the working point. Specify the required flow rate at the actual pressure or vacuum, rather than relying only on maximum flow.
- Confirm the medium. Identify the liquid or gas, its viscosity, chemical composition, and operating temperature.
- Check electrical requirements. Confirm the supply voltage, current limit, duty cycle, and any motor-control requirements.
- Review installation constraints. Provide available space, tubing dimensions, connectors, noise limits, and mounting details.
- Validate a sample. Test the selected configuration under representative loads and agree on acceptance criteria before pilot production.
This process helps reduce mismatches between laboratory specifications and real operating performance.
