Frequently Asked Questions

Q: What is the difference between the JD-C1 and JD-C2 miniature DC vacuum pump models?

A: The JD-C1 model offers a higher airflow rate of 15 L/min and is available in both brushed and brushless motor variants at 12V and 24V. The JD-C2 model provides a slightly lower flow rate of 12 L/min and is available in brushed motor versions only at 12V and 24V. Choose JD-C1 for higher throughput or brushless longevity, and JD-C2 for lighter-duty applications.

Q: What is the advantage of choosing a brushless motor DC vacuum pump?

A: Brushless motor pumps have no contact brushes that wear out over time, resulting in a significantly longer operational lifespan, lower operating noise, and reduced heat generation compared to brushed motors. They are ideal for continuous-run or mission-critical applications where reliability and minimal maintenance are priorities.

Q: Can this pump handle both pushing air and creating suction (vacuum)?

A: Yes. This miniature DC pump is designed for dual-mode operation — it can function as a positive pressure pump (pushing/blowing air) or a negative pressure pump (drawing air/creating vacuum suction), making it highly versatile across a wide range of projects and systems.

Q: Is this pump suitable for liquids or only air/gas?

A: This pump is primarily designed for air and gas handling. It is not rated for direct liquid pumping. For fluid transfer applications, please ensure any liquid contact is managed through appropriate secondary equipment such as a diaphragm or peristaltic pump stage.
