DC 12V Mini Vacuum Pump 5L/min 120kPa Negative Pressure Pump

DC 12V Mini Vacuum Pump – Compact, Quiet & Reliable Negative Pressure Suction Pump

Looking for a dependable mini vacuum pump that delivers strong suction performance in a compact package? This DC 12V Negative Pressure Vacuum Pump is engineered for precision and efficiency, offering up to 5L/min flow rate and a maximum pressure of 120kPa. Whether you need it for medical equipment, gas analysis, laboratory sampling, or industrial instrumentation, this pump gets the job done reliably and quietly.

Powered by a miniature DC motor, it drives an internal eccentric mechanism that causes a diaphragm to reciprocate — creating consistent, oil-free, maintenance-free suction. With low noise output (under 60dB) and minimal power consumption, it's ideal for environments where quiet and clean operation are critical.

Made in Mainland China.

Frequently Asked Questions

Q: What is this DC 12V mini vacuum pump used for?

A: This mini vacuum pump is designed for applications requiring negative pressure suction, including medical equipment, gas analysis and sampling, laboratory instrumentation, metering devices, and other industrial or scientific uses. Its compact size and oil-free design make it especially suitable for sensitive environments.

Q: Does this vacuum pump require maintenance or oil?

A: No — this pump is completely oil-free and maintenance-free. The diaphragm design ensures it delivers clean, uncontaminated airflow without the need for lubrication or regular servicing, making it ideal for both lab and field use.

Q: What power supply does this vacuum pump need?

A: This pump operates on DC 12V with a rated current of 500mA and a power draw of just 6W. It can be powered by any compatible 12V DC power supply. It is not designed for AC mains power directly — a 12V adapter or power supply is required.

Q: How quiet is this mini vacuum pump during operation?

A: The noise level is rated at less than 60dB, making it one of the quieter options for small-scale vacuum applications. It's well-suited for medical, laboratory, and office environments where noise is a concern.

Q: Does the pump come with a mounting bracket or holder?

A: Yes! The package includes a mounting holder so you can securely fix the pump in place during operation. This helps reduce vibration and noise during use.
