Mini Diaphragm Vacuum Pump – 12V/24V DC, Small & Oil-Free

Whether you need a reliable mini vacuum pump for laboratory work, a compact 12V vacuum pump for field sampling, or a quiet 24V vacuum pump for medical equipment, this small diaphragm pump delivers consistent negative pressure in a lightweight, oil-free design built for professionals and engineers alike.

Dual Voltage: 12V & 24V DC Compatible This small vacuum pump operates on both 12V and 24V DC input, making it one of the most flexible mini diaphragm vacuum pumps available. Whether you're running it from a vehicle battery, a benchtop power supply, or a battery-powered field kit, it adapts without compromise.

Quiet, Oil-Free Operation Unlike piston-type models, this micro vacuum pump uses a precision diaphragm mechanism that runs quietly and requires no oil — eliminating contamination risk and reducing maintenance to almost nothing. Ideal for cleanroom environments, medical devices, and sensitive lab applications where noise and cleanliness matter.

High Vacuum Performance in a Compact Body Don't let the size fool you. This miniature vacuum pump delivers suction up to -85 kPa, stable airflow, and reliable continuous-duty performance — all in a body weighing under 500g. It fits tight instrument enclosures, mobile carts, and compact workstation builds where space is limited.

Brushed & Brushless Motor Options Available with either a brushed DC motor for cost-effective everyday use, or a brushless vacuum pump motor for extended service life and lower electromagnetic interference — suitable for precision instruments and longer duty cycles.

This small diaphragm vacuum pump is purpose-built for demanding use cases across industries:

• Laboratory & Research — vacuum filtration, degassing, and gas circulation in analytical instruments
• Medical & Healthcare — wound therapy devices, negative pressure monitoring, and portable diagnostic equipment
• Gas Sampling — field air quality sampling, environmental monitoring, and portable gas analyzers
• Industrial Automation — pick-and-place suction, vacuum holding fixtures, and inline process control
• Electronics & DIY — PCB handling, reflow soldering assist, and custom vacuum systems

For engineers sourcing a compact vacuum pump that balances portability, cleanliness, and performance, this model checks every box. It's quieter than piston pumps, cleaner than oil-lubricated models, and more durable than low-cost alternatives. With 12V and 24V compatibility, it integrates directly into mobile systems, lab benches, or OEM equipment without additional voltage conversion.
