Micro Vacuum Pump Air Pump Motor - 12V DC

Specifications

• Motor Type: Brushed DC 370

• Operating Voltage: 9V - 13.5V DC

• Nominal Voltage: 12V DC

• Current Draw: ~200mA - 300mA

• Air Flow: 2.0 - 3.0 Litres/Min

• Max Vacuum (Suction): > -50kPa

• Max Pressure (Outlet): > 80kPa

• Nozzle Diameter: 4.2mm OD (Fits 3mm ID Tubing)

• Noise Level: < 60dB

• Life Cycle: ~500 Hours (Intermittent)

Key Applications & Projects

• Home Automation: Automated plant watering systems (using air pressure to push water).

• Appliance Repair: Replacement pump for coffee machines and automatic soap dispensers.

• Robotics: Vacuum suction grippers running off a 3S LiPo or 12V rail.

• Lab Equipment: Small-scale gas sampling or filtration.

Virtual Technician & Wiring

• ⚠️ Driver Choice: Since this runs at 12V, you cannot power it directly from an Arduino (5V). You must use a Motor Driver (L293D/L298N) or a Relay Module with an external 12V source.

• Polarity:

  • Red Dot: Positive (+) 12V

  • No Dot: Negative (-) GND

• Tubing: Use 3mm ID Silicone Tubing.

Accessories & Parts

What's Included:

• 1 x Micro Vacuum Pump Motor (12V - 370 Type)

Required Alternatives:

• Tubing: 3mm ID Silicone Hose.

• Power: 12V 1A Adapter or 3S LiPo Battery.

• Control: 12V Relay or MOSFET Module.

Frequently Asked Questions (FAQ)

1. Is this the same size as the 3.7V pump? Yes, physically they are identical (Type 370 motor). Only the internal copper winding is different to handle 12V.

2. Can I run this on 5V? It might spin slowly, but suction will be very weak. It is designed for 12V.

3. What tubing fits? 3mm Inner Diameter (ID) silicone tubing.

4. Can I use a 12V 2A adapter? Yes, absolutely. The pump will only draw the current it needs (~300mA), so a 2A adapter is safe.

5. Is it waterproof? No. Do not submerge.

6. Can I pump water with it? Not recommended. It is designed for air. Pumping water can rust the motor.

7. How loud is it? Moderate buzzing sound (~60dB).

8. Can I use it for a vacuum sealer? For small bags, yes. For large kitchen bags, use the larger 555 pump.

9. Does it get hot? 12V motors can get warm. Avoid running continuously for >15 minutes without cooling.

10. Is the inlet marked? Side nozzle is typically Inlet (Suction), Center nozzle is Outlet (Blowing).

11. Can I use PWM? Yes, speed control via PWM works well on 12V.

12. Will it work with a 9V battery? Yes, but it will run slightly slower than at 12V.

13. What is the max pressure? ~80-100 kPa.

14. Is it oil-free? Yes.

15. Can I use this to aerate a fish tank? Yes, if you have a 12V power source (like a backup battery).

16. Is it better than the 555 pump? It is smaller and uses less power. The 555 pump is stronger (15L/min vs 3L/min). Choose based on your need for flow vs compactness.

17. Can I reverse the flow? No, reversing polarity only spins the motor backward; it does not reverse the check valves.

18. Does it need a diode? If using a relay/MOSFET, always use a Flyback Diode across the motor terminals to protect your electronics from voltage spikes.

19. What is the nozzle material? Plastic (Nylon/ABS). Handle with care.

20. Can I use it for cupping therapy? Yes, it generates sufficient suction for small cupping applications.
