3V–24V Mini Diaphragm Air Pump
370-XB
Small air pumps
Small Size, Useful Pressure
The pump weighs only about 60 g but can reach ≥100 kPa pressure.
This makes the small diaphragm air pump suitable for products that need enough pressure without using a larger pump.
A smaller pump also leaves more room for valves, tubing, circuit boards and other parts inside the equipment.

What Makes This Pump Different?
- Fast pressure build-up: 500 cc chamber reaches 300 mmHg in under 10 seconds.
- Made for repeated cycling: Tested at 10 s ON / 5 s OFF for over 30,000 cycles.
- Low pressure loss: Leakage is below 3.0 mmHg/min at 300 mmHg.
These features make it well suited to small pneumatic systems that need quick, repeated pressurization.

Where Can It Be Used?
Essential Oil Equipment
The pump can provide airflow or pressure for compact essential oil machines.
Its small size suits devices where the air path and electronic parts share limited internal space.
Adult Wellness Devices
It can be integrated into products that use repeated inflation, pressure holding and release.
The short operating cycle fits devices that require controlled pneumatic movement.
Compact Home Appliances
The pump can serve as a built-in air source for small household products with pneumatic functions.
It is suitable where low-voltage operation and a compact air circuit are required.
Pressure Boosting Modules
The pump can be used in small pressure-boosting systems that need short bursts of compressed air.
It is better suited to intermittent pressure build-up than continuous high-flow operation.

Technical FAQ: DC Micro Diaphragm Pumps
Micro Diaphragm Pump Technical FAQ
1. What is the maximum self-priming height of this DC micro diaphragm pump? The maximum self-priming height is up to 2 meters (6.5 feet). This is achieved through a high-efficiency valve design and airtight diaphragm seals, making it ideal for coffee machines and medical devices where the water reservoir is located below the pump level.
2. How can I adjust the flow rate of a 12V/24V micro water pump? You can precisely control the flow rate by adjusting the input voltage or using PWM (Pulse Width Modulation) speed regulation. Reducing the voltage lowers the motor speed, allowing for fine-tuned dosing in precision medical or laboratory applications.
3. Can the Pincheng micro diaphragm pump run dry without damage? Yes, our diaphragm pumps can run dry for extended periods. Unlike centrifugal pumps, the diaphragm design does not rely on the pumped medium for cooling or lubrication of the critical seals, ensuring high reliability in intermittent air and liquid transfer.
4. What is the noise level of this micro pump during operation? The noise level is strictly controlled below 45dB at a 30cm distance. By utilizing internal acoustic damping and a balanced eccentric motor design, our pumps are suitable for “whisper-quiet” environments like hospital wards and high-end offices.
5. Are the pump materials safe for food-grade or corrosive gas sampling? Yes, we offer multiple material options including FDA-compliant EPDM for food/beverage use and PTFE (Teflon) for corrosive gas sampling. All fluid-contact components are certified to meet RoHS and REACH environmental standards for global compliance.
