- Pump DC 12V R385 Micro Diaphragm Water Pump YX DC12V 385 14150
- Pump
Features
- Self-priming design for drawing water from a lower reservoir.
- Diaphragm mechanism separates the liquid path from the motor mechanism.
- Rubber mounting brackets help reduce vibration and operating noise.
- Compact size for small water transfer and circulation systems.
- Suitable for DIY, educational, and liquid dispensing projects.
Principle of Operation

The 385 DC motor drives a diaphragm that changes the volume of the pump chamber. This creates suction at the inlet and pressure at the outlet, allowing the pump to draw in and discharge liquid.
Applications
- Small water transfer systems
- Liquid dispensing and circulation
- DIY automation projects
- Educational and hobby projects
Wiring

Connect the pump terminals to a suitable DC power supply within the rated voltage range of 6–12V. For 12V operation, use a power supply capable of providing sufficient current. Do not connect the pump directly to a microcontroller GPIO pin. Use a suitable motor driver or switching circuit if controlling it with an Arduino, ESP32, or another controller.
