Versatile Water & Air Pump
Unlike pumps designed exclusively for liquids, the R385 diaphragm pump can be used for both water and air applications, making it a useful component for electronics enthusiasts, makers, students and DIY projects.
Its DC operation also makes it easy to incorporate into battery-powered or electronically controlled systems using suitable relays, MOSFET modules, timers or microcontrollers.
Typical Applications
The R385 DC pump can be used for:
- Aquarium and fish tank projects
- Small water circulation systems
- DIY water pumping projects
- Automatic watering systems
- Small fountains and water features
- Water transfer devices
- Air pumping applications
- Electronics and Arduino projects
- Educational and prototype projects
- Custom automated pumping systems
Compact Design
The small form factor of the R385 6–12V diaphragm pump makes it particularly useful where space is limited. The approximately 6mm internal / 9mm external outlet connection allows suitable tubing to be connected for custom installations.
