NEW PRODUCTS – Submersible 3V DC Water Pumps – Vertical + Horizontal Types


First up, the Horizontal Type!

4546 quarter ORIG 2020 02

Make fountains or plant-watering projects with this submersible water pump. It’s great for beginner projects and super easy to use! The pump is basically a DC motor that is powered with 3V and draws 100mA. When powered, the pump sucks water in from the side of the plastic casing and pushes it out the tubing port. The pump must be primed by keeping it inside water at all times. Reversing the polarity does not turn it into a suction device, it will only pump water!

This isn’t for use with drinking water! We don’t have longevity rating for this pump, we’ve run it for a week and it seems OK but we would not recommend it for long term installations. It’s best used by students and artists who want something simple and inexpensive.

You can PWM the motor to speed up or slow down the flow rate. Works great with either a power transistor (basic on/off) or a motor driver chip such as the L293D. If you need a self-priming / food-safe / reversible direction pump, check out our peristaltic pumps!

Please note: This is just the pump and power wires. Silicone tube is not included, so why not grab this 1 meter long PVC tubing while you’re here?

Next up, the Vertical Type!

Happy New Year 2025
Happy New Year from Adafruit!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
