Mini Submersible Water Pump (Grow)

These small centrifugal pumps are perfect for incorporating into automatic plant watering systems like Grow. They could also come in handy for science experiments or for making tiny, smart water features!

The Picoblade-compatible connector means you can plug them easily into the bottom row of connectors on Grow HAT Mini. We also sell tubing that fits the outlet of these pumps nicely. 

If you're using them to water your plants you'll want to avoid soil getting sucked up into their workings, as this can jam the rotor. To get maximum longevity out of the motor, you should also avoid running the pump 'dry' for extended periods.

It just doesn't pump much..., depending on the tubing you use it will pump as high as 30cm, maybe 40, it is displayed as 55cm but with a tubing of 0.5cm ID, it's just really hard to make it work.

I now have 15 of these pumps accross two Pi Zeros in my Grow project they work well (I am feeding them with about 7 volts to get abit more head and they seem fine). Feeding them direcly from the Grow Hat they are abit limited and can only pump water up about a foot as the grow hat dosent seem to give them the full voltage.

these little pumps are ideal for the grow hat project and expanding your existing set-up which is what I have bought them for. My new setup will water all my tomato plants! Great product at a great price and delivered in double quick time.

Pumps didnt work and they I realised there was some bubbles in the pump; cleared them and wah-lah it started pumping that water to the plants :)

Great little pump good for small plants or water features it's also very quiet. Struggles a bit to get water over a 1m silicon tube. Could do with a 0.1" connector rather than 0.05".

It is not powerful enough to pump water through a full 1 metre tube if the tube is already filled with air although it fits perfectly with the silicone tubing.
