Water Pump 6V - 12V with 1m silicone tube

6 - 12V R385 diaphragm pump with 1M of silicon hose for use in projects that require the pumping of liquids or air, such as; small aquariums or water features.

Availability: In Stock.

2567 £9.99
(£11.988 incl VAT)

This R385 diaphragm pump is the perfect choice for any project that requires water to be moved from one place to another. The pump is supplied with 1M of silicon hose that you can cut to your requirements, the hose provides a good seal and will not leak.

Possible uses/projects include; a small aquarium pump, automatic plant watering system, making a water feature or music activated dancing water features to name but a few. When pumping a liquid the pump runs very quietly. The pump is also capable of pumping air, though when pumping air the pump is quite noisy in comparison.

The pump requires between 6 - 12V DC and between 0.5 - 0.7A and will deliver its maximum operating values when power is at the upper end of these ranges.

The pump can handle pumping heated liquids up to a temperature of 80 degrees Celcius and when suitably powered can suck water through the tube from up to 2m and pump water verticaly for up to 3m.


  • The +ve connector on the pump is indicated with a red mark.


  • Maximum suck range of 2m.
  • Maximum head range of 3m.
  • Works with liquids of up to 80 degrees celcius.
  • Maximum flow rate of up to 1 - 3L/min.

    A: Hi Steve, I have heard back from the supplier and unfortunately they can’t confirm that it would be safe to be used with drinking water. As such you would need to use a pump which states it is safe to use with drinking water. Sorry we couldn’t help on this occasion.

    A: Hi Jamie, You could go really basic with the circuit and use the temperature sensor on the micro:bit to determine when and for how long the pump should run for. However if you want to be a little more accurate in when to turn it on and off you could use a moisture sensor, connect this up to the micro:bit and then use this to send the signal and then code the micro:bit so that as the resistance of the moisture sensor changes it determines how wet the soil is. Unfortunately we don’t currently have a moisture sensor, but there are a few different one’s out there that should work fine. Just take care that if you use one power supply to power both the moisture sensor and the micro:bit that you don’t exceed 3V’s into the micro:bit.
