Mini Submersible Water Pump


SKU: OTH-033


This miniature pump is designed to be submerged in water and run with low voltage DC power. The pump can flow between 80 and 120 liters per hour and lift the water a maximum of 110cm / 43”. Input voltage can range between 2.5 and 6V – but to achieve the maximum lift / flow rates 6V will be required. Ideal for watering small planters!

To operate the pump, simply apply 2.5 – 6VDC to the red wire, and ground to the black wire. Controlling the motor with a microcontroller can be done by following our tutorial: Controlling A DC Motor With Arduino
