The 3-6V Mini Submersible Water Pump is a compact, low-voltage solution for moving water in DIY electronics projects, aquarium setups, miniature fountains, cooling systems, and other small-scale applications. Its compact form factor makes it easy to install where space is limited, while its low operating current helps keep power requirements manageable.
Designed for simple integration, the pump operates from a 3.3–6V DC supply and can deliver a flow rate of approximately 80–120 L/H, depending on the operating conditions. Its submersible design allows the pump to be placed directly in water, making it convenient for compact water circulation and transfer applications.
The pump is particularly useful for students, hobbyists, makers, and electronics enthusiasts building Arduino-based or other microcontroller projects. It can be controlled through a suitable transistor or MOSFET driver when automated operation is required.
Whether you are building a small water fountain, aquarium circulation system, science project, hydroponic setup, or automated cooling project, this mini submersible water pump provides a practical and economical way to add water movement to your design.

A Water pump pushes water to the surface by converting rotary energy into kinetic energy into pressure energy. The water is drawn into the pump in two stages: first, in the intake, where the impeller rotates and pushes the water through the diffuser, and then in the discharge. It rises to the surface from there.
A Mini submersible water pump is lightweight, small in size, has low consumption, and makes little noise. A mini submersible water pump is used for building science projects, fresh water intake or exhaust systems for fish aquariums, and for garden watering systems.
The Mini Submersible Water Pump is a low-cost, small-size Submersible Pump Motor that can be operated from a 2.5 ~ 6V power supply. It can process up to 120 liters per hour while drawing only 220 milliamps. Simply plug the tube pipe into the motor outlet, submerge it in water, and turn it on.
Yes, designed with user convenience in mind, it's easy to use and maintain, perfect for DIY enthusiasts.
It has a flow rate of 80 - 120 L/H and a maximum lift of 40 - 110 mm, ensuring efficient water movement.

Excellent breakout board with added 5.1k resister for PD power trigger. Normal 4pin breakout board cannot draw power from PD but this one can.
Good quality & working as expected. Delivered on time.
It's good and excellent at its price range ad works correctly. But the thing confusing in this is that the pins markings I got confused which pin is shutdown and which pin is gpio... It's just written x and e . Soo it's kinda confusing but it a good product from what I have tested
It's works perfectly and I good overall in my opinion
It is Amazing and great item in this price
Veri usefull and cheap price from other shopping site, I use this module many project. Thank you robocraze
