The 12V Mini Submersible Water Pump is a compact and practical solution for moving and circulating water in DIY, educational, automation and small-scale water systems. Operating from a 12V DC supply, this fully submersible pump can deliver a maximum flow rate of 10 L/min (600 L/h), making it suitable for applications where reliable water circulation is required in a compact form factor.
Unlike a standalone DC motor, this product is designed specifically as a water pump, with the motor and pumping mechanism integrated into the unit. Simply place the pump in the water source and connect it to a suitable 12V supply to circulate water through your system.
It can be used for aquariums, hydroponic systems, automatic irrigation, fountains, water circulation, cooling systems and Arduino-based automation projects. Its 12V operation also makes it convenient for battery-powered and solar-powered DIY systems when the electrical requirements are properly matched.
Flow Rate and Pump Performance:
The pump has a maximum flow rate of 10 L/min, equivalent to approximately 600 L/h. The actual flow delivered by the pump depends on the pumping height, tubing length, outlet restrictions and other resistance in the water system.
For applications requiring a specific water delivery rate, consider both the flow rate and maximum head height rather than selecting a pump based on flow rate alone.
Features:
- 12V DC Operation: Designed to operate from a 12V DC power source.
- 10 L/min Maximum Flow: Provides water circulation at up to approximately 600 L/h under suitable operating conditions.
- 8W Power Consumption: Suitable for compact water circulation and DIY applications.
- Fully Submersible: Designed to operate while immersed in water.
- Compact Water Pump: Easy to integrate into small tanks, reservoirs and experimental setups.
- Multiple Applications: Suitable for aquariums, hydroponics, irrigation, fountains and water-circulation projects.
- Arduino Compatible Projects: Can be integrated with Arduino-based automation using an appropriate relay or MOSFET driver.
- DIY-Friendly: Useful for students, makers, hobbyists and prototype development.
Applications:
Hydroponics
Use the 12V submersible water pump for hydroponics to circulate nutrient solution between a reservoir and growing system. It can be incorporated into small-scale hydroponic prototypes and educational projects where controlled water circulation is required.
Aquarium Water Circulation
The compact 12V water pump can be used for aquarium water circulation, small water features and DIY filtration setups, provided the pump's flow and operating specifications match the aquarium system.
Automatic Irrigation with Arduino
Build an Arduino automatic irrigation system by connecting the pump to a suitable relay module or MOSFET driver. A soil-moisture sensor can be used to detect dry soil, allowing the Arduino to activate the pump and deliver water automatically.
DIY Water Features
Create small fountains, water displays and educational water-flow experiments using the compact submersible design.
Water Circulation Projects
The pump can be integrated into DIY water-cooling, reservoir circulation and other maker projects requiring controlled movement of water.
Arduino Automatic Irrigation Project
The pump can be used as the water-delivery component in an Arduino-based automatic irrigation system.
A typical setup can include:
Soil Moisture Sensor → Arduino → Relay/MOSFET Driver → 12V Water Pump
When the soil moisture level falls below the programmed threshold, the Arduino can activate the driver circuit and switch on the pump. Once sufficient moisture is detected, the controller can switch the pump off.
Note: Do not power the pump directly from an Arduino GPIO pin. Use an appropriately rated relay module or MOSFET driver and a separate 12V power supply capable of handling the pump's current requirement.
