Water Pump, Submersible, 3-6V DC Submersible Water Pump AC Pump Submersible Pump 5v This 5V water pump is compact, inexpensive, and can run on voltages between 2.5 and 6 volts.

At only 220mA, it uses extremely little power and can handle up to 120 liters of water per hour. Simply immerse the motor’s output in water and attach the tube pipe. Maintain a water level above the DC Pump at all times. The motor might overheat and be damaged from a dry run, which would also make a lot of noise.

• Current consumption: 130220mA
• 2.5V 6V Operating Voltage
• Rate of Flow: 80-120 L/H
• Lifting Capacity Up to 40 x 110 mm
• DC Magnetic Drive System, Mode of Propulsion
• 500 hours of continuous use
• Engineering-grade plastic with an outlet 7.5 mm Outside Diameter | 5 mm Internal Outlet Diameter
• Submersible water pump using a low voltage motor

There are a wide variety of water pumps on the market, ranging in price from very cheap to very costly; but, when it comes to 5v submersible water pumps, there are only two real choices.
