How does it work:

The JT-DC3W Mini Mute Submersible Pump operates by utilizing a brush motor powered by a DC3V or 4.5V power source. When power is supplied, the motor generates rotational motion, which is transferred to the impeller. This impeller creates a low-pressure zone around itself, drawing water into the pump through an intake port. As the impeller continues to spin, it propels the water out of the pump through an outlet port with force. The pump's ability to lift water vertically, known as the head, is adjustable based on the voltage supplied. At 3V, the pump has a head of 0.35 meters, while at 4.5V, it increases to 0.5 meters.

Designed to be submerged in water during operation, the pump effectively circulates water without risking damage to internal components. Additionally, it is engineered for low noise operation, emitting a maximum noise level of 40dB, making it suitable for noise-sensitive environments.
