Waterproof Design: The water cooling pump features a waterproof construction, allowing it to operate effectively even when submerged. It is built for durability and long service life. Extended Operation: Equipped with a JR plug compatible with receivers, the pump can run continuously for up to 15 hours at 5V without interruption, ensuring reliable performance. Efficient Performance: During extended use, the pump may generate heat, but this remains within normal operating limits and does not affect functionality. Low Noise Operation: Designed for quiet performance, the pump provides a smooth and quiet experience, ideal for precision applications. Application: The 370 silent water pump is designed for use in remote-controlled boats requiring water cooling for water-cooled motors without a suction rudder. It is also suitable for remote-controlled aircraft carriers, warships, battleships, and other vehicles that require water cooling for electric motors and ESCs. The 370 motor operates within a voltage range of 3–6V and can be powered directly from the receiver. Compatible with 6S (7–28V) battery systems using a 5V power supply for the pump. Power Control: A switch can be installed between the pump and power source to easily turn the pump on or off as needed. Performance Test: Tested to operate continuously for 15 hours at 5V. The pump remains within safe temperature ranges during prolonged use, ensuring stable operation.
