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. Long Continuous Operation: Equipped with a JR plug for receiver compatibility, the pump operates continuously for up to 15 hours at 5V without interruption, maintaining reliable performance. Efficient Performance: The pump may generate heat during operation, but this remains within normal operating limits and does not affect functionality or longevity. Low Noise Operation: Designed for quiet performance, the pump ensures minimal noise, making it suitable for noise-sensitive 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 operates within a voltage range of 36V and can be powered directly from the receiver. Compatible with 6S (728V) battery systems using a 5V power feed. Ideal for remote-controlled aircraft carriers, warships, battleships, and other vehicles requiring motor and ESC water cooling. On/Off 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 run continuously for 15 hours at 5V. The pump maintains normal operation throughout, with temperature levels staying within safe and expected ranges. Pump Specifications: Outlet diameter: 3.95mm.
