Waterproof Design: The water cooling pump features a waterproof construction, allowing it to operate reliably even when submerged. It is built for durability and long service life.Extended Operating Time: Compatible with JR plugs and suitable for receiver integration. At 5V, the pump can run continuously for up to 15 hours without interruption while maintaining stable performance.Efficient Performance: During extended operation, the pump may generate heat, but this remains within normal operating limits and does not affect functionality.Low Noise Operation: Designed for quiet performance, making it ideal for applications where minimal noise is desired.Intended Use: The 370 silent water pump is designed for use in remote-controlled boats equipped with water-cooled motors that do not have a suction rudder. It operates within a voltage range of 36V and can be powered directly from a receiver. Compatible with 6S (728V) battery systems when used with a 5V power supply. Suitable for remote-controlled aircraft carriers, warships, battleships, and other vehicles requiring water cooling for motors and ESCs.Switch Recommendation: Install a switch between the pump and the power source. Turn the switch on to operate the pump and off when not in use for better control and power management.Performance Test: Tested to operate continuously for 15 hours at 5V. The pump remains functional throughout the test, with temperature rising to expected levels that are within safe and normal operating range.Product Specifications:- Pump head outlet diameter: 3.95mm- Center hole: water outlet- Eccentric hole: water inlet- Rated voltage: 6V- Operating voltage: 36V- Flow rate at 3V: 1.1L per minute (300ml per minute)- Flow rate at 6V: 1.8L per minute (600ml per minute)- Total pump length (including outlet): 72mm- Motor outer diameter: 24.4mm- Pump head outer diameter: 28mm- Inlet and outlet outer diameter: 3.95mm- Material: Metal- Color: Metallic- Size: Approximately 5 x 3.6 x 1.5cmPackage Includes:1 x 370 RC Water Cooling PumpNote: Other items not included.
