Feature 1、【Timing Function and Acceleration and Deceleration Mode】This small water pump with 4 gears On/Off timing function. You can choose timing On with 0.5H/1H/2H/5H, and enter acceleration mode for reducing half time of the 4 timing and the OFF time will remain unchanged. You can choose timing Off with 1H/6H/12H/24H, and enter deceleration mode for double time of the 4 timing and the ON time will remain unchanged. 2、【Strong Power and Low Power Consumption】Max flow rate 400L/H, Max lift height up to 9.8ft, Max power: 6.2W. Rated voltage: 5V. 9.5mm outer diameter of water inlet and outlet. Submersible water pump adapts pure copper brushless motor and professional driver chip, high power, energy saving and eco-friendly. 3、【Safe and Quiet】Electric water pump is safe to use with water and electricity separation technology, soft start and water shortage protection. Ceramic bushing makes wear-resistant and ultra-quiet, no interrupt your rest, sleeping and working.
