Product Description: 220V AC voltage can not be used directly! - Brushless, permanent magnetic rotor. Adopt high performance ceramic shaft. - It is smooth operation, high efficiency, good performance, long service life, - Can be a long time continuous work, low noise, safety and environmental protection. Please Note: 1. Use with DC 12V 5A or DC 24V 5A power adapter with water pump 2. The pump needs to be fully immersed in the water, otherwise the pump will enter the air and the pumping will be intermittent. Usage: 1. Female plug type: The water pump cable is attached with a female plug (size: 5.5x2.1mm), can be powered by a DC adapter directly. (Note: The DC brushless pump is a centrifugal pump, the pump water flow with the increase of the head decreases. No diving without self-priming function, prohibit no water using.) Specification: - Pump type: DC brushless water pump - Voltage: 12V 24V DC - 12V: 3.72A, 45W - 24V: 3.2A, 77W - Color: Black - Max water flow Rate: 12V 2500L/H, 24V 3500L/H - Max Water Head: 12V 8M / 24V 10M - Plug type: 5.5*2.1mm female plug - Ambient temperature: -40~100C - Operating Humidity: less than 90%RH - Liquid temperature: -40~100C - Using liquid: water or Nonflammable liquid with good fluidity - Operation place: Medical, fountains and so on - Working Lifespan: 30000 hours - Noise: 40DB - Waterproof: IP68 - Package Including: 1 x dc brushless water pump Using Note 1. Please use the suitable voltage according to the specifications, do not beyond the voltage range. 2. Do not use with strong acidity, alkali and other damage liquid. 3. Water head does not mean the spraying height, but means the height inside of a pipe. 4. The max flow rate is based on the flow of horizontal condition in the standard test, every buyer uses it in different applications, so the water flow will be different (less than the max flow). 5. Our pumps are not self-priming pumps. It must be installed below the water level or submersible. 6. DC pumps are safety, stable, long lifespan, energy saving. We suggest you use it instead of AC pumps. 7. Continuous running is no problem! The pump will have a super long lifespan if correct using. 8. The diameter of pipe will directly affect the flow rate. 9. Any problem, please contact us before you open a dispute, Thanks! Product Real Photos Application:
