Dimensional Drawing
Â
12V water pump, generally refers to a micro direct current water pump powered by DC 12V.
Micro water pump, refer to: each has one outlet and inlet that can out and in, and inlet can form vacuum or negative pressure continuously; outlet form larger output pressure; The working medium is water or liquid; A machine of small size. Compared to the alternating current water pump, direct current is safer, and the size is smaller and convenient. Micro DC water pump mainly applied to water treatment. environmental protection.medical treatment.scientific laboratory etc, that need to meet small size.low noise.low power and so on, it can be widely used in water circulation.cooling.raise.transfer.pressure boost.mist spray.sprinkle.transport and so on.
