12V Mirco Brushless dc pump DC micro pump maintenance-free Low nise Long life For  computer cooling system Garden fountain

This is a high-quality made DC mini submersible pump
Built by a brushless motor so that quieter and last longer than a non-brushless pump, plus, it will not generate electric spark like the non-brushless pump does, so it's safer, can be used to pump oil (inflammable fluid)
Super long working lifespan (more than 30,000 hours), maintenance-free
Small size, low consumption, low noise(less than 35db)
Submersible and entirely waterproof, easy to install and use
Can be used to pump water, oil, acid and alkali solution
Variety of power supplies: solar panel, DC electric source and battery

For Pump, Water plays three roles: 1, the medium being pumped; 2, coolant of pump;3, lubricant of pump.

Head-Flow curve Graph

How to Choose pump:

1. Make sure the working voltage, current, head and flow. The Max head means the static head. The pump can lift to the max heightwhen there is no flow. If you want special flow at special height, you must choose more higher head than the height you want to pump(refer to the above Head-Flow Curve graph).

2. Make sure the dimension(threaded interface or not, the direction and diameter of outlet and inlet).

3. Working environment(temperature and medium).

4. Other functional requirements, such as time control, motion control, pressure control, flow control, and speed adjustment.

Note:

1. Working at rated voltage. The positive pole is red wire, the negative pole is black wire.

2. This pump is centrifugal pump, it can't vent the air automatically, so it must be operated by submersible installation.(if outside water installation, you should make sure it is installed blow the liquid surface)

3. When blocking, long-running is not allowed.

4. Preventing any hard particles entering the pumps.
