1.Does the Head mean i can use the pump to pump water(or other liquid) up to the height directly?
No, the pump can lift to the max height when 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). the Head means when you connect a little hose on the output of pump, the max height of the pump can pump, if you do not connect a little hose on it, it can not pump water to the height in AD.

2.Can i connect it on my solar panel?

Yes, you can, but you should make sure the output voltage of your solar panel stable and less than DC12V, or it will damage the pump.

3.Can i dry run the pump(run but not pump water)?
No, Dry run the pump will damage the pump and shorten the working time of the pump.


1.The black box contains the circuit board, it is not a transformer, the input voltage should be less than DC12V. External circuit board is designed for sustaining water temperature up to 100°C.

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

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

4. Preventing any hard particles entering the pump.
