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?

No, if you want to connect a pump on solar panel, we recommend you use our 3 phase pump which has the External circuit board.

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. 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 below the liquid surface)

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

3. Preventing any hard particles entering the pump.
