DC SUBMERSIBLE WATER PUMP

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 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.

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 when using:

1 Work at over-voltage is forbidden. Voltage can be highly more than rated voltage for Battery with more than 5AH at full capacity when there is no voltage-limitation measure. Pls test the supply voltage before working if you are not sure about it.

2 No direct AC Power supply.

3 About the Max static head. Pump with 1.8m head doesn't mean that it can spray as high as 1.8m when connecting with power supply. The real mean of head is that the vertical height of the water column in the plumbing. Spray head is much lower than head.

4 Regulated power supply and switching power supply are advised for more than 0.8A for a certain margin.

5 Pump is not allowed to disassembly unauthorized. Ceramic shaft and sleeve are precisely installed and it's difficult for non-professionals to reassembly. We are not responsible for quality problems caused by this.

6 Ferromagnetic impurity and particles should not be in pump for they affect magnetic actuator and bearing friction. Pump should be promptly cleaned when transporting media that is easy to crystallize or precipitate( Clean operation: pumping clean water for 1min). Pls filter articles before inlet when pumping fluids with solid particles.

There are several notes about use of pump product:

1, as micro brushless dc pump, land use or submersible installation can be both OK, but it cannot be self-priming, just make sure that fluid can actively flow passing through inlet/outlet because pump works via centrifugal force of high-speed rotation of impeller inside (push/throw fluid out). No long-time dry work without fluid, or it may damage the pump.

2, voltage of power supply should be stable and much higher voltage is prohibited, or pump's circuits inside may be burned.

Directly connected with solar panel as power supply is not advised for the real vol. of power supply is not stable and change along with environment such as sunrise, etc; also, if battery with capacity of more than 5Ah is used as power supply, pre-measurement of real voltage is advised. It's because the real voltage of battery may be much higher than rated voltage when battery is in full charge & without voltage-limitation function. Please pay attention.

3, pump can continuously work when fluid temperature is lower than 60C; if higher, intermittent work is more advised as kind of rest and maintenance.
