DC brushless pump installation and cautions
|
|
1. The positive pole is red or brown wire; the negative pole is black or blue wire.
2. Overvoltage, reverse wiring will burn the motor. Confirm your power voltage before connecting the pump, to ensure that it works under the rated voltage.
3. BLDC pump is not self-priming pump. It must be installed under the liquid level or completely submerged in the liquid.
4. Keep the water clean, prohibiting impurities from entering the pump. Some device such as filter will be useful.
5. Dry operation (operation without liquid in the pump) will damage the pump.
6. Head means water's height inside of a pipe, not the spraying height.
7. Flow rate is horizontal rate, if you need a certain height, the flow rate will be reduced.
8. When the head is at the max height, the flow rate will be zero. You could choose the suitable pump refer to our Performance Curves.
9. Ensure the water clear, regular checks can increase pump's lifespan.
