Brushless submersible pump good.

Brushless DC pump refers to the use of direct current 4.5V ~ 24V to drive the brushless motor operation, brushless motor rotation drives the impeller rotation, so that the liquid pressure increases to achieve the role of liquid transmission machine.

1, motor brush pump: brush motor, short life, loud noise, electromagnetic interference, poor sealing, can not dive work
< br >
2, DC brushless pump: brushless motor, long life, low noise, no electromagnetic interference, good sealing, long-term diving work

3, the traditional brush water pump and motor brushless water pump, the structure is because the motor shaft core and the rotor impeller are directly connected, the booster pump is the shaft sealing method, the work, the shaft core and the gasket are direct friction, the life is very short.
