The biggest feature of the miniature DC water pump is that it is compact and light, easy to install, low noise, low power and high efficiency. Widely used in garden landscaping, small fountain landscaping, grassland irrigation, aquaculture, small household appliances applications, etc., covering many fields such as industry, agriculture, chemical, transportation, IT, construction and home appliances.

In order to ensure the normal service life of the micro brushless DC water pump, to maintain stable performance and avoid accidents and loss during use, pay attention to the following points when using:

1、Avoid frequent switching:

　　Do not switch the micro submersible pump frequently. This is because the recirculation will occur when the electric pump is stopped. If it is turned on immediately, the motor load will start, causing the starting current to be too high and the winding to be burned out. Due to the large current at startup, frequent start-up will also burn the submersible pump motor windings;

2、the product belongs to the centrifugal pump, must be installed below the liquid level;

3、It is strictly forbidden to use liquid with 0.35mm impurities and magnetically conductive particles;

4、It is strictly forbidden to use when there is no liquid in the pump to prevent the liquid from telling the rotation to produce high temperature and wear internal structure;

5、when using in low temperature environment, please ensure that the use of liquid does not appear frozen or very sticky;

6、must meet the situation of low temperature frost heave, to prevent the internal water pump ice cracking in winter;

7、The internal clearance of the DC brushless water pump is precisely controlled. Do not drop it, otherwise the noise and vibration will increase.

8、Do not let the brushless DC pump work for a long time

　　In order to avoid long-term overload operation of the pump, do not pump water with a large amount of sand and observe the current value on the nameplate at any time. If the current is too large, stop the machine. In addition, the dehydration operation time of the electric pump should not be too long, so as to prevent the motor from overheating and burning.

9、diligent inspection, find problems and repair in time

　　Always check the motor frequently. If the lower cover is cracked or the rubber seal ring is damaged or invalid, it should be replaced or repaired in time to prevent water from seeping into the submersible pump.

10、The direction of rotation of the motor should be correct:

　　The direction of rotation of the motor should be clarified. There are many types of submersible pumps that can discharge water during forward and reverse rotation, but the water output is small and the current is large when reversing, and the motor winding can be damaged if the reversal time is long.
