1) electronic components are used for reversing without using carbon brushes.

 2) using high-performance wear-resistant stainless steel shaft, the shaft sleeve is integrated with the magnet through injection molding to avoid wear, and the service life is greatly enhanced (it can be up to 10 years without maintenance);

 3) the stator part and rotor part of the water pump are completely isolated, and the stator and circuit board part are encapsulated with epoxy resin, which is 100% waterproof; It can be used by amphibious 2!

 4) the rotor part adopts permanent magnet, the water pump body adopts environmentally friendly materials, low noise (less than 35dB), small size, high efficiency, low power consumption;

 5) various required parameters can be adjusted through the winding of the stator, and wide voltage can be operated, for example, 12V can be modulated with 4m head;

 6) water pump fixed base with silicone base.

  Instructions for use:

   1. Overpressure operation is strictly prohibited. It is strictly prohibited to exceed the maximum voltage specified by each. If the battery is fully charged, if there is no pressure limiting measure, it will be seriously overloaded. If you cannot guarantee your own power supply voltage, Please test it first.

    2. Do not use AC power supply, router power supply, computer Cat Power supply and many other similar ones are AC and cannot be used!

   3. Ripple problem (the most prone to problems): Many DC transformers are half-wave rectification, and the result is that many AC components are mixed in DC, and the water pump must be broken! Brushless pump must be full wave rectifier! If you don't understand, please consult a professional!

   4. Lift problem: if the lift is 4 meters, it does not mean that the power supply can spray 4 meters high, but the lift points out the vertical height of the water column in the water pipe after the water inlet is connected to the water pipe. The jet height is much lower than the lift!
