Without using electronic components reversing brushless DC pump, without the use of brush commutation, using the high performance ceramic shaft and ceramic sleeve, sleeve whole will avoid wear and magnets by injection. Therefore, brushless DC magnetic pump life greatly enhanced. Complete isolation of the stator part and the rotor part of isolated magnetic pump, stator and circuit board using epoxy resin potting, 100% waterproof, some with permanent magnet rotor and pump body with environmentally friendly materials, low noise, small volume, stable performance. The parameters can be adjusted by the winding of the stator, which can be operated with a wide voltage. Advantages: long life, low noise up to 35dB, can be used for hot water cycle. The stator and the circuit board part epoxy potting and completely isolated from the rotor can be installed underwater and completely waterproof, water pump axis adopts high performance ceramic shaft, high precision, good shock resistance.
