Micro pump features (also known as miniature magnetic pump)

Micro AC Pump: AC pump commutation is through the city's 50HZ frequency changes, the speed is low, there is no exchange of electronic components inside the pump, you can high temperature, the same head exchange Pump volume and power is the DC brushless 5-10 times the pump. Advantages: cheap, manufacturers are more Brush DC pump: pump work, the coil and commutator rotation, magnet and brush does not turn, the alternating current direction of the coil is the motor rotating commutator and Brush to complete, as long as the motor rotates the brush will produce wear and tear, the computer pump to run to a certain time, carbon brush wear gap becomes larger, the sound will also increase, continuous operation hundreds of hours after the carbon brush can not play The role of commutation. Advantages: low prices. Brushless DC Motor Pump: Motor-type brushless DC pump is the use of brushless DC motor with the composition of the impeller. Motor shaft and impeller together, there is a gap between the stator and rotor pump, the use of water for a long time will penetrate into the motor to increase the possibility of motor burn out. Advantages: Brushless DC motor has been standardized, a large number of specialized manufacturers, low cost, high efficiency. Brushless DC magnetic drive pump: Brushless DC pump with electronic components for the commutation, without the use of carbon brush for the conversion, the use of high-performance wear-resistant ceramic shaft and ceramic bushings, bushings and magnets by injection molding as a whole will be avoided Wear and tear, so brushless DC magnetic pump life has greatly enhanced. Magnetic isolation pump stator part and the rotor part of the complete isolation, the stator and the circuit board part of epoxy potting, 100% waterproof, the rotor part of the permanent magnet, the pump body with environmentally friendly materials, low noise, small size, performance stable. Various parameters can be adjusted through the stator windings and can be operated at wide voltage. Advantages: long life, low noise up to 35dB below, can be used for hot water circulation. The stator and circuit board of the motor are encapsulated with epoxy resin and completely isolated from the rotor. They can be installed underwater and fully waterproof. The axis of the pump is made of high-performance ceramic shaft with high precision and good shock resistance.
