The operation of a magnetic driven circulation pump is achieved by installing magnetic materials on the connecting shaft and impeller to attract and couple with each other, without the need for traditional mechanical shaft seals, thus it is completely sealed. The rotational torque of the electric motor is driven by the attraction of the active and passive magnets to drive the blades to work and operate. The biggest disadvantage of the commonly used magnetic drive pump nowadays is that it is absolutely forbidden to operate in the absence of liquid, otherwise the whole machine will be damaged, adding unnecessary trouble and annoyance to the user. The magnetic drive pump of 'Green Ring Pump Industry' does not need to worry about this. It adopts a specially designed specially formulated ceramic bearing, which has extremely strong wear resistance and corrosion resistance, so that its advanced performance and quality safety can be absolutely guaranteed.
