Magnetic Pump: Fusion of Technology and Tradition

In the modern industrial field, the magnetic pump has become a shining star in the water pump family with its unique performance and wide application fields. The magnetic pump, an innovative product that applies the working principle of permanent magnetic coupling to the centrifugal pump, shines in many industries with its remarkable features such as full sealing, no leakage, and corrosion resistance.

The magnetic pump is a special type of pump that uses the electromagnetic principle to drive the liquid. Its working principle is to transport the liquid from the low-pressure area to the high-pressure area through the magnetic force generated by the electromagnet. The magnetic pump is mainly composed of three parts: the pump body, the magnetic transmission and the motor. Among them, the magnetic transmission is the core component of the magnetic pump, which consists of an outer magnetic rotor, an inner magnetic rotor and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non-magnetic materials, drive the inner magnetic rotor connected to the impeller to rotate synchronously, and realize the contactless synchronous transmission of power. This design cleverly transforms the dynamic seal structure that is prone to leakage into a static seal structure with zero leakage, thereby completely solving the problem of leakage in traditional centrifugal pumps.

Magnetic pumps can be divided into AC micro, brushed DC and brushless DC types according to different driving modes. AC micro magnetic pumps are popular for their low price and numerous manufacturers; although brushed DC magnetic pumps are cheap, the carbon brushes are severely worn after hundreds of hours of continuous operation, affecting their service life; brushless DC magnetic pumps use high-performance wear-resistant ceramic shafts and ceramic sleeves, which greatly enhance their service life, low noise, small size, and stable performance, making them an ideal choice for hot water circulation and other fields.

The main features of magnetic pumps include: fully sealed, leak-free, corrosion-resistant, compact structure, easy maintenance, safe and energy-saving. These features make magnetic pumps widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment and other fields, and they have become ideal pumps for creating leak-free, pollution-free civilized workshops and civilized factories.

Magnetic pumps play an irreplaceable role in many fields with their unique performance advantages. In the petroleum, chemical and other industries, magnetic pumps are used to pump flammable, explosive, toxic and precious liquids to ensure production safety; in electroplating, environmental protection, water treatment and other fields, the non-leakage characteristics of magnetic pumps effectively prevent the pollution and leakage of the medium and protect the environment; in the medical, food and other industries, the corrosion resistance of magnetic pumps ensures the purity and hygiene of the medium.

In order to ensure the long-term stable operation of the magnetic pump, it is necessary to perform regular maintenance and maintenance on it. To accurately select the flow rate and head of the magnetic pump to ensure that the pump is in the best performance state during use; to maintain the lubrication effect, frequently check the quality and oil level of the lubricant to ensure that the bearings are fully lubricated; to strengthen the maintenance of wearing parts, regularly check and replace severely worn parts to extend the service life of the magnetic pump.
