A basic introduction to Magnetic Drive Pumps


Magnetic Drive Pumps is a new type of sealless pump that uses the principle of permanent magnet drive technology to achieve non-contact transmission of torque. There is no mechanical connection between the driving shaft and the driven shaft, and no dynamic seal exists in the structure, so this type of Magnetic Drive Pumps has no seal and can achieve zero leakage, especially suitable for conveying flammable, explosive, and volatile, toxic, corrosive and precious liquids. Magnetic Drive Pumps are mostly used in occasions where the pump can only leak slightly or even no leakage, as well as in high vacuum occasions where mechanical seals are difficult to handle. In recent years, Magnetic Drive Pumps have been widely used in petroleum, chemical, electroplating, pharmaceutical, food, paper selection, printing, and dyeing industries.

What are Magnetic Drive Pumps?

A Magnetic Drive pump is a kind of centrifugal pump that realizes non-contact torque transmission through magnetic drive and replaces a dynamic seal with a static seal, making the pump completely leak-free. Magnetic Drive Pumps are isolated and driven by magnetic couplers. Inner magnet of Magnetic Pumps is mounted on the pump shaft and sealed in the pump casing with a containment shell made of non-ferromagnetic material; Outer magnet is mounted on the motor shaft and is driven by the motor. The driving torque is transmitted by outer permanent magnetic coupling to an internal magnet that moves the impeller.

The bearings are made of self-lubricating materials and lubricated with the liquid to be sent. Magnetic Drive Pumps are suitable for conveying toxic and harmful, flammable, explosive, highly corrosive, and valuable liquids without particles. Magnetic Drive Pumps adopt an independent lubrication system, and the structure is isolated from the liquid to be sent. It is suitable for conveying high-temperature liquids (450°C).

Structure of Magnetic Drive Pumps.

Magnetic Drive Pumps have a compact structure, beautiful appearance, small volume, low noise, reliable operation, and convenient maintenance. Magnetic Drive Pumps are suitable for petroleum, chemical, pharmaceutical, smelting, electroplating, environmental protection, food, national defense, and other industries.

Magnetic Drive Pumps could be made of stainless steel ,duplex SS2205,deplex SS2507,depending on the detailed application and pumped liquid.
