What is a magnetic coupling pump? How is the magnetic coupling pump working principle?

Pumps used for transferring, circulating or filtering liquids from one place to another are equipment that we encounter in almost every application that includes the word “liquid”.

Pumps are not only classified according to their types and areas of use, but also according to the type of liquid they carry. For example, if the liquid to be pumped contains a dangerous chemical substance or if there are situations where the pump needs to be completely immersed in the liquid, then different pump types are applied because the process is different. At this point, the use of a magnetic coupling pump is required. Let’s briefly describe what a magnetic coupling pump is. Magnetic coupling pump is a type of pump based on magnetism. Magnetic coupling pumps are the name given to the type of pump designed to pump liquids containing toxic and other dangerous substances without the use of mechanical seals. The elements flowing over the electricity are kept in a completely closed area and the magnetic force is transferred by the magnet located on the shaft on which the liquid wheel rotates. Magnetic coupling pumps are basically pumps used for hazardous materials, but they also have many advantages. One of the biggest advantages of the magnetic coupling pump is that it does not need sealing equipment. Thus, there is no such thing as the wear of the sealing equipment, which is frequently encountered in pump failures, and since there is no wear, there is no situation that puts the pump in danger. Pumps with magnetic coupling do not have a table entirely based on advantages, they also contain possible dangers. Pump maintenance needs to be done regularly and even more often than other pump types. If the transported liquid contains flammable, toxic, radioactive and processes that threaten human health and the environment, then even a small leak will be a big risk. Magnetic coupling pumps are low cost pump types. In addition, it can be said that the assembly processes of magnetic coupling pumps are easier and faster than other pump types.

Magnetic coupling pump working principle

Pumps with magnetic coupling have impeller and magnets. These magnets are attached to the motor. The magnets are connected to the drive assembly of the pump. When the motor is turned on, it turns the magnet and the propeller rotates thanks to the magnetic force coming from the magnet of the motor. Pumps with magnetic coupling are centrifugal pump types. Let us briefly explain the working principle of the magnetic coupling pump. Here is a balanced magnetic field necessary for a healthy wheel transformation. The external magnet movement associated with the motor shaft moves the internal magnet inside the pump. The internal magnet located here is connected to the fan. As a result of this movement, the fan rotates and the liquid in the pump moves. The internal and external magnets inside the pump are separated from each other thanks to a sealing arrangement, and thus the magnetic coupling pump fulfills its function.
