Magnetic centrifugal pump is a high-tech product that uses the working principle of permanent magnet couplings for centrifugal pumps. It is designed reasonably, has advanced technology, and has the characteristics of full sealing, no leakage, and corrosion resistance. Magnetic centrifugal pump can be widely used in chemical engineering, acid making, alkali making, smelting, rare earth, pesticide, dye, medicine, papermaking, electroplating, acid washing, radio, chemical foil, petroleum, food, film photography and printing, scientific research institutions, etc Transportation and pressurization of rare and precious liquids such as acids, alkalis, oils, toxic liquids, volatile liquids, especially leaky, flammable, and explosive liquids, by units such as the national defense industry. The magnetic chemical centrifugal pump consists of three parts: a centrifugal pump, a magnetic drive, and an electric motor. The key component of the magnetic actuator is composed of an external magnetic rotor, an internal magnetic rotor, and a non magnetic isolation sleeve. When the electric motor drives the outer magnetic rotor to rotate, the magnetic field can penetrate the air gap and non magnetic substances, driving the inner magnetic rotor connected to the impeller to rotate synchronously, achieving contactless transmission of power and converting the dynamic seal into a static seal. The magnetic self priming centrifugal pump adopts an advanced external mixing axial return water pump body structure design, which is composed of suction chamber, storage chamber, volute, reflux hole, gas-liquid separation chamber, and other parts. After the pump is started, under the action of centrifugal force, the remaining liquid in the suction chamber and the air in the inlet pipeline are stirred by the impeller to form a gas-liquid mixture. The mixture enters the gas-liquid separation chamber through the volute, and as the flow rate decreases, it causes gas-water separation, and the air is discharged from the pump outlet. The driving device of the magnetic self priming pump adopts an active magnetic coupling directly installed on the motor shaft, and indirectly drives the impeller on the rotor combination to rotate through magnetic coupling. The pump cavity is completely sealed and there is no leakage. A magnetic high viscosity centrifugal pump is composed of three parts: a disc pump, a magnetic drive, and an electric motor. The energy transfer from the impeller to the liquid flow in a disc impeller centrifugal pump is carried out under the frictional force of the boundary layer of the rotating disc. When the liquid enters the pump, its molecules engage with the surface of the disk, forming a boundary layer. As the pump rotates, energy transfer occurs to the subsequent layer of liquid molecules between the disks. The strong pressure field formed in this way pulls the product out of the pump in a layered manner (i.e. unaffected by fluid fluctuations). According to the physical and chemical properties, wear resistance, and corrosiveness of the conveying medium, the materials of the flow passage components are divided into two categories: metallic and non-metallic
