Difference between magnetic pump and centrifugal pump

(1) The difference between magnetic pump and centrifugal pump is that magnetic pump has no shaft seal, while centrifugal pump has shaft seal.

(2) Functionally, the magnetic pump has zero leakage, while the centrifugal pump will leak after a long time.

(3) Magnetic pump has internal magnetic rotor and external magnetic rotor, while centrifugal pump does not.

(4) Magnetic pump can not transport materials containing foreign particles, it needs to be transported to the medium for lubrication and cooling, while centrifugal pump can.

Magnetic pump

Magnetic pump is also a type of centrifugal pump. It is also called magnetic centrifugal pump, but magnetic drive centrifugal pump (referred to as magnetic pump for short). This pump applies the principle of modern magnetic mechanics, that is, when the motor drives the outer rotor (referred to as outer magnetic steel) assembly to rotate, the magnetic force line passes through the isolation sleeve and drives the inner rotor (referred to as inner magnetic steel) assembly and impeller to rotate synchronously. As the medium is enclosed in the static isolation sleeve, the purpose of pumping the medium without leakage is achieved, Solved the leakage of the shaft seal of mechanical drive pump, and designed a new industrial special pump with full seal, no leakage and no pollution. The magnetic pump features full sealing, no leakage and corrosion resistance. It is widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense and other departments to transport flammable, explosive, toxic and precious liquids. It is an ideal pump type to create a leak free, pollution-free and civilized factory.

Centrifugal pump

The drive of the centrifugal pump is to connect the impeller shaft of the pump with the electric shaft through the coupling, so that the impeller and the motor can run together. When the centrifugal pump is started, the pump shaft drives the impeller to move together, so that the liquid pre filled between the blades can rotate. Under the effect of inertial centrifugal force, the liquid body moves radially from the center of the impeller to the periphery.
