First of all, we do some classification of the pump, we can basically know how the magnetic pump and centrifugal pump are named. Pumps can be divided into many kinds, and as we mentioned earlier, there are the following ways to classify pumps. Classified by structure, material and use. Magnetic pump and centrifugal pump are classified according to structure, such as magnetic pump, centrifugal pump, self-priming pump, submerged pump, screw pump, diaphragm pump and so on. So what are the essential differences and similarities between these two commonly used pumps?

First, what they have in common.
1. Both magnetic pumps and centrifugal pumps belong to vane pumps, so they both have impellers.
2. They all use the principle of centrifugal force to make the liquid produce energy, so they are all called centrifugal pumps (magnetic pumps can be called magnetic drive centrifugal pumps).
3. Their performance curves are all the same.
4. They can all be divided into vertical and horizontal ones, and they can also be made into self-priming ones.

Second, the difference point.
1. The difference between the centrifugal pump and the magnetic pump is that the magnetic pump has no shaft seal (or machine seal), and the centrifugal pump has a shaft seal.
2. Centrifugal pumps do not have internal magnetic rotors and external magnetic rotors, but magnetic pumps have all.
3. Functionally, the magnetic pump has zero leakage, while the centrifugal pump will leak if it takes a long time.
4. The magnetic pump can not transport the material containing impurity particles, because it needs to be lubricated and cooled by the conveying medium, while the centrifugal pump can.
