It’s undoubtedly a difficult choice to make between a magnetically driven centrifugal pump and a mechanical seal centrifugal pump! To save you some time and constant Google searches, let’s give you a gist about the main comparison between the two:
- Sealing the fluid
In the sealed centrifugal pumps, the presence of a mechanical seal prevents fluid leakage even while the water pump is in operation. On the other hand, magnetic water pumps do not require a seal since it has a containment shell at the end that ensures a safe enclosure for any leakage to happen.
- Maintenance cost and life
In sealed centrifugal pumps, there is a continuous movement between the parts which are in close contact with each other. This arrangement results in easy wear down of the elements and hence, constant maintenance costs. But, because the magnetic submersible motors do not contain any seal, there’s no need for replacements, which costs less.
- Application of fluid types
The mechanical centrifugal motor is capable of pumping out some hazardous fluid, but there’s always a scope for leakage there. Whereas, magnetic pumps due to their inherent design are comparatively safer for hazardous liquids as there is zero scope of leakage. Also, hazardous liquids are generally more expensive and require safe use, which proves magnetic pumps to be more effective for the purpose.
