So why would you want to choose a magnetic drive pump? They are a suitable pump if the application in question requires the complete containment of the process fluid being pumped. For a magnetic drive pump, instead of having a shaft that passes through the body of the pump, which requires a dynamic seal, the pump has one assembly of magnets attached to the shaft of the motor and a second assembly of magnets attached to the impeller inside the pump body. When the motor rotates, the magnetic field generated between the two magnets means that the impeller turns in the pump body. The liquid to be pumped is therefore contained within the hermetically sealed pump housing without the risk of any leaks from the shaft seal.
Advantages of magnet drive pumps:
- Very low risk of fluid emissions from the pump
- Low maintenance seal less design
- No pump to motor alignment problems
- Quick wet end and pump head service replacement
