Magnetic drive pumps are a great alternative to traditional mechanically sealed pumps especially when pumping corrosive, dangerous, or expensive fluids. While usually categorized as a centrifugal pump the addition of a magnetic coupling can make troubleshooting slightly different than your standard mechanically sealed pump. The additions of the magnets add another layer of diagnosing any system issues.
There are many factors that can affect the performance of a magnetic drive pump. Magnet decoupling is a concern that is not present in a mechanically sealed pump but can happen in a magnetic drive pump. Since most magnetic drive pumps use the fluid within the pump as its lubrication the bearing system within the pump is much different than a sealed pump. Conversely, magnetic drive pumps eliminate mechanical seal alignments, maintenance, and repair.
