A mag-drive or magnetic drive pump have a much lower head than a direct drive. It uses a magnet that is able to turn the impeller clockwise or counter clockwise. The impeller is basically flat which enables it to turn in either direction. However the flat blade makes the impeller inefficient and in return can only produce a low to medium head. If the impeller was more curved and turned only in one direction like a direct drive it would have a higher flow and higher head.

Mag drives can last a long time and are very energy efficient. Since the mag drive motor has a long life expectancy the impeller may need to be replaced within its lifetime. The pump is smaller and lighter than that of a direct drive. These pumps are great for fountains, spitters and for moving water in small to medium ponds and are made for continuous use.
