I like the Vortech MP series alot, but they are not as efficient as some of the others.......

This likely has to do with the magnetic transfer loss through the glass vs a direct drive system.
But they look nicer, are cooler, and very user friendly.

Still, most of these low pressure high flow pumps tend to be a lot more efficient than many other types of water pumps.
