The magnetic drive pump runs continuously, without seals to wear out and is very low in energy consumption. They are filled with epoxy, not oil. These pumps are ideal to power statuary, fountains and small to medium bio filters and waterfalls. The mag drive can be run inline or submerged.
The Hy-Drive is a cross between a magnetic drive and direct drive giving you the benefit of being energy efficient and a greater head height to be used in larger pond applications. The cage that surrounds the actual pump has a built in carry handle and debris screen. They can be set up in a vertical or horizontal position. A Hy-Drive is even more efficient then a Mag Drive once the flow is over 2000 gph. The Hy-Drive is very quite; low maintenance and can run inline or as a submersible pump.
If you have a very high head height, either by having a very long run of pond hose, a very high waterfall or needing a fountain to shoot up water at a high height then you will want to choose a Direct Drive Pump. If you don’t need a very high head height then a magnetic drive or Hy-Drive will save you money. Most Pondmaster Pumps have a generous warranty.
