I really dislike mag drive pumps

[Bruce Burnett]

I have had a number of mag drive pumps, never had a failure. I have found a dc pump with the same head pressure and volume also produce heat. On a return or a skimmer requiring pressure you can't beat a mag. The one advantage a dc pump has is low voltage in the water.

Ive had many pumps over the years. Out of them all I absolutely dislike mag drive. Every time i turn them off they wont restart! How i get them going again is to stick a screw driver in the propeller to get it to turn. Not to mention they are so loud! And they heat the water so much and are huge energy consumers. I wish people would stop reccomending mag drives.

A lot of times mag drives are rebranded over and over. Sca-302 has a mag 5 on it and its the same problem, doesn't restart unless you give it a push.

My most favourite that ive tried as an in sump pump is the Eheim. Never cleaned it, had it more than two years, always restarts! Not only that its queit and consumes low power.

My next pump will be a little giant or iwaki. These pumps are reliable, if you want an external pump.

The problem is the head cover called (velute) wears out were the impeller rubber end cap goes in the front velute. That over time wears out and the pump has issues on restart. I have gone through a few of these but since the pump has a 5 yr warranty, they just send me new ones. But according to Danner Mag this pump is not meant to be used with a on/off setup. I have switch my main pump from the Mag18 to the EcoTech Marine Vectra M1 . and have not had no issues ever again.
