What's better the new Danner Pro hy-drive pumps or the regular danner mag-drive pumps for a return pump from my sump? Anyone have a opinion? I could buy either in a 2100 to 2400 gph for about the same money. Which is better buy? thanks

The Hy-Drives use half the Amps to run. So they are cheaper on electricity and run cooler.

I love danner and the regular mags, but the hy-drives are crap.
the impellors are wrapped in cheap stainless with the copper windings in the impellor. within a few months, the steel wears thin and exposes the copper. the 2100's even have the windings exposed directly to the water at each end of the impellor.
I manage a salt shop and we went to all hydrives for the systems. within 4 months, all the pumps (and the replacements) were dead and the main coral system had readable amounts of copper in it.
we switched over to the quiet one line of pumps.

These images are from the Marine Depot site. Lokk at what the pumps actually are. Resun. Not exactly known as a high quality pump brand.

its been quite sometime... Have the Hy drives gotten any better? how would you compare the 2100 to a Reeflo Tarpon?
