Hello,
Regarding the Potential heat issue with one of the vortec's pump. I found this info from the ICECAP forum.

1. re hot running VorTech Pumps: If you have more than one, switch the wet side and see if the problem follows the wet side. If it does, check to see if it's binding up.
It may be that you need to adjust the spacer on the dry side to a thinner glass setting which moves the magnets slightly farther from each other, which may stop the heat problem. If one VorTech is noticeably harder to pull from the glass than the other pump, I'd try this approach.
The comment about looking for a bent pin in the pin spacer or signs of rubbing against the pump's motor driven magnet on the center of the pin spacer is very important. Friction will make the motor work harder and hotter.
