Sequence Dart users?

There's 2 different motors, and they run much diff. tempratures apperently. The Baldor I have is warm, but never hot. There's another motor they have that doesn't have cooling fins around it, forget who makes them, but that one apperently runs hot.

I have the larger Baldor motor and it warm but never hot.

The cheaper AO Smith motor runs much hotter. I believe Sequence has returned to only using Baldor motors but I'm not 100% on that.

All three of mine put out different amounts of heat, one is like yours, a little too hot to touch for very long another I could hold onto all day long, it warm but not hot and the third falls in between.

Interesting how it's so variable. Robb, are all 3 mounted similarly in terms of the inlet side plumbing? I use 2" plumbing on the inlet side, and this is huge .. they say you can step it down to 1-1/2" without consequence and I've seen this, so I would have thought that the 2" compensates for the one 90 degree bend I have right at the bulkhead. But then I do have a strainer on the bulkhead inside the sump. Maybe I should try removing this and see if I notice a difference.

I think mine is a Baldor motor. It has a fan on the end, I thought the AO motors were fan-less. But what's weird is that the motor core is much smaller than other Dart pumps I've seen that have fans. So it seems there are more than just 2 options out there for the same pump model..

I tried putting a 4" box fan on the floor blowing laterally onto the pump to see if that would cool it off, it actually didn't, so I took it off. Might as well save a few watts on electricity if it's not doing anything.

I think mine is a Baldor motor.

All three are mounted in a similar fashion, all with 2" intake plumbing, 1 1/2 discharge, all down hill fed to the pumps. The front and back one are the closed loop pumps fed from the bottom of the tank and the middle is the return pump, which through two 90's has about a 2/3 drop from the sump to the pump.

None of mine are the ones with the Baldor Motors.

Well, aren't I observant. Looking at the pump last night I noticed it said "AO Smith" on it. Sooooo .. I guess that sort of explains that. For what it's worth, it has a fan though. I keep reading that AO motors don't have the fans and it's the Baldor motors that do. Well, I guess the AO motors do have fans - they just don't do much..
