I started seeing these pop up on ebay a few months ago:

http://www.ebay.com/itm/Brushless-DC24V-Magnetic-Drive-Pump-640GPH-Motor-Speed-Variable-0-100-50C-2465-/350702846479?pt=LH_DefaultDomain_0&hash=item51a784 c20f

They look heavier duty than the "Sous Vide" FDA pumps that a lot of chinese sellers have been advertising for a while. Anyone have any input?

The speed controller is a rather interesting concept. Subscribed if anyone tries one out.

I just asked the seller if they are food grade and if they can handle temps in the 212degree f range.
Will tell the outcome

I've seen guys put ceiling fan speed control switches on their chugged/march pumps. They have lots of speed control that way.

They look like the pumps from here:

"Max operating temperature up to 100°C/212F with external circuit board"

Odd that it mentions the external circuit board, that leaves it unclear if that means the pump is good to 100ºC or if the board/controls are good to 100ºC.

6.5m of head is not insignificant and it is nice that the units come with their own power supply. Wonder how easy it would be to hack into and extend the wires to a control panel?

The fact that they are completely sealed is nice...no neeed for a splash shield. They do indeed look like the gtreatbreweh pumps but without the stainless npt threads...the control board is likely just 120 to 12 v converter with the potentiometer, and should be easy to hack. I'm interested if they hold up to their claims. Might male for a nice new HLT pump that mounts directly to the bottom drain valve.

It's not clear to me that variable speed control is particularly useful in a mag drive pump that should work fine when regulating the output flow with a valve. I certainly would not pay a premium for it.
