DC Pumps [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

Hi all,

We're doing the pump for a hot water heating system. Not our design for the 
heating system, and against some of our recommendations, but the folks have 
gotten themselves into a large wood boiler located in an out-building. Both 
the plumber and I have figured they need about 6 gallons per minute and 
about 12 - 14 feet if head. (this is just for from the boiler to the 
storage tank inside. We'll be using El Sids for the radiant loops.)

Anyone know of a pump that will do this with 220 degree water (usually 
cooler, but could get this hot.)

I'd really like a brushless DC unit. The battery bank is at 48V, but we can 
also do 24 or 12, either with a converter, or direct wire if the amp draw 
is small enough. I've been down the brush road, and for pumps that see a 
few thousand hours a year, it's not the way I want to go anymore...

The AC unit the industry would normally use is a Taco 008 cartridge 
circulator which uses about 90 watts.

Thanks for any help.

Jeff
