FW: DC Pumps [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

Well, I'm getting close. This page has what looks like a nice pump, but 
almost twice the head I need. Only problem is it uses more watts than an AC 
pump with the correct head!

Thought some of you might be interested in it if you have higher head 
applications.

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
