[RE-wrenches] Another pump quesiton

[Sindelar Solar]

Howie,

As far as I know, and I have not researched this, The El Sid drivers 
mate to the pump bodies used with March 809BR and 809BR-HS hydronic 
pumps. The March pumps use brush-type conventional 12 and 24V DC motors. 
I have heard, but can't confirm, that Dan Fieldman developed the El Sid 
(Static Impeller Driver) when he worked at March, or after he left them.

I have both March 809BRs and El Sid 10Bs in my off grid hydronic system. 
Both work equally well, both eventually fail (and not on much of a 
predictable schedule), both are expensive little buggers, and the El 
Sids are noticeably quieter.
