[RE-wrenches] Lorentz Pumps

[Jeff Lahl]

We have 1 Lorentz installation in Haiti and about 9 in West Africa - pumping around 10,000 gpd.  Started using them a few years ago because we were having lots of problems with Grundfos.  To date, I believe we've had problems with 
1 controller and 1 pump. (not sure, but a wiring error on the part of our local techs might have caused one of these problems) We're now buying from American West Windmill and Solar in TX (800530-4744) and have had good service from them.  For our next round of systems, we'll probably be looking at Sunpumps as well.

Greetings Wrenchies;

I have had a few inquiries for larger flow rate pumps, and was wondering 
what the latest on Lorentz pumps was.  They show some commercial models 
with high flow rates (30,000gpd) but I haven't gotten any response from 
the company directly.
I have three questions:
Are there any good in country distributors?
are they worth giving a try?
and finally, is anyone actually selling any solar pumps, or just taking 
a lot of phone calls that ultimately lead no where (like us)?

Thanks in advance as always,
