[RE-wrenches] Lorentz Pumps

[Kent Osterberg]

Fellow wrenches,

Problems with Lorentz pumps have been discussed here before.  Yesterday, 
I responded to a no water complaint and found that the Lorentz pump we 
installed in 2007 appears to have seized up during six months of non-use 
(it's for stock water).  This is the second identical failure for the 
same customer.  The pump is in a deep well that it is unlikely to over 
pump and there is a low-water sensor too.  For those of you that have 
installed these pumps, what types of problems have you observed?  How 
long are these pumps lasting?  Thanks any replies.
