<P class=MsoNormal><SPAN style="COLOR: #1f497d">Were currently ordering 3
pump systems for West Africa and ended up using both Grundfos SQF and
Lorentz. Weve had good luck with Grundfos in the past but our needs in
some cases exceeded what the SQF could pump so will be trying Lorentz for the
first time. I was hesitant after hearing some unfavorable things about
Lorentz but have been told that the latest versions have the problems worked
out. Im afraid I dont recall what the original problems were supposed
to be but Im sure others on the list will contribute their experiences.
It will be interesting to see how both systems hold up in the same
environment.<o:p></o:p></SPAN></P>

situation: Total Dynamic Head = 212 feet; 48.5 degrees north latitude; need
