Now will send it in plain text...

I'm not an electrician, but I have had some experience using VFDs 
<http://www.phaseconverterinfo.com/phaseconverter_vfd.htm> as phase 
converters.  I believe that either Delta, or Y is very rare (don't know 
which one), but I'm sure the VFD 
<http://www.phaseconverterinfo.com/phaseconverter_vfd.htm> can handle 
it. VFDs <http://www.phaseconverterinfo.com/phaseconverter_vfd.htm> are 
sized by horsepower and it is always better to oversize slightly if you 
can.  For a pump load, you must oversize by one.
