H2O Injection Pump?

[chauvin at ghg.net]

Bob,

You can look at either Shurflo or Flojet pumps.  The Flojet D7135B7011 is 
listed in the brochure they sent me, 100 PSI diaphragm, 12VDC, made out of 
"chemical resistant materials."  It's not submersible, though - has 3/8" NPT 
connections.  Perhaps a bit of top-cylinder lube added to your water/alky mix 
would help lubricate the seals?  Redline sells some, I think, or maybe Marvel 
Mystery Oil.  I'd also use distilled water instead of tap.  I don't have any 
info offhand on the Shurflo.  The highest pressure one I've seen from them is 
60 PSI.  I called them & asked if they had anything that would handle a 
water/alcohol mix, but they said none of them could handle any flamables, try 
Flojet...
