Cannot operate simultaneously at max temp and pressure. HC series: Highly corrosive chemicals pH 3 to 11 at temperatures to 200F or pressures to 60psi. Note: Be sure to look at the published specs very closely before choosing a pump for your application. I use the 2P042 which is rated at 150F at 0 psi or 110F at 50 psi and have found no problems with the pump dealing with 170F wort. Be aware that manufacturers build in generous padding to their specs to keep them safe. Your mileage may vary. Prices as of First Quarter 1994. May change without notice. I cannot supply the address and phone of Grainger because they have no central place, they have offices in *every* major city in the US. If you do not have one near you, Email me cities around you and I will look them up in my catalog. The do not do mail order, you go down to the local office and pay for it and walk out with with it. (Since this was written, a central phone for Grainger has been obtained, but they still do not do mail order 1-800-323-0620) You can also find these pumps or others similar at surplus houses: Herbach and Rademan 18 Canal St. P.O.
