DURIRON
Soi to f
a high-silicon iron, containing a p p r o x i m a t e ly 14.5% silicon. H a n d l e s almost any commercial corrosive. Practically unaffected by sulfuric, nitric and acetic acid at any strength or temperature. Ask for bulletins 1 1 and 810.

DURICHLOR a high-silicon iron similarto Duriron butwith much greater resistance to h y d r o c h l o r i c acid and its compounds, especially at higher temperatures and concentrations. Ask for bulletins 50 and 810.
DURIMET a high n i c k e l high chromium — m o l y b d e n u m— copper—siliconlow carbon stainless steel. Some of the corrosives it successfully handles include sulfuric and sulfurous acid, oleum, caustic and bleach solutions. Ask for bulletins 1 10-2 and 811.
CHLORIMET The wet end parts of this Model 40 Durcopump —volute, casing, impeller, head,and shaft sleeve—can be easily changed from one corrosion-resisting alloy to another. Without changing the operating characteristics or disturbing the motor, bearings or alignment, you can give your Durcopump the ability to handle an entirely new group of corrosives. Model 40 Durcopumps are available in capacities up to 2000 GPM and for heads as high as 230 feet. 28-GM

# 2 —nickel base, high molybdenum alloy; # 3 ^ n i c k e l base, high molybdenum, high chromium alloy. Both of these are high strength, machinable alloys. Chlorimet # 2 handles hydrochloric acid in all concentrations and temperatures. It is excellent for hot sulfuric acid under reducing conditions and for wet hydrogen chloride gas. Chlorimet # 3 handles most acids under oxidizing conditions, various salt solutions, also hot sulfuric in concentrations of less than 35 % . Ask for bulletins 1 11 and 81 1.
