Monel handles dilute HCI day-after-day in Dowel! equipment-scrubbing units
Do well Incorporated used to have a problem with the pumps on t h e i r special tank trucks.
The pumps circulate solvent from the tank trucks to the interior of industrial equipment to dissolve o u t rust and scale. T h e solvent usually has a dilute hydrochloric acid base. T o prevent corrosion of the plant equ ipment , specific inhibitors are used a n d the solvent is introduced under s t r i c t control of temperatures and exposure t imes.
The pumps, how ever, were a different matter. Centrifugal force a n d high velocities stripped protective coat ings from impellers and nullified the effect of inhibitors inside the p u m p . Was there a durable, corros ion-res is t ing material that could withstand these

condi t ions? Dowell 's tests of many materials provided an answer . . .
Mone l * nickel-copper al loy
Monel alloy, with its inherent resistance to dilute hydrochloric acid, is used by Dowell for pump impellers, stuffing box seals and shaft sleeves as well as for certain storage tank accessories.
You, too, m a y find Monel nickel-copper alloy a n answer to your difficulty. Get the facts. Ask for Bulletin T-29, "Resistance of Nickel, Monel and Other High Nickel Alloys to Corrosion by Hydrochlor ic Acid, Hydrogen Chloride a n d Chlorine."
