LINE EXPANDED!
Three new sizes of Model F Centrifugal Pump extend Capacity and Head Three new sizes of Model F "Karbate" impervious graphite pumps are now available to meet the demands of the chemical and metal finishing industries for greater capacities and heads. These are designated as Sizes 22-FAL, 28-FAL, and 31-FAL. Operating at 1750 RPM, capacities up to 150 GPM and heads up to 67' can be obtained. To handle fluids with specific gravities greater than water at the higher capacities and heads, the 2 8 - F A L and 31-FAL pumps arc available with 3 and 5 horsepower motors.

New Activated Carbon finds e x t e n s i v e u s e ! A new grade of "Columbia" activated carbon for use as a catalyst support material has been developed by National Carbon Company. Combining high activity, strength and porosity, the new grade CXC 4 / 6 is priced at half that of the wellknown grade C X A L 4 / 6 it replaces. Grade C X C 4 / 6 is expected to give better performance than previous grades in a wide variety of additional uses. It is available in the form of 3 / 1 6 " diameter pellets.

the abuse normally encountered in this type of service. However, when changing the seal, the steel support casting was damaged. The body bolts were tightened so hard that the pressure broke the casting. The "Karbate" volute case and cover were not even chipped. Here is proof that "Karbate" impervious graphite pumps are built to "take it" and that the armored design minimizes the possibility of damage even under the most severe operating and poorest maintenance conditions.
