"KARBATE" PUMPS HANDLE A WIDE RANGE OF CORROSIVE SERVICES EFFICIENTLY AND ECONOMICALLY
L. E. BRUGMANN, SALES ENGINEER
Mr. Brugmann was graduated from Purdue University with a B.S. Degree in Chemical Engineering. For three years he worked in the midwest as a process engineer with a large chemical company. His work cov ered development of new chemical proc esses and the improvement of existing processes, both from the technical and economical aspects of the process. It was necessary for Brugmann to know the re quired equipment thoroughly, to work on the design of new equipment and to draft an economic evaluation of any changes. Mr. Brugmann has been with National Carbon Company since 1954. His first two years were spent in the Cleveland Office working up Engineering Proposals on in coming inquiries from chemical and allied industries. He has been a field engineer covering the west coast since 1956. Call your National Carbon Sales Engineer today.
This carload of "Karbate" pumps was shipped to a major rayon producer. During the past twenty years, "Karbate" impervious graphite pumps have gained an envious performance record corro sion wise. A recent survey on service applications indicates these pumps han dle a wide variety of corrosives over a wide temperature range. Some of these solutions are: hydrochloric acid, all concentrations; phosphoric acid — up to 7 5 % ; sulphuric acid from 1 to 9 3 % ; chlorinated hydrocarbons such as ben zene h e x a c h l o r i d e , monochloracetic
acid, DDT; mixed acids such as nitrichydrofluoric, sulphuric-hydrofluoric, hydrofluoric-chromic oxide, chromicnitric hydrofluoric, phosphoric-hydro chloric nitric; chlorinated sodium and potassium chloride brines, ferric chlo ride; caustic; chlorine saturated water. The excellent corrosion resistance of "Karbate" pumps permits a given plant to utilize one type pump for all corro sive services. Such a pump standardiza tion means a saving in pump parts in ventory, and also means lower main tenance costs due to greater proficiency in handling one type pump.
"KARBATE" PUMPS FEATURE LOW M A I N T E N A N C E COSTS
A rayon manufacturer reports us ing "Karbate" impervious graphite pumps to handle rayon spin bath solutions. Maintenance costs on each pump were $25.00 the first year and $25.00 the second year — costs on an alloy pump were $25.00 the first year and $500.00 the second year. A major chlorine producer is
using "Karbate" impervious graph ite pumps to handle chlorinated cell brines. Eighteen pumps are in service. Maintenance costs on the " K a r b a t e " pumps are approxi mated at $100.00 per pump per year as compared to costs on an other non-metallic type pump of $500.00 per pump per year.
