M r . B r u g m a n n was graduated from P u r d u e University with a B.S. Degree in Chemical Engineering. F o r three years h e worked in the midwest as a process engineer with a large chemical c o m p a n y . His work cov ered development of new chemical proc esses a n d the improvement of existing processes, both from t h e technical a n d economical aspects of the process. It was necessary for Brugmann t o know the r e quired equipment thoroughly, t o work on the design of new equipment a n d t o draft an economic evaluation of any changes. Mr. B r u g m a n n has been with National C a r b o n C o m p a n y since 1954. His first t w o years were spent in the Cleveland Office working u p Engineering Proposals on in coming inquiries from chemical and allied industries. H e h a s been a field engineer covering the west coast since 1956. Call y o u r National C a r b o n 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 a r e : 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 , m o n o c h l o r a c e t i c
acid, D D T ; 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 MAINTENANCE COSTS A rayon manufacturer reports us ing " K a r b a t e " 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. • • •
