Plating the Pictures for New York Newspapers Garden Photoengraving Co., Mineola, N. Y., specializes in fast, overnight service in preparing zinc plates for lithographic reprod u c t i o n s in m e t r o p o l i t a n New York newspapers. Using the Dow powderless etching process, this plant consumes an average of 40 gallons of 42° Baume* nitric acid per 2 shifts each night. Formerly, the concentrated acid was purchased in stainless steel carboys of sizes weighing 165 to 600 pounds. Handling the carboys of H N 0 3 was not only back-breaking work, but was also dangerous and costly. Mr. Leon Standley, President of Garden Photoengraving, investigated the economics and feasibility of bulk purchases of nitric acid and learned that the resulting savings in the cost of the acid would pay for the necessary safe handling system within a year's time. In fact, the refunded deposits on the stainless steel carboys paid for one of the two 1200-gallon stainless steel acid storage tanks installed just outside the etching room to receive the bulk acid by tank truck shipment. From there on, two 316 stainless steel GEARCHEM Pumps with Teflon Gears and special grease sealed lantern ring stuffing boxes, illustrated above, draw the acid
from outside storage tanks and transfer it, as needed, to the four head tanks —from which it flows to two holding tanks in cons t a n t temperature baths which maintain the acid at 70° F for subsequent safe dilution with water and organic chemicals. Then a % " GEARCHEM P u m p transfers the acid to a measuring tank where it is diluted to the proper concentrations and from which it flows by gravity to the etching machines as needed. Plates are etched in three Chemco machines, and in each machine the etchingsolution is recirculated by Eco CENTRI-CHEM Pumps installed as original equipment by Chemco Co., Glen Cove, N. Y. Thus there are six Eco pumps handling nitric acid daily for Garden Photoengraving. Pleased plant engineer Ed Klemert says of the new system, "Now Eco does the lifting." All anyone has to do to fill the head tanks is push a button. And when the plant is particularly busy at night, it is no longer necessary for the etchers to draw a pitcher or two of concentrated acid from the awkward and dangerous carboys to finish their work. Instead they, too, can simply push a button and have the Eco Pumps handle the acid for them.

Kawecki Uses GEARCHEM Pump To Fill Orders For Rare Chemicals Kawecki Chemical Co. was founded 11 years ago to produce potassium zirconium fluoride and potassium titanium fluoride used primarily to improve the properties of aluminum. Pioneering in exotic metals and their compounds, Kawecki quickly developed processing knowhow that enables it to supply bulk quantities of high purity metals and rare metal chemicals including many that were laboratory curiosities just a few years ago. Tantalum, which is used in the manufacture of capacitors and corrosion resistant equipment, now accounts for a large portion of the Kawecki sales income, but Kawecki still produces and sells many different alkali double fluorides such as potassium columbium fluoride, sodium silicofluoride,potassium tantalum fluoride, calcium titanium fluoride and ammonium zirconium fluoride to mention a few. Needing large amounts of hydrofluoric acid to process the high purity metals and to make these rare metal fluorides, Kawecki engineers ran into the usual difficult corro-
sion problems associated with handling HF solutions. Pumps transferring cold, 70 percent solutions of HF against heads to 40 feet lasted only six months at the most. But then Kawecki learned that Eco offered a GEARCHEM Pump in Hastelloy C with carbon bearings and wear plates that was highly recommended for handling HF under similar conditions existing in their Boyertown, Pa. processing plant. GEARCHEM Pumps were substituted last July, and 10 months later they show no signs of succumbing to the same fate as previous pumps. Besides good service life, the GEARCHEM Pumps have an added advantage for Kawecki for they do not require priming. Previous pump had to be primed with lubricating oil which was potentially detrimental to the high purity of the rare metals and chemicals. By installing GEARCHEM Pumps, Kawecki eliminated the contamination and corrosion problems for good.
Low Cost Flow Control Instrumentation
KIWI Takes a Shine to Eco Pumps
It has become a known fact that Eco GEARCHBM Pumps with Vickers variable speed transmissions, and equipped with Rotameters can supply highly dependable, precise and reproducible flow control instrumentation at a fraction of the cost of conventional instrumentation and expensive, custom-built metering pumps.
KIWI Shoe Polish Company of Pottstown, Pa. recently bought another Eco rotary displacement pump in stainless steel with neoprene impellers for handling abrasive titanium dioxide slurry.
Several outstanding plants are now standardizing upon this Eco-Vickers-Rotometer combination which supplies the linear, constant flow for the essential, dependable metering of a wide variety of media.
New Bulletin on Eco Pump Drives and Accessories Almost always it pays to use the drives, base plates, couplings and other accessories which have been designed especially for use with a particular pump design—because a great deal of thought and skill has been expended to make such accessories most suitable and adaptable to the various applications of the pump. And, contracted in volume or mass produced at Eco, they are generally more economical to purchase than from any other source (or to improvise in your own plant). Bulletin PD-760 describes all standard drives for All-Chem, Gearchem, Minilab and Centri-Chem Pumps—direct connected electric motor; air motor; pulley and sprocket drives; variable speed belt, hydraulic and mechanical types. It also features new channel and cast drip rim bases, precision pump mounting blocks, corrosion resistant couplings, portable pumping units, etc. Ask for your free copy.
KIWI, nationally known and highly regarded member of the spit-and-polish society of meticulous dressers, are well pleased with Eco Pump performance.
900 GEARCHEM Pumps Prove Out in Viscous Service The brawny member of the hard-to-beat GEARCHEM family, the Series 900 pump is developing an excellent reputation for handling viscous solutions. Operating at 300 rpm, a Series 900 GEARCHEM pumps a 30 percent solution of sodium lauryl sulfate with a viscosity of 5000 centipoises at 120° F. Constructed of 316 stainless steel with Hastelloy C dual spur gears and carbon bearings, this pump has l]/£ inch ports to move the thick solution at 7 gpm. This top performance is only one example of what the Series 900 GEARCHEM Pumps can do.
Providing discharge pressures to 150 psi, they will pump 1000 SSU oils at rates to 27 gpm and will handle higher viscosities to 50,000 SSU at lower capacities.
NEWS Poisonous Vapor Leaks Stopped with Eco T-Film Each month the mercury purification still at the acid plant of National Zinc Company, Inc., Bartlesville, Oklahoma is dismantled for inventory and cleaning. Formerly when the still was placed back in operation, pipefitters were beside themselves trying to seal the threaded connections to the still against the mercury vapor leaks at temperatures above 675° F. It was necessary on some occasions to remake the connections two or three times before the leaks were sealed. Then Mr. W. B. Burchfield, Pipefitter Foreman, decided to try T-FILM as a sealant even though Eco Engineering Company does not recommend this Teflon compound for temperatures above 600° F. The T-FILM worked beautifully, and the
pipefitters haven't had to remake any leaking connections since they started to use T-FILM. And speaking of T-FILM, the big stories NOT FOR PUBLICATION are the thousands of
dollars worth of this product utilized by the defense department, selected in preference to all other sealants, for certain rocketry requirements. Another interesting note is that safety engineering departments of large oxygen producers are recommending T-FILM for
liquid and gaseous oxygen systems operating at 2500 psig and over.
Remote Chemical Plant Depends on Eco GEARCHEM Arapahoe Chemicals, Inc., Boulder, Colorado uses a 400 Series GEARCHEM Pump for muriatic and sulfuric acids and occasionally a wide variety of corrosive solutions containing both strong mineral acids and powerful organic solvents. Constructed in Hastelloy C with Teflon gears, this Pump has operated quite satisfactorily for years with Arapahoe only occasionally having to buy replacement parts. This company is well known for their line of rare and specialty chemicals and synthetic compounds. The fact that Eco precision, interchangeable parts are always available, in stock, for immediate air delivery, anywhere in the United States, makes possible the confidence with which many users of Eco pumps in remote locations continue to specify them on essential services.
