The stupendousness of this war has upset old senses of proportion and dwarfed former scales of operation in most every kind of enterprise.

The 5000-barrel petroleum refining unit — a sizable j ob only a few years ago — finds itself a Lilliputian among today’s 60,000-barrel to 90,000-barrel Gullivers. Synthetic rubber production has risen from an experimental play­

thing to a giant industry. Plants and units in the chemical processing industries are decisively bigger.

Setting up these large-scale manufacturing facilities has naturally required “ bigger” thinking. Plans, process engi­

neering, design, and the application of new methods involve entirely new considerations.

No longer, in looking toward expansion, can the average operator’s engineering department be expected to possess all the desirable background to undertake alone the job of important new plant construction or modernization. For no matter how large or small the plant, its pattern must embody the means for meeting the competition of the modern war-built giant.

The Badger organization has headed so many large wartime engineering and construction jobs in the chemical, petro-chemical and petroleum refining industries that Badger thinking can almost certainly be of great help to you — (a) in an advisory capacity, (b) as co-managers with your own engineering and executive departments, or (c) under sole responsibility for putting through the entire project from preliminary plan to practical operating stage.

Badger engineering services include:

Analysis and Evaluation of Processing Requirements.

Selection and Design of Processing Methods.

Estimating Costs of Equipment, Materials, and Entire Projects.

Determining Utility Services and Operating Requirements.

Summary of Costs and Economics of Projects.

Design, Manufacture, and Selection of Equipment.

Procurement and Expediting of Materials.

Supervision of Erection and Complete Field Construction.

Test-Operation to Demonstrate Design Performance.

Planning, Development, and Improvement of Processes.

CHEMICAL STONEWARE Are you faced with the task o f specifying a pump for a difficult corrosion application? Here are some FACTS to help you.

SPECIFICATIONS: Description o f types manu­

factured and method o f construction; table of capacities and sizes; testing and installation procedure.

DRAW INGS: Dimensioned drawings of assem­

bled pumps, both belt driven and direct drive;

detail drawings showing operating parts and water cooled stuffing box.

C A P A C IT Y A N D P O W ER C O N S U M P T IO N : Graphs showing the characteristics o f

stone-If your duties involve the handling of corro­

sive liquids, this new bulletin will be a valuable adjunct to your files. General Ceramics Armored Stoneware Centrifugal Pumps offer the corro­

sion protection which is characteristic only of stoneware and also the correct mechanical de­

sign to insure efficiency, freedom from break­

dow ns, and resistance to m ech an ical abuse.

Since the "w et end” is stoneware, the liquids handled touch no metal and the pumps are admirably adapted for handling bleach solu­

tions, strong acids, pharmaceuticals, and food products.

Send us the details o f your pum ping problem and ask for bulletin N o . 211 on your letterhead.
