They are recommended for contractor's, agricultural and in dustrial uses as most reliable small pumps. Cap. from 1 in. pipe, 10 ft. lid., 5 g. p. m. up. sary. De Laval ve locity stage turbines built in all sizes up to 1200 hp. CENTRIFUGAL BLOWERS AND COMPRESSORS: De Laval Centrifugal blowers and compres Type F Centrifugal Pump Arranged for Belt Drive De Laval Pressure sors arebuilt single stage Stage Turbines, built and multistage, and in capacities up to for motor or turbine 15,000 hp., give the drive, for all pressures highest obtainable up to 100 lbs. per efficiencies. The sq. in. compound geared turbine realizes the highest efficiencies with high pressure superheated steam and high vac uum and is unexcelled for driving direct current generators, centrif ugal pumps, ship propellers, etc. Single Stage Pump FLEXIBLE COUPLINGS: De Laval rubber bushing flexible coup Turbine Driven Blast Furnace Blower, 60,000 lings have been devel Cu.

Stocked 13*6-12 in.; others to order. De Laval Centrifugal Pumps are characterized by conservative speeds, high class materials, con struction on a limit-gage inter changeable basis, guaranteed effi ciency and capacity and a com prehensive system of testing. The WATER TURBINES: Small and medium capacities. For driving auxiliaries in water works pumping stations they are more economical than electric motors or small steam turbines. From 1 to 200 hp. GUARANTEES: Flexible Coupling low starting torque, self-limiting power characteristic and high effi ciency of De Laval centrifugal pumps adapt them to be driven by electric motors, including selfstarting synchronous motors. Four Geared Steam Turbine Driven Centrifugal Pumping Units 75,000,000 Gal. per Day Each Against 150 Ft. Head All De Laval apparatus is built on a limit gage, interchangeable basis. Finished repair parts are supplied, made to accurate di mensions, so that they can be installed in the machine without requiring to be fitted. The performance of every machine is guaranteed, both as to capacity and efficiency, and a complete test is carried out before shipment. {See page 324 for additional Products of this Company) Mechanical Catalog Consisting of uniformly presented and illustrated catalog information, conveniently classified, describing the products of manufacturers of mechanical equipment \vith DIRECTORY OF MANUFACTURERS OF INDUSTRIAL EQUIPMENT, MATERIALS AND SUPPLIES A specialized, classified and cross-indexed list. with names and addresses inserted free of charge 1930-31 TWENTIETH ANNUAL VOLUME ISSUED OCTOBER 1930 .Published By I THE AMERICAN SOCIETY OF MECHANICAL ENGINEERS 29 WEST 39th STREET, NEW YORK, N.
