Theoretical designs can be checked to secure the highest efficiencies, and to insure the satisfactory operating characteristics of the finished machine. In 1931, Dominion Engineering Works Limited built its own hydraulic laboratory, and at the same time under- took the development and test of the various designs of centrifugal and axial flow pumps and hydraulic valves. This laboratory has since been further equipped for the testing of model types of hydraulic turbines. THE progress mad Dominion Axial Flow Pum .

' flrwpunqtzo ' emand for high efficiency pumps d manufacture, Dominion Engineering Works Limited undertook in 1931 the development and testing of various de- signs of centrifugal and axial-flow pumps, concen- trating on high efiiciency pumps of special design rather than on small standard pumps for general service. The following types for which there is the greatest demand in Canada are at present manu- factured by this Company. double suction, centrifugal pumps. Generally used in water works and industrial installations, and suitable for heads up to 250;'300-ft. in the larger sizes. Single stage, single suction, non-clogging centrifugal pumps for sewage, dredge and pump service. Single stage, single suction, axial-flow pumps of high specific speed for low head appli- cations. Suitable f ' allation in large filtration plants, for drainage and irriga- tion, as a stock pump for pulp and paper mills, as a sump pump or for handling screened sewage.

HE Dominion Free Discharge Valve is an appli- cation of the needle valve form of flow control for use in waterworks mains and other large conduits using high velocity discharge. Mechanically operated, these valves are so de- signed that the hydraulic characteristics of the flow are the same at all positions of the plunger, and action is smooth and free from vibration. THE Dominion Tilting-Disc Check Valve was introduced to the Canadian market in I932. Since then, a large number of these valves have been installed in Canadian plants, and have given satisfactory service under a wide range of operating conditions. Built in sizes ranging from 4-in. to 42-in. diameters, these valves were developed to give smoothness of operation. Inherent features include: closing action with- out slamming, minimum wear of moving parts, absolute tightness over long periods of time and- very low head loss. For occasional installations where operating condi- tions are severe these valves are equipped with oil dashpots to prevent slamming. ,~ Two 6-in.

  11. 11. MANUFACTURED in Canada by Dominion Engineering Works Limited, this type of bearing is the first to make practical use of the basic principle that the bearing loads should be frried completely by the lubricating oil. The multi-tilting-pad, self-lubricating type, as indicated in diagram, includes marine thrust blocks and plummer bearings, and bearings for all types of prime movers and industrial machinery. The thrust blocks shown in the accompanying photos were manufactured for service in Cana- dian-built ships. Wartime production of these units was such that almost every ship built in Canada during this time was fitted with Dom- inion Michell Thrust Blocks.
