Q., Can_____1072 Beaver Hall Hill Horizontal Centrifugal (For Clear Liquids) Single-Stage Multi-Stage Horizontal Centrifugal- Pumps are gener ally used for water supply, either with overhead tanks or directly into mains as boosters. They are also used for various other services, such as boiler feeding, hot water circulation, filter swimming pool circulation. They are truly general- purpose pumps. The double-suction single-stage pumps embody up-to-date hydraulic develop ments with exceedingly high efficiencies. Their mechanical design is unusually rugged, so that they are fitted for con tinuous service. Specifications-are given in Bulletin. No. 408. The high-pressure multistage horizontal split-case pumps have one-piece bronze diaphragms which eliminate leakage be tween stages. A volute or spiral in every stage results in high-pump efficiency with out the use of diffusion vanes. The thrust is eliminated with a hydraulic balancing device.

Non-Clogging Centrifugal Pumps (For Pulpy Liquids) Made in all sizes and capacities, both horizontal and vertical, for pumping raw sewage, industrial wastes, paper pulp, food pulps, etc. They are extensively used for ejection of sub-basement drainage from buildings, in municipal sewage lift stations, and in place of conveyors in industrial plants. In addition to the pumps, we are in a position to furnish com plete sewage pumping apparatus consisting of tanks, valves, fittings, piping, electric motors, automatic control, etc., all factory assembled and ready for erection. Our engineering department is in an excellent position to assist in the layout of such equipments, whether for buildings or municipalities. Economy non clogging pumps have several important patented features which make for longer life, lower main- tainance cost.
