xxuan.vm Intake pumps consist of six Peerless deep veil turbine pumps, covered by 400 HP. 4150 volt General Electric motors. Pump columns are 18 Inches Q.D. with flanged Joints, and measure 196 feet % Inches from motor base to bottom of strainers. Pumps are set In tvo rows of three, and each three discharge through 16 Inch pipes to a 28 Inch manifold. The tvo discharge manifolds oonneot to the 40 inch W.S.P. pressure main. An 8 Inch Pelton Surge Suppressor is mounted at the dlsoharge of each pump* Motors are controlled by float switches located at the Booster Station Reseryoir. the discharge capacity of the intake pumps will vary in accordance with the lake level, and can operate between the following maximum and minimum ranges. 1 of Pumps atlng Lake Level at SLev. 1050,00 Lake Level at Slav. 1229.00 1 2 4,120 8,180 gg* 5,500 10,950 ®S" 3 12,040 • 16,320 w 4 15,5?0 n 21,480 e 5 19,040 0 26,380 B 0 22,100 0 31,010 » these tvo elevations represent the highest possible and lowest probable elevations of the lake surface.
