% INTAKE PUMPS Intake pumps consist of six peerless deep well turbine pumps* powered by 400 HPS 4150 volt General Electric motors* Pump columns are 13 inches O.D. with flanged joints, and measure 196 feet inches from motor base to bottom of strainers. Pumps are set in two rows of three, and each three discharge through $ 16 inch pipesto a 28 inch manifold. The two discharge manifolds connect to the 40 inch W.S.P* pressure main. An 3 inch Pelton Surge Suppressor is mounted at the discharge of each pump. Motors are controlled by float switches located at the Booster Station Reservoir. 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.
