Feed hypochlorite solution in direct proportion to waterflow rate.
Chlorinates waterflow rate from 2 to 350 gallons per minute.
Uses water pressure as power source.
1-10. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS. See figure 1-2.
a. Four-Inch Manifold (1). A 4-inch diameter pipe for connection to a water supply line. The manifold
provides lateral outlets to power the solution feed pump and permit hypochlorite solution injection to the water-
b. Range Adjusting Valve (2). Mounted in the manifold and used to bypass enough waterflow through
the water meter to operate the solution feed pump.
c. Flow Controller (3). A mechanical flowmeter modified with a gear box and a control pilot valve to
operate the solution feed pump.
d. Solution Feed Pump (4). A hydraulically operated positive displacement proportioning pump.
e. Reservoir Tank (5). A 6-gallon plastic tank holding the hypochlorite and water solution.
