This document is a salient characteristics specification for Series 32-055 Dry Chemical Feeder Systems. The 20 CES (Civil Engineer Squadron) seeks to purchase two volumetric dry screw feeders for soda ash at a feed rate of 5-10 lbs. per hour to replace existing soda ash mixers at well 4 and well 6.

The Series 32-055 Volumetric Screw Feeder must include a 1-1/2" stainless steel feed screw and discharge spout for granular service, a low-speed gear box capable of 0.60 cu. ft./hr. maximum feed rate with 4-speed drive pully, a 1/6 cu. ft. stainless steel inlet hopper with agitation and cover, and a 1/6 HP permanent magnet DC TENV motor. The control system requires a lol-mounted NEMA 12 control unity with power on/off switch, motor remote with local stop switch, auto-manual switch, auto dosage pot, digital feed display, and adjustment capability. The Solution Mixing Tank component must include a 35-gallon rectangular stainless steel tank with cover, tank mounting part for the feeder on the stainless steel cover, a dust arrestor with water line and spray nozzle, and a mechanical mixer with 1/4 HP, 115/230 VAC, TENV motor and jet agitator.
