This is a Salient Characteristic Checklist used for evaluating vendor proposals against government minimum requirements for equipment procurement.

The solicitation requires two volumetric dry screw feeders (Series 32-055) for feeding soda ash at a rate of 5-10 lbs per hour. Each feeder unit must include a 1-1/2" stainless steel feed screw and discharge spout designed for granular service, a low-speed gearbox with 0.60 cu. ft./hr. maximum feed rate and 4-speed drive pulley, a 1/6 cu. ft. stainless steel inlet hopper with agitation and cover, and a 1/6 HP permanent magnet DC motor (TENV rated). The control unit must be LoL-mounted NEMA 12 configuration with power on/off switch, motor remote-local stop switch, auto-manual switch, auto dosage potentiometer, and digital feed display with adjustment capabilities. The procurement also includes a 35-gallon rectangular stainless steel solution mixing tank with cover, mounting hardware for the feeder installation on the tank cover, an included dust arrestor with water line and spray nozzle, and a mechanical mixer featuring a 1/4 HP motor (115/230 VAC, TENV rated) with jet agitator. The checklist provides columns for vendor proposed specifications, government verification (Pass/Fail), and evaluator comments, with an evaluator certification statement affirming that the evaluation was conducted fairly and impartially based solely on established solicitation criteria.
