The VF-100 polymer feeder from Eagle Microsystems is constructed of stainless steel and uses a direct drive to ensure optimum performance and durability in harsh chemical feed environments. It can be optimized for any dry-feed application with options like dust collectors, flex-wall agitation, explosion-proof motors, wetting cones, solution tanks, flow pacing control, extension hoppers and multiple screw and motor ranges to accommodate any required feed rate. The chemical feed rate is controlled by electronic SCR speed control for increased accuracy and control. With no external gears, pulleys, chains, belts or lubrications required, it is user-friendly and low-maintenance. 610/323-2250; www.eaglemicrosystems.com.
