Automatic Metering Screw Feed System for Mixing and Dispensing Dry Polymers into A Secondary Process

The Model VMF-90F Volumetric Screw Feeder with Wetting Cone has been designed to be an “all in one” skid package option for adding an in-line dry chemical addition process. The VMF-90F is capable of accurately dispensing many common chemicals found in the water and waste water industries, as well as, a host of other industrial chemicals directly into a supply line. The VMF-90F is the perfect choice when you need to control the addition of small to medium doses of dry chemicals to a process. To meet customer demands Scaletron has combined a rugged screw feeder, vibratory agitator, programmable control module, a number of standard upgrades, a wetting cone and an eductor and then mounted it all to a base that will fit through almost any normal size doorway. If you are looking to do a “one and done install” for a dry chemical feeding system, then Scaletron is sure the VMF-90F will meet and exceed your chemical feeding needs.
