Model VMF-28 PM™ Volumetric Screw Feeder for Polymer Mixing

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

The Model VMF-28 PM Volumetric Screw Feeder for Polymer Mixing has been designed to be an “all in one” skid package option for polymer mixing and dispensing. The VMF-28 PM is capable of accurately dispensing dry polymers found in the water and waste water industries. The VMF-28 PM is the perfect choice when you need to control the addition of small to medium solution doses of polymers to a process. To meet customer demands Scaletron has combined a rugged screw feeder, programmable control module, a number of standard upgrades, two (2) aging/mixing tanks, and a progressive cavity pump 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 polymer mixing and dispensing system, then Scaletron is sure the VMF-28 PM will meet and exceed your needs.
