Economical Automatic Metering Screw Feed System for Mixing and Dispensing Dry Polymers into A Secondary Process
The Model VMF-90C Volumetric Screw Feeder has been designed to be a “stand alone” option for adding a simple volumetric feeding unit to any process. The VMF-90C 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. The VMF-90C is the perfect choice for an economical, basic feeder while still incorporating a few standard industry upgrades like a concentric material conditioning auger, SCR motor controller and a vibratory agitator mount.
