Peristaltic Pump

The S128 Medicator is a peristaltic metering pump designed to deliver at a ratio of 1:128; 1 ounce of product into a gallon of process water. The primary application is for injection of solutions commonly used in livestock production, particularly chicken, turkey, ducks and swine.
