Designed as a low cost pump with improved chemical resistance for chemical feeding, transfer, circulation, filtration, metering, filling line use and similar applications. Handles pure solutions, foaming liquids, and thin emulsions. Because of the chemical, resistance of phenolic plastic and 316 stainless steel, these pumps are widely used to pump photo chemicals, plating solutions, lab solutions, pharmaceuticals, cosmetics, weak acids, alkalies, liquid fertilizers, insecticides, dyes, detergents, waxes and many more. Limit to liquids with viscosity less than 50 SSU.
