Chemical Metering


Chemical Metering Pumps

Chemical metering pumps, also known as dosing pumps, are used to accurately and consistently inject chemicals into a process stream at a predetermined rate. These pumps are commonly used in various industries, including water treatment, chemical processing, food and beverage, pharmaceuticals, and agriculture.

Chemical metering pumps can be used in the following ways:

  • Water treatment: Chemical metering pumps are used to inject chemicals such as chlorine, sodium hypochlorite, and other disinfectants into water treatment processes.
  • Chemical processing: Chemical metering pumps are used to add precise amounts of chemicals to chemical processes, including catalysts, acids, and bases.
  • Food and beverage: Chemical metering pumps are used in food and beverage processing to accurately dose ingredients such as flavorings, preservatives, and sanitizers.
  • Pharmaceuticals: Chemical metering pumps are used in pharmaceutical production to accurately dose active ingredients, buffers, and other chemicals.
  • Agriculture: Chemical metering pumps are used in agriculture to apply precise amounts of fertilizers, herbicides, and pesticides.

In general, chemical metering pumps are used wherever accurate and consistent dosing of chemicals is required.
