What is chemical dosing pump?

Dosing pump is a volumetric chemical dosing system that can change capacity manually or automatically as required by process conditions. About 90% of all pumps sold are transfer pumps, used to move liquids from point a to point b. Metering pumps are designed for the precise injection of chemicals, acids, bases, corrosive or viscous liquids and slurries. Metering pumps are needed for applications where one or more conditions exist:

  • Requires high precision feed rate
  • Requires low flow rate (ml/hr or GPH)
  • High system pressure
  • Variable flow rate, must be controlled by computer, microprocessor, DCS or PLC
  • Handles corrosive, dangerous or high temperature fluids
  • Requires pumping of viscous fluids or slurries

Where are metering pumps used?

There are thousands of applications requiring corrosion inhibitors, wax inhibitors, biocides, antifreeze, disinfectants, coagulants, oxygen scavengers, polymers, softeners, acids/bases, process additives and other types of chemicals. The main industries where metering pumps are purchased are:

  • Industrial water treatment (cooling towers, boilers)
  • Drinking water and wastewater treatment
  • Oil and gas production
  • Chemical and petrochemical processing industry
  • Power generation
  • Agriculture
  • Manufacturing
  • Food and Beverage Production
