Where are Metering Pumps Used?


Metering pumps are specialty pumps: They’re designed for precision-injection of chemicals, acids, bases, corrosives or viscous liquids and slurries. Metering pumps are required for applications where one or more of the following conditions exist:
  • High accuracy feed rate is demanded
  • Low flow rates in ml/hr or GPH are required
  • High system pressure exists
  • Flow rates vary, and must be controlled by computer, microprocessor, DCS or PLC.
  • Corrosive, hazardous, or high temperature fluids are handled
  • Viscous fluids or slurries need to be pumped.

There are lots of applications that require corrosion inhibitors, wax inhibitors, biocides, antifreeze, disinfectants, coagulants, oxygen scavengers, polymers, softening agents, acids/bases, process additives and other types of chemicals for their processes.
The main industries that purchase metering pumps include:

  • Industrial water treatment (cooling towers and boilers)
  • Potable water & wastewater treatment
  • Oil and gas production
  • Chemical and petrochemical processing
  • Power generation
  • Agriculture
  • Manufacturing
  • Food & beverage production
