Metering Pumps

Metering Pumps

The metering pump is a positive displacement chemical dosing device with the ability to vary capacity manually or automatically as process conditions require. It features a high level of repetitive accuracy and is capable of pumping a wide range of chemicals including acids, bases, corrosive or viscous liquids and slurries.

The pumping action is developed by a reciprocating piston which is either in direct contact with the process fluid, or is shielded from the fluid by a diaphragm. Diaphragms are actuated by hydraulic fluid between the piston and the diaphragm.

Metering pumps are generally used in applications where one or more of the following conditions exit:

  • Low flow rates in mL/hr or GPH are required
  • High system pressure exists
  • High accuracy feed rate is demanded 
  • Dosing is controlled by computer, microprocessor, DCS, PLC, or flow proportioning
  • Corrosive, hazardous, or high temperature fluids are handled
  • Viscous fluids or slurries need to be pumped
