A metering pump is purposely designed to move fluids at highly precise flow rates over certain periods of time. This ability to deliver media with detailed accuracy is called “metering.” Because of this unique ability, many different types of pumps can be considered metering pumps. However, most metering pumps are classified as diaphragm pumps (pumps controlled by solenoid, mechanical actuation, or hydraulic actuation). Metering pumps commonly have the ability for a user to set, adjust, and program the flow rate via a hand dial, touch pad, or other form of control.
