A dose pump, also known as a dose pump, a metering pump, is a positive displacement pump designed to inject one chemical substance or another substance into a stream of water, gas or steam. Metering pumps are usually small and provide very precise maximum flow control. They are the core part of an integrated metrology system for automation dispersion. They are pumps designed to dispense a specific amount of fluid and measure flow control. They used expansion chambers and contraction chambers to move the liquid. Over time, metering pumps have also become highly precise and can pump a wide range of liquids, including corrosive, acid and alkali, as well as mud and viscous liquids.
