Metering pump

Okay, imagine a water gun - where you press a button and water comes out. Now, imagine a tiny water gun that can only shoot tiny drops of water, and the amount of water it shoots can be changed. This tiny water gun is called a metering pump.

Basically, a metering pump is a pump that can accurately pump a specific amount of liquid. It works by using a specific mechanism (like a piston or diaphragm) to push and pull liquid into and out of the pump. The pump can be programmed to pump a specific amount of liquid, say, 1 milliliter, with each push and pull of the mechanism.

These pumps are commonly used in industries like water treatment and chemical manufacturing where precise amounts of liquid need to be added to a larger system. They can be used to add chemicals, dyes, or other liquids to mixtures to get the desired result.

So, in summary, a metering pump is a tiny pump that can accurately pump a specific amount of liquid. It's like a tiny water gun that shoots the exact amount of water you want it to shoot!
