A metering pump is a pump that is able to flow certain liquids with a high level of precision over a period of time. It is the flow of fluid in certain levels that makes this pump often called metering. So, in other words, the metering pump is more based on its use and application.
Although basically a metering pump is used to pump water, in practice this pump is often used for other needs. Especially for the needs of the chemical and other liquids industries. Another advantage of this pump is the ability to pump fluids at high pressure.
How Does It Work?
Basically, the working principle of the metering pump is driven by the existing drive motor. Furthermore, this motor will also move the chain of teeth on the transmission box. Then, when the plunger moves backwards, the suction valve will open and suck the liquid.
However, as the plunger moves forward, the suction valve will close and the release valve will open. Thus, the fluid released by the piston can move faster and the flow becomes faster and you can adjust it as needed.
Flow At The Pump
The working principle of the metering pump is also related to the flow of the pump. The flow of this pump is usually controlled by rotation on the screw actuator by rotating it. If you open the faucet with a certain pressure, the piston will move to the pump cavity.
In this way, the performance of the metering pump is more stable and arguably superior. Especially for metering pumps that use a diaphragm system. The metering pump with the system on the other hand is also anti-leak and has a high level of security when in use. The accuracy level is also quite high, so it is very suitable for use in industry and can flow from zero level to maximum reach well.
