Is there anyone who can explain the working principle of a metering pump?

Also, do the inlets and outlets need to be fully open at startup? How is the concentration adjusted?
:) Metering pumps are classified into diaphragm type, mechanical type, and plunger type. I wonder what kind you use?
Used for dosing in boilers; I’m not sure what type it is
Are there any photos? ? ? ? Nameplate + body
Secondly, what concentration are you referring to? ? ? ? ? It is impossible for a metering pump to adjust the concentration of the chemical added. The chemicals can only be added according to the parameters you set.
Agree with the opinion above. Additionally, we use DePam metering pumps, which are of really good quality; very few of them break.
We’re not allowed to bring phones to the company site, so we can’t take photos
Is that so? I see a knob on the pump body with a scale from 0 to 100 that can be adjusted
The optimal operating condition for a metering pump is when the scale reading is between 60 and 80.
