In What Condition Does The Metering Pump Use Self - Fill Suction?

The metering pump can be used in the following situations:

1. The measured liquid is volatile;

2. Large proportion of liquid weighing;

3. When high stroke frequency is required;

4. The metering pump works at high altitudes;

5. Large storage tanks are required for on-site application, and it is dependent on the measurement pump's self-absorption.

Let me share with you some Suggestions on the selection of the metering pump.

When it comes to the corrosion of the pump head/seal, what are the problems and how to avoid them?

When it comes to metering pump heads, the usual problem is the presence of acid, chlorine, fluoride, and hydrogen peroxide. It is difficult to determine the specific pump head material due to the different concentration of drugs and operating temperature. When measuring fluoride, we recommend Viton? Sealed PVC pump head. For most applications of chlorination, it is preferable to choose an EPDM sealed NP(plexiglass) pump head. The metering of hydrogen peroxide mixtures can only be PTFE sealed PTFE pump head or stainless steel pump head. The measurement of concentrated hydrochloric acid is usually Viton? Sealed plexiglass pump head. The metering of concentrated sulfuric acid can be selected by PTFE sealed PTFE pump head.
