What pump should be used for this operating condition?
Thread Content
15% sulfuric acid, temperature 95 degrees Celsius, flow rate 11 cubic meters per hour, pressure 3.5 MPa; measurement is required. What material should be used for the pump? I’m going crazy! ! ! Some companies recommend diaphragm metering pumps, but they are expensive! A company recommended a plunger pump, but there is leakage at the packing area! How to choose! ! ! Has anyone used it under the same working conditions? I’d like to ask the experts here.
This condition shouldn’t be hard to meet – just search online for the top 10 manufacturers, pick a few at random, and ask them for information
I would also appreciate it if the experts here could offer some advice. It couldn’t be found; the pressure of Chen’s tetrafluoro compound is not sufficient.
Metering pumps are completely fine, and their price isn’t very high either.

Diaphragm pump, but the pump head needs to be made of alloy 20~~
For alloy 20, we conducted hanging sheet tests. Corrosion over one week: 0.0012g. What are the operating conditions used upstairs?
