How should I choose the model and materials for this pump, and how do I go about purchasing it? It’s really troubling

How should I select the model and material for the pump below, and how do I go about purchasing it? It’s a hassle; maybe metering capabilities are required
The flow rate is too high; a metering pump cannot be used, and a centrifugal pump should be chosen instead. A flow control circuit is installed at the pump outlet to regulate the flow rate.
Another question is: what are the properties of this medium?
It is also necessary to understand the corrosion properties of the materials. As a catalyst dosing pump, it is recommended to use a plunger diaphragm pump, as it provides greater reliability. Milton Roy and Degauss – I’ve used both, and the quality is fine. For specific questions, you can consult the manufacturer
Are there diaphragm pumps with such a high flow rate (500 m3/h)?
Tri-n-butylamine is a colorless to pale yellow liquid. It has a special smell. It absorbs moisture easily. It has a weakly alkaline nature; pay attention to alkaline corrosion when selecting the pump
Flow accumulation is provided at the pump outlet, which can be used for measurement
Do metering pumps come in such a high flow rate? It is recommended to use the ZA pump model ZA200-250B (2950 RPM, NPSHR 6.5 m, EFF 78%, 90 KW), or ZA250-400 (1475 RPM, NPSHR 2.8 m, EFF 73%, 90 KW). Carbon steel can be used for the material; I found information on tributylamine – no data was available for tri-n-butylamine, but it should be the same. If those options are not suitable, then a double-suction pump would have to be considered. It is not possible to achieve the functionality of a metering pump with these pumps
Indeed, the traffic volume is too high; I didn’t notice it at first and thought there was an error in the data entry: L (Why is such a large amount of catalyst used?) ? ? ), upon consultation with Milton Roy, the maximum flow rate of their metering pumps is several dozen cubic meters per hour. It cannot meet the requirements.
Is the unit for traffic data wrong? Could it be cubic centimeters per hour?
