Let’s review the information we have so far.

1)    We have determined the duty point (flow rate and total head)

2)    We have looked at the properties of the chemical

3)    We have looked at the operating condition or environment of the application

4)    We have looked at the different types of pumps to decide which pump types we may need

5)    We have looked at different hazardous chemicals and their handling

6)    We have touched on temperature effects on S.G. and Viscosity on energy requirements

7)    We have also introduced some of the most common system configurations

Using the above information, we are ready to make the pump selection. If you have access to the manufacturer’s pump selection software, you can start with the duty point. That would provide the preliminary pump model(s) available for your application. Next, look at the pump types to narrow down your selection, e.g. if you need a seal-less pump, you may eliminate mechanical seal models. The next step will be to verify the sizing of your pump. You may require professional assistance from the manufacturer or their authorized service agents.
