What are the important crriteria for pump selection for a certain application?

Type of pump

Location of pump

Fluid to pump

Head

Flow

Power requirements

Cost effectiveness

Selection of pumping equipment is a crucial point that determines both process parameters and in- use performance of the unit under development. During selection of the type of pump three groups of criteria can be distinguished:

1- Process and design requirements.

2- Nature of pumped medium.

3- Key design parameters.
