The main characteristics of the pumped fluid to be known for a correct pump selection are:
The nature and the temperature of the medium influence the selection of the pump material. In fact, each material has a different mechanical / chemical compatibility with the pumped fluid and at the same time has a resistance to the operating temperature. Therefore, knowing the type of fluid, its concentration and its temperature allow the correct selection of compatible materials.
The density and viscosity of the fluid affect the power of the motor to be selected and at the same time the correct sizing of the impeller trim, to ensure the required performance is achieved.
The presence of solid suspensions in the pumped liquid: this information is important for the choice of the type of centrifugal pump to be selected.
