Matching Pump Type Selection with Medium Characteristics
Selecting the appropriate pump type requires consideration of various characteristics of the medium. Viscosity is a key parameter; for instance, screw pumps demonstrate higher efficiency when handling high-viscosity fluids. The lubricity of the medium affects the wear rate of internal pump components. Chemical corrosiveness determines the choice of pump casing material and sealing materials. Furthermore, whether the medium contains gas or solid particles, and the size of those particles, are factors that need evaluation when selecting a pump type (e.g., single screw pumps are suitable for media containing particles).
