Selecting the right pump involves considering several factors, including the fluid being pumped, flow and head conditions, site constraints, and total life-cycle costs. The document discusses 8 groups of factors to consider: 1) solids content, 2) suitability to purpose, 3) flexibility, 4) maintainability, 5) wearing concerns, 6) system curves, 7) systemic questions, and 8) total system efficiency over the life of the pump. Total system efficiency considers hydraulic efficiency, maintenance efficiency, durability, and backup operations. Examples of different pumping applications are also provided.
