13 Common Factors that Affect Pump Life | Pumps & Systems
13 Common Factors that Affect Pump Life | Pumps & Systems

Fluid properties (the fluid’s personality) such as pH, viscosity and specific gravity are key factors. If the fluid is acidic or caustic, the pump wetted parts such as the casing and impeller materials need to hold up in service. The amount of solids present in the fluid and their ,size,, shape and abrasive qualities will all be factors. 7. Service
