Selecting the correct device is crucial to successfully handling solids. It must deal with discrete pieces that have physical size, electrical properties, frictional differences and surface characteristics that can change with the environment.
In spite of their large operating cost, most pump systems are inefficient by design. Among the common design problems are non-optimal pipe sizing, control valve utilization and, perhaps most common, incorrectly sized pumps. How a pump operates depends on the system, so improvements must focus on the system as a whole.
