Considerations for Designing Piping Adjacent to a

The most disturbing flow patterns to a pump are those that result from swirling liquid that has traversed several directions in various planes. This swirl could adversely affect the pump by reducing the performance and net positive suction head (NPSH) available. It could also generate noise, vibration and damage in highsuctionenergy pumps.
