Inadequate pulsation control and poor valve performance, along with faulty mechanical piping design, are the primary causes of excessive vibration in positive displacement (PD) pump systems. Therefore, a working knowledge of how pulsation and valve dynamics influence PD pump vibration is essential for the design and operation of safe and reliable systems.
