What can cause increased vibration in a positive displacement pump?

Increased vibration in a positive displacement pump is commonly caused by excessive wear on internal components. As the internal parts of the pump, such as gears, rotors, or pistons, experience wear over time, they may no longer mesh or fit together properly. This misalignment or imbalance can lead to irregular movement and, consequently, increased vibration during operation.

In a positive displacement pump, the efficient transfer of fluid relies on precise interactions between its components. When these components wear down, the hydraulic efficiency is compromised, leading not just to vibration but also potential cavitation, damage, or decreased performance. Monitoring and addressing wear are crucial for maintaining optimal pump operation and preventing excessive vibration issues.
