What may happen if the discharge flow volume is increased excessively when operating from a pressurized water source?

When the discharge flow volume is increased excessively while operating from a pressurized water source, it can lead to cavitation of the pump. Cavitation occurs when the pressure at the pump’s inlet drops below the vapor pressure of the liquid being pumped, resulting in the formation of vapor bubbles. These bubbles can collapse violently as they move to higher pressure areas within the pump, causing shock waves that can damage pump components and decrease its operational efficiency.

Maintaining appropriate discharge flow is crucial to ensure that the pressure remains adequate at the pump's suction, preventing cavitation and ensuring the longevity and effectiveness of the pump. Moreover, excessive discharge flow might lead to other issues, such as potential strain on the system and loss of operational reliability, but cavitation is particularly significant due to its impact on the pump's mechanical integrity and performance.
