Does a clogged impeller affect a pump's expected rate of discharge?

A clogged impeller indeed affects a pump's expected rate of discharge. The impeller is a critical component of a pump that is responsible for moving the fluid through the system. When the impeller is clogged, its ability to efficiently create flow is compromised.

This obstruction can restrict the passage of water or fluid, leading to a decrease in the pump's efficiency and a lower discharge rate than what the pump was designed to achieve. The impact of a clogged impeller can lead to increased wear on the pump, a rise in energy consumption, and potentially can cause damage to other components of the pump system due to cavitation or overheating.

Therefore, it is essential to ensure that the impeller remains clear of debris and other blockages to maintain the expected performance of the pump.
