What is a consequence of improperly positioned shaft seals?

Improperly positioned shaft seals lead to water leakage along the shaft. Shaft seals are designed to prevent fluids from escaping the machine, typically around rotating shafts like those found in pumps. When these seals are not correctly installed or positioned, they may not create an effective barrier, resulting in water and other fluids leaking out from the system. This leakage can compromise the efficiency of the equipment, lead to operational issues, and create maintenance challenges over time.

In contrast, the other options suggest outcomes that would not typically result from poorly positioned shaft seals. Increased water pressure, enhanced impeller performance, and reduced energy consumption are all associated with well-functioning equipment. However, the leakage from improperly positioned seals would likely cause increased operational costs and decrease overall system performance, not enhance it.
