Read the following passage:
Hydraulic pumps in heavy engineering machinery require a steady flow of fluid from the reservoir to maintain operational pressure. When intake lines become partially obstructed by debris or when fluid viscosity is excessively high during cold-weather startups, the intake pressure can drop below the vapor pressure of the hydraulic oil. This pressure drop causes localized vapor bubbles to form within the fluid stream. As these bubbles travel into the higher-pressure discharge zones of the pump, they rapidly collapse. The resulting micro-jets of fluid strike internal metal surfaces with high force, causing metal pitting and accelerated mechanical wear.
Statement: Based on the passage, mechanical wear from vapor bubble collapse can develop in a hydraulic pump even if the intake lines are entirely free of physical debris.
