Hydraulic leaks pose significant challenges in various industries. Understanding the types of hydraulic leaks is crucial for effective maintenance. Common types include external leaks, internal leaks, and case drain leaks. External leaks are visible and occur at hose connections, while internal leaks can compromise system performance. Case drain leaks involve fluid escaping through the pump's case drain line. Identifying and addressing these issues promptly is essential for preventing equipment damage and ensuring smooth operations.
