What happens when a pump's mechanical seal fails?

When a pump's mechanical seal fails, the primary consequence is that leakage may occur. The mechanical seal is a critical component designed to prevent fluid from escaping the pump's housing and to maintain proper pressure within the system. When it fails, this seal no longer confines the liquid, which can lead to significant leakage from the pump. This leakage can compromise the efficiency and functionality of the entire pumping system, potentially leading to the need for repairs or replacement of components.

While mechanical seal failure can affect pump pressure and efficiency, leakage is the most immediate and noticeable result. It typically indicates that the seal is unable to contain the fluid, allowing it to escape. Managing this leakage is crucial for maintaining operational integrity and preventing further damage to the pump or surrounding equipment.
