What does continuous leakage from a mechanical seal on a pump indicate?

The pump is not properly aligned
The mechanical seal needs to be replaced
There is too much pressure in the system
The pump is overworked

The correct answer is: The mechanical seal needs to be replaced

Continuous leakage from a mechanical seal on a pump typically indicates that the mechanical seal has deteriorated or failed, necessitating its replacement. Mechanical seals are designed to create a tight seal to prevent fluids from leaking out; when they begin to leak continuously, it suggests that the sealing surfaces are worn, damaged, or compromised in some way. This could occur due to various factors such as improper installation, excessive wear over time, or a failure related to operating conditions. Understanding this is crucial for maintaining the operational integrity and efficiency of a pump system. If the seal is not replaced promptly, it could lead to more significant issues, including pump damage or system failure, which could result in costly repairs and downtime. Therefore, recognizing continuous leakage as a sign that the mechanical seal needs attention is key to effective pump maintenance and operation.
