A removed mechanical seal that smells burnt has overheated at the faces. The smell comes from the elastomer, not the metal. Heat is generated by friction between the rotating and stationary faces once the lubricating fluid film is lost. The three usual causes are dry running, flush system failure, and installation error. A blue or rainbow tint on the carbon face signals oxidation. Diagnosis starts with the faces, then picks the elastomer by the temperature the faces actually reach, not the nameplate figure.   Read More>

Why does your mechanical seal leak? FBU SEALS explains the 7 most common causes — dry running, O-ring failure, solids scoring, misalignment, spring loss, thermal shock and wrong selection — with field signals and practical fixes. Get a free root-cause analysis.   Read More>

In industrial maintenance, your eyes and nose are the first line of defense against pump failure. This guide introduces the "sensory diagnostics" approach, teaching technicians how to interpret the colors and odors of seal leakage to identify failure modes such as thermal degradation, water ingress, and chemical permeation. Learn how to correlate sensory observations with root causes and take proactive steps to extend the MTBF of your pumping systems.   Read More>
