Challenges and Correction of Mechanical Seal Leak: Full Contact Ring
In the past, most of the pump shafts were sealed, leveraging rings of soft packing compressed by a precise packing gland. This category of shaft seal needed a fair amount of leakage to lubricate the explicit packing and make it cooler. Then came the use of mechanical seals, which confines product leakage across the pump shaft with two extremely flat...
