A common mining industry misconception is that the only way to achieve a reliable seal on tough pumping applications is by using gland packing. Unfortunately, gland packing goes hand in hand with high water consumption, high maintenance costs, poor availability of equipment and large production losses. As a result, mechanical seals were introduced to mines a few decades ago. However, end-users were not adequately trained and, for years, have been supplied with the incorrect type of seals, poor choice of materials, and wrong - or, in some cases, no - seal support systems. This contributed to the general misconception that mechanical seals do not work in the mining industry.
