The video shows a leaking mechanical seal. When this happens it can spark many other problems in its wake. The pressurized fluid can often enter the bearing housing causing the lubricating oil to emulsify (looks like mayonnaise) which leads to bearing failure and coupling and/or possibly motor damage. Correct leaking seals as soon as they are discovered because further issues can result. The mechanical seal plays a very important job in the life of a pump and should never be ignored or considered an afterthought.
