Strictly, the term “stuffing box” is related to the packed box shaft seal, long the principal device used to seal a pump’s casing where the shaft passes through it. Although the number and variety of devices used for this purpose has increased significantly as processes and the pumps used have evolved, the term stuffing box is still widely understood to mean the shaft seal, regardless of the type. For this reason, retaining the existing title of this chapter uses a familiar term to introduce a very important subject.
