Design Fundamentals

Contacting Liquid Lubricated Seals The basic components of a mechanical seal are the primary and mating rings. Together they form the dynamic sealing surfaces, which are perpendicular to the shaft. The primary ring is part of the seal head assembly, while the mating ring and static seal form a second assembly, making a complete installation for a pump. These basic seal parts are shown in Figure 3. For slower and normal shaft speeds, the seal head assembly will rotate with the shaft, while on high shaft speeds, the seal head assembly will be held stationary to the equipment.

The only difference between contacting and non-contacting seal technologies is found in the design of the seal faces. Each system has the same type and number of parts. Each has its own area of application for maximum sealing efficiency. Non-contacting seal technology will be discussed later.
