Mechanical face seals. A rotating mechanical face seal is generally located at the top of each protection chamber. A typical design is shown in Fig. 6. The rotating part of the face seal is sealed to the shaft by elastomeric bellows. The stationary part is sealed into the stationary component of the seal-chamber section.
Rotating equipment often requires a dynamic mechanical seal to create a seal between a rotating shaft and a stationary body and prevent the escape of process fluid(s) including liquid and/or gas. They can also be used in mixer seals to prevent fugitive ambient particulates from entering a contained vessel being mixed such as a pharmaceutical reaction vessel.

O'ring Groove Design. As important as the o'ring seal itself is the groove that the o'ring seats into. The groove must be designed to accommodate not just the o'ring size, but also its intended usage; be it dynamic or static operation, radial or axial loading, vacuum or high pressure.
Mechanical seals according to EN 12756 (code system) For single mechanical seals there is a distinction drawn between standard (N) and short (K) types. For double mechanical seals (back-to-back) EN specifies the short type only. Symbols A Area of sliding face A H Area hydraulically loaded by medium pressure b Width of sliding face

An alternative design is an all-rubber seal. Rubber seals address the corrosion issues but lack the rigidity of a metal encased seal. Mechanical face seals were originally used in the automotive industry for engine coolants. Now mechanical face seals are used in the chemical, petrochemical, and utility industries.

A few basic components and principles in mechanical seal design contribute to a working seal at the interface of the rotating shaft and stationary pump/mixer/seal-chamber housing. Mechanical seals are usually end-face seals or rotating-face seals, but in some designs they can be circumferential or even a hybrid of lip-type seals.
The mechanical seal Mechanical seals have the purpose of preventing leakage of a fluid (liquid or gaseous) through the clearance between a shaft and the fluid container. (Fig.1) The main components of a mechanical seal are the seal rings on which a mechanical force is acting, generated by springs or

Mechanical seals are typically used for pressures up to 1000 psi. They have the added feature of providing more positive sealing during shutdown. They rely on the continuous contact between a rotating and fixed seat that are separated by a carbon ring (refer to Fig. 8.44).Sealing is accomplished by vertical contact between the carbon ring and the rotating and …
Lip seals are generally only good up to 25 PSI, while shaft seals for pumps (face type mechanical seals) are rated for a minimum of 200 PSI. Lip type shaft seals take up very little space, while pump shaft seals require a rotating head, a stationary and an energizer (a single spring, multiple spring or metal bellows).
