FACE SEALS

Unlimited Uses

This is the most versatile seal. The design is simple, compact, and economical. It is easily modifiable for a wide range of applications.


TYPICAL   APPLICATIONS:

The applications are almost limitless, but range from vacuum blowers, compressors, and pumps that handle air, gases, oils, water, refrigerants, chemicals and food. 

 

MATING RINGS

The Perfect Companion

The correct mating ring design is vital to proper face seal performance. The right addition creates the ideal performance for your specific applications. After reviewing your desired application, our engineers carefully select which mating ring will best optimize your seal's performance.

Typical configurations are listed below.

TYPICAL MATING RING CONFIGURATIONS

*Customizations will be determined per your specific application*

CLAMPED RING

For all practical purposes, this design imposes no temperature, pressure, or shaft speed limitations. A shaft sleeve clamps the ring solidly to a step or bearing, providing positive drive and eliminating elastomers.
The end of the sleeve and the shaft shoulder must be square to the centerline, and their surfaces finished to approximately 125 micro in. rms.

CLAMPED RING W/ ELASTOMER

This type is also clamped in place, but it uses a static elastomer for positive sealing of low viscosity fluids. Temperatures are normally limited to 450 degrees fahrenheit, depending on the choice of elastomer.

Note: All AMS Seal clamped rings utilize equal clamping areas on either side of the ring. This eliminates any twisting moments which tend to distort the ring.

“O” rings, when used, are located in the shaft. This prevents any chance of the clamping action distorting narrow flanges on either side of the “O” ring groove.

SHAFT SHOULDER

When space is limited, a suitably finished shaft shoulder or end may act as a mating ring. This installation is not normally recommended because of the difficulty in establishing the proper surface finish, but can be implemented if desired.

BALANCED RING

This ring uses hydraulic pressure to maintain its axial location. P1 can exceed P2 by 500 psi max.

"L" SHAPED RING, PACKING DRIVEN

This is a low-cost ring for low pressure applications. It is sealed to the shaft and driven by the square packing.

SOLID RING, PIN DRIVEN

A pin provides positive drive and an “O” ring seals between the mating ring and shaft.
These rings are suitable for high reverse pressures (P2 > P1).
