Surface speed

SURFACE SPEED S109

To calculate surface speed we use the term “feet per minute” or “meters per second”. This is a better measurement of speed than rpm (revolutions per minute) because it takes into account the diameter of the piece that is rotating.

 

In the seal business the diameter is taken at the middle of the seal face. Rotating seals have a limit of 5000 feet per minute or 25 meters per second.

At speeds above this number you should purchase stationary seal designs.
