FPM

FEET PER MINUTE (fpm.) F001

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 (25 meters/sec). At speeds above this number you should purchase stationary seal designs.
