Mechanical seals

Mechanical seal Type 140

The type 140 is a dynamic, balanced mechanical seal. The outside mounted mechanical seal is useful above all where there is little space in the stuffing box - and has the advantage that no metal comes into contact with the medium. The type 140 is an inexpensive mechanical seal for use with aggressive media.
