The TYPE 82 and TYPE 84 are BIDIRECTIONAL mechanical seals and are therefore unaffected by the direction of shaft rotation. The drive is positively made by screws, which lock onto the shaft; the spring only has the function of holding the seal faces in contact. The materials employed and the applications are similar to those of TYPE 2 for TYPE 82 and of TYPE 4 for TYPE 84. These seals have a limited axial length and compact shape for
fitting well into reduced spaces.
