ABSTRACT:
The arrangement comprises means for mounting a rotary type seal, especially a mechanical seal of the dry face type. According to an embodiment of the invention a seal mounting has a substantially circular recess in which a rotary dry face seal is received. Means (not shown) such as a key and keyway, or the like, causes a rotation of the seal mounting in common with a rotary shaft. The mounting disposes the rotary dry face seal for mechanical face sealing with a fixed seal member. The mounting recess has a circumferential inner surface which is out of round, and correspondingly the external periphery of the dry face seal is out of round, the two defining a slidable engagement therebetween. The eccentricity of the cooperating elements causes the seal mounting to engage and carry the sealing element therewith in rotation, in response to shaft rotation, obviating any need to dowel-pin the two elements together.
