Abstract
The disclosure illustrates an anti rotation seal assembly for use with a shaft mounted impeller or other rotatable element having a wear face. A nose portion of a carbon sealing washer is urged against the wear face by a spring contained within a non rotatable seal housing. The sealing washer has surfaces on its outer periphery which engage anti rotation elements supported by the seal housing to prevent rotation of the washer while permitting axial movement. In another form the anti rotation elements may be molded into the washer.
