1. A mechanical seal, comprising:
a longitudinally floating first member having a seal face;
a longitudinally non-floating second member;
a longitudinally floating third member;
an elastomeric member being in sealing engagement with said longitudinally floating first member, said longitudinally non-floating second member and said longitudinally floating third member, said longitudinally non-floating second member extending along a shaft member and squeezing said elastomeric member into engagement with the shaft member and further having an outer surface with a groove therein for allowing an inwardly protruding portion of said elastomeric member to engage therewith, said elastomeric member having a profile comprising at least one convolution for allowing said longitudinally floating first member and said longitudinally floating third member to move in an axial direction, wherein said at least one convolution extends outwardly when said longitudinally floating first member and said longitudinally floating third member move toward said longitudinally non-floating second member, said at least one convolution permitting a radial distortion of said elastomeric member during installation; and,
spring biasing means longitudinally positioned between said longitudinally floating first member and said longitudinally non-floating second member, with one of said longitudinally floating first member and said longitudinally non-floating second member having a protruding male portion and said longitudinally floating first member and said longitudinally non-floating second member not having said protruding male portion instead having a corresponding female portion into which said protruding male portion locates.
