Abstract
A mechanical seal for providing a fluid-tight seal between relatively rotatable elements includes a stationary part for securing to a housing, which has a stationary seal face, a rotary part for securing to a shaft, which includes a rotary seal face, a spring urging the rotary seal face into engagement with the stationary seal face and a toroidal sealing member between the rotary component and the shaft. The toroidal sealing member is accommodated within a recess of the rotary part, and the recess is defined by two members of which the first rotary part member includes the seal face and a second rotary part member is positioned between the first rotary part member and the spring.
