ABSTRACT:
A split mechanical seal incorporating a spring retainer is disclosed. The mechanical seal of the present invention is constructed to prevent fluid leakages from equipment having a fixed cavity, containing the fluid, and a rotatable shaft. The spring retainer of the invention includes an annular plate which receives and holds a spring in the correct position inside of a seal housing and a radially projecting member associated with the annular plate. Movement of the retainer under the action of the retained spring is stopped by the projecting member abutting an appropriately positioned projecting element on the inside of the seal housing, before the spring is fully extended. This feature prevents the spring from fully extending and, thus, retains it in position between the retainer and the internal wall of the seal housing.
