ABSTRACT:
The technique of the instant invention includes the preparation of a new mechanical seal life prolonger (SLP) by the compounding of a relatively few, inexpensive, and readily available materials. The instant technique is simply and easily placed into practice by, for example, applying relatively small amounts of such compound to the outside edges or peripheral portions of the relative movement interface between the seal faces of mechanical seals in association with fluid handling devices while such devices are in an operating mode. Depending on the degree of disruption of the sealing surfaces, a single application of such compound is sometimes sufficient to obtain the desired results or it may be necessary to subsequently apply such compound to the leaking seal at regular intervals subsequent to the first application thereof, until such time as it may be convenient to replace such seal faces.
