ABSTRACT:
The seal assembly comprises a housing, a shaft, seals, and a reservoir. The housing has a hollow section bounded by a cylindrical surface and a first curved protrusion. The housing has a first channel and a second channel extending from the hollow section. The shaft extends through the hollow section. Seals seal the hollow section with respect to the shaft to form a chamber. The combination of the first curved protrusion and the sleeve cooperatively form a hydraulic pump for conveying a lubricating fluid from the chamber via the first channel to reservoir. The lubricating fluid is circulated from the reservoir to the chamber via a second channel. The seal assembly has a fluid level gauge or an optoelectronic leak detector for detecting leaks in the seals of the seal assembly or leaks in a fluid pump (i.e. a magnetic-drive centrifugal pump) coupled to the seal assembly.
