ABSTRACT:
A mechanical seal construction of the double or tandem-type, wherein a stationary ring, preferably the gland ring, is provided with a circulation inducing dam positioned within an annular chamber defined between the inner and outer seals. The dam extends from the downstream side of an outlet to the upstream side of an inlet, whereby rotation of the shaft effectively induces coolant to flow into the chamber through the inlet and then around the chamber to the outlet. The dam has end walls which effectively act as deflectors at both the inlet and outlet to assist the cooling fluid in its entry into and departure from the chamber.
