ABSTRACT:
A centrifugal pump system including a pump having a rotating seal disposed therein, the temperature of the seal being substantially maintained at an acceptable level by circulating a temperature stabilizing liquid to and from a chamber arranged immediately adjacent the rotating seal. A cooling or barrier tank is positioned adjacent the pump, the cooling tank for receiving the temperature stabilizing liquid from the chamber, allowing it to cool, and directing it back into the chamber thereby maintaining the temperature of the liquid adjacent the rotating seal at a substantially constant and acceptable level. A blower or fan is positioned adjacent both the pump and the cooling tank so as to simultaneously blow air across both of them in order to maintain the temperatures of the pump motor, the liquid within the cooling tank, and the rotating seal at acceptable levels.
