Ettem’s “boiler feed pump seal”. This cartridge seal is specifically developed for applications where conditioning, generally cooling, of the sealed fluid by self induced, highly effective circulation is required. The self induced circulation is centrifugally driven and is independent of direction of rotation. This seal has no standard sizes, each one is application specific.   

bullet

Specifically designed for high temperature applications, such as boiler feed water pumps, where thermal management of fluid is critical.

bullet

Sealed fluid cooling is accomplished by self-induced circulation, through a heat exchanger per API plan 23.

bullet

Highly effective centrifugal pumping action, independent of direction of rotation.

bullet

Heavier solid contaminants are centrifuged away from seal faces.

bullet

Sealing surfaces of dynamic o-ring are matched for thermal expansion.

bullet

Speeds to 10,000 RPM.

bullet

Pressure to 40 bar, depending on size, sealed media, and operating conditions.
