CarLife^® 99PR is a high-flow circulation pump seal designed specifically for high-temperature processes exceeding 80℃. When equipped with a dedicated heat exchanger (WCHE) and a throat bushing on the process side, and utilizing the API Piping Plan23, it provides superior heat dissipation. 

CarLife^® 99PR is the ideal sealing solution for boiler feed water pumps (BFW Pump) and is commonly employed in high-temperature or volatile processes such as hot water, thermal oil, and chemical solvents, including applications in power plants.
