Model ZLR-1205 Concentric Double Mechanical Seal Manual

Congratulations on your purchase of the most advanced sealing technology available today making your pumps and other rotating equipment safer, more reliable and longer running. Your new concentric double seal provides all the advantages of stationary design, double balance, and easy cartridge mounting as well as the ability to later be upgraded to a full tri-plex design (model ZLR-1310) which provides two separate fluid barriers between your process and the environment. If one seal fails, the second automatically takes over. This “installed spare” provides double the protecion, double the safety, and virtually zero emissions.
