Type 7828, 7848
Type 7800 Series is a modular, dualpressurized, back-to-back, O-ring pusher cartridge seal designed for mixer applications. Compact standard versions, including a bearing option, are available from 1 to 8 inches. Type 7848 is available as a liquid-lubricated or contacting dry-running version, whereas Type 7828 is a non-contacting gaslubricated design for high-purity applications. Where reduced barrier gas consumption is desirable, Type 7828GD is a hybrid design that offers a combination of non-contacting dry-running seal faces inboard and contacting dry running seal faces outboard.
