Type 5610D/5620D

Universal Cartridge Seal Family — Wet/Dry-running Seal

The specially engineered, fully interchangeable wet/dry-running seal head extends the functionality of the 5600 product line for standard ANSI and large-bore pumps.

The exact combination of face loading and material selection incorporated into this optimized design permits operation in both wet and dry conditions.

The Type 5610D is a single cartridge using the special O-ring pusher wet/dry-running seal head.

The Type 5620D is a dual cartridge arrangement having a standard Type 5600 seal inboard and the special O-ring pusher dry-running containment seal outboard.
