The CS88B modified seal is a high-performance Mechanical Seal typically used in industrial pumps (such as those from Goulds, Flowserve, or Sulzer). While 'CS88B' is a specific manufacturer designation (often associated with brands like Flowserve or AESSEAL equivalents), it belongs to the category of Teflon bellow
The Bellows Unit (Top): The white, accordion-like section is made of PTFE (Teflon). This part provides the flexibility and spring tension needed to maintain the seal while resisting chemical attack.
The Seal Face (Dark Ring): The dark grey ring integrated into the bellows is the primary sealing face, likely made of Carbon or Silicon Carbide.
The Drive Collar (Center): This stainless steel cylinder contains set screws used to lock the seal onto the pump shaft.
The Stationary Seat (Bottom): This is the metal-clad ring with a white PTFE or Ceramic insert that remains fixed in the pump's stuffing box.
