Cartridge Mechanical Seal

The SONTEK™ XA Mechanical seal is a high-performance Mechanical Seal typically used in industrial pumps. XA Mechanical Seal is a factory-assembled, pre-set sealing unit designed for centrifugal pumps and rotating equipment. XA Mechanical Seal is a single, unbalanced mechanical seal used in pumps and rotating equipment to prevent leakage of fluid along the shaft. It works by pressing a rotating seal face and a stationary seal face together, creating a tight sealing surface. Springs and secondary seals (such as O-rings) maintain contact between the faces and ensure proper sealing. XA mechanical seals are commonly used in centrifugal pumps, water systems, and light chemical applications because of their simple design, reliability, and easy maintenance. Main Components Rotary Face – Attached to the rotating shaft and rotates with it. Stationary Face (Seat) – Fixed in the seal housing and does not rotate. Secondary Seals – O-rings or gaskets that prevent leakage between components. Spring or Multiple Springs – Provide axial force to keep the seal faces in contact. Metal Parts – Hold and support the seal assembly.Working Principle The rotary and stationary faces press against each other to form a sealing interface. A very thin film of fluid forms between the faces to reduce friction and wear. The spring force maintains constant contact between the sealing faces even when the shaft moves. Features Compact and simple design Easy installation and maintenance Good sealing efficiency Suitable for water, oil, and light chemicals Applications Centrifugal pumps Water treatment plants Chemical processing industries Food and pharmaceutical equipment

The SONTEK™ 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. Offered by Nexton Seals in Chawri Bazar, Delhi, this seal is widely preferred by pump dealers, repair workshops, OEM manufacturers, and industrial maintenance contractors. 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. The Drive Collar (Middle Component) The stainless steel cylinder in the center is the Drive Collar. Function: It features set screws (the small holes you see) that tighten onto the pump shaft. This is what physically 'locks' the seal to the shaft so it rotates at the correct speed.
