Chesterton’s new Streamline S-Series is engineered to meet the vast majority of plantwide applications with great reliability in service.  The S-Series goes beyond the basics of fluid sealing, to address the economies of total sealing workflow.  S-Series will streamline inventory, simplify seal selection, reduce installation complexity and minimize total maintenance costs.

Simply superior for standardization, workflow efficiency and value. 

• Optimized design for plantwide use
• Common design with interchangeable parts
• Outstanding performance and value
• Two-step "bolt & go" installation
• Rebuilding options smooth workflow

Chesterton’s S20 Dual Cassette Seal

• S-Series Common Parts reduce inventory while increasing options.
  • Same gland is used for both the single and dual seals to maximize flexibility and streamline repair administration.
• Optimized Seal Faces balance low heat generation and distortion to handle a plant’s toughest applications. 
  • FEA design and robust body withstand high pressures and torques compared to general duty designs.
• Self -Centering Lock Ring™ is a patented mechanism that ensures sleeve concentricity and squares the rotary face to the shaft during installation.
  • This prevents seal face wobble, increasing reliability in tough emissions and slurry services.
• High Torque, Cushioned Drives eliminate metal to seal face contact on all S-Series faces. 
  • Cushioned drives minimize shock and vibration.
  • High strength drive pads resist shear load in tough applications.
• Captive Centering Pads set precise positioning automatically, then move out of the way at start-up. 
  • Non-sparking for safety, and never misplaced for future use.
• Micropolished Faces reduce drag for maximum face responsiveness.
  • Highly polished surfaces ensure face tracking.
  • Seal face hang-up is minimized.
• Fully Vented Gland ensures that liquid surrounds the seal.
  • Eliminates air spaces that prevent barrier fluid flow and increased seal operating temperatures.
• High Flow Pumping Ring cools inboard and outboard seal faces in high temperature services.
  • Aggressive bi-directional vanes combine with cutwaters to deliver high flow.
• Tandem Configuration seals on the OD of both sets of seal faces. 
• Balance Piston™ enables true hydraulic double balance with no moving O-rings to hang up and fail under pressure reversals.  Patent pending, it eliminates the need for wide seal faces, which generate excessive heat and contribute to O-ring failure.
