Chesterton’s new Streamline™ S-Series is engineered to meet the majority of plant-wide applications with great service reliability. 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 plant-wide use
• Common design with interchangeable parts
• Outstanding performance and value
• Two-step "bolt & go" installation
• Rebuilding options smooth workflow

• S-Series Common Parts reduce inventory while increasing options
• Same gland is used for both the single and dual seals to maximize flexibility. Interchangeable cassettes 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.
• 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.
• Multi-Port Flush cleans better and prevents localized thermal seal face distortion common with single port systems.
• Floating Throttle Bushing for maximum safety is standard.
• Fluids are diverted to quench and drain ports.
