  • Chesterton 180H Single Cartridge Seal

    An exceptional high temperature seal, the Chesterton180H Single Cartridge Seal uses an advanced hydropad geometry seal face that improves film formation between the mechanical seal faces and significantly enhances face lubricity. The increased film formation between the faces reduces heat generation and increases seal life in many high temperature applications.

     

    Hydropad designs are useful in high-pressure applications—​where pressure has a tendency to distort the seal faces and where the face velocity increases heat generation and in sealing fluids that have poor lubrication properties. Hot water applications are a prime area where hydropad technology can be utilized to improve sealing reliability. The 180H seals water at high temperature without environmental controls to temperatures up to 260°C (500°F).​

     

    Features:

    • A high temperature seal also designed for high speed and pressure
    • External cooling requirements are not needed for most applications, eliminating support equipment
    • Advanced hydropad geometry minimizes seal facewear and distortion
    • Reduces the frictional seal face heat concerns common with standard contacting seal face designs
    • Hydropad geometry increases pressure velocity parameters over standard seal face designs
    • Compact cartridge design for easy and reliable installation
    • Use where external cooling is intermittent, limited, or unavailable
  • Chesterton 1810 & 2810 Heavy-Duty Modular Cartridge Seals

    ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​1810 Heavy-Duty Modular Single Cartridge Seal

    This Chesterton® single cartridge seal offers you the ultimate in seal quality, flexibility, and emissions control.

     

    Leveraging Chesterton’s proprietary AXIUS modular platform, the 1810 can be configured with several different face profiles and auxiliary components within a common gland housing. This flexibility allows seal performance to be tailored to a wide range of process conditions.

     

    A plant-wide sealing solution, the 2810 uses a geometric double​-balanced seal face design. An optimized barrier/buffer channel for enhanced fluid flow provides greater seal reliability even at elevated temperatures.

The PTFE resin is combined with graphite and expanded by using the latest technologies, resulting in a high-quality filament.​​

    Features & Benefits 

    • Excellent chemical resistance
    • Low friction, less heat generation, and non-abrasiveness saves shafts and shaft sleeves
    • Easy installation and removal​​​​
    • Low leakage and long life​​​​
  • Chesterton 1830 SSP Slurry Pump Packing

    ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​Chesterton 1830SSP Slurry Pump Packing is manufactured with a hybrid yarn, combining advanced, expanded, graphite PTFE yarn with carbon yarn reinforcement. This unique construction of yarns yields a packing that is easily removable during repack, resulting in reduced downtime. 1830SSP can be used in a wide range of slurry sealing applications, from a submersible slurry pump to a mining slurry pump.

    1830 SSP Slurry Pump Packing Features & Benefits:

  • Chesterton 329 Stern-Lon Marine Flax Shaft Packing

    Chesterton 329 Stern-Lon®​ is square-plait-braided to provide an unusually flexible, formable sha​ft packing. The base fiber is a long-fibered, roved flax of the highest quality. 329 is graphite-free to avoid galvanic corrosion on shafts. ​

    During production, 329 is first impregnated with concentrated PTFE dispersion to promote non-flowing lubricity and to retard degradation. This is followed with a plasticizing “break-in” lubricant which assures compressibility, flexibility, and good packing-to-shaft contact. Large sizes need not be hammered into place. Finally, to minimize frictional attrition, a finely divided fluorocarbon powder is embedded into the surface of the packing.  Chesterton 329 produces little or no shaft or sleeve wear.​​

    Features & Benefits
    • Suitable for stern tube and paper mill packing
    • Most recognized product for the marine industry in Stern tubes
