STANDARD DIN/ANSI DUAL CARTRIDGE SEALS

CarLife 299

  • PATENTED

    CarLife® 299TM

    THE MOST VERSATILE YET AFFORDABLE SEAL IN ITS CLASS

    In a back-to-back arrangement, the CarLife 299 cartridge seal continues to impress customers with its competitive price, field proven reliability, and large runout capability beyond industrial requirements, and has already been widely used for a broad range of applications across various industries.

    As a paradigm in the design of the CarLife family, the CarLife 299 features part interchangeability between inboard and outboard seals. Moreover, besides similar construction and assembly procedure, the family shares major parts. More shared parts mean simpler maintenance process and inventory management. As a result, our CarLife customers are able to stock fewer inventory parts and pay much lower maintenance and inventory holding costs. And the more CarLife products they use, the more benefits they can gain from their cost-effective CarLife seals.

    Applications

    • Ability to tolerate short intermittent dry running in batch charging and discharging equipment.
    • Prevent hazardous emissions of acidic, caustic, corrosive, volatile and toxic media.
    • Withstand dry running involved with frequent starts and stops.
    • Suitable for a wide range of rotating equipment, such as chemical process pumps, vertical pumps, centrifugal pumps, vacuum pumps and eccentric screw pumps.
    • Widely used in the alcohol (e.g. methanol and ethanol), bio-diesel and corn processing industries.
    • Suited for a variety of industrial applications, including refining, petrochemical, chemical, food and beverage, pharmaceutical, pipeline transportation, power generation, steel, semiconductor, electronics, biotechnology, water resource, and wastewater treatment.

    Specific Features

    • The patented cartridge design features innovative drop-proof springs, thereby speeding installation and maintenance.
    • Our jumbo coil springs have better wear resistance than many other brands.
    • Balanced design for both pressure directions, promoting a higher level of sealing stability.
    • Flexible piping plans with a barrier/buffer fluid pressurized or unpressurized, depending on the application.
    • Robust construction with large runout capability.
    • Self-aligning compensates for shaft runout up to ±0.8 mm, increasing operational reliability.
    • Micro-polished outer surfaces of O-rings for anti-stick mounting.
    • Natural circulation heat exchanging design delivers bidirectional cooling flows at high flow rates, greatly extending MTBF (Mean Time Between Failures) because ofless heat.
    • Monolithic sealing faces with precise dimensions and excellent resistance to wear.
    • Low emissions design effectively contains VOC emissions.
    • Interchangeable inboard and outboard sealing faces.
    • Maximum interchangeability of parts among the CarLife family.
