    Why Traditional Packings Fail

    How a Stuffing Box Should Look When Completely Packed Using Traditional Packings
    How a Stuffing Box Looks After Several Gland Adjustments Using Traditional Packings
    Traditional packings are mostly fiber with added lubricants that can be squeezed, cooked or washed out, resulting in out-of position lantern rings, over-compressed packing and sleeve wear.

    Slade Packed Centrifugal Pumps: Typical Stuffing Box VERSES Slade Packed Stuffing Box
    Typical Stuffing Box: A typical stuffing box requires leakage and/ or flush-water to dissipate heat, creating costly housekeeping problems, loss of product and/ or loss of flush-water. Additional rings cannot be added without affecting position of lantern ring.

    Slade Packed Stuffing Box: In most applications, a Slade packed stuffing box can be run without flush-water and/ or with virtually no leakage. In many applications, both No-Flush & No-Leak are possible! Additional rings can be added as needed.

    Seals Rotating Equipment

    Whereas most pump packings are largely abrasive fibers with added lubricants that can be squeezed, washed or cooked out, Slade 3300G utilizes the self-lubricating qualities of the very best natural, exfoliated graphite.

    Incorporating just enough temperature and chemical resistant ‘ carbon fiber’ to make very high tensile strength yarns, Slade’ s patented technology allows the braided packing rings to transfer frictional heat away from high speed shaft sleeves, eliminating the need, in most cases, for cooling water.

    Since cooling or flushing is not typically required, there is no need for lantern rings. This eliminates the concern of the lantern rings being adjusted out of position, flush water ports becoming plugged, or sleeve wear caused by the corrosive nature of highly oxygenated water on hardened sleeves.

    3300G – Slade’ s Best All Purpose Pump and Valve Packing
    Reinforcement: Corners and yarns of graphite foil reinforced with high strength structural carbon fiber
    Temp: Mild Oxidizers to 1800° F/ 1000° C ( for temperatures over 1000° F/ 540° C, consult the factory)
    Pressures: Valves to 5000 PSI/ 350 BAR without end-rings
    Pumps: Flush-free in many services to 4800 FPM ( 1400 m/ min)
    pH Range:
    1-14
    Applications: Chemicals, steam, hydrocarbons, etc.
    Advantages:

    One packing inventory for all pumps and valves
    Works well on worn sleeves
    Difficult to overtighten
    No added lubricants to squeeze out or burn off
    Eliminates flush-water in most applications
    Not necessary to replace entire set, just add ring
    Won’ t glaze or harden
    Eliminates most leaks
    Amperage reduction of 15% is typical
    No special end-rings required
    Outlasts typical packings by factor of 6
    4800 fpm/ 24 ms ( without flush water)
    pH 1-14
    Operates virtually leak-free in most applications
    Low chloride/ sulfur available for nuclear service

    Installation:

    Check clearances and dimensions
    Best to use no more than 5 rings in stuffing box ( use Slade spacer bushings to reduce rings)
    Cut rings on the bias ( 45° angle) , stagger joints
    Compress each sealing ring at least 25% ( especially the first ring) . Do not compress spacer bushings.
    Loosen gland to allow it to relax
    Snug the gland bolts and start the pump

    3300GLC: Low chloride for nuclear service
    3300GLS: Low sulfur for nuclear service

    Advantages

    Minimizes or Virtually Eliminates Leakage!
    Due to its patented construction of natural, expanded graphite yarns, Slade 3300G turns the stuffing box into a heat sink, conducting heat away from shaft, in many applications, eliminating expensive leakage previously needed to cool the stuffing box.

    Can Be Operated Flush-Free in Most Applications
    Slade 3300G conducts heat away from the shaft/ sleeve, in most cases making flush unnecessary. If media has particulate contamination, a very mild flush should be all that is required.

    No flush-water translates into:

    Exceptional savings, typically 1/ 2 cent per gallon, or $ 13, 000 annually ( U.S.) ( based on 5 GPM flush system)
    No fear of flush-water system becoming plugged or experiencing loss of pressure

    Reduces Inventory and Cost

    By eliminating die-formed rings ( cut-rings work fine)
    Handles most medias, 1-14 pH, eliminating many styles of packing
    In many applications, no need to remove old packing, just add a ring
    Lasts 4 to 6 times longer than traditional pump packings

    Worn Shafts and Sleeves Easily Sealed
    Conforms to the geometry of the stuffing box and shaft. Seals most worn sleeves.
