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.

How a Stuffing Box Should Look When Completely Packed Using Traditional PackingsHow 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 BoxTypical 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.
Flush-Free & Virtual Leak-Free ServiceDepending on design of equipment and speed of shaft, a permanent split bushing may be installed last (after 3300G Rings). Please contact us for a recommendation.
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.

Replaces expensive Mechanical Seals
The SLADE DSS Sealing System can achieve Mechanical Seal
performance at packing costs.
DSS Bushings are hinged to install without dismantling the pump
An alternative to machining costly bushings is to utilize Slade's DSS Sealing System. No machining, no dismantling of the pump. Achieve leak-free, flush-free service. It comes fully unitized, ready to install, and we'll inform you of the gland compression required. If you follow Slade's installation instructions, you eliminate fear of over-tightening.
Contact Slade for information on the DSS bushings.
- Check clearances and dimensions
- Best to use no more than 5 rings in stuffing box (use DSS rings, Slade's spacer bushings, to reduce rings)
- Cut rings on the bias (45° angle), stagger joints
- Compress each ring 25%-30% (use packing compressors as needed)
- Loosen gland to allow it to relax
- Snug the gland bolts and start the pump
