GORE® GFO® Fiber

The right packing for reliability and savings

Typical Applications
Shafts on high-speed pumps, mixers, agitators and other rotary equipment

Compression packings typically used in:
  • Pulp and paper manufacturing
  • Mining and minerals
  • Power generation
  • Municipal wastewater treatment
  • Steel manufacturing
  • Marine
  • Petrochemical
  • Chemical processing

Plant operators often are not aware that similar looking compression packings do not perform the same, leading to significant hidden costs. While procurement has a tight hold on the upfront packing cost, the greater cost takes place in operation.

Packings with 100% GORE GFO Fiber can provide maintenance engineers with consistently high performance general service packing for wide application and use, including sealing shafts on high-speed pumps, mixers, agitators or any other equipment with rotating or reciprocating shafts. They don’t become hard or brittle, are temperature and chemically tolerant and easy to install and remove. Plant operators can be assured that packings with 100% GORE GFO Fiber will consistently deliver the trouble-free performance they need.

What makes the GORE GFO Fiber Unique?

A sustainable solution

Gore has tested packing made of 100% GORE GFO Fiber alongside generic graphite/PTFE packings.

Packings made of 100% GORE GFO Fiber achieve better results for all attributes. The differences in performance for each generic packing will have an impact on the operational costs. The example below shows an estimate of the savings that can be made by using packing made of 100% GORE GFO Fiber.

Annualized costs savings (estimated)

Based on calculations for a 100 psi (6.9 bar) pump, 2 inch saft (50 mm); Drip rate 25,000 gallons (94.6 m3)/ year; Packing = $40; Replacement of packing = 3 times per year; kWh = $0.12

Outperforms generic PTFE/graphic packings

This video clip shows the leakage rate difference between a packing made with 100% GORE GFO Fiber versus a generic PTFE/graphite packing.

Quality assured

Many PTFE/graphite packings are available in the market. While they may all look the same, it is worth noting that there are huge inconsistencies in the actual product quality and performance of many of the packing solutions offered. The installation of these products can increase operating costs (power, water, maintenance) and risk of premature failure as well as unscheduled shutdowns. Such problems can cost a lot of time and money.

To help overcome these challenges, Gore created the Seal of Assurance Program. Through a global network of authorized braiders, this program ensures that every fiber used to braid the packing is a GORE GFO Fiber. Look for the 100% GFO seal on the box and print right on the packing –— it’s the only packing that is identified this way!
