Gland Packings

Rectangular cross-section braided packings are designed for sealing rotating shafts, reciprocating pistons, static flanges/lids and valve stems.

Various Gland Packings

 

Packings are divided according to different raw materials:

1. P.A.N. (Poly Acryl Nitrile) fibre in combination with either carbon fiber or PTFE
Temperatures: -40 C° +250 C°
Pressure: up to 100 bar
Rotary speeds: up to 18 m/s

2. Glass fiber combined with PTFE, Inconel, or graphite fiber
Temperatures: -100 C° +550 C°
Pressure: up to 250 bar
Rotary speed: up to 12 m/s

3. Kevlar or aramid fibers, for an abrasive environment, combined with PTFE or graphite fiber
Temperatures: -100 C° +280 C°
Pressure: up to 400 bar
Rotary speed: up to 20 m/s

4. PTFE fiber packings
Temperatures: -200 C° +280 C°
Pressure: up to 200 bar
Rotary speed: up to 12 m/s

5. PTFE and graphite fibers or a combination of Gore fibers
Temperatures: -200 C° +280 C° (up to +2760 C° in an inert atmosphere)
Pressure: up to 150 bar
Rotary speed: up to 25 m/s

6. Carbon and graphite fibers
Temperatures: -150 C° +650 C°
Pressure: up to 300 bar
Rotary speed: up to 30 m/s

7. Expanded Graphite fibers or a combination with Grafan fiber
Temperatures: -200 C° +600 C° (up to +3000 C° in an inert atmosphere)
Pressure: up to 360 bar
Rotary speed: up to 30 m/s

8. The natural-fiber (Cotton, Ramie China nettle) combined with PTFE or graphite fiber
Temperatures: -30 C° +120 C°
Pressure: up to 130 bar
Rotary speed: up to 12 m/s

There can be used packing extractors or corkscrews to remove old packing.
