Which Gland Packing Is Suitable for You? | Expert Guide by DEMINAS UK
Choosing the right gland packing is critical for the safety, efficiency, and lifespan of your equipment. Whether you're dealing with water pumps, valves, or high-pressure steam systems, DEMINAS UK has the gland packing solution for your application.
What Is Gland Packing?
Gland packing (also known as compression packing) is a sealing material used around shafts and stems in pumps and valves. Its job is to prevent fluid leakage under pressure or temperature changes — a must in demanding industries like:
- Water treatment
- Chemical processing
- Marine
- Oil & gas
- Power generation
DEMINAS offers a wide range of PTFE, graphite, aramid and much more designed to meet the needs of each sector.
How to Choose the Right Gland Packing
When selecting the best gland packing, consider:
Temperature & Pressure Range
- Graphite gland packing is ideal for high-temperature, high-pressure applications like steam valves also using reinforced graphite packing for higher temperatures.
- PTFE gland packing works well in chemical environments due to its resistance to acids and alkalis, but is much more popular in spaces where hygiene and non-contamination is needed, such as food and water processing as it is FDA Approved.
Chemical Compatibility
- If you're working with aggressive chemicals, PTFE or PTFE-Graphite gland packing is the safest option.
- For abrasive slurries and corrosive applications, a blend of aramid and graphite may perform better.
Application Type
Pumps: Use softer packing with good lubrication to minimise shaft wear.
Valves: Choose a denser packing with lower leakage rates.
| Type | Best For | Temp Range |
|---|---|---|
| Graphite | Steam, thermal oil, high-temp valves | Up to 550°C |
| PTFE | Chemicals, food-grade, clean systems | Up to 260°C |
| Aramid Fiber | Abrasives, slurry, high-pressure pumps | Up to 280°C |
| Graphite PTFE | Mixed services, rotating shafts | Up to 280°C |
