What is PTFE gland packing used for?
PTFE Packing: Designed for use in dynamic and static seals in hygienic condition also for work in chemical, pharmaceutical and food industry.
What is the difference between gland packing and mechanical seal?
Packing seals use rope-like materials that wrap around the shaft of a pump, filling in dead space and minimizing fluid loss. Mechanical seals are more durable than their predecessors and are designed to take much more punishment. Basic mechanical seals use multiple sealing points to nearly eliminate any leakage issues.
Where is gland packing used?
Gland packing is used extensively for the sealing and restriction of leakage of the working fluid along the stem in valves and along the shaft in the case of pumps and also for stationary duties like manhole cover sealing.
What is graphite gland packing?
Graphite packings are self-lubricating, dimensionally stable, impervious to gases and fluids, and corrosion-resistant. Graphite gland packings are best suited for dynamic sealing of centrifugal pumps for water, petroleum derivatives, and other chemicals, particularly under conditions of high speed and high pressures.
What is a gland packing seal?
Gland packing is a conventional shaft seal which is preferred by mechanical engineers. In Gland Packing, rope-like braided material is packed around the shaft. Thus, the gap between the pump and shaft gets filled with the packing material. The packing also requires frequent adjustment and lubrication.
What material is used for gland packing?
“Gland packings are made of a combination of different materials such as cotton, glass, aramid, acrylic, PTFE, and graphite fibres and they are manufactured in plaited, braided, twisted, jacketed, corrugated foil, foil wrapped deformable core and full foil form.
What is gland packing made of?
Different Types of Gland Packing (Materials used) The packing made of a combination of graphite, carbon, glass, etc. are used for harsh applications whereas gland packing made of materials like Jute, flax, hemp, and cotton are used for light applications like sea water, potable water etc.
What are graphite rings used for?
Die-formed expanded graphite rings are widely used as gland packings in modern process valves for higher temperatures. The development of this sealing solution started in the 1970s and is defined by the characteristics of the expanded graphite material.
