Gland packings are a traditional method of sealing pumps, valves and other equipment in rotary motion. Through use the latest achievements of material engineering and high-performance components, the modern packings are characterized by lack of health hazards and long working time. There are many types of gland packings, they are designed for specific applications and conditions, therefore a selection of suitable sealing material and right montage are necessary if we expect reliability and economical efficiency.
Gland packing Grafopak GRA 450
Gland packing made of a 99% purity expanded graphite, secured by the inhibitor from a galvanic corrosion risk. Designed for sealing of water impeller pumps, chemicals and petroleum compounds up to 450 °C, except strongly oxidizing and abrasive media.
Gland packing Grafopak GRP 420
Packing made of expanded graphite yarn with addition of carbon fiber, impregnated with PTFE dispersion. This packing has an excellent heat conductivity, a low friction factor, excellent self-lubricating properties. Furthermore it has higher tolerance to the stuffing box bad condition than pure graphite, it is less fragile and more easy to assembling.
Gland packing Karbopak XR 640
XR 640 packing is made of expanded graphite and high modulus carbon fiber C98 with addition of corrosion inhibitors. Its braid is made in form of reinforced corners, which significant affects the mechanical strength of seal, while keeping excellent sliding properties of graphite.
Gland packing Karbopak HR 660
Packing made of carbon fiber of high purity and thermal resistance with the addition of flake graphite. Karbopak HR 660 packing is braided in a wide range of square profiles and impregnated with a high-temperature lubricant in the form of graphite dispersion.
Gland packing Karbopak KA 400
Packing made of carbonized carbon fiber with impregnation of graphite dispersion. The high carbon content, strength and good sliding proprieties recommends this packing for dynamic seals of pumps in the range up to 300°C.
Gland packing Karbonyl KL 380
The packing based on phenol-aldehyde fiber with high contents of carbon and with PTFE impregnation. This fiber has a characteristic red-brown color and excellent mechanical properties, which combine both: softness low friction and high strength. On the contrary to aramid packing, the Karbonyl does not cause excessive friction and wear of pump rotating elements.
Gland packing Inkograf IGP 600
Packing based on expandable graphite (purity 99%), reinforced by wire made of nickel alloy. Sacrificial anode is used as the corrosion protection system. Designed for repairs and service of industry fittings and high-pressure valves, It is an ideal substitute of pure graphite die-form rings GDR.
Gland packing Inkograf HTR 650
Packing based on a metal-graphite composite, with corrosion inhibitor and antioxidant addition. Packing designed for closing rings of valves stuffing boxes and for maintenance of a high-pressure equipment.
Gland packing Tefapak GRF 260
Packing made of graphited PTFE. High chemical resistance, low friction factor, excellent mechanical properties. It is very soft and elastic packing, reliable and easy in assembling, highly valued by users, with a wide range of application.
Gland packing GRH 280
Packing made of thin strands PTFE foil incorporated with graphite. The GRH packing has 40% higher graphite content and at the same time higher strength compared to common PTFE graphited seals.
Gland packing Tefapak RAM 220
Packing based on expanded PTFE and ramie fibers with particularly high resistance to friction wear. It is a neutral packing with a pale-yellow color, economical and reliable, provided that there is no risk of chemical and temperature influences.
Gland packing Tefapak PUR 200
White packing made of 100% virgin PTFE with high purity. Designed for use in dynamic and static seals in hygienic condition also for work in chemical, pharmaceutical and food industry. Packing has health quality approval up to 260°C (acc. EU 10/2011).
Gland packing Tefapak BOL 210
Packing made of expanded PTFE, impregnated with lubricant based on composition special oils. Designed for sealing centrifugal pumps working with low level of contaminating solid particles and for water pumps.
Gland packing Arampak AG 360 / XG 340 / ZG 320
Hybrid packing composed of graphited PTFE and aramid yarn, in option as reinforced corners or interleaved through (zebra weave). Designed for impeller and reciprocating pumps for liquids with high dynamic interaction also abrasive and highly contaminated (sewage, dewatering systems and hydro-transport).
Gland packing Arampak AP 300
Braided packing of continuous aramid fiber with a characteristic yellow colour and particularly high resistance to abrasion. The AP 300 packing is impregnated with a PTFE dispersion to seal the pores, reduce a friction factor and improve elasticity.
Gland packing Arampak XP 310
The hybrid packing made from the composition of pure, expanded PTFE yarn with aramid fiber. Arampak XP has a characteristic zebra-corner braid, which gives higher durability along as well as across of rope. Moreover, the impregnation with PTFE dispersion seals space between filaments, reduces friction and improve sliding properties.
Service Pack 19
36-piece packing mechanic's kit designed for professional removal and montage packings in staffing box and industrial pumps and valves.
