Sealants are used for stuffing box packing glands of pumps, valves and fittings. Depending on the packing of the working environment, temperature performance and safety requirements, are offered with the sealants of expanded graphite yarn, polytetrafluoroethylene (PTFE), and aramid. There are also reinforced with inconel sealant designed to operate at high temperatures. All sealants are made in the form of strings of the square, have a low coefficient of friction, high chemical resistance and good conductivity. In addition, materials are not posing a threat to human health and the environment, and easy to use and economical storage. Graphite packing They are made in the form of strings of the square, with the expanded graphite with a purity of 99% of the fiber and corrosion inhibitors. The enhanced version is made with extra yarn reinforced with inconel.

Density in the range 1-1.2 g/cm3. Sealants are designed to exercise motor seals for pumps, valves and static seals in the temperature range to 600 ° C, for water vapor to 550 oC. Sealants are low friction, self lubricating, high chemical resistance, very good heat conductors. Moreover, they are lightweight and easy to form, provide high performance with the performance of seals. PTFE packing Is manufactured from expanded polytetrafluoroethylene (PTFE) in the form of square ropes as clean and with the addition of graphite as a substance, ennobling. Density in the range 1,3-1, 6 g/cm3. It is designed to perform the gland sealing pumps and valves in the temperature range to 280 ° C, also in the food and pharmaceutical industries. A very low coefficient of friction and high chemical resistance. In addition, flexible and soft sealant with PTFE is easy to use and durable, is a proven and very popular with the sealing material. Types of sealants and their purpose: - GRAFOPAK Active - Flexible graphite packing glands to centrifugal pumps and valves -

INKOGRAF - Graphite with inconel fittings for industry and energy. - TEFAPAK Graf - PTFE, graphite, universal for centrifugal pumps, piston and valves. - TEFAPAK Pure - White PTFE for food and pharmaceutical industries: pumps, mixers and static seals, has a positive testimony to the National Institute of Hygiene of foodstuffs. Installation and operation Detailed information on the selection, assembly and use of sealants available in a separate manual. We recommend it especially for users who have previously used the other types of sealing materials. A number of standard dimensions of the table allows you to perform the full range of seals from 4 mm to 28 mm. In order to achieve the intermediate dimensions, use the flexibility and ease of forming the sealant in a small range of + / - 10%. The table also served a practical calculator to determine the required amount of a particular type and level of packing.
