Maintenance engineers to be kitted out
Gland packing range added to catalogue Farnell has added its Klinger range of gland packings to its Industrial catalogue. The Klinger range includes seven types of gland packing material and is available in sizes to suit most pump and valve equipment. Klinger's q]cpe 10 gland packing is highly versatile, and is suitable for sealing a wide range of media, including water, petroleum and weak acids. It is available in a range of sizes and is flexible and clean to handle. The Type 3222 offers good chemical resistance and high temperature capability, for all round good perfbrmance in valves and pumps. Type 11 gland packing is suitable for use as a high temperature substitute to asbestos. Graphited and lubricated, this type is able to withstand temperatures of fluids up to 300 °C.

dustry, PTFE thread tape, grease/ anti-seize compound, plus the special instruments and tools that are essential for removing and replacing compression packings. Andrew Goulding, James Walker Compression Packings Division general manager, explained that the kits are typically taken on-site by the company's technical experts. They were so admired by maintenance engineers, that James Walker decided to make them commercially available. The self-contained kits are supplied in sturdy, clearly marked and lockable tool boxes.

Maintenance Cryogenic engineers to pump seals be kitted out offer unique performance
James Walker now supplies maintenance kits for repairing gland leaks on pumps and valves.
The new kits provide all the special tools and compression packings that are needed to make urgent repairs, quickly and effectively. Different versions of the kits are supplied to meet the exacting demands of the water, power generation, food, pulp and paper, and chemical industries. They contain a range of compression packings, selected to suit the particular in-

Flex-A-Seal has developed cryogenic seals specifically designed to positively seal centrifugal pumps used in the transfer of liquefied gasses, such as nitrogen, oxygen and argon. The seals are also suitable for process systems, storage tanks, trucks, transfer stations and other low temperature applications, and offer performance, construction
materials, service life and design features not iound in other seals of this type. Previously, to seal low temperaturc applications, end-users typically used hydro-formed bellows seals, which often failed and deformed because of their inherent design and materials of construction. Tbey also did a poor job of maintaining critical film lubricant. Consequently, seal faces deteriorated, making face loads difficult to maintain and seal repair virtually impossible. Flex-A-Seal's cryogenic seal faces are a combination of cryogenic grade graphitic carbon with a tungsten carbide rotating seat, specifically developed to operate at lower temperatures. The result is a higher PV value, and excellent film fbrming properties, which in effect, achieves a state of self-lubrication. An edge-welded 347 stainless steel bellows core provides extremely accurate control of face loading, belps maintain proper lubrication, and allows for higher pressure capabilities. The edgewelded bellows technique eliminates "thin-spots" and stress points on the inside and outside seal diameter, provides for more reliable compression, and is stronger and more repairable than the rolled bellows. The cryogenic seal design is the result of four years of research and development, as well as extensive field testing. Contact: Flex-A-Seal,One Jackson Street, PO Box 184.
