Garlock Compression Packing: The way to more operating efficiency Garlock Compression Packing One of the oldest sealing methods is the use of braided fibers. Due to continual industrial development, the required standards for sealing technologies in general as well as those in the compression packing sector have increased accordingly. Which has resulted in the development of new materials and led to less packing diversity. To satisfy these demands, application oriented research and the use of new fiber technologies have become vital. The advantages of Garlock Compression Packing at a...

Garlock Compression Packing: The way to more operating efficiency The combination of asbestos-free fibers and PTFE offers an economical standard packing for pumps. Pumps in mild acids and alkalis, air and dry industrial gases, petroleum and synthetic oils, aromatic and aliphatic solutions, cooling water, salt water and steam. An adaptable packing made of PTFE-Graphite-Yarn woven in a Lattice Braid® mesh. For pump and agitator applications with low friction values. pH PTFE-Packing with high temperature lubrication for use in rotary service. Pumps, mixers and agitators for virtually all...

Garlock Compression Packing: The way to more operating efficiency A synthetic packing with Aramid Corners and PTFE Impregnation (Infusion), for use in abrasive media with minimal leakage. Also suitable as a valve packing. For sand, slurry and salt solutions where a long service life is required. An Organic Polymer Fiber Packing developed by Garlock. Before and after the weaving process every fiber is PTFE impregnated, making it a perfect general-purpose packing for pumps and valves. A packing braided from flexible graphite yarns reinforced with graphite fiber providing greater tensile...

Garlock Compression Packing: The way to more operating efficiency Pure graphite packing rings are pre-pressed special packings for high stress valve stem sealing. Pure graphite is a binder-free sealing material with exceptional chemical and physical properties. The main application areas are the sealing of steam, hot water, heat transfer oils, acids, alkalis, solvents, oxygen and gases. * 500 °C in atmosphere, 650 °C in steam, 3000 °C in an inert environment.

Garlock Compression Packing: The way to more operating efficiency Leaders in Sealing Integrity Braided valve stem packing This modern packing set consists of two different compression packings that are available either in prefabricated sets or in dispensing boxes with color coded braid. The spool boxes reduce storage costs and production outage without compromising sealing performance. Outage planning is easier than ever now that each 212-ULE box indicates how many typical valves can be repacked by one box. Benefits 212-ULE » Environmentally friendly performance and packaging » Double...

Garlock Compression Packing: The way to more operating efficiency 8093 DSA Pump Packing 8093 DSA Pump Packing Suitable for high-speed installation and adjustment to obtain ,minimum-leakage'. By combining the properties of flexible graphite rings and braided packings, the Garlock 8093 DSA is the ideal fusion of these two separate conventional sealing systems. Condition as supplied (uncompressed) Mounting condition (compressed) | Gasket (GYLON®, G-9900) Braided rings High density GRAPH-LOCK® adapter rings | Low density GRAPH-LOCK® sealing rings Benefits 8093 DSA Pump Packing » High chemical...

QUICKSET® 9001 QUICKSET® 9001 combines the advantages of the 9000 EVSP Valve Stem Packing in an improved, even more compact design. This set is primarily designed for control valves where simplified installation and a minimum of friction is required. QUICKSET® combines two tested, emission-reducing materials within this set: 1303-FEP Packing and 9000 EVSP. The system consists of 5 rings. Three low density pure graphite rings are held by two preformed high density 1303-FEP adapter rings. The reduction of all the rings is based on the Cup and Cone design similar to that of the 9000 EVSP. The...

Garlock Compression Packing: The way to more operating efficiency Packing cross section The packing cross section should always be in relation with the shaft diameter. The following formula is recommended: » Pumps s=1,4 to 1,6xVd Number of packing rings Normally 4-6 packing rings should be used. However when operating conditions call for special solutions a higher number of rings can be utilized. In this case each ring should be pre-pressed. The GYLON® discs between the individual packing rings stop the extrusion of packing and lubricant. » For use of packing with a risk of probable...

Installation Instructions Preparation All old packing rings and residual material must be removed before commencing with a new installation. The stuffing box and shaft must be completely clean. Shafts and sleeves must be checked for wear and scoring, and if excessive, replacement is mandatory. If the sealing gap between shaft and housing is large then an anti-extrusion ring should be employed. Valves The following formula is recommended for the calculation of the correct packing-ring-length: La = (d + s) x n x 1,03 (see sketch) and, where possible, a diagonal 45° cut should be used. Each...
