STYLE - 1052 PURE PTFE PACKINGS WITH PTFE DISPERSION

Construction: Excellent tensile strength yarn made from a special grade of PTFE, &impregnated with PTFE dispersion

Technical Parameters:

Applications:

Absence of oil, so recommended in areas where there is danger of combustion. Used in pumps & valves having low shaft speed. Recommended in equipment handling hazardous & corrosive chemicals. Fast & simple to install with minimum maintenance requirements. PTFE packing has particular characteristics such as low coefficient of friction, high chemical resistance and excellent tightness, making it suitable for static, rotary & reciprocating applications.

RUBBER CORE PTFE PACKINGS WITH PTFE DISPERSION: PTFE packing can be made available with silicon / rubber solid or hollow core. A specially developed teflon packing for use on rotating equipments with excessive shaft deviation. We are manufacturers, suppliers, and exporters of ptfe packing and dispersion in Mumbai India to all over the world. It also reduces shaft / sleeve wear. The center of silicon core / cord gives it strong restoration properties and exerts back-pressure, resulting in total sealing. Teflon packing is suitable for pumps, reactors, mixers, agitators, etc.

INSTALLATIONS INSTRUCTIONS FOR PACKINGS

1	When rings are to be formed from continuous length of teflon packing, spirally wrap the packing around a rod of diameter equivalent to the valve spindle. Cut the required number of rings to fill the packing space, with a sharp knife to obtain good butt joints.
2	Remove all old packing carefully.
3	Clean properly all the surfaces that will be in constant contact with the packing and if possible apply lubricant. Check ptfe packing and neck bushes and spindle or shaft surface for wear and repair if necessary.
4	Place the first ring around the spindle or shaft by opening to an “s” configuration to ensure that the ring is not damaged.
5	First partially enter both ends of the first ring simultaneously into the stuffing box and then insert the remaining part of the rings. After that firmly push it to the bottom of the stuffing box. Assist with split sleeve
6	Similarly insert other rings and ensure that the joints are at 90^o. N.B: rings must be fitted individually and not as a set

FOR PUMPS APPLICATIONS

1	When all the rings have been fitted to fill the stuffing box, fit the gland follower and tighten the gland nuts to level the gland spigot. Tighten up to finger tightness only, then turn nut by one or two thread, loose it back & again tighten up to finger tightness again. (when storage is anticipated the gland should be left slack.) DO NOT OVERTIGHTEN.
2	Run pump up to operating speed for 10 to 15 minutes. If there is no leakage, stop pump, and loosen gland further. Repeat until leakage occurs. The controlled leakage, essential for lubrications purpose, can then be obtained by running the pump and evenly tightening teflon packing in increments of two threads until approximately one drop every few seconds is obtained. Approximately 15 minutes should be left between successive adjustments.

FOR VALVES

1	When all the rings have been fitted to fill the stuffing box, fit the gland follower and tighten the teflon packing to level the gland spigot. Tighten evenly until spindle has been tightly gripped then ease off the gland nuts so that the spindle will just turn. The system pressure can now be introduced.
2	After a few hours service it is advisable to check the gland adjustment for any looseness that may have taken place due to initial setting in.
