The cost-effective general-service packings constructed of the highest-quality synthetic fibers and lubricants. These products are designed to handle a wide range of fluids at moderate to high temperatures, pressures and shaft speeds. These styles are thoroughly impregnated with PTFE to enhance chemical resistance, lubricity and dimensional stability. This helps to ensure even gland load distribution and to promote longer packing life.
Features
High density, dimensionally-stable
Very little water absorption
Ideal for valve and slower shaft speed applications
PTFE dispersion ensures low friction and prevents leakage through the braid
Resistant to most chemicals
Applications- Check and needle valve stems
- Reciprocating rods
- Rams
- Plungers
- Safety injection system valves

Install adjustment:
1.The screw conveyor can not be installed until the dust stuck during transportation or unloading
is cleaned.
2.Material groove center line and screw shaft should have an appropriate coaxial degree.
3.The drive device and the screw shaft should have a right coaxial degree.
4.The static equilibrium test should be carried out after the screw is installed.
5`After the conveyor installed, check whether there is any debris in the machine and if the lubrication is enough.
6.During the no-load test, the bearing should be oil-tight, and the bearing temperature should not be higher than 20℃. During the load test,the temperature of bearing should not exceed 30℃.
Attentions
(1) Lubricate the bearings, gears, chains and other transmission parts regularly.
(2)When the box-to-send machine stopped, check the abrasion of the spiral blade and repair and weld it when it wears seriously.
(3)The conveying amount can not be overloaded, otherwise the material will not be discharged, which may cause the screw shaft bending and box expansion.
(4) In the operation of the conveyor, if the noise is harsh, you should open the lid to check it and troubleshoot.
