Specifications
Polytetrafluoroethylene (PTFE) is one of the best corrosion resistant materials in the world. Therefore, it is called "the king of plastic". So the PTFE mechanical seal can be used in any kind of
chemical medium for a long time.
PTFE Teflon Bellow Mechanical Seal for Sale
China PTFE Teflon Bellow seal has been widely applied in the area of atomic energy, defense, aerospace, electronics, electrical, chemical, mechanical, instrument, instrument, building, textile,
metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and smelting industries, and has become an indispensable product.

Application of PTFE Bellow Mechanical Seal
The mechanical seal of the PTFE bellow seal, which adopts the multi-spring structure, is the most widely used mechanical seal in the corrosion resistant pump.
Following is the Operating parameters:
Specification: 35~65mm
Temperature: -10 C ~+100 C
Pressure: less than 0.5MPa
Line speed: 15m/s
Axial channeling: + 0.5mm
Suitable medium: strong acid, strong oxidizing agent and other strong corrosive media.
Main Advantages of PTFE teflon mechanical seal
PTFE bellow seal can be applied to the fields of food, medicine, medicine and so on.
PTFE bellows seals for pumps has the function of physiological inertia, sterilization and disinfection.
PTFE bellows seal design has small friction resistance, no adhesion and creeping effect; high pressure;
PTFE bellow seal has good resistance to deformation and resistance to extrusion; it is easy to install and complete in size.
The elastic inner core has good elasticity, which greatly improves the sealing effect of PTFE mechanical seal.
Performance of the Welded PTFE Bellow Seals
1. High-temperature resistance: PTFE bellows for pump has little affected by the temperature,, the range of temperature range is wide, can be used at -190~260 C.
2. Low-temperature resistance: with good mechanical toughness, even if the temperature drops to -196 C, PTFE seal can also maintain 5% elongation.
3. Insulation: PTFE mechanical seal not affected by the environment and frequency, the volume resistance can reach 1018 ohm/cm, the dielectric loss is small, and the breakdown voltage is high.
4. High lubrication: the friction coefficient of the solid material is the lowest; the known solid material can not adhere to the surface, and it is a kind of solid mechanical seal with the
smallest surface.
5. Strong self - moistening: the friction coefficient of the solid material is 0.04 with the smallest coefficient of friction in plastic. PTFE bellows seal design is an ideal oil free lubricating
seal.
6. No poison: physical inertia, seals can be used in the vast majority of the pump body; aging resistance can be used in the atmosphere for a long time;
7. Pollution prevention: the blank value of metal elements is very low, the content of lead is less than 10-11 g/ml, and the content of uranium is less than 10-12 g/ml.
8. Resistance to atmospheric aging, radiation resistance and low permeability: even though the PTFE seal is long exposure to the atmosphere, the surface and performance remain unchanged.
9. Chemical corrosion resistance and weatherability: PTFE bellow seal is hardly corroded by any chemical reagent except for molten alkali metals. For example, in concentrated sulfuric acid, nitric
acid, hydrochloric acid, even in the aqua boil, no change in the weight and performance, almost insoluble in all solvents, only more than 300 DEG C slightly soluble in the alkane (about 0.1g/100g).
PTFE Bellow seal does not absorb moisture, does not flammable, and is very stable to oxygen and ultraviolet light, so it has excellent weatherability.
