FT-71
FT-71 Seal are externally mounted Teflon bellow seal. It is mainly use to handle at corrosive media. Because the design of this seal elements the contact between metal parts of the seal and corrosive liquid which it handles. The seal contain PTFE + GFT composite bellows which is hydraulically balanced and is machined with high precision to form the prescribed contour.

Salient Features
• Such type of seal does not affect on shaft or any other damage.
• No dynamic elastomer.
• Low maintenance.
• It has replaceable faces.
FT-75
FT-75 Incorporate secondary seals that move axially along a shaft or sleeve to maintain contact at the seal faces. The seal faces are loosely inserted and can be easily ex-changed. The rotary face is shrink fitted in metal shell thereby giving additional advantage of offering both hard faces. Springs are fully immersed in the process fluid, hence do not get clogged because of the centrifugal forces.

FT-81
FT-81 Seals are designed to handle clear liquids under normal PV condition. This type of seal do not require step on the shafts for installation, due to which, this are preferred choice for double tandem arrangements with external seal support systems & device. These seal required lower stuffing box for installation. These types of seals are used in Petrochemicals, Petroleum Refinery, Solvents, Hydrocarbons & General Industrial fluids.
