TEFLON BELLOW SEALS – RTB

Teflon Bellow seals are designed for handling acids. It is unrivaled in its ability to withstand corrosive fluids and is highly resistant to oxidizing and reducing agents. That’s because it is made out of chemically inert materials like PTFE, GFT, Ceramic, Carbon, Silicon Carbide, Hastelloy ‘C’ which come in contact with the acids during the operation and perform reliably under all even extreme corrosive conditions.

The hydraulically balanced and flexible bellow accommodate shaft run-out and seal hang-up. These seals are also compactly designed for easy installation and virtually nil maintenance. The multiple springs with bellow provide uniform pressure all over the seal face to ensure effective sealing.
