Series : R21 & R21 & MO21

The PTFE is such a magic material among all plastic, which consist of high anti thermal and anti corrosive characteristics. The PTFE is chemically inert material.

We have designed the R21, MO21and S21 PTFE bellow/TEFLON bellow mechanical seals. This series is specially designed for the extremely corrosive chemicals like concentrated acids and salts, chemically active organic compounds and strong oxidizing and reducing agents.

The metallic components like clamping ring and springs are located outside the pump stuffing box. The PTFE bellow seals used to seal the metallic components.

The seals can be customizing as per requirement of the client.
