Teflon Bellow Mechanical Seals Suppliers

Teflon Bellow Non-Pusher Mechanical Seals are bellow unit made up of Teflon material of pure Teflon, Glass filled Teflon (GFT), Carbon filled Teflon (CFT). In Teflon bellow Non-pusher seal O-Ring is absent, Instead of O-Ring Teflon Below provide sealing. It consists of a bellows assembly including Helical Multi spring. The Teflon bellow is a component that acts as sealing element (like an ‘O’ ring in a pusher type).

The bellows prevents any leakage to the atmospheric side of the seal, and has a large clearance between itself and the shaft or sleeve, it can move freely in the axial direction (no dynamic ‘O’ ring), reducing the potential for hang up. Elastomer Bellow Non-pusher Mechanical Seals can be used from Low temperature to high temperature depending of nature of fluid.
