PS-SEAL® PTFE Rotating Shaft Seals

PS-SEAL PTFE rotating shaft seals excel under high pressure and in extreme vacuum.

PS-SEAL® PTFE Rotating Shaft Seals give you best-in-class sealing performance for a wide range of high-speed and extreme pressure conditions.

Where others fail, PS-SEAL® reliably seals rotating shafts at high circumferential speeds, high pressures, and extreme temperatures. PS-SEAL®'s excellent chemical resistance makes it well suited for food and pharma applications, including those where FDA approval is required.

Available in a wide variety of standard or custom styles and materials, the PS-SEAL® utilizes high-performance GYLON® modified PTFE to maintain contact between the seal and shaft. The result is a seal that can withstand pressures up to 50 times that of standard lip seals, surface speeds up to 45 m/s, and temperatures up to 500º F (260ºC), in both dry and abrasive environments.

The portfolio of Garlock PS-SEAL®s includes standard, non-standard, and special customized seals.

Introducing the PS-SEAL® by Garlock

Where is PS-SEAL® Used?

The PS-SEAL®, leveraging GYLON® material, is essential for sealing rotating shafts under challenging conditions such as high speeds, pressures, and temperatures from -130˚F to 500˚F. It's optimally used in equipment like Pumps, Agitators, Mills, Grinders, Mixers, Dryers, and Screw Conveyors, where traditional seals falter. Additionally, it enhances the reliability of Dosing Systems, Decanters, Separators, and Gearboxes by preventing leaks and contamination. Its robust performance and compatibility with FDA standards make it ideal for the food and pharmaceutical industries, demonstrating its wide-ranging applicability and effectiveness in various demanding industrial environments.
