Circumferential Seals

Circumferential seals are designed to minimize the leakage of fluid or gases by either sealing directly against the shaft or by using a closely controlled clearance with the rotating shaft or other moving parts which creates an energy efficient seal.  Circumferential seals also have a longer lifespan and require less maintenance compared to traditional mechanical seals.

 

Non-contacting Mechanical Seals

Seal Types

Windback Seal

Windback

When working with “oil-free” rotary screw compressors or any other oil-free rotary machines, our windback seals are ideal.

FEATURES

  • Zero power dissipation
  • Windback seal utilizes shaft boundary layer to seal process oil or gas.
  • Gas purge option.
  • Typical uses include vacuum pumps, blowers, compressors, and other rotating equipment
seal-carbon_solid

Carbon Solid

Carbon solid seals are an ideal long-term solution for a variety of applications and industries. 

FEATURES

  • Retainer utilized for axial sealing inside the groove.
  • Non-contacting, segmented,self-aligning carbon rings for controlled leakage.
  • Face load 50-75% less than spring seal
  • Short axial length
  • Reduced friction on seal face lowers heat and wear resulting in longer seal lifespan

PARAMETERS

  • Pressure: Vacuum to +290 psi abs
  • Temperature: -184 ̊F to +400 ̊F
carbon-split

Carbon Split

The carbon split seal, which splits into two halves for easier replacement, is an easy-to-install, long-term solution for a number of industries. 

FEATURES

  • Retainer utilized for axial sealing inside the groove.
  • Split housing for easy installation
  • Non-contacting, segmented, self-aligning carbon rings for controlled leakage.

Parameters

  • Pressure: Vacuum to +290 psi abs
  • Temperature: -184˚ F to +400˚ F
  • Speed
seal-Carbon_Floating

Carbon Floating

Our carbon floating seals are a dependable option in instances when mechanical seals reach their limits.

FEATURES
