Supplier: EnviroPump and Seal, Inc.
Description: The main shaft in process equipment such as pumps, agitators, mixers, motors and compressors can be costly items to replace. Ordinary lip seals, commonly used on such process equipment, have both an extremely limited life and also cause considerable amount of damage to the shaft.
- Shaft O.D. or Seal I.D.: 0.6250 to 7 inch
- Sealing Element or Lip Material: Polytetrafluoroethylene (PTFE- Teflon®, etc.)
Supplier: Technetics Group
Description: Technetics Group FeltMetal® abradable material provides superior clearance control in blade tip and labyrinth seal applications up to 1400˚F [760˚C] With 30 years and over 1,000,000,000 hours of successful operation, it is no wonder that FeltMetal® Abradable Seals have been
Description: No Description Provided
- Shaft O.D. or Seal I.D.: 0.6250 to 50 inch
- Housing Bore Diameter or Seal O.D.: 55 inch
- Axial Cross Section or Thickness: 5 inch
- Sealing Element or Lip Material: Polytetrafluoroethylene (PTFE- Teflon®, etc.)
Description: Labyrinth Seals. TurboCare custom fits our Labyrinth seals to ensure a round bore and tight clearance regardless of the condition of the case. We take detailed measurements and manufacture the seals to order. TurboCare then carries out final CNC machining on-site with our portable machining centers
Supplier: NTN Bearing Corporation
Description: supplementary seals, closures, or protective devices. This design also offers the lowest possible manufacturing costs to the end user. Shielded ball bearings are protected on one or both sides by metal shields that are fastened to the outer ring. This close clearance labyrinth seal retains
- Bearing Type: Radial Ball Bearing
- Bore Size: 1.77 inch
- Outside Diameter: 3.35 inch
- Dynamic Radial Load: 7350 lbs
Description: As steam turbines age, the seals wear, causing excessive radial clearances that result in steam leakage. Worn labyrinth seals are typically and mainly caused by rubs that occur during startup due to high vibration and thermal distortion. The end result is a bowed rotor, displacing the blades

Clearance Seals and Labyrinth Seals
the radial clearance of the bearing being sealed. In addition, the operating speed and temperature must be considered when using a labyrinth seal. These seals generally do not perform well at low operating speeds. Another form of labyrinth seal is a laminar sealing ring, which uses a series of flat

Spindle labyrinth seals may include an external splashguard followed by a narrow gap, a large drainage chamber, and, space permitting, more gaps
