VRB3/VBRB3-Welded

ANSI Rotating Welded Metal Bellows Single Cartridge Seal

VRB3/VBRB3 Features

• Rotating design uses centrifugal force for self-cleaning
• Uniform 360° transfer of torque to the rotating face
• Welded metal bellows replace the dynamic elastomer which can hang up the seal faces
• No springs to clog or break
• No fretting
• Only three (3) static elastomers – eliminate seal failures caused by dynamic O-ring “hang up” and offers cost savings when upgrading to Perfluorelastomers.

Operating Parameters

Note: Maximum temperature/speed/pressure/runout indicates operating extremes independently and does not imply the seal will function at these extremes at the same time.
