Cartridge Seal

A self contained sealing assembly consisting of:
  • The complete mechanical seal
  • The seal gland
  • A seal sleeve
  • A device (usually clips) to hold, center, and position all of the components

A stationary version of the cartridge seal is shown in this illustration.

A cartridge seal is necessary if you intend to make impeller adjustments with end suction centrifugal pumps.
