The MA250 is a new generation compact cartridge seal designed and manufactured with the latest state-of-the-art technology.

The seal is supplied as a ready to install arrangement thereby ending the industry's search of off the shelf seal requirements.

  • Can be installed in narrow stuffing boxes in pumps as per ISO 3069 and DIN 24960. The seal arrangement does not warrant any modification even in case of conversion from gland packings.
  • The flexible element is stationary and is isolated from shaft vibrations, thus there is no shaft wear and seal can be used for higher speeds.
  • Spring and drive mechanism are on the atmosphere side of the seal eliminating clogging of springs and wear of drive pins.
  • For abrasive liquids both hard faces are used.
