Versatile Mechanical Seal

The ED560 is a dual seal in a back-to-back arrangement with an EA560 base. Therefore, the seal combines the advantages of the EA560 with the advantages of a dual seal.


  • Dual seal
  • Good chemical resistance and ability to handle solids
  • In-house manufactured sliding parts
