Key product characteristics and benefits

  • Raceway- Sealing grooves, machined into the face of the raceway, match the impeller sealing grooves, minimizing water slippage and increasing delivery efficiencies.
  • Impeller- Annular grooves or sealing rings, machined into the face of the impeller are perfectly matched with corresponding grooves in the raceway and intermesh without metal-to-metal contact to form a labyrinth seal.
  • Extended Life- Lok(R) adjustment allows for extendeded life, field adjustment, and restoring factor efficiency as hydraulic passage wears.


Customize this product with the following features and materials:

  • MJ Jacketed Seal – Special seal arrangement effectively handles fluids up to 500° F and eliminates seal cracking and distortion, substantially extending seal life.
