혜택

  • Double cartridge seal, specially developed for dry-installed pumps of the Amarex KRT type series that are fitted with a cooling jacket with coolant circulation.
  • An impeller integrated between the seal at the impeller end and the seal at the motor end ensures the best possible circulation of the cooling liquid.
  • The special seal design facilitates installation without assembly fixtures or adjusting dimension, ensuring optimal pre-loading of the mechanical seal and low wear.
