HRC-N seal
HRC-N seal

Features mechanical seal hrc-n

  • Cartridge
  • Balanced
  • Independent of direction of rotation
  • Stationary multiple springs
  • Spring protection sleeve
  • Variant for operation with pressureless quench available (HRC2000N)
  • Dual seal with and without pumping screw (HRC3300NF, HRC3300N) available

Advantages mechanical seal hrc-n

  • Insensitive to solids containing media. Solids content 40 % (single seal), 60 % (double seal)
  • Springs protected from product and leakage
  • Variant with short installation length to meet limited space conditions (HRC1100N)
  • Dual seal remains closed in case of barrier pressure failure, self-closing at pressure reversal (HRC3300NF)
  • Operation under vacuum without seat locking possible
  • No damage of the shaft by dynamically loaded O-Ring
  • Insensitive to shaft deflections due to stationary design
