Тип контркольца

Single mechanical seal R-HRN

Applied for the following pumps: Alfa Laval, Ebara Lowara, KSB (Etanorm, Etachrom), WILO (MVI, MHI, IPL), Grundfos (CDM), Saer (IP), Calpeda (GM, MXS), Hecker HN 410SU.

The analogues: Burgmann HRN, Roten EHS3 seal

Advantages

  • Safe exploitation (nondestructive) due to the fixation of rotary ring from crank by four-sided nail.
  • The springs are isolated from fluid and it prevents from sticking and obstruction.
  • It is suited for pressure reverse.
  • It possible to use in vacuum without additional fixation of counter ring.
  • The shaft damages are excluded due to the absence of the dynamic ring of round cross-section on the shaft.
  • Compact design
  • Perfectly match for retooling as it doesn’t require corrective maintenance of the pump
  • It suitable for medium with solid particles and for abrasive medium
  • The noncompensated construction has its advantages even for the smooth shaft
  • Non-reactive for the misalignments of shafts due to the stationary design

Commend range of use

  • Pulp and paper industry
  • Waterworks and effluents treatment systems
  • Mediums that includes contaminants, solid particles, abrasives
  • Volatile hydrocarbons (not API seals)
  • Clammy, viscous mediums
  • Standard chemical pumps
  • Canalization pumps
