Mechanical seal, shaft 25 to 120 mm, pressure to 25 bar.

SHAFT
25 to 120 mm
PRESSURE
to 25 bar
TEMPERATURE
-40 to +220 °C
FACES
Silicon carbide against silicon carbide

Why it is specified

Identification is most of the job. A pump serial or a photograph of the nameplate is usually enough to name the seal, the wear rings and the gasket set, so the order does not wait for a drawing nobody can find.

Typical applications

  • Aggressive media where leakage is unacceptable
  • Agitator shaft sealing
  • Centrifugal pump repair
  • Hygienic process equipment

Options and executions

  • FFKM secondary seals for aggressive media
  • Matched spare face set with the order
  • Quench and drain connections
  • Setting clips retained for re-fitting
