Mechanical seal R-CARTEX(DN)

Mechanical seal R-CARTEX(DN)

The R-CARTEX double cartridge seal(DN) is a fully assembled unit for use in the oil seal chambers of pumps. With an arbitrary direction of rotation, with double hydraulic discharge-the R-CARTEX(DN) seal has proven itself perfectly in the chemical, petrochemical, pharmaceutical, sugar, food, and paper industries. The built-in valve fluid circulation system allows you to do without additional circulation devices. A shut-off fluid supply system is required.

Main characteristics of R-CARTEX(DN)

  1. Shaft diameter: d1=25-100 mm (1.000-4.000").
  2. Temperature: t=-40-220°C (-40-428°F).
