Supply of mechnical seal in accordance with API 682 / ISO 21049, Plan 51.

Advantages

  • Sight-glass for MIN/MAX monitoring has a large indicator area
  • Filling is possible via a filling filter or a separate pipe connection
  • Combined filling and ventilation filter in the quench fluid tank for reliable operation
  • Tank made of 1.4571: high resistance to corrosive media

Functional description

Quench fluid systems (Plan 51) are employed:
  • to absorb leakage
  • to monitor the leakage rate (e.g. through periodic reading of the level in the tank)
  • to prevent icing
  • to protect against dry running
  • to stabilize the lubricating film
  • to exclude air from the media in order to prevent a reaction with oxygen in the air
