Features

Quench fluid supply systems are used to supply single or tandem mechanical seals. They act as a convenient fluid reservoir. The exchange of fluid takes place by the thermosiphon principle or by forced circulation, e.g. with a pumping screw. The QFT2000 stainless steel tank is equipped with sight-glasses for monitoring the MIN/MAX level and can be fastened with a lug fixture. The leakage overflow can be selectively discharged.

Supply of mechanical seal based on API 682 / ISO 21049, Plan 51.

Advantages

  • Available in a range of different material combinations: suitable for a wide range of demanding operating conditions
  • Design for medium temperatures of up to +200 °C (+392 °F)
  • Tank made of 1.4571: high resistance to corrosive media
  • Integrated overflow for selective discharge of leakage
  • Instead of the sight-glass it is possible to use a level switch to monitor the fluid volume
  • Combined filling and ventilation filter in the quench fluid tank for reliable operation

Recommended applications

  • Chemical industry
  • Food and beverage industry
  • Pharmaceutical industry

Functional description

Quench fluid systems are employed:

  • to absorb leakage
  • to monitor the leakage rate (e.g. through periodic reading of the level in the tank)
  • to lubricate and to cool the outboard mechanical seal in a tandem arrangement
  • 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
