Features

Quench fluid supply systems are used with single mechanical seals. They act as a convenient fluid reservoir. The QFT6000A4 stainless steel tank is equipped with a sight-glass for monitoring the MIN/MAX filling level and can be fastened with a lug fixture.

Advantages

  • Sight-glass for MIN/MAX monitoring has a large indicator area
  • Filling is possible by 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

Standards and approvals

  • API 682 / ISO 21049
  • API 682 4th ed. Cat. 2/3 - 1CW-FL

Functional description

Quench fluid systems (Plan 51) are employed to:

- Absorb leakage
- Monitor the leakage rate (e.g., through periodic reading of the level in the tank)
- Prevent icing
- Protect against dry running
- Stabilize the lubricating film
- Exclude air from the media in order to prevent a reaction with oxygen in the air
