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
