Page 12: Design Details
▪ Design code to ASME VIII Div. 1 Ed. 2015 4.6 Configuration and function Design KSB quench systems are auxiliary systems for mechanical seals installed in pump sets and other rotating machinery. KSB's KWT51 quench system is used when a single mechanical seal requires a quench on the atmospheric side or a double mechanical seal requires an unpressurised buffer fluid. - Page 13 Seal chamber Drain (D) The quench liquid is contained in the reservoir of the KWT51 quench system. A rapid rise of the quench liquid fill level over a short time, visible in the sight glass of the quench system's reservoir, indicates possible mechanical seal damage. The reservoir of the quench system is made of stainless steel 316/L.
- Page 14 Replacing the quench liquid is recommended when the fill level in the sight glass of the quench reservoir has exceeded the maximum fill level. Checking the mechanical seal in addition is recommended. KWT51 14 of 30...
