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.
Function The quench system is an auxiliary system for single mechanical seals and double
mechanical seals. Single seals combined with API Plan 51 operating mode are used
with a quench liquid. The quench liquid prevents any ice from forming on the
atmospheric side of the single seal or on the atmospheric side of the inboard
mechanical seal. In the case of dissolved salts, crystallisation of the fluid handled is
prevented on the atmospheric side of the single seal. In the operating mode to API
Plan 51 and API Plan 52 the quench liquid / buffer fluid prevents the fluid handled
from coming into contact with air. Another function is the absorption of mechanical
seal leakage. The fluid handled is prevented from coming into contact with oxygen
or humidity in the air. In the operating mode to API Plan 52 the quench liquid is used
as unpressurised buffer fluid for a double mechanical seal.
