Mechanical Seals Blog"In alignment with the overall mission of the FSA, its Mechanical Seal Division seeks to be recognized by customers, regulatory bodies, and FSA member companies as the primary source of technical information for sealing solutions and their application in all matters relating to standards and education. Through our efforts, we will enhance the reliability and effectivity of this critical technology."
Controlling the Seal Chamber Environment
Reducing the temperature in the seal chamber offers many benefits to the performance and reliability of a mechanical seal operating in hot service. This is one of the most effective ways to increase the vapor pressure margin and prevent the pumped fluid form flashing in the seal chamber or at the interface of the mechanical seal’s faces. Additionally lowering the seal chamber temperature also increases the fluid’s viscosity, providing a more stable fluid film at the interface of the seal faces.
One method of achieving a reduction in temperature is to circulate fluid form the seal chamber through a heat exchanger and return the cooled fluid back into the seal chamber. The heat exchanger is often referred to as a “seal cooler” since it is not part of the process, but just an auxiliary system component.
