Mechanical Seals Blog"We seek to serve as the voice of all mechanical seal manufacturers, representing our collective interest to organizations responsible for the development of standards and regulations governing the design, application, and operation of mechanical seals. We also seek to enhance performance of mechanical seals by providing educational programs demonstrating best practices to achieve optimal performance. We will use this blog area to provide awareness to all stakeholders in the mechanical seal industry as to our activities and areas of focus."
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.
