PUMPING RING P053
This ring is some times supplied as part of the seal design in a dual seal application.
The pumping ring is used in a dual seal convection system to assist circulation between two mechanical seals.
Either an external pumping source or this pumping ring within the mechanical seal is absolutely necessary if oil is used as a barrier fluid.
Oil’s low specific heat and poor conductivity means that it will not function well in a standard convection system. Forced circulation will be necessary and the pumping ring is a logical choice.
