Extending Seal Life with Bi-Directional Mechanical Seal Pumping Rings.

Plan 23 offers improved vapor pressure margin in the seal chamber to extend seal reliability. The reduced working temperature of the seal from Plan 23 operation prevents coking on the atmospheric side of many mechanical seals in hydrocarbon services, which again enhances seal life. These are all positive impacts on pump MTBF – and on corporate profits.
