TA KO . \f?.y - - Sales Information Bulletin No. 80 DATE: APRIL 25, 1972 SUBJECT: MECHANICAL SEAL PROBLEMS IN HIGH TEMPERATURE HEAT TRANSFER SYSTEMS Attached is a recent bulletin directed at mechanical seal problems in heating systems. . We have experienced a number of mechanical seal problems . in Therminol systems over the years that could have been avoided had a better understanding of conditions leading to seal failure been known. The attachment is not an all-inclusive listing of problems that create a poor seal environment, but attempts to point out several of the more obvious conditions that could con tribute to poor seal performance. We are sometimes oblivious of the consequences of seal fail ure -- it can cause unprofitable interruption of production, create a vapor and fume hazard, contribute to environmental pollution and cast doubt on the use of the heat transfer fluid. Proper education of customers on the potential problems of and preventative maintenance for mechanical seal installations can result in greater satisfaction with the Therminol system. A study of the attachment should enhance your expertise of mechanical seals in Therminol service. Should you encounter a seal problem and need assistance, con tact the local seal supplier or the Therminol product specialist. D. E. Roush DSW 326160 Monsanto AD-769 STLCOPCB4075849
