Xylem Pump plug in seal, The reliability of a submersible Flygt pump or mixer will never be better than the reliability of its sealing system.Unlike dry-installed equipment, any fluid that leaks through the
seals will accumulate in the drive unit, which may be damaged. Over the long term, seal leakage will also cause numerous other problems.Exceptional demands are therefore made on every Flygt Plug-in Seal to achieve high reliability, trouble-free operation and long service intervals.
Pre-assembly in a clean environment ensures that seal faces remain protected when used in a pump repair workshop. The risk for contaminated seal faces during mounting is therefore eliminated. Mounting of single seals or relapped seals increases the risk of contaminated seal surfaces, which leads to leakage and/or excessive wear
The inner seal and outer seal cannot be replaced or refurbished separately. Since it is impossible to estimate the lifetime of an inner seal, the inner seal is automatically replaced whenever the outer seal is replaced. Once the Set is disassembled, it cannot be re-assembled in the exact same position. The remounting of separate seal rings can therefore lead to an increased leakage rate.
