Catalog excerpts
Chemineer™ ChemSeal™ Top Entering Mixer Seal ChemSeal is a true Chemineer mixer seal designed for demanding top entry agitator applications. Safe and Reliable Operation • Double balanced seal design keeps seal faces closed during a pressure reversal caused by process upset or failure of barrier system, preventing seal failure, containing vessel contents, and improving operator and plant safety • Permanently installed above the tank drop collar design securely holds the shaft during seal change and improves operator safety by eliminating “on the fly” installation of shaft support, prevents the shaft from falling into the vessel, and eliminates the need for vessel entry or overhead cranes to support the shaft Simple Maintenance and Fast Replacement • Industry leading swing-out seal change out procedure with drop collar is simple and can be completed in 30 to 60 minutes, providing increased process uptime • True cartridge design allows for removal, inspection and replacement of worn seals quickly and easily • Mixer seal design and heavy duty gearbox bearings eliminate need for a seal bearing and associated installation and maintenance costs • Provision for jacking screws and setting clips storage is provided to aid in seal removal and future setting of the seal Application Versatility • Bidirectional rotation enhances process and operational flexibility • Designed for a wide range of agitator models to allow ChemSeal to be the common plant standard • Throttle bushing option is available for clean flush below seal • Debris well option available to eliminate process contamination Superior Performance • Available in either single or double configurations, the ChemSeal provides outstanding seal performance and safety • ChemSeal is designed specifically for agitator duties where shaft movements are larger, speeds are slower and conditions more variable than those encountered by pump seals • Balanced seal design reduces seal face wear rate and increases the pressure capability by reducing the seal contact pressure as the process pressure fluctuates • Dual sleeve to shaft o-rings with heavy cross sections make the seals more tolerant of shaft deflections inherent in agitator applications Troubleshooting and Replacement Parts Assistance • Our service center is available 24 hours a day to diagnose and correct sealing problems • Factory trained technicians available for in-plant help with installation, operation and maintenance questions • Replacement parts are readily available to increase uptime and reduce customer inventory requirements
