Technical Specifications and Design Features
Material Composition
The FS-QL60 Flygt Pump Seal is engineered with a careful selection of materials to ensure optimal performance and longevity. The primary components of the seal, including the rotating and stationary faces, are typically made from silicon carbide or tungsten carbide. These materials are chosen for their exceptional hardness and wear resistance, crucial for withstanding the abrasive nature of many pumped fluids. The elastomeric components of the seal, such as O-rings and bellows, are often made from materials like Viton or EPDM, selected for their chemical resistance and ability to maintain flexibility over a wide temperature range. This careful material selection allows the FS-QL60 to maintain its sealing effectiveness in diverse operating conditions, from highly acidic or alkaline environments to those with high concentrations of suspended solids. The seal's design also incorporates anti-clogging features, which is particularly important in wastewater applications where debris can interfere with seal performance.
Seal Face Technology
The heart of the FS-QL60 Flygt Pump Seal lies in its advanced seal face technology. The seal faces are precision-lapped to create an ultra-flat surface, ensuring optimal contact and minimal leakage. This flatness, often measured in light bands, is crucial for maintaining a thin fluid film between the faces, which provides lubrication and prevents dry running. The seal face design incorporates hydrodynamic features that create a pumping action during operation, helping to circulate cool, clean fluid across the seal faces and dissipate heat. This self-cleaning action is particularly beneficial in applications where the pumped media contains abrasive particles. Additionally, the FS-QL60 may incorporate balanced seal designs, which help to maintain consistent face pressure regardless of fluctuations in pump pressure. This balance ensures that the seal remains effective across a wide range of operating conditions, from startup to full load, contributing to its versatility across different Flygt pump models like the 4670 & 4680 and 7045.
Installation and Maintenance Considerations
The FS-QL60 Flygt Pump Seal is designed with ease of installation and maintenance in mind, recognizing the critical nature of minimizing downtime in pumping operations. The seal typically comes as a pre-assembled cartridge unit, which simplifies the installation process and reduces the risk of assembly errors. This cartridge design allows for quick replacement during routine maintenance, minimizing the time the pump is out of service. The seal's compatibility with various Flygt pump models, including the 600 motor unit and 7055.600 pump, ensures a standardized approach to maintenance across a fleet of pumps. Regular maintenance of the FS-QL60 involves inspection for wear, checking for proper alignment, and ensuring that the seal flush system (if present) is functioning correctly. The seal's robust design often allows for extended periods between maintenance intervals, but the specific schedule should be determined based on the operating conditions and the criticality of the application. Proper installation and maintenance of the FS-QL60 are crucial for maximizing its lifespan and ensuring the continued efficient operation of the Flygt pump.
