L Series

Features
• Fit and forget: The L Series coupling is designed for infinite life and with correct machinery alignment will out last the machines it connects.
• Overload protection: The coupling is fitted with overload collars to prevent membrane rupture in the event of severe torsional overload.
• Low imposed loads: The membranes have been designed to optimize their torque capability, whilst minimizing the reaction forces due to misalignment, thus maximizing the life of the machines connected.
• Zero maintenance: The all-metal construction has no relative moving parts, and hence requires no lubrication or routine maintenance increasing reliability.
• No backlash: The coupling design, with fitted bolts, and torsionally stiff membranes ensures that there is zero backlash. This makes the coupling ideal for drives where constant speed is crucial.
• Spark-resistant option. Hazardous areas require spark-resistant couplings. This is achieved by replacing the overload collars with components manufactured from non-ferrous metals
Recommended applications
• Process Pumps
• Mixer and Agitators
• Electric Motors
• Gearboxes
• Steam Turbines
• Other Compressors
• Driven Machinery
• Other Rotating Equipment
• Generators
METASTREAM® brand L series range of membrane couplings has been specifically designed to provide a cost-effective solution for demanding industrial applications. The couplings are selected by their torque capacity, with the scalloped hub providing the right size for the shaft.
