Flexible Membrane Couplings produced by “NASOSTECHCOMPLECT” is designed for energy transfer form driver to driven machine within the stipulated alignment of their shafts. The up-to-date methods of strength analysis and designing, careful manufacturing study, long-term experience of manufacturing and exploitation result in development of reliable flexible membrane couplings which allow:- to reduce vibration and noise of the operating unit;- to increase life time of bearings and end seals of pumps and compressors;- to refuse lubrication and maintenance;- no-failure operation within the unit life time.Possible applications for the flexible membrane couplings produced by “NASOSTECHCOMPLECT” is oil-producing and oil-refining industries, chemical industry, energy production industry, iron and steel industry, conveyors, hoisting equipment, cement industry etc. Available range of transfer power is from 5 kW up to 8000 kW.
