Production of Scientific Production EnterpriseâNasostechcomplectâ is flexible membrane couplings. They are usedfor connection with drive of rotating shafts of different machinesâ pumps, compressors, fans, i.e.Flexible membrane couplings provide effectivecompensation of all typesâ relative displacement (de-centering) ofconnectable shafts. Compensation principle provides, in comparisonwith tooth-type and bush-finger couplings, multiple decrease ofradial and axial load on supports. Consequently â significantincrease of reliability and recourse of unit, decrease of noise andvibration.Â
