A Belleville Stack Spring is from a series of conical disc-shaped washers, each having a slightly curved shape. The washers are stacked together in a specific arrangement, with one washer nested inside the other. It is positioned within the pump assembly to apply the necessary force in either the axial or radial direction, depending on the specific application.Attributes:• Helps minimize vibration and noise generated by loose or excessive clearances• Manufactured to precise specifications and is built for durability and reliabilityApplications:A Belleville Stack Spring provides controlled axial or radial force to maintain proper axial or radial clearances within the pump. It exhibits unique mechanical properties and functions as a highly efficient spring when compressed.
