The complex application of a powerful vacuum pump required the use of a high-precision and backlash-free shrink disc. The challenging transmission torque and the minimum installation dimensions were specified by the customer. Furthermore, the pump gear was to be directly connected to the shrink disc by flange mounting. Specially for this purpose, RINGFEDER® has designed a special shrink disc that meets the requirements posed also with regard to the continuous series application, and which establishes a stable frictional connection to the drive shaft.
Pump rotors of any size and shape must be aligned towards each other with exact precision. For this purpose, the extensive RINGFEDER® standard range offers high-performance locking device solutions in two-piece and three-piece variants. Furthermore, the users are provided with a choice of complete, separated, and half shrink discs depending on the demand and requirement. For the use in small to medium-sized pumps, premium-quality RINGFEDER® locking elements are perfectly suited. For more critical applications, e.g. in large-scale facilities of the chemical sector and the oil industry, special variants with a suitable surface protection or special materials are designed. Compliance of all RINGFEDER® solutions with industry-specific regulations and standards goes without saying. Complemented by the versatile portfolio of consistent and durable shaft couplings, RINGFEDER® is the outstanding system partner for users from the pump sector.
