Product Description

Disc coupling for torque transmission., , PWH:, Powerflex High Performance couplings have an innovative design that bring high reliability for transmissions in rotary machines., They are projected to comply with most requirements of the API 671 standard, with respect to assembly. Hubs, guard rings and spacers are manufactured with high alloy steels, while flexible elements are made with high grade stainless steel and the fixture parts undergo rigourous quality control., As a result of controlled assembly, interference pilot guide and screws with controlled tolerance insure the balancing integrity even after many assemblies., The flexible coupling must handle two functions: (1) Transmit drive torque to the driven machine and (2) accommodate misalignment of the axles., High Performance Powerflex couplings are specifically designed to handle these tasks required in critical actions such as: compressors, feeding pumps, injection pumps, generators, gas and vapor turbines and API 671 applications., , , PWE:, PWE couplings are designed for medium power service, with a high level of reliability in the transmission of rotating equipment and with the use of spacers. PWE couplings were specifically designed to meet API 610 specifications and they also meet most of the API 671 specifications., It consists of three main parts, two cubes and one flexible center unit assembled in the factory that is installed and removed as a unitized component, simplifying the installation and maintenance., The central unit is piloted which ensures excellent dynamic balancing standards; AGMA class 9 is the factory standard. The AGMA balance Class 10 and 11 or ISO 2.5 and 1.0 are available options., An anti-flail safety device is also included in the assembly of the flexible central unit.
