Transcription of TYPE TSK/TLK
1 Product DescriptionJohn Crane s Metastream T series couplings incorporate scalloped, stainless-steel, flexible membranes. This design gives the most flexible solution for high-torque and misalignment conditions. This range of couplings has been specifically designed to meet the exacting standards of API 610 (ISO 13709), ISO 14691 and API 671 (ISO 10441), with coupling is available as a cartridge design to maximize reliability, and increase ease of installation on site. This concept ensures the high level of integral balance is maintained when the coupling is T series range incorporates many features listed as standard to ensure safe and trouble-free operation. This gives the user that fit-and-forget reliability expected of all John Crane s Metastream couplings. Easy to fit Meets API 610 (ISO 13709) and ISO 14691. Can be supplied to API 671 (ISO 10441), with exceptions. Intrinsic balance exceeds AGMA class 9 Ideally suited to pump applications; electric motor and turbine drives in critical process industry.
