Stainless Steel Discs in Factory-assembled Cartridge for Medium-duty Applications

John Crane’s Metastream T Series metallic membrane couplings, incorporate scalloped, stainless-steel, flexible membranes.  This design gives the most flexible solution for high-torque and misalignment conditions.  The range of TSK/TSC has been specifically designed to meet the exacting standards of API 610 (ISO 13709) and ISO 14691.  With an excellent power to weight ratio and fit-and-forget reliability, the TSK/TSC coupling is ideally suited to meet the pumping, motor, and turbine drive power transmission in oil and gas, petrochemical, power generation, and other critical process industries.
