John Crane’s Metastream® M Series couplings are designed with features to increase the safety, reliability, productivity and profitability of your plant. These couplings meet the requirements of API 610 as standard and are suitable for any market or application where you need a diaphragm coupling. Metastream diaphragm couplings are a multiple membrane (disc) straight diaphragm design. Like all diaphragm couplings, it disconnects the drive from the driven machine in the event of a torque overload or excessive misalignment that causes the diaphragm to fail. The pre-assembled pack that includes the Metastream diaphragm design also includes a safety device that in the event of a diaphragm failure allows the equipment to be shut down safety while helping to prevent extra damage. Due to the pre-assembled pack(s), any damaged diaphragm can be easily and quickly replaced.
Applications Include: Centrifugal Pumps, Potable Water Pumps, Pipeline Compression Machinery
