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.

A SERIES CLOSE-COUPLED ARRANGEMENT
Close-coupled Wrap-fit Urethane Element Coupling
Close-coupled Wrap-fit Urethane Element Coupling
The A Series is the simplest construction of all our couplings. The arrangement consists of two close-coupled hubs which have six or eight teeth, depending on size. These components are made of quality carbon steel. The split insert, which is made of specially compounded urethane, fits over the hub teeth. The retaining ring is made of steel and is located with two setscrews.
A SERIES SPACER ARRANGEMENT
Wrap-fit Urethane Element Coupling
Wrap-fit Urethane Element Coupling
John Crane A Series couplings provide a solution to one of the most persistent and troublesome problems facing maintenance personnel: periodic coupling failure and the downtime and expenses that go with it. If a new insert is needed, a replacement can be installed in minutes, without moving either the prime mover or the driven equipment.
C SERIES
Rigid Coupling with Radially Located Parts for Vertical Applications
Rigid Coupling with Radially Located Parts for Vertical Applications
C series rigid couplings incorporate a segmented, piloted locating design. This eliminates the shaft distortion associated with conventional ‘clam shell’ coupling designs where the motor shaft supports the pump shaft, and there are no bearings in the pump. It can also be used in vertical mixer applications, where the same characteristics are required.
L SERIES
General-purpose All-metal Membrane Coupling
