Disc couplings with ATEX certification

R+L Hydraulics has released its Lovejoy disc couplings with ATEX certification. Typical applications include pumps and compressors for use in hazardous areas, such as the petrochemical industry.

The disc couplings are suitable for rough environmental conditions. They are claimed to be wear-free and feature high torsional rigidity and zero backlash. Furthermore they can be inspected without being dismantled.

The disc couplings’ certification covers the following categories: Ex II 2 GD c 135°C (T4) and Ex I M2 c for couplings with torques up to 259kNm and Ex II 2 GD c 100°C (T5) as well as Ex I M2 c for torque values up to 4.6kNm.

There are ten versions of ATEX-certified disc couplings, covering a torque range from 0.24 to 259kNm. In addition to basic versions, various more sophisticated types with intermediate shafts or spacers are available. Specifically for use in the petrochemical industry, a series with spacer and guard ring is also available.
