R+L Hydraulics GmbH, producers and distributors of hydraulic accessories and couplings headquartered in Germany, presents ATEX certified couplings for applications in hazardous areas including gear and disc couplings. A wide range of variants of these coupling types is offered, suitable for various potentially explosive atmosphere applications.
Disc couplings with ATEX certification are used in pumps and compressors for hazardous areas, for example in the petrochemical industry. The disc couplings are designed to be robust to withstand harsh environmental conditions. There are ten series available, covering a torque range from 0.24 kilonewton meter (kNm) to 259 kNm. Aside from the basic designs, different variants with intermediate shafts or spacers are offered. Made especially for use in the petrochemical industry, there is a series available with an intermediate piece and protective ring, also meeting the requirements of the API 610 norm.
Typical applications for gear couplings with ATEX certification are for example pumps, breakers, mixers, presses, steelworks and conveyors. This robust coupling type is recognised for a high performance and simple maintenance. The availability of gear couplings for hazardous areas covers torque values ranging from 0.3 kNm to 5340 kNm. The gear couplings are available in 27 different series, including variants with a flanged or continuous sleeve, with special gaskets as well as with intermediary shaft or spacers.
