Line Shafts FOR USE IN
HAZARDOUS AREAS AND EXPLOSIVE ATMOSPHERE

   

Design of the Servomax EX:
No dimensional change of the EK standard series. The material of the hubs and the inserts will change.

Hubs:
In general steel or stainless steel hubs with be used Caution: Aluminum hubs may not be used in explo sive enviroment.

Elastomer insert:
A special elastomer insert (Type D/92 Sh A), which is able to conduct electricity is used. This prevents the possibility of electrostatic loads and sparks.

Mounting, Sizing:
All misalignment values and the transmittable torques are reduced by 30%.

Maintanance:
A routine inspection of the coupling must be performed.

Mounting
manuals: Mounting and maintanance manuals are provided with every EEx coupling.

ATmosphere EXplosible

The ATEX 95 / ATEX 137 is regulated by the new European directive. Generally the explosive atmosphere is classified in 3 different zones.

Zone 0:
A place in which an explosive atmosphere is consisting out of a mixture of air and flammable substances in the form of gas, vapor or mist is present frequently, continuously or for longer periods

Zone 20:
Is relevant for an explosive atmosphere in the form of clouds of combustible dust in air under the same conditions as above.

Zone 1:
Described as a place in which an explosive atmosphere is existing of a mixture of air and flammable substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally.

Zone 21:
Is relevant for an explosive atmosphere in the form of clouds of combustible dust in air under the same conditions as above.

Zone 2:
A Place in which an explosive atmosphere is consisting out of mixture with air of flammable substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, it will persist for a short period only.

Zone 22:
Relevant for an explosive atmosphere in the form of a cloud of combustible dust in air under the same conditions as above.

For the classified zones 1/21 and 2/22 the Servomax servo-insertcoupling do have an accreditation according to ATEX 95a
