Flameproof motors

We offer pressure-resistant and flameproof electric motors according to the ATEX guideline.
Kurt Maier Motor-Press GmbH distributes flameproof electric motors as formal partners of CEMP, ATB / FPM (formerly F & G), and ELPROM( Now Orange 1).
By way of our extensive warehousing in Kalefeld we are able to deliver ex stock flameproof motors in sizes IEC 63-200.
Our flameproof_ATEX motors are used in applications that require maximum safety and efficiency.

ATEX stands for ATMOSPHERES EXPLOSIVES and is the EU guideline for  flameproof devices and machines.
Kmmp is your competent partner in the field of  flameproof electric motors.
It would be a pleasure for kmmp to supply replacement motors for F & G (Felten and Guilleaume), Loher, Siemens, Dutchi, Rotor, AEG, Bartec and RAEL.

Application of flame proof motors

The flameproof motors can be used in ATEX zone 1, zone 2, zone 21 and zone 22. In Zones 1 and 2 there is a  atmospheric mixture of air and combustible gases, vapors or mists. In zones 21 and 22 there is a cloud of combustible dust in the air.

Pressure-resistant motors for use in ATEX Zone 1, Zone 2, Zone 21 and Zone 22

In zones 1 and 2, the atmosphere consists of a mixture of air and combustible gases or vapors or mist. In zones 21 and 22 is a cloud of combustible dust in the air.

Zone 1 - Gases where an explosive atmosphere is likely to form
Zone 21 - Explosive mists, where an explosive atmosphere can probably form
Zone 2 - Gases in which an explosive atmosphere can only rarely form
Zone 22 - Explosive mists in which an explosive atmosphere can only rarely form

The ATEX motors are subdivided into the following types of protection:

Ex e - increased safety, II2G Ex e IIC T3 Gb, II2G Ex eb IIC T3 Gb
Ex nA - sparkproof motor, II3G Ex nA IIC T3 Gc, II3G Ex ec IIC T3 Gc
