Equipment group: II – all other explosive areas than mines;
Category group: 2 – high level of protection (can be used in zone 1);
Atmosphere: G – gas;
Explosion group: IIC – gas group (such as acetylene, hydrogen);
Temperature class: T4 – in the event of a malfunction, the maximum temperature of a
surface that may be exposed to gas T4 = 135°C ;
Earth connection of the pump and other equipment
Connect a suitable earth wire to the stainless steel earth connection that is placed on the inside
of one of the pump housings. Connect the other end of the earth wire to earth and also make
sure that other equipment like hoses/pipes/containers etc. are properly earthed/connected.
Dry run in ATEX pump
ATEX approved pumps can run dry without increasing the risk of creating potential ignition
sources. Nevertheless, dry run periods should be decreased to minimum as they increase the
wear of parts inside of the pump.
Centerblock temperature control
In ATEX applications it is essential to monitor the centerblock temperature. In case of failure
the temperature can rise and the pump has to be stopped immediately.
Gearmotor maintenance intervals
The ATEX rated gearmotors have to undergo a general overhaul based on the below
maintenance intervals:
Pump size Motor power Maintenance interval

0.55 kW; 0.75 kW 40.000 hours
0.25 kW 14.500 hours
TE100/120/125

1.8.3. Electrical safety
Do not carry out any maintenance or/and operation on the pump while it is running or before
it has been disconnected from the power supply. Avoid any danger caused by electric power
(for details see current regulations in force). Check that electrical specifications on the data
plate are equivalent to the power supply to which it will be connected.
1.8.4. Chemical hazard
Whenever the pump is to be used for pumping a different liquid, it is essential to clean the
pump beforehand in order to avoid any possible reaction between the two products.
