2.6 ATEX approvals
2.6.1 Scope of ATEX categories for NB, NBG, TP, TPD pumps
The link between groups, categories and zones is
explained in the 2014/34/EU Directive. Please note
that this is a minimum directive. Some EU countries
might therefore have stricter local rules. The user or
installer is always responsible for checking that the
group and category of the pump correspond to the
zone classification of the installation site.

WARNING
Accumulation of explosive gases from
shaft seal leakage
Death or serious personal injury
- Provide adequate ventilation around the
pump if the pump is installed in a pit. A
minimum air exchange of 1.5 times per
hour is required.
CAUTION
Overheating
Minor or moderate personal injury
- The pump must not run against a closed
outlet valve or a closed shut-off element
as this may cause overheating. Install a
bypass with a pressure relief valve.
DANGER
Electric shock
Death or serious personal injury
- The pump housing must be earthed.
DANGER
Ignition of explosive environment
Death or serious personal injury
- The pump housing must be earthed.
Remove coating from the earthing point to
ensure proper grounding connection.

5. Starting up the product
5.1 Before starting an ATEX-approved
pump
1. Compare the order with the supplied pump and
motor. Check that the EPL of the pump and motor
(Equipment Protection Level) corresponds to
what is ordered. If the EPL of the motor and
pump differs from each other or the temperature
class of the motor differs from that of the pump,
the following applies:
– The EPL which defines the lower protection
level applies. Example: The EPL of the motor
is Gc and the pump’s is Gb. Gc applies.
– The temperature class which defines the
higher temperature applies.
Example 1: Motor temperature class is T4 (135
°C), and pump temperature class is T3 (200
°C). T3 (200 °C) applies.
Example 2: Motor temperature class is T3 (200
°C), and pump temperature class is T4...T3.
T3 (200 °C) applies.
2. Check that the pumped liquid and its operating
temperatures are in accordance with what is
stated on the "key application data sheet".
3. Check that the shaft seal and rubber parts of the
pump are as ordered. See the nameplate.
Fig. 7 Example of code for rubber parts on the
NB, NBG nameplate
Fig. 8 Example of code for rubber parts on the
TP nameplate
The key to the nameplate is shown in the installation
and operating instructions for the standard pump.
4. Check that the maximum speed on the pump
nameplate corresponds to the speed of the motor
and that the pump will not be used for operation
with a frequency over 60 Hz.
5. Check that the pump has been filled with liquid
and is vented.
Fig. 9 Location of vent screws
6. Check that the shaft can rotate freely. There must
be no mechanical contact between impeller and
pump housing.
7. Check the direction of rotation. The correct
direction of rotation is shown by an arrow on the
pump housing.
8. Before start and during operation, make sure that
the pump does not leak or have any
malfunctions.
9. The pump must be re-vented in these cases:
– The pump has been stopped for a period of
time.
– Air or gas has accumulated in the pump.
WARNING
Dry running
Death or serious personal injury
- Make sure that the pump is filled with
pumped liquid during operation.
Strictly observe the following check list.
