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.

5.2 Non-flammable liquids
EPL Gb/Db (category 2G/D)
If the operator cannot ensure that the pump is filled
with pumped liquid during operation, appropriate
monitoring, for instance dry-running protection, is
required to stop the pump in case of malfunction.
EPL Gc/Dc (category 3G/D)
No additional monitoring is required.
5.3 Flammable liquids
EPL Gb/Db, Gc/Dc
If the operator cannot ensure that the pump is filled
with pumped liquid during operation, appropriate
monitoring, for instance dry-running protection, is
required to stop the pump in case of malfunction.
Ventilation around the pump is also required. The
leakage rate of a normally working shaft seal is less
than 36 ml for each 24 hours of operation. A
minimum air exchange of 1.5 times per hour is
required.
5.4 Checking the direction of rotation
6. Servicing the product
Service on the pump end can be made on site. The
pump end does not need to be shipped to an
approved ATEX workshop.
1. Check on a daily basis that the shaft seal
functions correctly.
2. Any standby pump installed must be switched on
once a week to keep it operational.
3. It is the responsibility of the customer to do the
following:
– Decide whether to use the non-sparking tools
or to shut down the system for service.
– Lay down a cleaning scheme for pump
surfaces in installations with combustible dust.
4. When cleaning a pump in a combustible dust
environment, remember to take the shaft guard
off and clean the shaft cavity.
Fig. 10 Take the shaft guard off
5. Inspect O-rings for cracks, elasticity, and
permanent change of shape when doing periodic
maintenance or servicing the pump. Renew O-
rings if necessary.
6. Torques for all fasteners can be found in the
service instructions for NB, NBG and TP, TPD
products.
CAUTION
Flammable material
Minor or moderate personal injury
- The responsibility for checking the
functions of the dry-running protection,
such as flow rate, sealing pressure and
temperature of the barrier or flushing
liquid rests with the installer or owner.
Increased leakage can be the indication of
shaft seal failure. For some types of liquids
the leakage will not be visible due to
evaporation.
Never check the direction of rotation by
starting the pump, not even for a short
period, unless the pump has been filled
with liquid. This is to prevent temperature
rises resulting from contact between
rotating and stationary components, and to
protect the shaft seal against dry running.
Strictly observe the following check list.
It may be overruled by stricter local
maintenance schedules.

7. Technical data
7.1 Operating conditions
7.1.1 Liquid temperature
The maximum liquid temperature depends on the
temperature class specified by customer and the
shaft seal.
The illustration below shows the maximum surface
temperature of the pump as a result of maximum
liquid temperature and temperature rise in the shaft
seal.
Fig. 11 Calculation of maximum surface
temperature
The maximum surface temperature of the pump must
be at least 5 °C lower than the maximum surface
temperature of the temperature class specified by
the customer.
The maximum liquid temperature and the
temperature class specified by the customer are
stated on the "key application data sheet" supplied
with the pump. See the example at the end of this
document.
A copy is filed by Grundfos and can be traced by
means of the product number and serial number on
the pump nameplate.
Fig. 12 Model, product number, production site,
year, week, and serial number
7.1.2 Ambient temperature
The ambient temperature range in operation is -20 to
+60 °C for the pump-end.
8. Disposing of the product
This product or parts of it must be disposed of in an
environmentally sound way:
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
The crossed-out wheelie bin symbol on
a product means that it must be
disposed of separately from household
waste. When a product marked with this
symbol reaches its end of life, take it to a
collection point designated by the local
waste disposal authorities. The separate collection
and recycling of such products will help protect the
environment and human health.
