sheet".

2.3 Pumped liquids

The pumps are suitable for thin, clean liquids, not

containing solid particles or fibres.

2.4 Explosion protection documentation

The combination of NB, NBG, TP, TPD pumps and all

monitoring equipment must be described in the

explosion protection document according to the

Directive 2014/34/EU. The responsibility rests with

the installer or owner.

SIGNAL WORD

Description of hazard

Consequence of ignoring the warning.

- Action to avoid the hazard.

A blue or grey circle with a white graphical

symbol indicates that an action must be

taken.

A red or grey circle with a diagonal bar,

possibly with a black graphical symbol,

indicates that an action must not be taken

or must be stopped.

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.
