Installation
8INOXPA S.A.U. 01.030.30.03EN · (C) 2022/11
Ensure air recirculation for cooling the pump motor. Make sure there are no other equipment or surfaces near the
engine that could radiate additional heat or affect the engine cooling. See engine instructions manual.
5.5. ADJUSTABLE FEET
Not applicable in this ATEX Annex.
5.6. PIPES
Before starting the pump, make sure that the suction and discharge valves of the pump are open.
Make sure to stop the pump before closing the suction and discharge valves.
5.6.1. Shut-off valves
Use CE marked valves in accordance with the regulations on hazardous areas or explosive atmospheres in force,
in accordance with the manufacturer's instructions and the national and local regulations.
5.7. PRESSURIZATION TANK
For models with double mechanical seal, it may be necessary to install a pressurization tank. Ensure that the tank
is always pressurized 1.5 - 2.0 bar higher than the working pressure of the pump when it is running, even when it
is started or stopped. See the instruction manual for the mechanical seal and pressurization canister.
Verify that the instrumentation in the pressurization tank is suitable for the work area.
5.8. ELECTRICAL INSTALLATION
Before connecting an electric motor to the network, check the local regulations on electrical safety, as well as the
standards EN 60204-1 and EN 60079-14 current at the moment. Also, the supplier's instruction manual. This
motor must be suitable for working in an explosive zone with adequate protection for the work environment in
which it must operate.
Respect the engine manufacturer's instructions at all times.
Install the motor overload protections, appropriate to the nominal power of the motor.
Install, if necessary, an independent fan, taking into account the atmosphere in which said fan must work
(potentially explosive atmosphere).
Electrical equipment, terminals, and control system components can still carry current when disconnected.
Contact with them can endanger the safety of the operators and the installation or cause irreparable damage to
the material, which is why the supplier's instructions for the safe opening of the motor must be respected at all
times.
Establish safe work permits for any manipulation of the equipment in the presence of potentially explosive
atmospheres, advising to carry out this type of work in unclassified atmospheres (in the location of the pump
where there is no explosive atmosphere during its manipulation).
The direction of rotation must be controlled with the motor decoupled from the pump, or with the pump fully primed
and, in the case of a double pressurized mechanical seal, the seal chamber filled with liquid.
When pumping flammable or explosive liquids, use a suitable connection. Connect the components of the unit
with the ground jumpers to reduce the danger from static electricity.

INOXPA S.A.U. 01.030.30.03EN · (C) 2022/11 9
6. Starting the pump
Before starting the pump, the responsible persons must be duly informed about the pump and the safety
instructions.
This annex together with the instruction manual must be, at all times, at the disposal of the personnel.
Explosive atmospheres can be generated during the start-up of the pump, so safe work permits must be
established and these works must only be carried out by qualified personnel, in accordance with the regulations
on risk areas or explosive atmospheres in force.
6.1. CHECKS BEFORE STARTING THE PUMP
Make sure before starting the pump that the suction and discharge valves of the pump are open.
If there is a risk of dry work, install a flow detection probe in the pump suction, or any other safety device that
prevents dry work of the same.
In the case of simple (uncooled) shut-off, the pump and the shut-off area must be flooded with the pumped liquid
before starting the pump.
If the liquids to be drained are flammable, take into account the possible formation of potentially explosive
atmospheres and, therefore, the adoption of safe work permits.
6.2. CHECKS WHEN STARTING THE PUMP
Not applicable in this ATEX Annex.

8. Maintenance
8.1. GENERAL CONSIDERATIONS
Maintenance work on any equipment intended for use in potentially explosive atmospheres must involve the
adoption of safe work permits, as specified in the regulations on risk areas or explosive atmospheres in force.
These works may only be carried out by qualified personnel. Wear suitable clothing. Make sure that the personnel
read both the instruction manual and this annex and, in particular, the chapters referring to the work to be carried
out.
Use technically suitable tools for maintenance and repair work. If the area is not declassified, all tools must be
non-sparking and safe work permits must be established.
In addition to the safety instructions indicated both in the instruction manual and in this annex, always follow the
instructions provided by the motor manufacturer for safe opening of the motor.
When ordering spare parts for a pump to work in a classified area, explicitly indicate in the order that it is an ATEX
pump and indicate the manufacturing number. If this is not done in this way, INOXPA is not responsible for the
pump working with parts that are not suitable for the classified area where it is installed.
8.2. CHECK THE MECHANICAL SEAL
Periodically check that there are no leaks in the shaft area.
For classified zone 1 or 21, daily review. For classified zone 2 or 22, weekly review.
For double mechanical seal: it is necessary to control the temperature, level and pressure of the barrier liquid,
and it is advisable to install an automatism that stops the pump when the temperature of the liquid exceeds the
temperature class of the classified area, or there is not the necessary level of liquid.
For simple mechanical seal + thermosensor: respect the instructions of the mechanical seal and the thermosensor
at all times, especially the connection of the temperature probe.
In the event that said mechanical seal works dry, the maximum temperature of its operating area may be
exceeded. For this reason, a simple mechanical seal cannot work dry under any circumstances.
-Check the proper functioning of the simple mechanical seal regularly.
-Check that the hydraulic part of the pump is always full of liquid during operation.
-Avoid pumping liquids that contain a large amount of gas.
The end user must ensure with a safety system that there is constant flow input to the pump and prevent it from
working dry (flow meter, flow detector or any other safety device).
Double mechanical seal option, balanced. It must be protected by controlling the cleaning fluid.
-Check the level of the feeding reservoir.
-Check the temperature of the cleaning liquid.
-Verify the pressure.
The cleaning liquid must always be under pressure when the pump is running.
-Check the condition of the cleaning liquid; change the cleaning liquid if it is contaminated with external liquid.
Cleaning liquid contamination is an indication of erratic or malfunctioning operation and should be inspected. For
example, the sealing system may leak on the media side or be open due to insufficient back pressure of the
cleaning liquid.
Simple mechanical seal + thermosensor option. Respect the manufacturer's instructions for the mechanical seal
and the probe at all times, especially the connection of the temperature probe.
