2 Introduction
Directive 2014/34/EU, commonly known as the ATEX directive, carries obligations to the person who
places equipment on the market, in the EU territory, for use in potentially explosive environments.
All of Watson-Marlow’s ATEX pumps have been rated as II 2G Ex h IIB T4 Gb X under the definitions of
2014/34/EU:
lEquipment group II
lEquipment category 2
lEnvironment G
lMechanical protection concepts EX h
lGas group IIB
lTemperature class T4
lEquipment protection level Gb
lSpecial operating restrictions X (see pumphead manual)
"Equipment category 2 comprises equipment designed to be capable of functioning in conformity with
the operational parameters established by the manufacturer and of ensuring a high level of protection.
Equipment in this category is intended for use in areas in which explosive atmospheres caused by gases,
vapours, mists or air/dust mixtures are likely to occur occasionally. The means of protection relating to
equipment in this category ensure the requisite level of protection, even in the event of frequently
occurring disturbances or equipment faults which normally have to be taken into account."
Watson-Marlow pumps must not be used in the underground parts of mines, and in surface
installations of such mines, likely to become endangered by firedamp and/or combustible
dust.
As stated in the Directive, where two or more items of ATEX equipment are combined, the complete
assembly shall carry the same rating as the lowest ranking individual piece of equipment.
All Watson-Marlow ATEX pumps covered by this manual are intended for use in gas based environments
only.
If you are unsure about the meaning of this ATEXrating see section 13 "ATEX marking" on page19 or
contact your Watson-Marlow representative for advice. Watson-Marlow representatives can advise which
rating and approvals products carry, but cannot evaluate nor recommend which product may be
suitable for use in an end users hazardous installation. Only the end user or their qualified representative
can confirm the ATEX rating of the equipment meets the requirements of their installation.

9 Installation
Preliminary checks
DANGER! - EXPLOSIONHAZARD
Failure to inspect the pumphead unit for damage or check the ATEX
labelling data may cause a fire or explosion.
Check the label on the pump to ensure that the pump type and the ATEX labelling conform to the
planning of the plant or machine.
Check that all components are present. Inspect components for damage in transit. If anything is missing
or damaged, contact your Watson-Marlow representative immediately.
Mechanical installation
Fundamental work with regard to lifting, transportation, installation,
starting-up, maintenance and repair should be performed by qualified
personnel only. The unit must be isolated from mains power while
work is being carried out. The motor must be secured against
accidental start-up.
Some pumps weigh more than 18kg (the exact weight depends on the
model and pumphead - see on the pump). Lifting should be performed
according to standard Health and Safety guidelines.
Explosion hazard. Failure to comply may cause severe or even fatal
injuries.
All work, e.g. transportation, storage, installation, connection,
commissioning, servicing and maintenance must be performed in a
non-explosive atmosphere.
Site the pump on a flat, horizontal, vibration-proof surface allowing a free flow of air around it. Ensure
there is 0.5m of straight tubing before the pumphead inlet and after the pumphead outlets.
If the pump is not supplied attached to a baseplate then the unit must be bolted down to a suitable
substrate via the bolting holes identified in the motor and gearbox manuals.
Refer to the manufacturers instructions for the motor and gearbox for further installation instructions.

All Watson-Marlow ATEX rated pumpheads include provision for the prevention and dissipation of
electrostatic charge. In order to dissipate electrostatic charge effectively there must be sufficient electrical
contact between the pumphead and the suitably earthed drive.
It is imperative that the 500, 600 and 700 series ATEX pumps are earthed. The pumphead
guard, track, gearbox and motor and baseplate (where applicable) already have earth
straps installed. The user must ensure that these earth straps are connected to a suitable
earth point on installation.
It is possible to check the effectiveness of any earth connection by measuring its electrical resistance. To
ensure reliable dissipation of static, the maximum resistance from the earth point
identified above to earth should not exceed 1 MOhm.
Peristaltic tubing is insulating and so its use should be limited to the length adjacent to the pumphead.
Earthed, conductive pipework should be used elsewhere in the system.
AC motor/Air motor
Please refer to the manufacturer’s instructions as supplied with the ATEX certified motor.
9.1 Do’s and do not’s
Do not build a pump into a tight location without adequate airflow around the pump.
Do keep delivery and suction tubes as short and direct as possible and follow the straightest route. Use
bends of large radius: at least four times the tubing diameter. Ensure that connecting pipework and
fittings are suitably rated to handle the predicted pipeline pressure. Avoid pipe reducers and lengths of
smaller bore tubing than the pumphead section, particularly in pipelines on the suction side. Any valves
in the pipeline (not usually needed) must not restrict the flow. Any valves in the flow line must be open
when the pump is running.
Do use suction and delivery pipes equal to or larger than the bore of the tube in the pumphead. When
pumping viscous fluids use pipe runs with a bore several times larger than the pump tube.
Do ensure that your system fluid supply and discharge pipework is suitable for the hazardous
environment in which the pump is operating and doesn't allow for the accumulation of electrostatic
charge.
Do site the pump at or just below the level of the fluid to be pumped if possible. This will ensure flooded
suction and maximum pumping efficiency.
Do keep the pumphead track and all moving parts clean and free from contamination and debris.
Do run at slow speed when pumping viscous fluids. Flooded suction will enhance pumping
performance in all cases, particularly for materials of a viscous nature.
Do limit peristaltic tubing to the length adjacent to the pumphead because peristaltic tubing is insulating.
Electrostatic testing has been used to determine which Watson- Marlow tubing is suitable for use in
hazardous environments. Refer to pumphead manual for more information. Earthed, conductive
pipework should be used elsewhere in the system.
When using Marprene or Bioprene continuous tubing, do re-tension the tube after the first 30
minutes of running.

16 PB0448:m-501-621-701atex-en-01
Tube selection: The chemical compatibility lists published in Watson-Marlow publications are guides. If
in doubt about the compatibility of a tube material and the duty fluid, request a Watson-Marlow tube
sample card for immersion trials.

10 Start-up
If the unit has been supplied integrated with a air filter, lubricator and regulator then please refer to the
manufacturers instructions as supplied, in conjunction with the recommendations in the air motor
operating manual.
Please refer to the pumphead instructions to ensure correct loading and operation of the pumphead.
Prior to start-up ensure that the tubing material used is listed in the "Special conditions of use for safe
operation - Tube materials suitable for use with this equipment" section of the pumphead manual.
The unit will self prime, minimise the time to prime the pump as dry running will reduce the life of the
tube.
10.1 Check list for installation in explosive environments
Complete the following check list prior to starting installation in an explosive environment. All actions
must be completed in accordance with Directive 2014/34/EU.
lCheck ATEX pump and motor labelling and configuration. Ensure that they conform to actual
installation (see section 13 "ATEX marking" on page19).
lCheck the ambient temperature of the site and the ability to maintain proper ambient temperature.
(see section 7 "Pump specification" on page12).
lCheck the site to make sure that the motor will be adequately ventilated and that there is no external
heat input (e.g. couplings). The cooling air may not exceed 104ºF/40ºC.
lCheck that the pump is not damaged.
lCheck the installation has been carried out correctly in accordance with pumphead, gearbox and
motor manufacturers instructions.
11 Troubleshooting
Should the pump fail to operate, make the following checks to determine whether or not servicing is
required.
lRefer to the motor manufacturer's manual to ensure correct connection of the electrical or air
supply.
lCheck that the pump is not stalled by incorrect fitting of tubing.
Any deviation from normal operating conditions (increased power
consumption, temperature, vibrations, noise) or warning signals by
monitoring equipment suggest malfunction. Inform the responsible
maintenance personnel at once to prevent the trouble from worsening.
If in doubt disconnect the pump immediately.

12 Maintenance
The pump should be cleaned regularly to avoid the accumulation of dust, this will prevent build up of
electrostatic charge due to the presence of dust. This product is not certified for use in ATEX dust
environments.
Visually inspect the earth straps monthly to ensure mechanical integrity. Electrical conductivity of the
earth system must be verified six monthly.
On the 701 series ATEX products, the shaft coupling should be examined every six months for signs of
wear to the spider. If the spider is worn then it should be replaced. Please refer to the shaft coupling
manufacturers instructions.
Monthly visual inspection must be undertaken to determine if the product has been damaged due to
(but not limited to) adverse operating conditions caused by worn components, loose bolts or
