SPECIFIC CONDITIONS OF USE
The user of the pump and dampener shall provide relevant
information regarding the intended use (e.g. process liquid) to
the manufacturer for selection of suitable materials.
The external non-metallic parts of the products should be
protected from ultraviolet light at all times, including during
installation.
The actual use shall be within the specified limits and within
the ratings as shown on the nameplate of the pumps and
dampeners.
Depending on the applied pump materials and the intended
use; e.g. a non-conductive process liquid and a high liquid
flow, electrostatic charging of these materials may be
possible. The user shall conduct an assessment regarding
the risk of electrostatic charging and, if applicable, shall take
appropriate measures to reduce this risk to an acceptable
level. For the diaphragm materials the suitability as shown
above can be used for the assessment.
In case of application of diaphragm type TU or G the
assessment shall show its suitability.
In case of application of diaphragm type T or S the
assessment may show a wider suitability
3. SAFETY PRECAUTIONS
The safety precautions described here are important for
the safe and correct use of the product, to prevent harm to
yourself and to others, and damage to property.
Always confirm all applicable local laws, regulations and
codes in order to be able to take all necessary precautions
and to ensure correct usage of the product.
Before using the product, make sure you completely
understand all cautions and notes.
• Each product's wetted parts (parts that come into contact
with fluid) will be different depending on the product
model. Check a chemical resistance chart to make sure
your product's materials are suited to the fluid that is to be
pumped. Never use a chemical that is not suitable for the
material of the product or any of its parts. This may cause
permanent damage to the product, environmental damage,
possible injury or death.
• If the product is to transfer hazardous fluids (flammable,
acidic, chemically reactive, environmentally dangerous,
hot etc.), prepare safeguards such as placing the product
in a pit or protective box and use appropriate sensors to
warn against failure or to stop the product. Also make sure
that appropriate warnings are displayed on the product
and surrounding areas, and that all other safeguards are
carried out.

of Use
• Over time the torque tolerances on all parts comprising the
product may loosen. Periodically retighten all bolts to their
specified tolerances (please refer to the maintenance manuals).
• When you operate the pump, you may hear a loud operating
noise depending on the circumstances (such as fluids to
be transferred, supplied air pressure and fluid discharge
pressure). When necessary, for example if any law or
regulation is applicable for the use of the pump, take
appropriate measures for soundproofing it.
• If a diaphragm of the product is damaged, the supplied air
is mixed into the fluid or the fluid flows into the air switching
section of the product. Do not use the product, if the
supplied air or dust mixed in the supplied air affects the
damaged diaphragm, or if the chemical resistance of any part
consisting the main unit is not appropriate for any chemical.
• If a diaphragm were to fail, the fluid being pumped will be
blown out of the exhaust along with compressed air. Make
sure that all precautions are carried out to restrict the
possible environmental damage or injuries that may result.
Also make sure the chemical resistance and corrosion
resistance is compatible with any material that it may come
into contact with.
• If the product remains unused for a long period of time, or
you have misgivings about running the pump, consult the
dealer where you purchased the product.
• Make sure any fluid pipes or containers as well as the
exhausted air from the pump, does not affect or will not
affect any persons, animals, facilities or equipment.
• Follow all laws and instructions regulating the containment,
storage and use of any particular liquid.
• While the pump is operating, do not place your hand or any
other object near the material inlet.
• In some cases an additional risk may arise due to vapours
(for example gasoline, alcohols, solvents) or gases
resulting from escaping process fluids caused by leaking,
component failure or improper maintenance.
• Check chemical compatibility of all wetted components
(incl. seals) with all process and cleaning fluids to minimize
the risk of chemical reactions. Compatibility may change
with concentration and/or temperature.
• Incorrect material compatibility may cause corrosion of
materials, which may lead to leakages and very dangerous
situations for the environment, and can lead to fire,
explosions or even death.
• Process lines can be hot. When a diaphragm is damaged,
process fluids may extrude from the exhaust. A pipe or
hose may be connected to the exhaust to lead the exhaust
air away from the pump.
• Never block a leakage with any body part. Injected
materials can cause severe injury or death.
PERSONAL PROTECTIVE EQUIPMENT
• Always wear appropriate safety glasses and other safety
equipment during installation, operation, inspection and
maintenance. Use safety protection to avoid contact with
process fluids, cleaning fluids and other fluids. Gloves,
coveralls, face masks and other equipment may be required
to protect personnel.
• Always review the Safety Data Sheet (SDS) of the fluid and
follow all handling instructions.
POSSIBILITY OF HAZARDS
FIRE AND EXPLOSION HAZARDS
Always confirm all applicable local laws, regulations and
codes in order to be able to take all necessary precautions
and to ensure correct usage of the product.
(When pumping flammable fluids, always check the
applicable local environmental and workplace safety laws
in order to be able to take all necessary precautions and to
ensure correct usage of the product.)
• Improper grounding, poor ventilation, or unshielded fire or
spark can create a danger of fire or explosion.
• All peripheral equipment and piping connected to this
product should be properly grounded.
