following chapters. They are indicated with a danger symbol as follows.
2.1 SYMBOLS USED IN THESE
INSTRUCTIONS
General danger for user.
Danger due to electrical voltage.
Non-observance of the safety instructions can result in damage to
product/installation.
Refers to additional requirements, that the pump should comply
to when operated in hazardous areas.
This is not a security symbol. It is a note that gives additional
useful information about the way to use the pump.
2.2 PERSONNEL QUALIFICATION
Personnel involved in operation, installation, inspection or
maintenance of the pump and accessories must be adequately
qualified.

by anyone who will use this pump.
2.3 DANGER IN EVENT OF NON-
OBSERVANCE OF THE SAFETY
INSTRUCTIONS
Non-observance of the safety instructions can result in risk of
injury to persons and damage to product/installation. Non-
observance of the safety instructions can result in the loss of any claims
to damages.
In detail, non-observance can, for example, result in the following risks:
-
Failure of important product/installation functions,
- Failure of required maintenance and repair procedures,
- Danger to persons from electrical, mechanical and chemical,
thermal risks, …
-
Property damages,
- Loss of ex-proof protection,
- Risk of environmental pollution.
2.4 SAFETY INSTRUCTIONS
2.4.1 SAFETY INSTRUCTIONS FOR THE OPERATOR
OPERATION ON THE PUMP SET :
Make sure that electric power is switched off before maintenance
operations starts. Electrical protection should not be removed
while pump is running.
Empty pump casing and isolate piping before starting dismantling
of pump. If dangerous liquid was pumped the pump should be
decontaminated and cleaned prior to dismantling.
HANDLING OF COMPONENTS :
Some machined parts may have sharp edges. Wear safety gloves
and use necessary protections to handle them.
A lifting device must be used to lift parts exceeding 25Kg. Use
lifting device in accordance with local regulations.
HOT OR COLD PUMP PARTS:
Avoid accidental contact with very hot or very cold components.
Actions must be taken if their surface temperature is higher than
68 °C or below -5°C : (pump or accessories). If a complete protection is
not possible, the access to the machine must be limited to maintenance
staff only. A clear visual warning panel must be attached in the
immediate area to indicate the danger.
HAZARDOUS LIQUIDS:
When the pump is handling some dangerous liquids, a special care
must be taken to avoid exposure to the liquid. Make sure the
pump is set in an appropriate location and access to the pump must be
limited. Operators should be trained to potential risks.
If the liquid is flammable and/or explosive, strict safety procedures
must be applied.
2.4.2 SAFETY INSTRUCTIONS FOR THE EQUIPMENT
Quick temperature changes of the liquid contained in the pump
should be avoided. A thermal shock may drive to damages or
destruction of components, creating leakages.
Ensure that pump flanges do not support excessive external forces
when fastening piping flanges or after increasing of liquid
temperature. Do not use pump as a support for piping. If expansion
joints are used they should be equipped with axial movement limiting
device.
Before checking direction of rotation make sure that no parts
could be ejected from shafts (pins, keys, coupling element …).
Several pump types will be damaged if started in the wrong direction of
rotation (screwed impeller design). The flexible coupling of a pump set
must be disconnected before first start up to check direction of rotation.
Unless otherwise indicated and if it is possible, pump should be started
with discharge valve partially opened to avoid overloading of the motor.
The pump outlet control valve may need to be adjusted to reach the
requested duty point.
Never run the pump with a closed suction valve. The valves
located on suction side of pump must always remain opened while
pump is running.
