Safety
instructions
inspection and assembly work
The user must ensure that all maintenance, inspection and
assembly tasks are carried out by authorised, qualified,
specialised personnel who have been sufficiently informed
through careful study of the instructions manual.
It is a fundamental principle that any work on the machine
must be carried out whilst it is shutdown. It is essential to
respect the pump shutdown procedure described in the
instructions manual.
When the pump is stopped it is liable to remain under
pressure.
The
pump
environmental temperature. Before dismantling it, is must be
depressurised by making drain openings (or air vents) leading
to a safe area.
All pumps or motor pumps which pump hazardous materials
must be decontaminated.
Connect an earth conductor to the metal casing of the pump
or baseplate if the fluid handled is electrostatically charged.
Never connect the earth of the electric welding equipment to
pump or baseplate.
As soon as the work is complete, all safety and protection
devices must be installed and put into operation.
Before starting up again, all that described in the First Start-Up
section must be fulfilled.
Due to the fact that the unit contains small parts such as
nuts, screws, etc., whose accidental contact may lead to
small cuts on the hands, operators are recommended to
use gloves when handling.
The following additional risk-prevention instructions
shall be fulfilled:
The pumped liquid may cause injuries, burns, poisoning, etc. It
is therefore necessary:
-
To check the temperature and amount of leaks occurring
at the mechanical seal or packing area. Conduct such
leaks to a safe area through a controlled drainage
system, specially indicated for the case of break of
mechanical seal.
-
To take appropriate measures to avoid direct contact with
the pumped liquid when it is necessary to prime or fill the
pump or unit.
-
Before dismantling the pump, if the liquid is toxic or
dangerous, it must be decontaminated. For this purpose
the unit must be cleaned inside by introducing a cleaning
liquid into the pump and emptying it subsequently
through the drainage connection. The cleaning liquid
must not create hazardous situations and must be
compatible with the pump components (CONSULT)
-
To take appropriate measures to avoid contact with the
pump if liquids are pumped at temperatures over 40ºC.
-
In the event of a liquid with high steam pressure being
used, beware of the danger of explosion due to pressure
confinement with the pump stopped. This confinement
must be avoided by opening inlet or discharge valves, or
by providing a properly conducted air-vent connection in
the pump discharge for liquid evacuation.

For rotating parts:
-
The pump should never work without its coupling guard
in place and firmly secured.
-
Do not wear loose or baggy clothing or wear long hair
loose near rotation areas to avoid clothes or hair getting
caught and causing serious accidents.
-
Do not force jammed rotating parts manually when the
pump is in operation.
When the pump is joined to considerably long piping,
waterhammer may occur when it is stopped. Should this arise,
appropriate anti-waterhammer elements must be put in place.
to
All the safety regulations indicated by the pump drive
manufacturer must be observed and complied with.
Inappropriate installation may lead to the unit breaking and
consequent risks to persons and/or the environment. It is
therefore necessary to:
-
Vent the pumps appropriately before operation, checking
that the pump is full of liquid.
-
Check that the pump discharge and suction valves are
fully open and that there is no dirt or foreign bodies in the
piping.
Regarding overload conditions:
-
Do
not
exceed
(temperature, suction pressure, discharge pressure,
rpm.) indicated in this instructions manual, offer and
technical catalogue.
-
Do not exceed the maximum loads permitted on the
suction and discharge connections.
-
The pumps must only be used in the conditions and with
the liquid indicated in the offer and/or order.
An unforeseen failure in the drive power may lead to danger
due to spontaneous start-up of the unit; it is up to the
customer to take the necessary steps to avoid this.
When the CONTROL SYSTEM is not supplied by KSB ITUR,
the customer is responsible for the entire machine complying
with the machine safety directive, including these controls
2.7
Modifications and arbitrary manufacture of
spare parts
The machine must not be modified or changed without prior
agreement from the manufacturer. Only original spare parts
and accessories approved by the manufacturer can guarantee
safety. The use of other parts invalidates any liability of KSB
ITUR for consequential damage.
2.8
Unauthorised operation modes
The safe service of the supplied pump can only be guaranteed
through correct use, in line with section
Manual. The operation limits established in the Datasheet
must not be exceeded under any circumstance.
If flammable fluid, it must be ensured at all times that the
pump is full of liquid, so that there is never an explosive zone
0 inside it. In addition, the parts subjected to pressure must be
of ductile material
