1 GENERAL INFORMATION
1.1 ABOUT THIS DOCUMENT
The original language of the operating instructions is French. All
other languages of these instructions are translations of the
original operating instructions.
This installation and operating manual is an integral part of the
equipment. It should be kept available near the equipment. It is
necessary to respect all instructions given in this installation and
operating manual to ensure a reliable and economic use of the
pump.
The installation and operating instructions corresponds to the
relevant variant of construction of the product and to applicable
safety standards valid at the time of going to print.
2 SAFETY
This operating instructions contain basic information that must be
respected during installation and operation. These instructions
must be read by the service technician and the responsible
operator before installation and commissioning starts.
It is not only the general safety instructions listed in this chapter
that must be respected but also the special safety instructions
mentioned in 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.
Qualification, knowledge evaluation and personnel supervision
must be strictly handled by the pump owner. If necessary,
SALMSON or one of its representative can perform adequate
training. Plant management must ensure that contents of the
operation instructions are fully understood 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.
Running continuously the pump at zero flow or below the
recommended minimum flow will cause damage to the
pump.
Never run the pump out of its operating limits. Operating
the pump at higher flow rates may overload the motor and
cause cavitations.
