This symbol indicates safety
instructions where non-compliance would affect the
safe operation or protection of the pump unit.
This symbol indicates explosive atmosphere
zone marking according to ATEX. It is used in
safety instructions where non-compliance in the
hazardous area would cause the risk of an
explosion.
This sign is not a safety symbol but
indicates an important instruction in the assembly
process.
1.6.2 Personnel qualification and training
All personnel involved in the operation, installation,
inspection and maintenance of the unit must be
qualified to carry out the work involved. If the
personnel in question do not already possess the
necessary knowledge and skill, appropriate training
and instruction must be provided. If required the
operator
may commission the
manufacturer/supplier to provide applicable
training.
Always coordinate repair activity with operations
and health and safety personnel, and follow all
plant safety requirements and applicable safety and
health laws and regulations.
1.6.3 Safety action
This is a summary of conditions and actions to
prevent injury to personnel and damage to
equipment.
LEVELED FUNDATION PLATE
Fundation plate or suction barrel flange must be
leveled within 0.050mm ( 0.002 in.) as maximum
variation which is indispensable for operation free
of trouble.
Use a rectified long bar in order to support
precision level across the foundation plate (side-to-
side) and levelling all directions every 45 degrees.
Foundation plate must be verified before and after
pour the grouting.
PREVENT EXCESSIVE
EXTERNAL PIPE LOAD
a) Do not use pump as a support for piping.
Piping must be independently supported
and must not be drawn into position with
flange bolting. Pipe strains on the pump can
be a definite source of trouble, resulting in
possible misalignment, excessive wear,
vibration and even broken shafts.
b) If expansion joint is used, employ tie rods
of adequate strength (i.e. size for 1-1/2
times shut off pressure).
c) Ensure pump and piping is flushed before
use .
ENSURE CORRECT
LUBRICATION
When external water source or oil is needed for
lubrication-see General Arrangement Drawing.
(See drawings attached)
See section 5.3, Direction of rotation
before connecting the motor to the electrical supply.
START THE PUMP WITH OUTLET
VALVE PART OPENED 30%.
(Unless otherwise instructed at a specific point in
the
user instructions, see section 5,
Commissioning, start up, operation and shutdown.)
This is recommended to minimize the risk of
overloading and damaging pump motor at full or
zero flow. The pump outlet control valve may need
to be adjusted to comply with the duty following the
run-up process.
DO NOT RUN THE PUMP AT
ABNORMALLY HIGH OR LOW FLOW RATES
Operating at a flow rate higher or lower than normal
may overload the motor and cause cavitation,
instability and vibration.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate sitting of the pump, limiting personnel
access and by operator training. If the liquid is
flammable
and/or explosive, strict safety
procedures must be applied.
HANDLING COMPONENTS
Many precision parts have sharp corners and the
wearing
of appropriate safety gloves and
equipment is required when handling these
components. To lift heavy pieces above 25 kg (55
lb) use a crane appropriate for the mass and in
accordance with current local regulations.
