THERMAL SHOCK
Rapid changes in the temperature of the liquid within
the pump can cause thermal shock, which can result
in damage or breakage of components and should be
avoided.
HOT (and cold) PARTS
If hot or freezing components or auxiliary heating
equipment can present a danger to operators and
persons entering the immediate area, action must be
taken to avoid accidental contact (such as shielding). If
complete protection is not possible, the machine access
must be limited to maintenance staff only with clear
visual warnings and indicators to those entering the
immediate area. Note: bearing housings must not be
insulated and drive motors and bearings may be hot.
If the temperature is greater than 80 °C (176°F) or
below -5 °C (23 °F) in a restricted zone, or
exceeds local regulations, action as above shall
be taken.
HAZARDOUS LIQUIDS
When the pump is handling hazardous liquids care
must be taken to avoid exposure to the liquid by
appropriate pump placement, limiting personnel
access and by operator training. If the liquid is
flammable and/or explosive, strict safety procedures
must be applied.
PREVENT EXCESSIVE EXTERNAL
PIPE LOAD
Do not use pump as a support for piping. Do not
mount expansion joints, unless allowed by Flowserve
in writing, so that their force, due to internal pressure,
acts on the pump flange.
NEVER EXCEED THE MAXIMUM
DESIGN PRESSURE (MDP) AT THE
TEMPERATURE SHOWN ON THE PUMP
NAMEPLATE
See section 3 for pressure versus temperature
ratings based on the material of construction.
1.6.4 Products used in potentially explosive
atmospheres
Measures are required to:
Avoid excess temperature
Prevent build up of explosive mixtures
Prevent the generation of sparks
Prevent
leakages
Maintain the pump to avoid hazard
Refer to the instruction manual provided
with the pump for more information.
1.6.4.1 Maintenance of the centrifugal pump to
avoid a hazard
CORRECT MAINTENANCE IS REQUIRED TO
AVOID POTENTIAL HAZARDS WHICH GIVE A
RISK OF EXPLOSION
The responsibility for compliance with maintenance
instructions is with the plant operator.
To avoid potential explosion hazards during maintenance,
the tools, cleaning and painting materials used must not
give rise to sparking or adversely affect the ambient
conditions. Where there is a risk from such tools or
materials, maintenance must be conducted in a safe area.
It is recommended that a maintenance plan and schedule
is adopted. (See section 6, Maintenance.)
1.7 Specific machine performance
For performance parameters see section 1.5, Duty
conditions. Where performance data has been
supplied separately to the purchaser these should be
obtained and retained with these User Instructions if
required
.
2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be
checked against the delivery/shipping documents for
its completeness and that there has been no damage
in transportation. Any shortage and/or damage must
be reported immediately to Flowserve Pump Division
and must be received within ten days of receipt of the
equipment. Later claims cannot be accepted.
Check any crate, boxes or wrappings for any
accessories or spare parts that may be packed
separately with the equipment or attached to side
walls of the box or equipment.
2.2 Handling
Boxes, crates, pallets or cartons may be unloaded
using fork lift vehicles or slings dependent on their
size and construction.
