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.
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
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, actio n must be
taken to avoid accidental contact (suc h as shieldi ng). If
complete protection is not possible, the mach ine access
must be limited to maintenance staff only with cl ear
visual warnings and indicators to those e ntering 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
