For this reason,
operators of pumps and
other rotating equipment
often have difficulty
isolating the root cause
behind poorly performing
equipment.
Widely acknowledged for
our class leading pump
technology, Sulzer Pumps
is your ideal partner to
find the cause of a
poorly performing pump
system.
A typical project
consists of a study of
the complete
installation shaft line;
motor, turbine,
hydraulic-coupling,
gearbox, pump etc. The
existing instrumentation
schematics are also
reviewed to assess their
suitability for the
inspection process and
ongoing monitoring of
the installation.
Naturally, we are able
to provide full
instrumentation for the
inspection if required.
Measurement
During a typical site
inspection, we;
• Confirm pump duty
during normal operation
and under process upset
conditions
(flow, head, speed,
balance line flows etc.)
• Record vibration
parameters (both
absolute and relative
figures)
• Collect data during
the start up and run
down phases
• Temperature
measurement (bearings,
cooling systems, seal
flushes etc.)
• Check mechanical seals
for leaks
• Review operation of
minimum flow valve or
other control device
• Check for other
external leaks or
abnormal noises
Analysis and
recommendations
Measurements are
analyzed by our
engineers, who prepare a
detailed report covering
the following areas;
• Comparison of pump
current hydraulic and
mechanical performance
vs original test of
expected performance
• Estimate of balance
system wear (where
applicable)
• Recommendations for
any changes in general
operation (e.g.
temperature limits)
• Changes to existing
maintenance regimes
• Recommendations for
any system or process
changes
• Recommendations for
spare parts holding
• Proposal for pump
modifications if
applicable
Your key benefits are
• Knowledge of current
pump condition without
the need for a shutdown
• Potential to extend
pump operating time
between scheduled
maintenance periods
• Recommendations for
system and process
optimization
• Optimized spare parts
stocking
• Potential to upgrade
the pump with latest
technology and materials
• Direct and indirect
cost savings
