START-UP PRECAUTIONS
NOTE: A build up of gases within the pump, sealing
system and or process piping system may result in an
explosive environment within the pump or process
piping system. Ensure process piping system, pump and
sealing system are properly vented prior to operation.
1 Running a new or rebuilt pump at slow speeds may
not provide enough flow to adequately flush and cool the
wear ring and throat bushing close running surfaces.
2
Pumped fluid temperatures in excess of 200°F
(93°C) will require warm-up of pump prior to operation.
Circulate a small amount of pumped fluid (typically through
the casing drain connections on the TSMP) until the casing
temperature at all points monitored is within 50°F to 75°F
of pumped fluid temperature. As a guideline, warm up the
pump at a rate of 50°F per hour. Average warming stream
rates are based on observations at various operating sites
and are indicated in
Table 2 for reference only.
1-Make sure suction valves and any recirculation valves are open.
4. Slowly open discharge valve until the desired flow cooling lines are open. is obtained.
2-Fully close or partially open discharge valve as dictated by system conditions.
3-Start driver.
1-All equipment and personal safety related devices and controls
must be installed and operating properly.
2-To prevent premature pump failure at initial start-up due to dirt
or debris in the pipe system, operate the pump continuously at
full speed and flow for 2 to 3 hours with suction strainers
installed.
3-Variable speed drivers should be brought to rated speed as
quickly as possible.
4-Variable speed drivers should not be adjusted or checked for
speed governor or overspeed trip settings while coupled to the
pump at initial start-up. If settings have not been verified,
uncouple the unit and refer to driver manufacturer’s instructions

Operation
�
CAUTION
Ensure that pump and systems are free of foreign
objects before operating and that objects cannot enter
the pump during operation. Foreign objects in the
pumped fluid or piping system can cause blockage of
flow which can result in excess heat generation, sparks
and premature failure.

CAUTION
Observe pump for vibration levels, bearing temperature
and excessive noise. If normal levels are exceeded,
shut down and resolve.
CAUTION
Immediately observe pressure gauges. If discharge
pressure is not quickly attained, stop driver, reprime
and attempt to restart.
