Performance Check
Periodically check the output of the pump. If
performance is noticeably reduced, refer to
Troubleshooting.
Observational Maintenance
When the pump and system operation have been
stabilized, verify that pump unit is operating properly.
Observe the following:
Vibration: All rotating machines can be expected
toproducesomevibration.However,excessive
vibration can reduce the life of the unit. If the
vibration seems excessive, discontinue operation,
determine cause of the excessive vibration,
andcorrect.
Noise: When the unit is operating under load, listen
closely for unusual sounds that might indicate
that the unit is in distress. Determine the cause
andcorrect.
Operating Temperature: During operation, heat is
dissipated from the pump and the driver. After a short
period of time, the surface of the pump bracket will
bequitewarm(ashighas150°F),whichisnormal.
If the surface temperature of the pump bracket or
driver is excessive, discontinue operation, determine
cause of the excessive temperature rise, and correct.
 Bearingswillrunhotterforabriefrun-inperiodafter
packing,whichisnormal.However,wornbearings
will cause excessive temperatures and need to be
replaced. The pump unit is cooled by the water
flowing through it, and will normally be at the
temperature of the water being pumped.
Mechanical Seal: Adjustment or maintenance is
normally not required. The seal is enclosed within
the pump and is self adjusting. Seal is cooled and
lubricatedbytheliquidbeingpumped.Referto
Mechanical Shaft Seal section for removal and
replacement information. Do not run pump dry!
Pu mp Protection-Cold Weather/ Wet
Weather Installations
System Drains: Provide drain valves to empty system,
including pump case, to prevent freezing damage.
Shelter: If possible, provide shelter for unit to protect
from weather. Allow adequate space around pump
unit for service, as shown below.

Condensation: When the temperature of metal parts is
below dew point and the surrounding air is moist,
water will condense on the metal surfaces and can
cause corrosion damage. In severe situations, a
space heater can be considered to warm the unit.
