LIQUID END of pump requires no lubrication. Wear
rings and packing rings are lubricated by the liquid
being pumped. Do not run dry!
:
Periodically check the output of the pump. If perform-
ance is noticeably reduced, refer to Troubleshooting
Chart.
When the pump and system operation have been
stabilized, verify that pump unit is operating properly.
Observethefollowing:
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.
STUFFING BOX: After a short period of operation,
verify that the stuffing box area and gland are not
hot. If heating is detected, loosen the gland nuts
evenly until water is just running out of stuffing box
in a DROPLET form (approximately 40-60 drops per
minute). Water must not be streaming or spraying
out. Verify cool operation periodically. Adjust gland
nuts EVENLY as necessary for lubrication and cooling
of the packing. If packing has been tightened to the
limit of the packing gland travel, additional packing is
necessary.

running. If the pump is stopped and you think that the
packing gland needs adjusting, start the pump before
adjusting the nuts.
Starting new pump.
Before starting pump for the first time, loosen gland
nuts and retighten finger tight. Proceed with pump
start-up procedure. Allow packing to leak liberally for a
few moments. Then, with pump running, tighten gland
nuts one complete turn at a time each until leakage is
reduced to 40 to 60 drops per minute.

SYSTEM DRAINS: Provide drain valves to empty
system, including pump case, to prevent freezing
damage.
SHELTER: If possible, provide shelter for unit to
protect it from weather. Allow adequate space around
pump unit for service. When effectively sheltered, a
small amount of heat will keep temperature above
freezing. Provide adequate ventilation for unit when
running. Protect truck-mounted pumps from flying
debris.
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 installed to warm the unit.
