LUBRICATION:

LIQUID END of pump requires no lubrication. Wear
rings and packing rings are lubricated by the liquid being
pumped. Do not run dry!
BEARING FRAME uses sealed bearings. No additional
lubrication is required.
ELECTRIC MOTOR: Refer to motor manufacturer's
operating manual for complete instruction.
GAS/DIESEL ENGINE: Refer to engine manufacturer's
operating manual for complete instruction.
PERFORMANCE CHECk:
Periodically check the output of the pump. If perform-
ance is noticeably reduced, refer to Troubleshooting
Chart.
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.
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.

General Information

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.
PACkING:
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 tighten gland nuts one complete turn
each until leakage is reduced to 40 to 60 drops per
minute.
REPACkING:
Refer to illustrations on Page 20.
PUMP PROTECTION-
COLD WEATHER/WET WEATHER
INSTALLATIONS:
SYSTEM DRAINS: Provide drain valves to empty sys-
tem, 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. When effectively sheltered, a small amount
of heat will keep temperature above freezing. Provide
adequate ventilation for unit when running. For severe
weather problems, where other shelter is not practical, a
totally enclosed fan-cooled enclosure can be considered
for electric motors.
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.
