ROUTINE MAINTENANCE
A well maintained pumping system will extend the life of
the unit and will require fewer repairs. This means less
down time which can be very critical when a constant
delivery of water is required.
A routine maintenance and inspection schedule should
be set up on a weekly, quarterly, and annual basis with
records kept of these actions. For weekly checks see
observational maintenance on Page 15. For quarterly
and annual maintenance, refer to check list on Page 22.
Copy page as necessary for continual usage.
RECOMMENDED SPARE PARTS
It is recommended that the following spare parts be kept
on-site as a minimum back-up to service your pump and
reduce down-time. Check your model/style against parts
breakdown drawing on Pages 18 and 19 when selecting
spares.
• Mechanical Shaft Seal
• Packing Set and Packing Hooks
• Shaft Sleeve(s)
• All Gaskets and O-Rings Required for One Pump
• Oil Seal(s)
• Bearings
If having a pump non-operational has severe con-
sequences, a back-up pump should be considered.
Otherwise, a back-up impeller, volute case, bearings
and shaft, would be prudent.
PUMP 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. 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.
WINTERIZING
If pump is to be out of service for an extended period of
time, such as the winter months, the following storage
procedures should be followed.
• Remove exterior dirt and grime or any substance that
may trap moisture. Exposed metal is subject to
oxidation, prime and repaint if necessary. If this is not
possible, coat with grease or heavy oil.
• Flush suction and discharge lines. Check for leaks at
this time and replace any worn gaskets.
• Remove lowest plug in pump and drain pump casing
and suction and discharge lines.
• Lubricate bearings.
• If possible, keep unit clean and dry during storage
period to guard against corrosion.
• Seal all open ports to keep out foreign objects such
as insects, rodents, dust and dirt.
• Rotate driver shaft periodically to prevent freeze-up of
internal components.
• Shelter unit from elements if possible.
• Work oil into impeller wear ring by dripping oil into the
gap while rotating by hand.
SPRING START-UP
• Inject sufficient grease into the bearings to displace
old grease.
• Visual inspection.
• Rotate by hand, if any binding occurs, disassemble
and inspect.
