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 main-
tenance on Page 16. For quarterly and annual maintenance,
refer to check list on the following page. Copy page as
necessary for continual usage.
For engine maintenance refer to engine manufacturer’s
owners/operators manual.
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
drawings on Pages 24 and 25 when selecting spares.
• Mechanical Shaft Seal (or)
• Packing Set and Packing Hooks
• Shaft Sleeve(s)
• All Gaskets and O-Rings Required for One Pump
• Impeller Wear Ring
• Retaining Rings
If having a pump non-operational has severe consequences, a
back-up pump should be considered. Otherwise, a back-up
impeller, volute case, bearings and shaft, would be prudent.
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. Coat machined surfaces 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 the wear ring by dripping oil into the gap while
rotating impeller by hand.
• Winterize the engine according to the engine manufacturer’s
instructions.
SPRING START-UP
• Inject sufficient amount of grease into bearing to displace old
grease.
• Perform a visual inspection of all components.
• Rotate by hand to be sure impeller and shaft turn freely. If
binding occurs, disassemble and inspect.
• Follow engine manufacturer’s recommendations for starting
the engine.
