Maintenance • General Pump Care
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 18. For quarterly
and annual maintenance, refer to check list on the
following page. 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 Page 25 when selecting spares.
• Mechanical Shaft Seal
• 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 con-
sequences, 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. 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.
