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 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
•Mechanical Shaft Seal
•Packing Set and Packing Hooks
•Shaft Sleeve(s)
•All Gaskets and
•Oil Seal(s)
•Bearings
If having a pump
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
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
•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.
