Goulds Pumps 3393 - IOM - Manual (Page 51)

Maintenance
• Check that the foundation and the hold-down bolts are tight.
• Check the shaft alignment, and realign as required.
Annual inspections
Perform these inspections one time each year:
• Check the pump capacity.
• Check the pump pressure.
• Check the pump power.
If the pump performance does not satisfy your process requirements, and the process
requirements have not changed, then perform these steps:
1. Disassemble the pump.
2. Inspect it.
3. Replace worn parts.
Bearing maintenance
Bearing replacement
• The end suction arrangement uses a silicon carbide sleeve bearing which is retained in a
holder integral with the end suction casing.
• The radial suction arrangement uses a bearing housing identical to the bearing housing on
the discharge side but with a single row ball bearing for radial loads.
• The discharge side bearing housing has back to back angular contact thrust bearings and
the 5" (125mm) discharge size and larger has a cooling fan mounted on hte pump shaft..
• Clean and check condition of all parts that have been removed. When in doubt,
components should be replaced. Wearing parts (ball bearings) and seals must always be
replaced.
• If parts or half-open pumps are to be stored for any length of time, they must be protected
from dirt and corrosion.
Maintenance of Bearings
OIL LUBRICATED BEARINGS
WARNING:
Make sure that the unit cannot roll or fall over and injure people or damage property.
After the pump has been installed, flush the housing to remove dirt, grit, and other impurities
that may have entered the bearing housing during shipment or installation; then refill the
housing with proper lubricant.
Note: Do not fill the oil reservoir of the bearing frame through the vent or through the
oiler housing without using the oiler bottle. The oil level will be maintained by the Trico
oiler.
