Steady Bearings:
1. Carbon and Carbon Filled Teflon - These
bearings are chemically inert in most liquids
and can be used in liquids up to the
temperature limits of the pump. They should
not be used in liquids containing abrasive
solids. Clear flush from the support plate is
required.
2. Fluted Rubber or Viton - These bearings
consist of fluted rubber or Viton contained
within a metal shell. Clear water from an
outside source, 1 to 2 GPM, is required to each
bearing housing. They are ideally suited for
liquids containing abrasive solids but are limited
to 160°F temperature liquid. Corrosion resistant
shafting is required.
3. Metallic Bearing - Bronze steady bearings are
available and must be grease lubricated. Lack
of lubrication can lead to galling and eventual
seizing. It becomes extremely difficult to keep
enough grease in the housing when handling
hot liquids, caustic solutions or solvents.
Unless an adequate maintenance program
exists, it is recommended that a self-lubricating
bearing such as carbon be used in place of the
metallic bearing.
4. Sealed Bearings - Recommended for abrasive
liquids where no outside flush is available. The
carbon bearing is sealed within the housing by
two lip seals and filled by grease via pressure
lubricator located above the support plate. The
pressure cup must be kept full of grease. The
control screw on the pressure cup should be
wide open to start and then controlled by
usage.
NAMEPLATE INFORMATION
Pump Nameplate – Every pump has a Goulds nameplate that provides information about the pump. The tag is
located on the motor support. When ordering spare parts you will need to identify pump model, size, serial
number, and the item number of required parts. Information can be found in this manual. Part numbers can also
be found on the Repair Data Sheet supplied with the original pump data package.
