Figure 22: Oil lubrication components
1. Oiler
2. Breather vent
3. Sight glass
4. Pipe nipple connection
Before assembling oiler components onto the pump, ensure all required components are
on hand. Oiler kits should include (2) glass bulb oilers, (2) pipe nipple connections, (2)
sight glasses, (2) breather vents, and (4) pipe plugs. Flush the bearing housing of dirt and
debris using a light oil to prevent bearing damage during pump operation.
Note: Only one bulb oiler and sight glass are required per bearing housing. Choose an
appropriate side of the pump for installation of oiler components. Ensure all oiler
components are easily accessible for future maintenance.
1. Thread the pipe nipple connection into the smaller diameter port along the side of the
bearing housing.
2. Thread the sight glass into the larger diameter port along the side of the bearing
housing.
3. Plug unused pipe connection and sight glass ports located on the other side of the
bearing housing. Ensure any unused monitoring equipment ports are plugged.
1. Note: It is important to properly seal the bearing housing to prevent foreign debris
and moisture from accumulating within the bearing cavity. Follow routine
maintenance guidelines outlined in Maintenance schedule on page 36 and Bearing
and coupling lubrication on page 38 to ensure long bearing life.
4. Fasten the pipe plug located underneath the bearing housing into place.
5. Thread the breather vent into the top of the bearing housing.
