6.1 Lubrication
NOTICE:
Operation of the unit without proper lubrication will cause bearing failure, and pump seizure.
NOTICE:
Pumps are shipped without oil. Oil lubricated bearings must be lubricated at the job site.
Oil lubricated bearings must be lubricated at the job site. Remove fill plug and add oil until level is at the
center of the sight glass. Replace fill plug.
Change the oil after 2000 hours for new bearings, thereafter every 2000 operating hours or 3 months
(whichever comes first). Change more often if oil becomes contaminated with dirt or water.
A high quality turbine oil with rust and oxidation inhibitors should be used. For the majority of operational
conditions, bearing temperatures will run between 60°C (140°F) and 82°C (180°F). In this range, an oil of
ISO viscosity grade 68 at 40°C (105°F) is recommended. If bearing temperatures exceed 82°C (180°F),
use of ISO viscosity grade 100 is recommended.
