4.1.3 Lubricating bearings
NOTICE:
Operation of the unit without proper lubrication will cause bearing failure, and pump seizure.
Oil Lubrication
: Pumps are shipped without oil. Fill the bearing frame with oil, through the filler connec-
tion (located on top of bearing frame), until the level reaches the mark in the middle of the oil level sight-
glass. A high quality turbine type oil, with rust and oxidation inhibitors should be used.
NOTICE:
Pumps are shipped without oil. Oil lubricated bearings must be lubricated at the job site.
Refer to the Maintenance Section of this manual for further details on lubrication.
4.1.4 Shaft sealing
CAUTION:
Never operate the pump without liquid supplied to mechanical seal. Running a mechanical seal
dry, even for a few seconds, can cause seal damage and must be avoided. Physical injury can
occur if mechanical seal fails.
The Model 3500XD pump is supplied with a cartridge mechanical seal as standard. Cartridge seals are
preset at the factory and require no field settings. Remove the holding clips prior to operation to correctly
set the seal. Refer to the manufacturer’s outline drawing and instruction manual for further information.
A fresh water flush is required to lubricate and cool the seal faces. Refer to the Operation section of this
manual for details on the seal flush system supplied with the pump.
