b) Ensure the pump and piping is clean. Before
putting the pump into operation, the piping should
be thoroughly back flushed to remove any foreign
matter which may have accumulated during
installation. Take all possible care not to
contaminate your system.
c) Install suction strainer if required. (See Section
4.6.2.1).
d) Fill the bearing housing with the appropriate oil to
the correct level. Bearing must receive a small
amount of oil prior to starting to ensure adequate
lubrication at start up. (Refer to Section 5.1.1).
e) Turn pump rotor by hand or with a strap wrench
to make sure it turns smoothly.
f) Assure that correct seal piping has been installed
and has not been damaged.
g) Prior to coupling installation, bump start motor to
check for correct rotation. If rotation is not correct
refer to motor manual for appropriate connections
to change rotation (Shut down all power prior to
change).
h) Ensure coupling is correctly aligned and
lubricated, and pump and driver is satisfactorily
doweled. (Refer to Section 4.5).
i) Ensure coupling guard is correctly installed.
The unit must not be operated unless
coupling guard is securely and completely bolted
in place. Failure to observe the warning could
result in injury to operating personnel.
j) Check torque of all bolting and the plugs for
tightness
5.1.1 Lubrication
Lubrication of bearing is by oil circulation into the
bearing housing provided by oil ring, slinger or pure
oil mist. A constant level oiler is normally furnished
(except for pure oil mist lubrication) with the pump
unless otherwise specified.
5.1.1.1 Oil ring or Slinger Lubrication
Before filling the bearing housing reservoir, flush out
the housing thoroughly with safety solvent and a
leading grade of flushing oil, compatible with the
lubricating oil that will be used. The reservoir is to be
filled to appropriate level as illustrated in section
5.1.1.1.5
Figure 5.1
Figure 5.1

C1: overflow plug with slinger lubrication
D2: oiler connection with oil ring lubrication
C2: overflow plug with oil ring lubrication
The oil level must be maintained at the correct level:
oil lack may cause overheating and failure of the
bearings, while exceeding the correct level can result
in leakage from the labyrinth seals. The constant
level oiler can be adjusted by changing the height of
the cross arms which support the glass reservoir, as
illustrated for TRICO oiler in section 5.1.1.1.1
The oil circulation is ensured by slinger or oil ring
according to the description as follow (see figure 5.2).
Line bearing side lubrication
•
(1)-(2) the slinger (or oil ring if supplied) splash
the oil from the oil sump to the bearing housing
walls
•
(3)-(4) the oil is collected by the oil collector and
reaches the line bearing through the hole “E”
•
(5) the oil returns into the oil sump once it flows
into the line bearing
Thrust bearings side lubrication
•
(1)-(2) the slinger (or oil ring if supplied) drives
the oil from the oil sump to the bearing housing
wall
