LUBRICATING BEARINGS
Bearings must be lubricated properly in
order to prevent excess heat generation,
sparks and premature failure.
l
!
CAUTION
Pumps are shipped without oil.
Oil Lubrication: Fill bearing frame with oil, through
filler connection (located on top of bearing frame refer
to Fig. 34), until oil level reaches the middle of the
sight-glass. A high quality turbine type oil with rust
and oxidation inhibitors should be used. See
Table 5
for recommendations.
Pure Oil Mist Lubrication: Oil mist is an optional
feature for the ANSI family pumps. Follow oil mist
generator manufacturer’s instructions. The inlet
connections are located on the top of the bearing
frame, connection points are covered under
lubrication. (Refer to
Appendix I on converting
lubrication.)
Grease Lubrication: Pumps are shipped with
grease. See Table 6 for grease requirements.
Greased For Life Bearings: These bearings are
filled with grease and sealed by the bearing
manufacturer.
If the pump is put into operation after a prolonged shut
down, flush out the bearings and bearing frame with a
light oil to remove contaminants. During flushing,
rotate the shaft slowly by hand. Finally, flush the
bearing housing with proper lubricating oil to insure oil
quality after cleaning.
See Preventive Maintenance section for lubrication
recommendations.
l
! CAUTION
Operation of the unit without proper lubrication
will cause bearing failure, and pump seizure.
SHAFT SEALING
The mechanical seal used in an ATEX
classified environment must be properly
certified.
Cartridge Mechanical Seals:
1. Slide the cartridge seal onto the shaft or sleeve
until it contacts the inboard labyrinth oil seal.
2. Assemble the seal chamber per the instructions in
Section 6 - Disassembly & Reassembly .
3. Slide the cartridge seal into the seal chamber and
secure using the four studs and nuts.
4. Continue the pump reassembly per the
instructions in
Section 6 - Disassembly &
Reassembly .
5. Set the impeller clearance per the instructions in
Section 4 - Operation .
6. Tighten the set screws in the seal locking ring to
secure the seal to the shaft.
7. Remove the centering clips from the seal.
Conventional Inside Component Mechanical Seal:
1. Assemble the seal chamber per the instructions in
Section 6 - Disassembly & Reassembly .
2. Apply bluing to the shaft/sleeve at the face of the
seal chamber.
3. Continue the complete reassembly of the pump,
less the mechanical seal.
4. Set the impeller clearance per the instructions in
Section 4 - Operation .
5. Scribe a line on the blued shaft/sleeve at the face
of the seal chamber.
6. Remove the casing, impeller, and seal chamber
per the instructions in
Section 6 - Disassembly &
Reassembly .
7. Slide the gland (with the stationary seat and gland
gasket installed) onto the shaft until it contacts the
inboard labyrinth oil seal.
8. Install the mechanical seal rotary unit per the
manufacturer’s instructions using the scribed line
and the seal reference dimension.
