d) Verify that cables will not cut into pump
panels, piping, etc. Remove any items that
will be damaged or protect items with wood
blocks See
Figure 2-2
: Barrel Pump Lifting.
e) Establish that hoist is over center of gravity
f) Hoist unit (or pump) and dispose of it
Figure 2- 2: Barrel Pump Lifing
With pump and cradle mounted on
soleplates (after soleplates have been secured to
the foundation and, when applicable, grouted) see
that pump and equipment are undamaged and that
items that had been removed for lifting of pump have
been reinstalled (see section 4.6.2).
2.3.3 Multistage internal assembly: Cartridge
Barrel pump
Do not lift internal assembly by shaft
or by eyebolts in intermediate cover [1460]. Do not
attempt to remove assembly from shipping crate
without first removing sides and ends of container.
Failure to comply could result in bent shaft.
When the multistage internal assembly or the full
cartridge assembly is going to storage, handle it as
described under section 2.4. Comply with the
following procedure for uncrating and subsequent
handling:
1) Remove sides and end of box.
2) Remove fastenings that hold assembly to box
then remove plastic cover.
3) Place nylon strap or soft cable around the
intermediate cover [1460], near center of
assembly. The weight of the suction spacer
casing normally causes the inboard half of
assembly to be heavier than outboard half. If
there is not enough space between intermediate
cover [1460] and bottom of box for cable: (see
Cartridge Assembly Lifting Points
Figure 2-3
).
Figure 2- 3: Cartridge Assembly Lifting Points
a) Place another cable around balance drum
[6230] and attach it to hoist
b) Lift end of assembly just enough to place
cable around lifting point and install the
lifting cable
c) Lower assembly onto lifting cable and
remove cable from balance drum [6230]
d) Attach hoist to cable and start raising
assembly
e) Verify that hoist is above center of gravity of
assembly; if not, lower it and reset cable
f) Raise internal assembly from bottom of box
and transport assembly.
2.3.4 Multistage rotor
When the multistage rotor is going to storage,
handle it as described under section 2.4. Read the
following precautions before uncrating and for
subsequent handling.
1) Insure that load on pump shaft is equalized by
using two pick-up points: one at each end of
rotor normally between first and second
impellers from end, depending on center of
gravity one point might fall between second and
third impellers on light end.
2)
Do not lift rotor:
a) With one cable (or strap) at the balance
point
b) With strap around ends of shaft
c) By one end
d) When held in bind, however slightly, or
e) With pick-up point inboard of third impeller
from end.
