2.3.2 Lifting pump, motor and baseplate assembly
2.3.2.1 Horizontal assemblies
If the baseplate has lifting holes cut in the sides at the
end (Type A Group 3, Type D and Type E bases) insert
lifting S hooks at the four corners and use slings or
chains to connect to the lifting eye. (Figure 2-1.) Do not
use slings through the lifting holes.
For other baseplates, sling around the pump discharge
nozzle, and around the outboard end of the motor frame
using choker hitches pulled tight. (Figure 2-1.)
The sling should be positioned so the weight is not
carried through the motor fan housing. Make sure the
completion of the choker hitch on the discharge
nozzle is toward the coupling end of the pump shaft
as shown in figure 2-1.
2.3.2.2 In-Line assemblies
If the pump is to be lifted as a complete assembly, the
motor lifting lugs must be used to ensure that the
assembly does not flip over. Check with motor
supplier for lifting lug capacities. If there is any
uncertainty, the motor should be removed prior to
moving the pump. (Figure 2-2.)
2.4 Storage
Store the pump in a clean, dry location
away from vibration. Leave flange covers in place to
keep dirt and other foreign material out of pump
casing. Turn the pump shaft at regular intervals to
prevent brinelling of the bearings and the seal faces,
if fitted, from sticking.
The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions
when a longer storage period is needed.
2.4.1 Short term storage and packaging
Normal packaging is designed to protect the pump
and parts during shipment and for dry, indoor storage
for up to six months or less. The following is an
overview of our normal packaging:
• All loose unmounted items are packaged in a
water proof plastic bag and placed under the
coupling guard
• Inner surfaces of the bearing housing, shaft (area
through bearing housing) and bearings are coated
with Cortec VCI-329 rust inhibitor, or equal.
Bearing housings are not filled with oil
prior to shipment
• Regreasable bearings are packed with grease
(EXXON POLYREX EM for horizontal pumps and
EXXON UNIREX N3 for In-Line pumps)
• The internal surfaces of ferrous casings, covers,
flange faces, and the impeller surface are
sprayed with Cortec VCI-389, or equal
• Exposed shafts are taped with Polywrap
• Flange covers are secured to both the suction
and discharge flanges
• In some cases with assemblies ordered with
external piping, components may be
disassembled for shipment
• The pump must be stored in a covered, dry location
2.4.2 Long term storage and packaging
Long term storage is defined as more than six
months, but less than 12 months. The procedure
Flowserve follows for long term storage of pumps is
given below. These procedures are in addition to the
short term procedure.
• Each assembly is hermetically (heat) sealed from
the atmosphere by means of tack wrap sheeting
and rubber bushings (mounting holes)
• Desiccant bags are placed inside the tack
wrapped packaging
• A solid wood box is used to cover the assembly
This packaging will provide protection for up to twelve
months from humidity, salt laden air, dust etc.
