Motors may be supplied separately from the pumps.
It is the responsibility of the installer to ensure that
the motor is assembled to the pump and aligned as
detailed in section 4.5. Discharge head column
piping and the pump assembly are supplied either
separately or as fully assembled depending upon the
pump size and weight. If the parts are shipped
separately, it is the customer’s responsibility to install
and align the pump with driver to the satisfaction of
Flowserve’s installation instructions.

a) Two (2) mobile cranes capable of hoisting and
lowering the pump and/or motor.
b) Two (2) steel clamps of suitable size.
c) Two (2) sets of chain tongs & cable sling for
attaching to the pump and motor lifting eyes.
d) Pipe clamp for lifting bowl assembly and the
column pipe. Approximately 4.5 m (15 ft) of 19
mm (3/4 in.) diameter rope may be required.

wrenches, socket set, screwdrivers, Allen
wrenches, wire brush, scraper and fine emery
cloth.

steel and light machinery oil.
Parts and accessories may be placed

individual packages. Inspect all containers, crates
and skids for attached parts before discarding.
Uncrating and cleaning of unassembled 4.5.1.3
pump
a) Clean the parts of any dirt, packing material and
other foreign matter.
b) Flush the pump inside and outside with clean
water. Clean all machined surfaces.
c) Remove any rust spots found on the machined
surfaces with fine emery cloth.
d) Clean all threaded connections and any accessory
equipment.
Lineshaft when shipped separately
should be left in the crate to avoid damage or loss of
straightness.
Installing the bowl and column 4.5.1.4
assembly
a) Sump and piping should be thoroughly cleaned
of all loose debris before starting installation.
b) Check all bolts for tightness.
c) Do not lift or handle the bowl assembly by the
pump shaft.
d) When installing bowl assemblies in sizes of 152
mm (6 in.) or 203 mm (8 in.), leave bowl securely
fastened to the wooden skid that is attached for
shipping until the bowl assembly is raised to a
vertical position. This will help prevent breaking
the bowls or bending the shaft.
e) If a strainer is to be used, attach it to the bowl
assembly using fasteners as necessary..
f) Position lifting equipment so it will center over the
foundation opening.
g) If a base plate is used, level the plate to 0.16 mm
per m (0.002 in. per ft) and then grout and anchor
in place.
h) Check for axial clearance or endplay and record
that number for future reference (while bowls are
in a horizontal position you should be able to push
or pull the pump shaft indicating axial clearance).
i) Carefully lift the suction barrel and the bowl
assembly with suitable straps or clamps (See
section 2.4 for lifting and safety rules).
j) Lower the bowl assembly into the well or sump.
Set clamp or holding device that is attached to
bowls on a flat surface. This is to stabilize bowl
assembly and reduce possibility of cross threading
the shaft.
k) Proceed to install the column assembly (refer to
specific column pipe drawings).
