c) Do not lift or handle the bowl assembly by the
pump shaft.
d) If a strainer is to be used, attach it to the bowl
assembly using clips and fasteners provided.
e) Position lifting equipment so it will center over the
foundation opening.
f) If a base plate is used, level the plate to 0.08 mm
per m (0.001 in. per ft) and then grout and anchor
in place.
g) 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).
h) Carefully lift the suction barrel and the bowl
assembly with suitable straps or clamps (See
section 2.4 for lifting and safety rules).
i) 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.
j) Proceed to install the column assembly (refer to
specific column pipe assembly instructions
supplied with the pump).
k) Assemble the discharge head.
4.1.2.5
Installation of discharge head
Pump head may be shipped with the sealing
housing installed. For ease of assembly and to
prevent damage, we recommend removing the
housing before putting the head on the pump.
a) Lift discharge head over shaft and lower carefully
into place
(See section 2.3 for recommended
lifting methods and safety instructions). Be sure
not to bend the shaft. Fasten the top column
flange and bearing retainer, if supplied to bottom
of head.
b) Use shims or wedges between the pump and
foundation to level the pump. The shaft must be
centered on the discharge head.
See section 4.1.5 for coupling installation on solid
shaft drivers and section 4.3.1~4.3.4 for pump
leveling details
4.1.3
Installation of pumps that are shipped
fully assembled
4.1.3.1 Lifting
See lifting methods in section 2.3.
4.1.3.2 Equipment and tools required for
installation of a fully assembled pump
a) Mobile crane capable of hoisting and lowering the
entire weight of the pump and motor.
b) Cable sling for attaching to the pump and motor
lifting eyes.
c) Ordinary hand tools: Pipe wrenches, end
wrenches, socket set, screwdrivers, Allen
wrenches, wire brush, scraper and fine emery
cloth.
d) Thread sealing compound designed for type of
connection and light machinery oil.
The single most common cause of pump
vibration is from a bent shaft. Shafting is
straightened to stringent tolerances prior to shipping
and great care must be exercised in its handling.
Always support shafting in at least three places when
lifting or installing.
Parts and accessories may be placed
inside shipping containers, or attached to skids in
individual packages.
Inspect all containers, crates and skids for attached
parts before discarding.
Lifting heavy objects is dangerous. Use of
appropriate tools and procedures is must.
4.1.3.3
Uncrating and cleaning of a fully
assembled pump
a) Clean the parts of all dirt, packing material and
other foreign matter.
b) Flush the pump inside and outside with clean
water.
c) Clean all machined surfaces. Remove any rust
spots found on the machined surfaces with fine
emery cloth.
d) Clean all threaded connections and any
accessory equipment.
4.1.3.4
Installing the fully assembled pump
If a base plate is used, level the plate to 0.08 mm per
m (0.001 in. per ft), grout and anchor in place.
See sections 4.3.1~4.3.4 for pump leveling details.
Position lifting equipment so it will center over the
foundation opening.
