For pumps supplied with hollow shaft drivers and a
one-piece headshaft (headshaft couples below
sealing housing) proceed to step (a).
For pumps supplied with a two-piece headshaft
(headshaft couples above the sealing housing) or
solid shaft drivers, proceed to step (b) directly
skipping step (a).
a) Attach the headshaft to the lineshaft with a
coupling and tighten (left hand threads).
b) 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. (Note that W heads do not have a
bearing retainer at the top column flange).
c) If baseplate is not included use shims or wedges
between the pump and foundation to level the
pump. The shaft must be centered in the
discharge head.
See section 4.4.4 for coupling installation on solid
shaft drivers and section 4.2.1~4.2.4 for pump
leveling details
Installation of discharge head with the 4.5.1.5.2
enclosing tube
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.
For pumps supplied with hollow shaft drivers and a
one-piece headshaft (headshaft couples below
sealing housing) proceed to step (a). For pumps
supplied with a two-piece headshaft (headshaft
couples above the sealing housing) or solid shaft
drivers, proceed to step (b) directly skipping step (a).
a) Attach the headshaft to the lineshaft with a
coupling and tighten (left hand threads).
b) Attach the top enclosing tube to the column
enclosing tube and tighten (left hand threads).
c) Lift the discharge head over shaft and enclosing
tube then 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 alignment ring if
supplied to bottom of head. (W heads do not have
an alignment ring at the top column flange).
d) Use shims or wedges between the pump and
foundation to level the pump. The shaft must be
centered in the discharge head.
See section 4.4.4 for coupling installation on solid
shaft drivers and section 4.2.1~4.2.4 for pump
leveling details.
Installation of pumps that are shipped 4.5.2
fully assembled
Lifting 4.5.2.1
See lifting methods in section 2.3.
Equipment and tools required for 4.5.2.2
installation of a fully assembled pump
a) Mobile crane capable of hoisting and lowering the
entire weight of the pump and motor.
b) Cable slings 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.
Uncrating and cleaning of a fully 4.5.2.3
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.
