Goulds Pumps 3408A - IOM - Manual (Page 19)

GENERAL INSTRUCTIONS
PURPOSE OF THE MANUAL
This manual is furnished to acquaint you with some of the
practical ways to install, operate, and maintain this pump.
Read it completely before any installation, operation, or
maintenance on your unit and keep it handy for future
reference.
Equipment cannot operate well without proper care. To
keep this unit at top efficiency, follow the recommended
installation and servicing procedures outlined in this
manual.
WARRANTY
Refer to your local representative for warranty coverage.
RECEIVING THE PUMP
Check the pump for shortages and damage immediately
upon arrival. (An absolute must!) Prompt reporting of any
damage to the carrier’s agent, with notations made on the
freight bill, will expedite satisfactory adjustment by the
carrier.
Pumps and drivers are normally shipped from the factory
mounted on a base plate and painted with primer and one
finish coat. Couplings may either be completely assembled
or have the coupling hubs mounted on the shafts and the
connecting members removed. When the connecting
members are removed, they will be packaged in a separate
container and shipped with the pump or attached to the base
plate.
Shafts are in alignment when the unit is shipped; however,
due to shipping, the pumps may arrive misaligned.
Alignment must be established during installation. Goulds
Pumps has determined that proper and correct alignment
can only be made by accepted erection practices. (See the
Foundation, Baseplate Setting, and Coupling Alignment
sections.)
TEMPORARY STORAGE
If the pump is not to be installed and operated soon after
arrival, store it in a clean, dry place having slow, moderate
changes in ambient temperature. Rotate the shaft
periodically to coat the bearings with lubricant, to retard
oxidation and corrosion, and to reduce the possibility of
false brinelling of the bearings.
LOCATION
The pump should be installed as near the suction supply as
possible, but no less than five suction diameters with the
shortest and most direct suction pipe practical. See the
section entitled Suction and Discharge Piping. The total
dynamic suction lift (static lift plus friction losses in suction
line) should not exceed the limits for which the pump was
sold.
The pump must be primed before starting. Whenever
possible, the pump should be located below the fluid level
to facilitate priming and assure a steady flow of liquid. This
condition provides a positive suction head on the pump. It
may also be possible to prime the pump by pressurizing the
suction vessel.
When installing the pump, consider its location in relation
to the system to assure that sufficient Net Positive Suction
Head (NPSH) at pump suction is provided. Available
NPSH must always equal or exceed the required NPSH of
the pump.
The pump should be installed with sufficient accessibility
for inspection and maintenance. A clear space with ample
head room should be allowed for the use of an overhead
crane or hoist sufficiently strong to lift the unit.
NOTE: Allow sufficient space to be able to dismantle
the pump without disturbing the pump inlet and
discharge piping.
Select a dry place above the floor level wherever possible.
Take care to prevent the pump from freezing during cold
weather when not in operation. Should the possibility of
freezing exist during a shut-down period, the pump should be
completely drained, and all passages and pockets where liquid
might collect should be blown out with compressed air.
Make sure there is a suitable power source available for the
pump driver. If motor driven, electrical characteristics
should be identical to those shown on the motor data plate.
FOUNDATION
A substantial foundation and footing should be built to suit
local conditions. It should form a rigid support to maintain
alignment. The pump assembly must be mounted to a
suitable foundation having a mass
³ 1.5 times the weight of
the unit.
The foundation should be poured without interruption to
within 1/2 to 1-1/2 inches of the finished height. The top
surface of the foundation should be well scored and
grooved before the concrete sets; this provides a bonding
surface for the grout.
Foundation bolts should be set in concrete as shown in
Figure 4. An optional 4-inch long tube around the bolts at
the top of the concrete will allow some flexibility in bolt
alignment to match the holes in the base plate. Allow
enough bolt length for grout, shims, lower base plate
flange, nuts and washers. The foundation should be
allowed to cure for several days before the baseplate is
