PUMP IDENTIFICATION
The size and type designation of ITT Industries - Goulds Pump
rubber-lined pumps includes the suction and discharge
diameters and the nominal impeller diameter. For example, a
12x10x25 SRL-C pump has a 12" suction, a 10" discharge and
a 25" diameter closed impeller.
INSPECTION
RECEIVING PUMP
Check pump for damage and material shortages after arrival.
Prompt reporting to the carrier’s agent, with notations made on
the freight bill, will expedite satisfactory adjustment by the
carrier.
2. Unload and handle the unit carefully.
NOTE: HOLES ON CAS ING LUGS ARE USED TO
LIFT CAS ING HALVES ONLY. DO NOT USE
FOR LIFT ING ENTIRE UNIT.
TEMPORARY STORAGE
If the pump is not to be installed and operated soon after
arrival, store it in a cool, dry and dark place, ideally 50°—70° F
(10°- 21° C) with a maximum of 100° F (38° C). If stored
below 32° F (0° C), some rubber products may become stiff
and should be warmed before being placed in service. Do not
store near electrical equipment which may generate ozone or in
areas of known high ozone. Avoid direct or reflected sunlight.
Certain insect and rodents thrive on rubber products so
adequate protection should be provided. Rubber should not be
stored in areas of high or low humidity. Oils, solvents,
corrosive liquids and fumes could also adversely affect the
rubber.
Rotate the shaft periodically to coat the bearings with lubricant
and to retard oxidation and corrosion.
FOUNDATION
FOUNDATION
The foundation should be sufficiently substantial to absorb any
vibration, and to form a permanent rigid support for the pump.
A concrete foundation, with foundation bolts of the proper size
grouted in place to drawing dimensions, is recommended.
MOUNTING OF PUMP
The foundation surface will support the pump with sole-plates
under the frame at the foundation bolts. The sole-plates can be
set in a puddle of grout and should be leveled in all directions,
and in relation to each other. This will ensure a minimum
amount of shimming necessary to completely level the pump.
Tighten the foundation bolts evenly and recheck for all round
levelness of the pump.
PIPING
Note that piping should not be connected to pump until unit has
been set per instructions and grouted in.
1. Support piping close to, but independently of pump.
2. Keep piping as straight as possible, with few or no bends
and fittings.
3. Remove burrs, sharp edges, ream pipe cuts, and make joints
air tight.
4. Do not “spring” pipes to make connection. Strain must not
be transmitted to pump.
SUCTION PIPE
1. The suction pipe should be as short as possible, containing a
minimum number of fittings. It should be so arranged that one
section may be readily removed to allow the dismantling of the
suction half casing. Victaulic or similar type couplings are
recommended for this section of the pipe to facilitate
dismantling. The suction pipe should slope upwards to the
pump nozzle.
2. Suction line inlet in the sump must be flooded at all times,
even if it necessary to install the pumps so that a suction lift is
involved. The pump must never be throttled by the use of a
valve on the suction side of the pump. It is advisable to have a
shut-off valve in the suction line so that the pump can be
isolated while repairs are being made, but this valve should
never be used to control the capacity of the pump by throttling.
DISCHARGE PIPE
On long horizontal runs, it is desirable to maintain as even a
grade as feasible. Avoid high spots, such as loops, which will
collect air and throttle the system or lead to erratic pumping
or surging.
