considered in storage when it has been delivered to the
job site and is awaiting installation. If a pump has been
installed, but is not in regular operation, such as seasonal
shutdown or an extended period of time, it is suggested
that the pump be operated for at least 15 minutes every
two weeks if possible.
2–3 RECOMMENDED STORAGE PROCEDURES
1. Controlled storage facilities should be maintained at
an even temperature 10º F (5.6°C) or more above the
dew point with relative humidity less than 50% and
little or no dust. (If these requirements cannot be met
the pump is to be considered in uncontrolled storage.)
2. For uncontrolled storage periods of six months or less,
the pump is to be inspected periodically to insure that
all preservatives are intact.
3. All pipe threads and flanged pipe covers are to be
sealed with tape.
4. The pump must not be stored closer than six inches to
the ground.
2–4 PREPARATIONS FOR UNCONTROLLED
LONG TERM STORAGE
Storage periods over six months require the preceding
uncontrolled storage procedure plus the following:
1. Inspect the assembly and recoat periodically to prevent
corrosion.
2. Place ten pounds of moisture absorbing desiccant or
five pounds of vapor phase inhibitor crystals near the
center of the pump. If the pump is assembled, place an
additional one pound in the discharge nozzle securely
fastened to the discharge flange.
3. Install a moisture indicator near the perimeter of the
pump. Cover the pump with 6 mils (0.15 mm) mini-
mum thickness black polyethylene or equal and seal
it with tape. Provide a small ventilation hole approxi-
mately ½ inch diameter.
4. Provide a roof or a shed shelter to protect from direct
exposure to the elements.
SECTION 3 — GENERAL DESCRIPTION
3–1 GENERAL DESCRIPTION
Goulds Water Technology model VS pump is a submers-
ible turbine pump designed for maximum dependability.
See Figure 1 for typical VS pump.
3–2 DRIVERS
Goulds Water Technology furnishes only internationally
recognized motors designed for continuous operation
under any thrust which may develop throughout the
performance curve. Impeller adjustment and type of
coupling, splined or clamped, is dependent on the
specific motor being used.
3–3 DISCHARGE
The discharge bowl provides an NPT or BSP thread for
connecting to the well head or the first section of column
pipe.

3–4 BOWL ASSEMBLY
The bowls are generally flanged construction for accurate
alignment and ease of assembly and disassembly. Impel-
lers may be enclosed or open type. Impeller position is
set at factory. No field adjustment is required.
