Pump Installation; Installing The Bowl Assembly - Goulds Pumps VIT Installation, Operation And Maintenance Instructions

9 Sylvan Way, Parsippany, NJ 07054-3802 and must be
reviewed prior to pump installation.
Never draw piping into place by forcing
WARNING
the flange connections of the pump. Pipe
strain will adversely effect the operation of the pump
resulting in damage to the equipment and possible
physical injury.
1. All piping must be supported independently of, and
line up naturally with the pump flange so that undue
pipe strain is not imposed on the pump.
2. DO NOT connect piping to pump until grout has
hardened and pump hold-down bolts have been
tightened.
3. It is suggested that expansion loops or joints, if used,
be properly installed in the discharge line. When
handling liquids at elevated temperatures expansion
joints are used, so linear expansion of piping will
not draw pumps out of alignment.
4. Carefully clean all pipe parts, valves and fittings, and
piping branches prior to assembly.
5. Isolation and check valves should be installed in
discharge line. Locate the check valve between
isolation valve and pump, this will permit inspection
of the check valve. The isolation valve is required
for regulation of flow, and for inspection and
maintenance of pump. The check valve prevents
pump or seal damage due to reverse flow through
the pump when the driver is turned off.
6. Increasers, if used, should be placed between pump
and check valves.
7. Cushioning devices should be used to protect the
pump from surges and water hammer if quick-
closing valves are installed in the system.

PUMP INSTALLATION

Pumps of 20 feet (6 meters) or less in length are usually
shipped assembled, with the exception of the driver,
mechanical seal with tubing and coupling assembly,
spacer or non spacer type. When provided, refer to the
Certified Pump Outline for the applicable base plate plan
for the location of anchor bolt holes.
INSTALLING AN ASSEMBLED PUMP
1. If a base plate was supplied, install as described in
Foundation/Piping Section (page 11).
2. Clean the mounting surface of the plate and clean
bottom surface of discharge head mounting flange.
3. Sling through discharge head holes or thread two
eyebolts through bolt holes in the mounting flange
and hoist unit into position over foundation.
NOTE: Eyebolts or sling should be rated to
handle in excess of the pump weight (See Outline
Drawing).
4. Lower the unit and carefully guide it so that unit
does not strike the side of the base plate. Continue
12
to lower unit until the discharge head flange engages
and rests firmly on the plate, then secure with
capscrews provided.
5. When a lineshaft is shipped separately check shaft
for straightness; average total run out should not
exceed 0.005" TIR (0.127mm) for 10 feet (3m).
Shaft must be within tolerance prior to installation.
6. Refer to remainder of this manual for complete
assembly, startup, maintenance, disassembly and
recommended lubricants for the pump.
INSTALLING A PARTIALLY ASSEMBLED PUMP
Do not work under a heavy suspended
WARNING
object unless there is positive support and
safe guards, which will protect personnel, should a hoist
or sling fail.
Do not attempt to lift bowl assembly
CAUTION
by the pump shaft. This can result in
damaging the pump shaft.
1. Prior to installing the bowl assembly, check that
all capscrews are tight. Turn the pump shaft by
hand and make sure it turns freely. Remove all
accumulated dust, oil or other foreign material from
the external surfaces.
2. Place two I-beam supports across the base plate
opening, strong enough to safely support the weight
of the entire pump assembly. These I-beams should
be connected by threaded rods and nuts so as to
clamp them firmly together to support the pump.
(See Figure 7).

3. Place a suitable hoist or derrick over base plate
opening with the hook in the center.
4. If a suction strainer is provided, assemble it to the
suction bell (or suction bowl).
5. Place the elevator clamps just below the discharge
bowl. For flanged column install two threaded
eyebolts through the discharge bowl bolt holes 180º
apart for flanged column. For threaded discharge
utilize a lifting bail sized to handle the weight of the
bowl assembly and suction apparatus.
