!
When pumping unit is installed in a potentially explosive atmosphere, the instructions after the Ex symbol must be
followed. Personal injury and/or equipment damage may occur if these instructions are not followed. If there is any
question regarding these requirements or if the equipment is to be modified, please contact a Goulds representative
before proceeding.
LOCATION
Pumping unit should be placed as close as practical to the
source of supply. Floor space and head room allotted to
the unit must be sufficient for inspection and
maintenance. Be sure to allow for crane or hoist service.
!
All equipment being installed must be properly
grounded to prevent unexpected static electric
discharge.
Guidelines for piping are given in the "Hydraulic Institute
Standards," available from:
Hydraulic Institute
30200 Detroit Road
Cleveland, OH 44145-1967
and must be reviewed prior to pump installation.

! WARNING
Never draw piping into place by forcing at the
flanged connections of the pump. This may impose
dangerous strains on the unit and cause misalign-
ment between pump and driver. Pipe strain will
adversely affect the operation of the pump resulting
in physical injury and damage to the equipment.
1. Piping runs should be as short as possible to
minimize friction losses.
2. It is suggested that expansion loops be properly
designed and installed in suction and/or discharge
lines when handling liquids at elevated temperatures,
so thermal expansion of piping will not draw pump
out of alignment.

SITE/FOUNDATION
FOUNDATION AND BASEPLATE
Model 3996 In-Line pumps are designed to be mounted
directly in, and supported by the piping. No supports
under the pump are required. Pipe supports should be
located close to the pump and be designed to support the
weight of the complete unit (pump and motor).
PIPING

4.
5.
6.
The piping should be arranged to allow pump
flushing prior to removal of the unit on services
handling hazardous liquids.
Carefully clean all pipe parts, valves and fittings, and
pump branches prior to assembly.
All piping must be supported independently of, and
line up naturally with, the pump flanges. Table 2
shows piping flange alignment criteria.
Table 2
Piping Flange Alignment
Type
Flange gasket thickness ± 0.8 mm (.03 in.).
Axial
0.001 mm/mm (.001 in./in.) of flange
Parallel
diameter to a maximum of 0.8 mm (.03 in.).
Concentric Flange bolts should easily install by hand.
Bottom of casing should be supported by a solid
foundation or casing feet should be used.
