3 Installation
WARNUNG:
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 procee-
ding.
3.1 Site/Foundation
3.1.1 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.
WARNUNG:
All equipment being installed must be properly grounded to prevent unexpected static
electric discharge.
3.1.2 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).
3.2 Piping
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.
WARNUNG:
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 di-
scharge lines when handling liquids at elevated temperatures, so thermal expansion of piping
will not draw pump out of alignment.
3.
The piping should be arranged to allow pump flushing prior to removal of the unit on services
handling hazardous liquids.
4.
Carefully clean all pipe parts, valves and fittings, and pump branches prior to assembly.
5.
All piping must be supported independently of, and line up naturally with, the pump flanges.
Table below shows piping flange alignment criteria.
