Goulds Pumps 3408A - IOM - Manual (Page 17)

LOCATION
Locate the pump so there is sufficient room for inspection,
maintenance, and service. If the use of a hoist or tackle is
needed, allow ample head room.
s
! WARNING
Falling Objects Hazard
Eyebolts or lifting lugs, if provided are for lifting only
the components to which they are attached.
Failure to follow these instructions could result in
serious personal injury or death, or property damage.
If lifting of the entire pump is required, do so with slings
placed under the base rails as shown in Figure 3.
The best pump location for sound and vibration absorption
is on a concrete floor with subsoil underneath. If the pump
location is overhead, special precautions should be
undertaken to reduce possible sound transmission. Consult
a sound specialist.
If the pump is not on a closed system, it should be placed as
near as possible to the source of the liquid supply and
located to permit installation with the fewest number of
bends or elbows in the suction pipe.
Figure 3: Lifting the Pump
The installation must be evaluated to determine that the Net
Positive Suction Head Available (NPSHA) meets or
exceeds the Net Positive Suction Head Required (NPSHR),
as stated by the pump performance curve. See the section
entitled Suction and Discharge Piping for more details
regarding proper suction piping installation.
s
! WARNING
Do not install and operate pumps, 3D valves, suction
diffusers, etc., in closed systems unless the system is
constructed with properly sized safety devices and
control devices. Such devices include the use of
properly sized and located pressure relief valves,
compression tanks, pressure controls, temperature
controls, and flow controls as appropriate. If the
system does not include these devices, consult the
responsible engineer or architect before making pumps
operational.
