2. MAXIMUM INLET PRESSURE
The following table shows the maximum permissible
inlet pressure. However, the actual inlet pressure +
pressure against a closed valve must always be lower
than the maximum permissible operating pressure.

4. TEMPERATURE CAPABILITY
The SSV pump is capable of pumping liquids within
the below temperature range:
1-4SV -22º F to 250º F (-30º C to 120º C)
33SV-92SV -22º F to 250º F (-30º C to 120º C)
NOTE: In order to provide adequate cooling for the
electric motor, the ambient temperature must
be 32º F to 104º F and the relative humidity at
104º F must not exceed 50%.
For temperatures above 104º F and for installations
sites located at elevation in excess at 3000 feet above
sea level it may be necessary to derate the motor
performance. Please contact your distributor/dealer for
assistance.

5. MINIMUM NOMINAL FLOW RATE

To prevent overheating of the internal pump com-
ponents, make sure that a minimum water fl ow is
always guaranteed when the pump is running.
For continuous operation the minimum fl ow rate
recommended is specifi ed below.

NOTE: If this cannot be archived, then a bypass/
recirculate line is recommended.
Do not run the pump against a closed

discharge for longer than a few seconds.
6. NUMBER OF STARTS PER HOUR
For electric pumps coupled to motors supplied by
Goulds Pumps, the maximum number of work cycles
(starts and stops) in one hour are as follows:
HP 3 / -3
4
# of Starts 5
For more details, refer to technical manual.
If you use a different motor from
WARNING
the standard one supplied by Goulds
Pumps, please consult with the motor manufacturer
to fi nd out the maximum number of work cycles
allowed.
7. POWER SUPPLY REQUIREMENTS
Make sure that the supply voltages
WARNING
and frequencies are suited to the
characteristics of the electric motor. Check the
motor rating plate.
In general, the supply voltage tolerances for motor
operation are as follows:

1. TRANSPORTATION AND HANDLING OF
PACKED PRODUCT
The SSV pump is packed in cartons or wooden
crates having different dimensions and shapes.
Some cartons (the supporting base
WARNING
is made of wood) are designed to be
transported and handled in the vertical position.
Other cartons, as well as the wooden crates, are
designed to be transported and handled in the hori-
zontal position. Protect the product against humid-
ity, heat sources and mechanical damage (collisions,
falls, ...). Do not place heavy weights on the cartons.
