5. TEMPERATURE CAPABILITY
The e-SV pump is capable of pumping liquids within
the below temperature range:
Standard Seal
1SV-22SV
-22°F to 250°F (-30°C to 120°C)
33SV-125SV
-22°F to 250°F (-30°C to 120°C)
High Temperature Seal
1SV-22SV
-22°F to 340°F (-30°C to 171°C)
33SV-125SV
N/A
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.
6. MINIMUM NOMINAL FLOW RATE
To prevent overheating of the internal pump com-
ponents, make sure that a minimum water flow is
always guaranteed when the pump is running.
For continuous operation the minimum flow rate
recommended is specified below.

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

charge for longer than a few seconds.
7. NUMBER OF STARTS PER HOUR
For electric pumps coupled to motors supplied by
Goulds Water Technology, the maximum number
of work cycles (starts and stops) in one hour are as

* For more details, refer to technical manual.
If you use a different motor from the
WARNING
standard one supplied by Goulds Water
Technology, please consult with the motor manu-
facturer to find out the maximum number of work
cycles allowed.
8. POWER SUPPLY REQUIREMENTS
Make sure that the supply voltages 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 e-SV pump is packed in cartons
WARNING
or wooden crates having different
dimensions and shapes.
Some cartons (the supporting base 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 horizontal position. Protect the
product against humidity, heat sources and mechani-
cal damage (collisions, falls, ...). Do not place heavy
weights on the cartons.
