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:
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 flow is always guaranteed when the pump is running.
For continuous operation the minimum flow rate recommended is specified below.
Pump Size | 1SV | 2SV | 3SV | 4SV | |
Min. Flow | 3500 RPM | 3 | 6 | 12 | 17 |
(gpm) | 2900 RPM | 3 | 6 | 10 | 14 |
|
|
|

|
|
Pump Size | 33SV | 46SV | 66SV | 92SV | |
Min. Flow | 3500 RPM | 35 | 40 | 70 | 100 |
(gpm) | 2900 RPM | 8 | 10 | 14 | 20 |
NOTE: If this cannot be archived, then a bypass/ recirculate line is recommended.
| Do not run the pump against a closed |
WARNING | |
| 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 | ||||
# of Starts | 5 | 5 | 5 | 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 find out the maximum number of work cycles allowed.
7. Power Supply Requirements
WARNING 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:
| Hz | Phase |
| UN | ||
| V |
| ±% | |||

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.
