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 flow is always guaranteed when the pump is running.

For continuous operation the minimum flow rate recommended is specified below.

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:

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

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.
