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

-º F to 50º F (-30º C to 10º C)

33SV-9SV

-º F to 50º F (-30º C to 10º C)

NOTE: In order to provide adequate cooling for the

electric motor, the ambient temperature must

be 3º 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.

WARNING

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

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:

-3

5-10

15-20 25-75

# of Starts

For more details, refer to technical manual.

If you use a different motor from

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

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

±%

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.
