Congratulations
You are now the owner of a Goulds Water Technology
pump. This pump was carefully inspected and subjected
to final tests before releasing for shipment. In order to
have maximum performance, please follow the simple
instructions in this manual.
Recommended Precautions
1. If there is a possibility of air being entrapped in the
pump casing, install an automatic venting device to
bleed off the air.
2. All electric motors require a magnetic starter with
current over-load protection.
3. Drain casing completely when servicing pump
handling volatile or harmful liquids. SEE CAUTION.
4. Avoid system pressures that may exceed one and
a half times the operating point selected from the
pump performance curve.
5. Should the fluid temperature rise more than 50ºF
above ambient, expansion joints must be installed on
both the suction and discharge ports to relieve any
stress on the pump casing.
6. All electrical wiring of the pump installation must
be done by a licensed electrician who will observe all
national and local electrical codes.
7. No modifications, additions or deletions should be
made to the pump, without prior approval of the
factory.
8. After servicing the pump, always install the coupling
guards and other safety devices as originally found
prior to disassembly.
9. In systems where shock wave pressures may be
generated, protective devices such as check valves/
gate valves etc., must be installed on discharge line
to prevent shock pressures from entering the pump
casing.
10. In systems containing discharge check valves, gate
valves, etc., pump will not prime against a closed
valve. Check the discharge valves making sure they
are open before attempting to prime pump.
11. Overheated pumps are dangerous. Burns or
explosion could occur due to steam pressure.
Operation pumps with suction and discharge closed
is one cause of severe overheating. If over-heating of
pump casing occurs: 1. Stop pump immediately.
2. Allow pump to cool. 3. Slowly and cautiously
vent pump.
12. Do not use in a combustible atmosphere.
13. Make daily checks of the tightness of suction and
discharge pipe, drain, filter plug and pump gaskets.
Operation should not proceed until all of the above
items have been checked and are tight.
14. This pump is designed primarily for water use.
Before pumping other liquids, READ CAREFULLY
THE FOLLOWING WARNING.
THE PERFORMANCE OF GOULDS
WATER TECHNOLOGY PUMPS
IS BASED UPON CLEAR, COLD,
FRESH WATER WITH SUCTION
CONDITIONS AS SHOWN ON
THE PERFORMANCE CURVE.
IF USED TO PUMP OTHER
LIQUIDS, PUMP PERFORMANCE
MAY DIFFER FROM RATED
PERFORMANCE BASED ON THE
DIFFERENT SPECIFIC GRAVITY,
TEMPERATURE, VISCOSITY, ETC.
OF THE LIQUID BEING PUMPED.
A STANDARD PUMP MAY NOT
BE SAFE FOR PUMPING ALL
TYPES OF LIQUIDS, SUCH AS
TOXIC, VOLATILE OR CHEMICAL
LIQUIDS, OR LIQUIDS UNDER
EXTREME TEMPERATURES OR
PRESSURES.
Please consult Goulds Water Technology catalogs as well as local
codes and general references to determine the appropriate pumps
for your particular application. Since it is impossible for us to
anticipate every application of an Goulds Water Technology pump,
if you plan to use the pump for a non-water application, consult
Goulds Water Technology beforehand to determine whether such
application may be proper or safe under the circumstances. Failure
to do so may result in property damage or personal injury.
