Congratulations
You are now the owner of a Goulds pump. This pump
was carefully inspected and subjected to fi nal tests before
releasing for shipment. In order to assure maximum
performance, please follow the simple instructions in this
manual.
RECOMMENDED PRECAUTIONS
1.
Avoid system pressures that may exceed the maxi-
mum working pressure of the pump.
2.
Should the fl uid 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.
3.
All electrical wiring of the pump installation must be
done by a licensed electrician who will observe all
national and local electrical codes. All motors require
a magnetic starter with current overload protection.
4.
No modifi cations, additions or deletions should be
made to the pump, without prior approval of the
factory.
5.
In systems where shock wave pressures may be gener-
ated, protective devices such as check valves/gate
valves, etc., must be installed on the discharge line
to prevent shock pressures from entering the pump
casing.
6.
In systems containing discharge check valves, gate
valves, etc., the pump will not prime against a closed
valve. Check the discharge valves making sure they
are open before attempting to prime the pump. If
there is a possibility of air being entrapped in the
pump casing, install an automatic venting device to
bleed off the air.
7.
This pump is designed primarily for water use. Before
pumping other liquids, read carefully the
CAUTION
below.
8.
Overheated pumps are dangerous. Burns or explosion
could occur due to steam pressure. Operating pumps
with suction and discharge closed is one cause of
severe overheating. If overheating of the pump occurs:
1. Stop pump immediately, 2. Allow pump to cool, 3.
Slowly and cautiously vent pump.
9.
Drain casing completely when servicing pumps han-
dling volatile or harmful liquids.
10.
Do not use in a combustible atmosphere.
11.
Make daily checks of the tightness of suction and
discharge pipe, drain, fi lter plug and pump gaskets.
Operation should not proceed until all of the above
items have been checked and are tight.
12.
After servicing the pump, always install the coupling
guards, belt guards and other safety devices as origi-
nally found prior to disassembly.
The performance of Goulds pumps are
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
specifi c 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 your Goulds Pumps catalog
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 applica-
tion of a Goulds pump, if you plan to use the pump for a
non-water application, consult Goulds Pumps beforehand
to determine whether such application may be proper
or safe under the circumstances. Failure to do so could
result in property damage or personal injury.
OPERATING INSTRUCTIONS
GENERAL
• Our shipping container has been specifi cally designed
to prevent transit damage. However, any indications
of damage or shortage should be carefully noted on
the delivery ticket and a claim fi led promptly with the
carrier.
PROPER LOCATION
• By placing your Goulds pump on a fi rm, level founda-
tion or between fi rmly supported pipelines, you reduce
harmful vibrations and unnecessary noises.
• While EV series pumps are self-priming and may be
located above the source of liquid supply, best pump
operation is obtained by locating the pump as close as
possible to the liquid being handled, keeping in mind a
pump can push liquid more effectively than it can pull
or draw liquid. Provide the necessary space around the
pump for future inspection and servicing of the unit.
PIPING
• All piping should be independently supported to elimi-
nate excessive strain on the pump. Avoid unnecessary
friction losses. Keep your piping as short as possible
and use the fewest possible elbows and fi ttings. Pipe
joint compound that will not dissolve in the liquid
being pumped should be used on all joints. Gate valves
combined with unions or fl anges, on both sides of the
pump, will facilitate pump removal without disturbing
the piping. It is occasionally advantageous to use suc-
tion pipe one size larger than that for which the pipe
is fi tted. Eccentric reducers should be used to change
pipe sizes.
STRAINER ADVISABLE
• Protect your investment. Install a strainer on the suc-
tion line. This will eliminate clogging of the pump,
poor performance and excessive wear. A 16 mesh
strainer submerged one foot below the liquid level is
adequate for EV series pumps. In-line strainers are
available from your Goulds Pumps dealer. Piping that
has a continuous rise will facilitate draining the system.
VALVES
• Install a check valve on the discharge side of the pump.
This will prevent high surge back pressures from
damaging the pump. If the pump is disconnected this
check valve will prevent the liquid from draining the
discharge line.
• Some installations may require the throttling of the
pump. Gate valves may be used on the discharge side.
Place the check valve between pump and gate valve.
