SECTION B: GENERAL INFORMATION
B-1) To the Purchaser:
Congratulations!
You are the owner of one of the fi nest
pumps on the market today. Barnes® Pumps are products
engineered and manufactured of high quality components.
Over one hundred years of pump building experience
along with a continuing quality assurance program combine
to produce a pump which will stand up to the toughest
applications.
This manual will provide helpful information concerning
installation, maintenance, and proper service guidelines.
B-2) Receiving:
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, fi le a claim
immediately with the company that delivered the pump. If
the manual is removed from the packaging, do not lose or
misplace.
B-3) Storage:
Short Term-
Barnes pumps are manufactured for effi cient
performance following short inoperative periods in storage.
For best results, pumps can be retained in storage, as factory
assembled, in a dry atmosphere with constant temperatures
for up to six (6) months.
Long Term-
Any length of time exceeding six (6) months, but
not more than twenty four (24) months. The units should be
stored in a temperature controlled area, a roofed over walled
enclosure that provides protection from the elements (rain,
snow, wind-blown dust, etc.), and whose temperature can be
maintained b40 deg. F and +120 deg. F.
If extended high humidity is expected to be a problem, all
exposed parts should be inspected before storage and all
surfaces that have the paint scratched, damaged, or worn
should be recoated with a water base, air dry enamel paint.
All surfaces should then be sprayed with a rust-inhibiting oil.
Pump should be stored in its original shipping container. On
initial start up, rotate impeller by hand to assure seal and
impeller rotate freely.
B-4) Service Centers:
For the location of the nearest Barnes Service Center, check
your Barnes representative or Crane Pumps & Systems, Inc.
Service Department in Piqua, Ohio, telephone (937) 778-8947
or Crane Pumps & Systems Canada, Inc., in Bramton, Ontario
(905) 457-6223.
SECTION C: INSTALLATION:
C-1) Location:
The pump should be located as near as possible to the liquid
to be pumped and in no case should the pump be more than
25 feet above the surface of the liquid supply. The pump
should always be as level as possible.
C-2) Suction System:
Connect suction pipe or hose to suction inlet. If hose is used,
it should be of the reinforced type to prevent collapsing under
suction. Make sure all suction system connections are tight
and free of air leaks, as even a very slight leak will greatly
reduce priming ability and pumping effi ciency.
CAUTION! - This pump should not be operated
without a strainer on the end of the suction line
to prevent sticks, stones, rags and other foreign
matter from being drawn into the impeller. The
strainer should be cleaned regularly to insure full fl ow.
C-3) Discharge System:
Connect discharge hose or pipe to discharge opening in
pump.
C-4) Lubrication:
The pump requires no lubrication. It is equipped with a
mechanical shaft seal which is lubricated by the liquid being
pumped. The pump is equipped with ball bearings which
have been pack with lubricant at the factory. Under average
condition, the grease used is normally good for 5,000 hours
or one year, whichever comes fi rst. The bearings should then
be repacked per Section E-3.
CAUTION! - DO NOT operate pump without liquid
in the pump body as operating pump dry will
result in damage to the seal.
SECTION D: OPERATION:
D-1) Priming:
Prime pump by fi lling volute and suction line completely with
liquid. Allow air to escape by loosening plug (5), in top of
volute (1). Make sure all the air is out of the suction line and
volute, or pump will not prime properly. Pump requires foot
valve for priming or fl ooded suction. In freezing weather, the
pump should be primed with warm water if possible. If the
pump has been pumping liquid containing a considerable
amount of foreign matter, it is advisable to fl ush the foreign
matter out of the body before refi lling with liquid.
SECTION E: PUMP SERVICE AND REPAIR:
E-1) Impeller Service:
To service or clean impeller, disconnect suction and
discharge piping. Remove hex nuts (4) and lockwashers
(3), and pull volute (1) from seal plate (15). The impeller (8),
screw (9) washer (10) wear ring (6) and o-ring (13) are now
exposed for examination or replacement.
To remove impeller (8), hold pulley or coupling so shaft
will not move and remove impeller screw (9), washer (10),
impeller (8) and wear ring (6). Impeller screw (9) threads are
right hand and to loosen, turn counter-clockwise. Examine
impeller and wear rings (9) and (11), replace if required.
E-2) Shaft Seal Service:
To expose the seal for examination or replacement,
remove volute and impeller as outlined in Section E-1.
Remove rotating member (12A) from shaft sleeve (14). All
of the components of the shaft seal are now exposed for
examination or repair. If any part of the shaft seal shows wear
or damage, replace entire seal assembly.
When stationary member (12B) needs replaced, remove cap
screws (18), lockwashers (19), and pull seal plate (15) from
pedestal (17). Press used stationary member (12B) from seal
plate.
