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
15 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 the kife of the
bearings. In cases of extreme temperature and loadings, the
bearings may be re-lubricated with a low viscosity grease,
once a year. 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 (21), 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 (12) and lockwashers
(11), and pull volute (1) from pedestal (3). The impeller (3),
u-cup (2) and O-ring (7) are now exposed for examination or
replacement.
To remove impeller (3), loosen impeller with a block of wood
and a hammer. The impeller threads are right hand and to
loosen, turn counter-clockwise. Examine impeller (3) and u-
cup (2), replace if required.
At reassembly, handle impeller carefully so as not to damage
the impeller inlet hub, which is a machined sealing surface
and any damage to this surface will destroy the u-cup (2).
Also make sure spring (4C) of shaft seal (4) is in place before
reassembling the impeller.
