Recommendations, Warnings & Installation
Receiving inspection
Upon receiving the pump, it should
be inspected for damage or
shortages. If damage has occurred,
file a claim immediately with the
company that delivered the pump. If
the manual is removed from the
packaging, do not lose or misplace.
Storage
Any product that is stored for a
period longer than six (6) months
from the date of purchase should be
bench tested prior to installation. A
bench test consists of, checking the
impeller to assure it is free turning
and a run test to assure the motor
(and switch if provided) operate
properly.
Service Stations
To find the nearest Barmesa Pumps
authorized service shop, please
directly contact your distributor or
the factory.
The anchors of the motor are to be
anchor, on a raised base,
approximately 4", this to prevent
accumulated water from entering the
motor.
**See Friction Table in pipes and
fittings to determine the dimensions of
the suction and discharge.
At any time exceeding six (6) months,
but no more than twenty four (24),
the equipment must be stored in a
controlled area, keeping it away from
contact with rain, dust, etc., and the
temperature is maintained between
43-104 °F. If there is a possibility of
high humidity (coastlines, etc.), the
entire unit must be sprayed with
antioxidant liquid.
Installation
The pump should be as close as
possible to the liquid to be pumped,
with a minimum number of
couplings, adapters, etc., in order to
reduce friction on the suction side.
The suction and discharge piping
must be perfectly aligned in the
pump volute and supported
independently using support or
anchors, this to prevent excessive
load on the volute.
A successful operation depends on
the calculation of the friction loss in
the suction, considering acceptable
limits. The minimum suction pipe size
to use can be determined by
comparing the NPSH available at the
pump suction against the NPSH
required by the impeller, as shown in
the performance curves.
Usually, we recommend using a pipe
diameter of ½" to 1" greater as that of
the suction volute or body.

is combined with a strainer. (Figure 1)
Use pipe or hose reinforced
sufficiently robust to prevent
collapsing by the difference in
atmospheric pressure. Check for leaks
at all joints.

Discharge pipe
Because the cost of energy or BHP
necessary to overcome the friction
generated by using a smaller
diameter pipe, a larger diameter
discharge pipe is commonly used
than that required by the volute or
body.
barmesapumps.com

Due to the cost of energy or BHP
necessary to overcome the friction
generated by using a smaller
diameter pipe, a larger diameter
discharge pipe is commonly used
than the required by the volute or
body.
07
Installation & Operation
In order to determine the optimal
size of the piping, compare the total
cost of the equipment's operation
(cost of the pump, control
equipment, piping and energy
consumption). By increasing the
discharge diameter reasonably, it
reduces the required BHP due to the
low friction. Perform different tests
using several piping diameters until
you find the more convenient.
The pipe, valves, etc. should be
perfectly align with the volutes
suction and discharge centerlines,
this to avoid any excessive loads on
the pumps volute. If needed, install
new expansive joints to protect the
pump from excessive thermal or
pressure forces.

Sometimes air is trapped inside the
body, to remove it you should uncap
the male plug until the liquids spills
out. Re-install the male plug using a
sealant.
IMPORTANT! - Do not
operate pump without
priming first. Operating dry
will damage seal.
Pre-Operation
1.Check Voltage and Phase -
Compare the voltage and phase
information stamped on the
pump name plate.
2.Check Pump Rotation - Improper
motor rotation can result in poor
pump performance and can
damage the motor and/or pump.
Check rotation on three phase
units by momentarily applying
power and observe the "kickback".
4.Priming - Every centrifugal pump
must be primed (suction pipe and
pump´s body should have liquid),
before operating.
Kickback should always be in a
counter-clockwise direction as
viewed from motor end or opposite
to impeller rotation. Impeller rotation
is counter-clockwise as viewed from
bottom of pump.
3.Name Plate - Record the
information from the pump name
plate to drawing in front of manual
for future reference.
barmesapumps.com

Starting
When starting for the first time your
equipment check that the discharge
valve is 90% closed. Gradually open
the valve until the motor runs at full
load (amperage plate). Never allow
the amperage consumed by the
pump exceeds the maximum
permitted by the engine.
Mechanical Seal - To inspect or
replace the shaft seal, remove the
body and impeller. If any part shows
wear or damage, replace both parts
(stationary seat and rotary part). The
rotating seal parts may be stuck
together with the shaft, this happens
when the seal has been assembled
for a long time.
If the mechanical seal does not leak
and there is need to open the pump
for inspection or cleaning, DO NOT
remove the seal, remove the spring
only if the impeller needs to be
removed. Once a seal has been in
operation is very difficult to remove
and reassembly without creating a
seal leak.
IMPORTANT! - Always
unplug the pump before
applying maintenance,
service or repair to avoid
electric shock.
Handle seal parts with
extreme care. DO NOT
damage lapped surfaces.
08
Operation & Maintenance
Mechanical seal
Mechanical seals installed in this
pumps are lubricated by water,
therefore the pump should not be
operated dry. You will find the
appropriate seal for each use and
liquid to be pumped, check with your
Barmesa Pumps distributor for more
information.
Stuffing box*
If the pump has graphite packing
(stuffing box) consider the following:
ŸWhen the pump is placed into
operation, the liquid will drip from
the stuffing box; if this does not
happen, loosen the nuts on the
stuffing box until dripping occurs.
ŸOnce the pump has operated for a
reasonable period and the
dripping has not decreased to “a
few drops per minute", it is
necessary to tighten the nuts
stuffing box. If tightening the nuts
the required drip is not achieved,
the graphite packing rings must be
replaced.
ŸAfter a few minutes of operation,
gradually tighten the nuts until the
dripping decreases but not cease.
Frame*
All pumps come with factory
lubricated bearings. It is very
important to have oil in the oil tank.
(Use oil DTE26). Change the oil every
1,000 hours of operation, considering
a daily operation of 8 hours.
It is important not to overfill the oil
tank because it would cause an
increase in pressure by heating,
affecting the bearings and seals. In
normal operation, the frame
temperature increases 122 °F above
ambient temperature.
*For Barmesa pumps with universal
transmission.
Flexible coupling*
All pumps operated through flexible
coupling or by pulleys and belts must
be perfectly aligned to ensure
smooth operation. In no case
problems occur with flexible
couplings if the pump-motor
alignment is correct. All pumps are
manufactured following this
condition.
Maintenance
Body and Impeller - All pump parts
are removable by removing nuts and
bolts. For body maintenance,
disconnect the suction and
discharge, and remove the body of
the intermediate coupling. For
maintenance of the impeller is not
necessary to remove the suction or
discharge, simply remove the body
nuts; this would uncover the impeller.
Examine and replace if it shows wear
or damage.
When the impeller requires
replacement, remove the screw of
the shaft, and using a puller, remove
the impeller being careful not to
abuse the keyway of the shaft.
Disassembly
Mechanical Seal - Perform the steps
above. Remove the rotating part. It
may be necessary to remove the
intermediate link to remove the
stationary seat. To do this, remove the
nuts and washers that attach the
coupling to the motor. When
removing the coupling, the steady
part will move towards the front seat
of the shaft and the sleeve. If the seat
does not yield itself, push from the
rear of the coupling.
Reassembly
Mechanical Seal - Identify all parts of
Figures 7 and 8. The ring (6) and seat
(1) are perfectly polished, so care
must be taken not to scratch or
smudge. The cleaning during the
assembly process is very important.
IMPORTANT! - All parts
must be clean before
reassembly.

Service
Step 1: Install the intermediate
coupling if it was previously
removed. Make sure the shaft and
cavities, where will it seats, are clean.
The shaft sleeve should not be sharp,
but a radius of about 1/32”. It is
recommended that lightly polish the
area of the shaft. If the shaft and it
radius are perfectly polished, the seal
can be relatively easily installed.
Step 2: Install the seat assembly (1
and 2) on the inside of the
intermediate coupling, using an SAE
No. 90 oil in rubber parts. This
assembly should be done only
manually, meaning without the use
of an instrument.
Step 3: Install the rotating portion of
the seal without the spring. Lubricate
the shaft and the inside of the seal
with three or four drops of SAE No. 10
oil. With clean, dry hands, insert the
rotating portion to the shaft, sliding
it abuts the stationary seat. Once the
seal is in place, insert the spring (5).
Step 4: Place the impeller and
washers; tighten the hex screw.
Maintenance
Flexible Coupling - Universal type
pumps generally use 2 different types
of flexible couplings: the "Lovejoy"
type with rubber spider, and the
"Steelflex" type "F" with grids buffer.
The first mentioned coupling requires
no lubrication, the second does
require lubrication at least every
twelve months. If the second type of
coupling is exposed to excessive
moisture, extreme temperatures,
sudden loads applications, etc., it
should be lubricated more often. For
more information on the type of
lubricant consult your distributor.
Flexible Coupling
"Lovejoy" type - To remove, just
loosen the set screws on the hub. To
reinstall, align the shaft and tighten
the set screws. Should take in
consideration a clearance of 1/16"
(1.574 mm) between jaws. As
mentioned earlier, a good alignment
is essential for optimal operation.
"Steelflex" type - Identify the parts
in Figure 10. The most relevant issue
in the assembly of a coupling of this
type is the clearance point that
should be left between the hubs; to
determine this see Table 3.
Disassembly
Flexible Coupling
ŸSeparate coupling covers,
removing the nuts and bolts. Be
sure not to damage the seal.
ŸTo remove the grid, use a round
bar or a screwdriver to fit the
curves of the grid.
ŸInsert the tool into the open end of
the grid toward the curved end,
pry out gradually. Alternate
procedure on each side to pop out
half of the grating.
ŸRepeat for each side until it clears
the grid.
ŸIf you need to remove the hubs,
loosen the set screws if the model
has them.
Assembly
Flexible Coupling
ŸIf the hubs are removed, adjust
shaft shims.

Service
ŸMount hubs on the shaft, leaving
the faces flush with the shaft ends.
ŸTighten the set screws if the model
has them.
ŸDetermine the required clearance
using Table 3. Using a spacer bar
with the obtained thickness, insert
between the hubs at the the same
depth and in 90 ° intervals.
ŸUse a feeler gauge to measure the
gap between the space bar and
hub face. The difference between
the maximum and minimum must
not exceed the specified angular
limit.
ŸCheck that the pump-motor
alignment is correct, resting one
square object straight (ruler) at 90°
intervals. Check the clearance with
a feeler gauge.
ŸProceed to tighten the anchor and
check alignment and clearance
again; if necessary, repeat the
process from the beginning until
you get a proper alignment.
ŸInsert the joint by the clearance
between the hubs and rest it on
any of the covers. Lubricate the
slots and clearance with as much
grease as possible.
ŸFill the spaces between the grid
and around it with grease. Remove
excess.
ŸOil the seals to slide on the hubs,
align and assemble the covers,

segments are radial. To extend as
little as possible, go partially
inserting segments using a soft
mallet. Once the segments are in
position, push them to the bottom
of the grids.

NOTE 1: “X” is the difference between the measures of the clearance, taken at opposite
ends of the hub flanges.
NOTE 2: the values of the parallel offset may be absorbed by the articulation between
the hubs and the grid. In any case, the lifetime of the couplings will increase with a
minimum maintenance if a precision alignment is performed.
