Recommendations & Warnings
4Receiving 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.
4Storage
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.
4Service Stations
To find the nearest Barmesa Pumps
authorized service shop, please
directly contact your distributor or
the factory.
**See friction table in pipes and fittings
to determine the dimensions of the
suction and discharge. (Page 7)
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.
4Installation
(See Figure 1 for better reference). 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.
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 1/2" to 1" greater as that
of the suction volute or body.
A strainer or sieve should be installed
in the suction to prevent the entry of
objects. The strainer must have a free
entry area at least three times the
pipe diameter. Usually a suction valve
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.
4Suction
The anchors of the motor are to be
anchor, on a raised base,
approximately 4", this to prevent
accumulated water from entering the
motor.
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.

Installation
Suction height - Suction pipe should
have a slope of 0.39" per 3.3 ft of
suction. Never exceed 16.4 ft suction,
considering friction. (Figure 3)
Positive/Drowned Suction - A gate
valve is installed in the suction pipe
to service the pump (Figure 4). Volute
or body have plugs, and these must
be removed to allow trapped air to
escape.
Use pipe or hose reinforced
sufficiently robust to prevent
destruction due to high pressure.
4Discharge pipe
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.

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.
Install the foot valve at the suction
pipe and fill with liquid the superior
part of the pump's body. 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.
4Pre-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.

IMPORTANT! - When the
pump starts and once the
rotation has been verified,
if it detects under water
flow or pressure it will be
necessary to calibrate the
space between the impeller
and its pump housing.
When you start your equipment for
the first time, check that the valve in
the discharge is 90% closed. Open
the valve gradually until the engine
works at full load (plate amperage).
Never allow the amperage consumed
by the pump to exceed the maximum
allowed by the motor.
4Mechanical seal
The mechanical seals installed in the
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, consult your
BARMESA distributor for more
information.
Operation & Maintenance
Perform this step by removing spacer
shims that are installed between the
housing and the coupling. The shims
work to maintain the required
nominal spacing of 0.015" to 0.020"
between the impeller and the inner
wall of the housing due to the natural
wear and tear that occurs. The pump
has 4 factory installed spacer shims
and four more parts. The 0.005" shim
is transparent and without a
perforation mark, the 0.010" shims
has a perforation mark, the 0.015"
shims has two perforation marks and
the 0.020" shims has three
perforation marks. If necessary, start
by removing the 20 and 15
thousandth shims and check if the
flow and pressure of your pump is as
desired.
IMPORTANT! - Always
disconnect the pump before
applying maintenance,
service or repair to avoid
electric shock.
4Maintenance
If the mechanical seal does not leak
and there is a need to open the
pump for inspection or cleaning, DO
NOT remove the seal, only remove
the spring if the impeller had to be
removed. Once a seal has been in
operation it is very difficult that when
removing and reassembling it does
not show leaks.
4Disassembly
Drain and rinse the system. Remove
the 4 screws from the case and
remove the case. Check the
conditions of the shims and replace
them if necessary. Remove the
impeller; the impeller compresses the
spring of the mechanical seal and is
prepared for the impeller to jump off
the shaft when unscrewed; to
remove it, you must turn it
counterclockwise while holding the
shaft with a screwdriver at the rear of
the engine. Remove the rotating part
of the mechanical seal by sliding it
through the sleeve, be careful with
the faces of the mechanical seal as it
is fragile when handling. Remove the
screws that secure the seal plate to
the adapter and the screws that hold
the coupling to the motor.
IMPORTANT! - Handle seal
parts with extreme care.
DO NOT DAMAGE polished
surfaces.
4Reassembly
Assemble the adapter assembly, seal
plate, sleeve, mechanical seal and
housing in reverse order of
disassembly. Always check that O-
ring gaskets are in good condition, or
if necessary, replace them.
The adapter must be screwed to the
motor with the identification plate
facing up, then screw the seal plate to
the adapter, replace the sleeve,
applying liquid screw fastener on the
end that goes to the motor and
sliding it along the arrow. Verify that
the faces of the mechanical seal do
not show cracks or bumps, that if so,
you will need to replace it. Position it
carefully by sliding it through the
sleeve, place the spring on the
mechanical seal and screw the
impeller clockwise. Screw the casing
and pump base.
IMPORTANT! - All parts
must be clean before
reassembly.

Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Troubleshooting Chart
PROBLEM PROBABLE CAUSE CHECK
- Threaded joints in the suction tightness.
- Gaskets for no wear.
- The mechanical seal for leaks.
- The drain plug has leaks.
- The vacuum gauge may be leaking.
2. Insufficient liquid in the
pump casing. - That the pump's body is filled with water.
3. Low operating speed. - The motor speed (RPM).
- Impeller rotates freely.
- Internal parts are clean.
5. Mechanical defect. - That the internal parts are not worn.
B) The pump does not prime,
the vacuum gauge reading
indicates higher than normal.
1. Pipe clogged suction. - The suction line is clean.
1. The pump speed is very
low. - The voltage is correct.
2. Mechanical defects. - The internal parts for wear.
- The discharge is clear of obstructions.
- That the discharge valves operate correctly.
1. suction dynamic level
too high.
- When the pump is operating, never lacks
water in the suction.
- For leaks in suction piping, flanges and
gaskets.
- That there is no vortex effect at the end of
the suction, this lack of water.
- That screws are tight at the base.
- There are no cracks in the base.
- The dynamic level is not too high
- That the pumping capacity is not too much.
- The pump is operating in the range of NPSHR
- If reducing flow makes the noise gone, then
the problem is in the point above; partially
close the discharge valve.
- The bearings for wear.
- That there is oil in the deposit.
- The impeller does not have any foreign
material.
- The pump is operating in the range.
- That the alignment is correct.
1. Low voltage. - The voltage is correct.
- The amperage of the plate is not exceeded.
- There is no foreign material that may force
the impeller.
- That the motor is suitable for the pump.
2. Overload.
A) The pump does not prime,
the vacuum gauge indicates a
lower reading than normal.
F) The pump priming pumps
well and satisfactorily but noisy.
E) The pump loses its priming
during operation, vacuum
gauge reading drops to zero.
G) Motor overload.
4. Vibration.
1. Pump base is loose.
2. Cavitation.
3. Bearings.
2. The pump is sucking air.
D) The pump priming good
vacuum gauge reading is
almost normal, reading the
manometer is greater.
1. Discharge obstructed.
1. Air leak in the suction
system.
4. Bound pump.
C) The pump priming good
vacuum gauge reading is
normal, the manometer
indicates a lower pressure than
normal.
