» Pump reception
Upon receving ofthe pump; itisimportant to verify that there is no missing parts/components and has not suffered anydamage.
Any claim for shortage or management should be directed to the transportation company. This pump is rigid and heavy lifting equipment must be able to adequately support the entire asembly.
Lift pump using a suitable sling (see figures 2 and 3) are examples or proper lifting ofthese pumps.

» Pump instalation
All pumping equipment should be installed as close as possible to the source of liquid being pumped, in addition to a base that is able to absorb vibrations generated during the operation of the pump, this facility should de located in a space so that the work of operation, maintenance and repair can be performed properly and without risk of equipment damage orpersonalinjury.
» Base plate foundation and leveling
Foundation: a good foundation is made by pouring concretein the location area of the base plate, the type of anchor is usually sleeve type, since this allows a movement of the basis for the final adjustment. In Fig. 4 and 5 two types of anchoringare shown:

Recommendations & Warnings

Leveling: (seefigure6and7) a) Shall have two sets of shims on the sides of each anchor to reach a height of 12″ above the work floor level, and allow the appropriate application of pouring concrete, plus a uniform settle in the base plate, once the concreteis emptied. b) If you use anchor sleeve, remove the waste solids or liquids of the interior of each anchor sleeve andinsert paper or rag to prevent them from filling with concrete when pouring. ) Carefully install the base plate, ensuring that all anchors fit together into their respective holes, and sit on the shims evenly. d) Level the base with a tolerance of 1/8″ (3.17 mm ) length and 1/16″ (1.58 mm) width, adjusting shims. e) Install nuts, tightening them by hand. Once aligned the motherboard, the next stepisthe pump.

» Alignment procedure
Initial alignment: this is done before putting into operation the pump and is divided into three stages: .

• Before pouring the concrete: To ensure base plate alignment, seen in the leveling section, subsections C andD. .
• After pouring the concrete: in order to ensure that there are no sudden movements or abnormal contractions of concrete during casting. .
• After connecting the pipes: checking that the stress on the pipeline have not altered the alignment, if any misalignment, modify the suction and discharge support system to reduce the stress in the flange of the pump.

Final alignment: after the first pump operation the alignment should be checked to ensure that everything is in order, starting from this, you should check the alignment periodically, to maximize the pump performance. A unitis in proper alignment when the angular and parallel alignment readings do not exceed 0.002″ (0.05 mm). Here we present some criteria and suggestions for achieving a proper alignment.
Angular alignment.
Vertical: Consists of installing a dial indicator (see Figure 8) in the top half of the coupling “X” leaving it fixed, then coupling “Y” is halfway rotated. If reading exceed 0.002″ (0.05 mm ), this means that the motor is offset from the top down, install shims at the motor feet to correct thereadings.

Horizontal: Consist of installing a dial indicator (see Figure 9) in the top half of the coupling “X” leaving it fixed, then coupling “Y” is halfway rotated. If the readings exceed 0.002″ (0.05 mm), this means that the motor is offset from the top down, install shims at the motor feet tocorrect the readings.

Parallel alignment.
Vertical: Consist of installing a dial indicator (see Figure 10) in the top half of the coupling “X” leaving it fixed, and four cardinal points in the half of the “Y” coupling are inspected. If readings exceed 0.002″ (0.05mm), means that the motor is offsetfromthe top down, install orremove equal amounts of shims at the motor feet, tocorrect the readings.

Horizontal: Consist of installing a dial indicator (see Figure 11) in the top half of the coupling “X’, leaving it fixed, and then proceeds to inspect the four cardinal points of the “Y” coupling. If readings exceed 0.002″ (0.05 mm), means that the motor is offset from the top down, so install or remove equal amounts of shims atthe motorfeet, to correct the readings.

» Concrete pouring application

1. .Build a dam with particular area and height for concrete pouring (see Figure 12).
2. Clean the areas that have direct contact with the concrete pouring with a damp cloth, wet thorougly.
3. It is recommended that pouring be consistent (see distributor instructions).
4. Pour the concrete in order to reach the dam level, then make sure there are no trapped airbubbles.
5. Letfirstpourhardenfor 18 hours.
6. Make the second concrete pouring filling the whole base plate (see Figure 13).
7. Letharden the second concrete pouring atleast48hours.
8. Tighten nuts anchoring the base plate.
9. Verify pumpalignment.

» General piping

1. Clean all pump piping, valves and accessories beforeassemble.
2. The pipe must be connected to the pump until concrete pouring has completely hardened.
3. The lengths of pipe should be as short as possible in order to minimize friction losses.
4. Where hazardous liquids are handled, piping should allow pump to be washed before disassembling the unit.
5. All piping must be supported independently apart from the pump, this support should be adequate to prevent misalignment of the pump.
6. All the suction pipe must remain adequately submerged below the liquid level avoiding vortex and air pockets in thesuction.

Suction pipe
a) The suction pipe diameter should never be less than the suction flange of the pump, pipe diameter is recommended to be one or two times the suction flange diameter.
b) In addition, use an eccentric reducer withslopingside down.
c)Avoidinstalling short radius elbows.
d) At least there should be a straight equivalent of 2 or 3 long pipe diameters from the suction flange to the first side section.
e) When simultaneously having 2 pumps systems working on the same supply the suction pipe must be separated as much aspossible.
f) When the suction is negative, i.e. when the pump is above the suction level (see  Figure 18) all joints must be airtight,suction piping must be without air bags, thisrequiresinstallingafoot valve.
g) When the suction is positive, i.e. when the pump is with suction flooded, (see Figure 17) a gate valve should be installed inthesuctionlineat leasttwo diameters of the suction flange, no portion of the piping should extend below the suction flange.
Discharge pipe
a) The discharge must have gate valves and check valves, install the retention valve between the pump and the gate valve, this will permit inspection of the check valve, gate valve is required for the priming, flow regulation, inspection and pump maintenance.
b) If a reduction bell is used as a booster, it should be placed between the pump and thevalve.
c) Damping devices shall be used to protect pressure pulsations and water hammer.
Final verification
Turn the shaft by hand several times ensure that the parts are friction free, besides verifying alignmentinaccordance with section “Finalalignment”.
» Pump start up preparation
CAUTION! – Block the motor power supply before perfor- ming any maintenance, operation and repair or adjustment of the pump. (To prevent accidental starting and/or personalinjury).

» Pump rotation verification

1. Make sure the coupling is securely fastenedtothe shaft.
2. Verify that nobody can interfere with this operation.
3. Tum on and off the motor quickly to verify the direction of rotation, rotation should correspond with the shaft on the bearing box. You may cause severe damage if the pump runs in the wrong direction.
4. Block the motor power to proceed with thestart up preparation.

» Impeller clearance verification
Before operating or starting the pump you should verify the impeller. The efficiency of the pump maintains when having a properimpeller clearance.
The best way is obtained by fixing the clear frontimpeller in the factory, with the default limits that may be compatible with the service conditions. The minimum values for impeller adjustment are illustrated in the
“Impellers Clearance at Operating Temperatures” table, where you can find values for different temperatures, depending on themodel, these values are necessary to prevent the driver to touch thesurface of the body due todilatation of metal being a result of the pump operation, not being within these ranges may cause significant damage to the unit.

» Bearings lubrication
Oil lubrication : Fill the bearing oil by removing the oil filler cap located on top the box until the oil sight glass indicates half, use a high quality oil turbine type with rust and oxidation inhibitors. (See table: “Minimum Requirement for oil lubrication”).
Grease: Pumps are shipped grease free. (See Table “Minimum Requirements for grease lubrication”).
Bearings greased for life: These bearings are filled with grease and sealed by the manufacturer. If the pump is operated after a long idle time, flush the bearings and bearing frame with a light oil to remove contaminants. During washing, slowly tum the shaft by hand. Finally, flush the bearing boxwith properlubricating oil toensure oil quality after cleaning.

» Shaft seal
Mechanical seal: the pumps can be sent with or without mechanical seal installed at the factory, the common mechanical seal for BARMESA 911 series pump is the cartridge type; these are prefabricated at the factory and do not require field adjustment, for other types of mechanical seal see the installation instructions and manufacturer setting.
Packing gland: these pumps are shipped without packing rings, lantern rings, gaskets, etc., these are available as accessories and must be installed before starting the pump.
» Packing installation

1. Perfectly clean seal plate cavity.
2. Must twist packing and lantern rings, just to keep in touch with the sleeve, (see in Figures 14 and 15 the correct way to turntheseringsis shown).
3. Insert packing, this should be done alternating the joints of each packing and following the sleeve contour.
4. The arrangement of the packaging should be packing rings at the bottom of the chamber, a lantern ring intermediate and three packing rings at the end, then install the gland (see Figure 16, for example).
5. Install the gland by placing the two halves, with studs and install the nuts (handtightened).

» Priming the pump
Never start the pump until it has been properly primed. You can use different priming methods depending of the type serviceand installation required. Providing suctions above the pump:

1. Slowly open the gate valve located in thesuction pipe (see Figure 17).
2. Open the vents in the suction and discharge pipe until water flows.
3. Closeventvalves.

Providing suctions below the pump:
An aspiration valve and external liquid can be used in order to prime the pump, as shown in Figure 18 and 19. The external liquid can be obtained from a priming pump, a depressurized discharge pipe or anexternalsupply.

1. Close the discharge valve and open the volutevents.
2. Open external supplier valve just enought to have water escape the ventilation valves.
3. Close vent valves first and the external supplier line.

» Pump operation

1. Make surethe suctionvalve and another recirculation or cooling valves are open.
2. Totally close or partially open the discharge valve, following the system conditions.
3. Start the motor. It is important to observe the manometer. In case the discharge pressure is not reached, stop theengine, prime the pump asecond time andstartagain.
4. Slowly open the discharge valve until thedesire flowis obtained.
5. Always operate this pump at or near the flow regime, to prevent damage resulting from cavitations or recirculating conditions.
6. Motor can be overload if the specific gravity (density) of the liquid being pumped is greater than the original stated liquid or if the maximum flow is exceeded. (See table: inimum Recommended Flow”forBarmesa 911 series pumps)

Operating pumps at reduced capacity: do not operate below the mi um flow requirement or with the discharge/suction valves closed. In this condition there is a risk of an explosion due to the pumping vaporization which may lead to pump a failure or a personal injury.
Operating pumps at freezing conditions: exposure to freezing conditons while the pump is out of service can cause the liquid to freeze and damage the pump. Liquid should be drained from the pump.
Damages occurring mainly for the following reasons:

1. High radial thrusts (shaft or bearing stresses).
2. High levels of vibration. (Affect bearings, mechanical seal, packing gland).
3. Heat generation. (Vaporization causes inner components to rotate, jam or scratch).
4. Cavitations. (These causes damage within the pump, especially with the pumpsimpeller).

» Final alignment

1. Start the unit in real operating conditions enough time in order to bring the pump and engine into their operation temperature.
2. Verifyaligmentwhile the unitis stillhot.
3. Reinstall the coupling guard. L. . » Routine inspection + Periodically inspect the pump and pipelines, making sure there are no leakage.
   • Verify unusual sounds, vibrations or temperature onthe bearings.
   • Bearings constantly and periodically lubricated.
   • Sealinspection (noleakage).
   • Verifydischargeandsuction.
   • Vibrationsanalysis.
   •  Temperature verification.
   • Verifyoil levels on bearings box.
   • Packaging (any excessive leak requires  adjustments or a possible replacement).

» Bimonthly inspection

• Foundation, anchor and hardware inspection verifying everything is well adjust.
• Oil change, every two months (1850 hours) or before, depending on conditions where oil can be contaminated or decompose.
• If the unit was idle, the packaging should be inspected and if needed replaced.
  Bearing periodically inspected and lubricated.

» Yearly inspection
Verify pump capacity, (pressure and power) if the pump efficiency doesn’t meet the needed requirements for the process, the pump should be disassembled, inspected and replaced any worn out pieces. In case this  !nspec_tlon results are OK, a system inspection should be done.
» Oil lubricated bearings
To fill the bearing box with oil, first oil cap located on top of the bearing is removed, add oil until the oil sight glass mark is located at the center, then install the oil cap.

» Grease lubricated bearings

1. Clean and wipe outall elements such as: the grease container, relief plugs, etc. to prevent dirt from entering the bearing support.
2. Fill both grease cavities through the greased ducts until fresh grease comes out the reliefholes.
3. Reinstall relief plugsin place.

» Gaskets
The area used for gaskets and packing glands is not always filled at the factory and must be filled before operating the pump, it can be provided in a box of accesories with the pump. Before installation make sure the gland is clean, checkthe sleeve for scratches or wear, if so replace if necessary. Begin by placing two packing rings, then the lantern ring, three packing, rings, finally adapt the gland (see figure 22).To place the packing and latern rings you must make a twist motion type, as shown in figure 14 and 15 lternating
90° and tightening each ring to ensure proper compression ofthe gland.
The gland should be tightened evenly to achieve a good seal, excessive tightening ofthe gland can cause premature wear on the packaging and/or sleeve. Upon completion of this process, the shaft should be turned by hand once the pump is working afinal gland adjustment can be made.

» Mechanical seal
If a mechanical seal is required a manufacturer catalog must be provided withis respective data. This catalog orplan shall be kept for future repairs or mantenance. It must also specify the required type of washing liquid and coupling points, every detail of installation, lubrication, pipes must be checked before starting the equipment (seeFigure23).
Because the mechanical seal service life depends on many factors such as: lubrication, maintenance, liquid being handled, operating conditions, etc is not possible to determine the lifetime of the mechanical seal.

IMPORTANT! – Never JA operate the pump when fluid is not supplied to the mechanical seal, this can cause damage to the mechanical seal, wearing on sleeve, besides being able to cause serious injury if these sealsfail.

» Inspections of pump parts
Must inspect all parts of the pump before being reassembled, using the following criteria noted here to achieve a suitable pump operation.
During inspection if any piece or component does not have the minimum requierements it should be replaced. Impeller: (see Figure 26)

• You should inspect the impeller vanes checking if they are damaged, must be replaced if the slots are greater than 1/16″ deep or if they have a uniform wear over 1/32″ (point A).
• Inspect the rear vanes, if they have morewearthan 1/32″ (point B), replace theimpeller.
• Inspect the leading and trailing edges of the blades, if these presents corrosion or wear (point C), substitute foranewimpeller.

Volute:

• You should inspect the inside of the body and the gasket body surface, if you have slots than 1/8″ it should be repaired or replaced (see Figure 27).

Adapter:

• When inspecting the adapter, you should check for any cracks or excessive corrosion damage, must be replaced (see Figure 28).

Seal plate:

• When inspecting the seal plate should check the packaing chamber is cleaned and does not have excessive corrosion, in addition review the area of the flat place that makes direct contact with the volute’s inside should be replaced if you have any crack or
  more wear than1/8″ deep (see Figure 29).

Bearing support:

• Check the bearing seat according to the “Table for bearing adjustment and tolerances’, replace if values exceed thoselistedinthetable (see Figure 30).
• Inspectthe locksslot, it should not have any cracks, replace if necessary.

Shaft:

• Review the shaft, reviewing courts bearings, the setting must match the tolerances specifiedin the table: “Table for bearing adjustment and tolerances”.
• Inspect the righteousness of the shaft, replace the shaft it exceeds more than 0.002″ (0.050 mm) between centers.
• Inspect the shaft, reviewing the general aspects, replace if you have grooves or pits (see Figure 31).

Sleeve:

• When inspecting the sleeve, review the outer and inner tracks, replace if you have grooves or pits (see Figure 32).

Bearingbox and bearing boxsupport:

• Inspectthe bearingbox, make sureitis not cracked.
• Inspectthe innerbearing according to the “Bearing adjustment and tolerances table”
• Replaces if values exceed those listed inthistable.
• Check all lubrication passages and make sure they are not clogged (see Figure33).
• Ifthe bearing was exposed to the fluid pump, inspect for corrosion, replace if necessary.

Bearings:

• Check the bearings, the condition of these is important in determining working conditions within the bearing box, note the condition of the lubricant, this information may be useful in determining future prevention.
• If the wear cause is not normal, it must be corrected before installing new bearings.
• Donotreusethebearings.

Labyrinthseals:

• Check the status of the labyrinth seals, inspect so the gaskets have no cuts or cracks, replaceifnecessary.
