INSTALLATION, OPARATION AND MAINTENANCE PAGE 1

SAFETY SECTION 1 Before starting the operation, consult the operation manual supplied by the driving unit manufacturer.

Before trying to open or handle the pump, it is necessary to:

1. familiar with the content of this manual.

2. Turn the energy feed source off in order to assure that the pump remains inoperative.

3. Allow the pump to cool off, in case it is overheated.

4. Check the temperature before opening any cover, plate or connection.

5. Close the suction and discharge valves.

6. Bleed the pump slowly and carefully.

7. Drain the pump.

This pump is designed to accept most of the non-volatile and non- corrosive liquids containing specific solids.

CAUTION

Do not operate the pump with the valve closed in the pressure line for a long time. This can make the liquid vaporize and increase the pressure, and also may cause the pump explosion.

ATTENTION Never start the pump in the rotation direction opposite to the indicated in the equipment. This can make the shaft impeller loosen.

PUMPS E11/2 & E2


INSTALLATION SECTION 2 This section offers general recommendations and procedures required for inspection, positioning and placement of the pump and the piping.

Great part of the information concerns the installations with static elevation, where the pump is placed above the level of the liquid to be pumped.

In cases of installations with throttled suction, where the liquid feeds the pump under pressure, some characteristics, such as assembling, piping configuration and priming must be specifically designed for each situation. If the pressure provided by the pump regarding performance and safety is critical, make sure that the admission pressure is limited to 50% of the maximum operation pressure allowed, as indicated in the pump efficiency curve.

PRE-ASSEMBLING INSPECTION Before the installation, check if the parts have been damaged during the transport. Proceed as follows: Check if there are cracks, wrinkles, damaged threads or other visible

damage. Check if there are loose parts. If so, tighten them . Observe the rotation direction indicated in the pump. Check if the shaft

rotates in the correct direction as indicated.

CAUTION Start the pump only in the rotation direction indicated by the arrow located in the pumps bearing house; otherwise the impeller can loosen from the shaft and cause serious damage to the pump

Check the levels and lubricate it if necessary. If the pump or the driving unit has been stored for more than 12 months, some of the components or lubricants may have exceeded the storing period and must be inspected or replaced in order to ensure the pumps peak efficiency and performance.

PUMPS E11/2 & E2


PUMP POSITIONING

ATTENTION The assembling of the motor-pump assembly and its accessories may be seriously damaged if the cables and chains used to lift or move the assembly are improperly wound up around the equipment.

Assembling The unit leveling is essential for proper operation. The pump must be installed in an accessible site and the nearest as possible to the liquid to be pumped. Wedges may be used for the leveling and vibration elimination.

SUCTION AND DISCHARGE PIPING

Materials Either pipes or hoses can be used in the suction and discharge lines. However, the materials must be compatible with the liquid to be pumped. If a hose is used for the suction line, this should have a rigid and reinforced wall to avoid flattening (collapse). The use of junctions in the suction line is not recommended.

Line Configuration Keep the suction and discharge lines as straight as possible in order to minimize head losses due to attrition. Use as least elbows and junctions as possible and, if necessary, use the long radius type to minimize head loss.

Pipes / Pump Connection Before tightening a connection flange, provide a perfect alignment between the flange and the pump suction flange. Never pull a pipe to its place by tightening the flange bolts and/or couplings. The pipes next to the pump must have independent support in order to avoid tension over the pump. If hoses are used, they must be properly supported when full of liquid and under pressure.

PUMPS E11/2 & E2


SUCTION LINES

In order to avoid air pockets, which can affect the priming process, the suction lines must be as short and straight as possible. When the operation involves liquid elevation in the suction, the line must always have a rising inclination towards the pump suction flange. If there is a falling inclination at any point of the line, air pockets will be formed.

Connections The suction lines must have the same gauge of the pump suction flange. If reductions are used, they must be of the eccentric type, installed with the flat part up in order to avoid air pockets formation. Valves are not usually used in the suction line. If one is installed, it must have its rod in the horizontal position to avoid air pockets formation.

Suction Line Positioning The immersed length of the suction line is critical for the efficient functioning of the pump. The following graph shows the minimum recommendation of submergence x liquid velocity.

NOTE

The necessary submergence may be reduced by installing a widening at the end of the suction line. The larger the opening, the smaller will be the admission velocity. Calculate necessary submergence based on the widening of the opening, using the following formula:

Volumetric flow [m 3 / s] Area[m 2 ]

PUMPS E11/2 & E2


DISCHARGE LINES Siphoning Do not finish the discharge line in a level inferior to the level of the liquid being pumped, unless a siphon-breaking valve is installed in the line. Otherwise, a siphon action may happen, causing damage to the pump.

Valves If it is necessary the use of a gate valve in the discharge line, use a valve with equal diameter or bigger than the pipe diameter, in order to minimize the head loss by attrition. Never install a gate valve in the suction line. In case of discharge with increased discharge, the installation of a gate valve and a check valve is recommended to protect the pump against water hammer and to prevent reverse rotation when there is a stoppage.

By-pass Lines During the priming cycle, the suction line air must be released to the atmosphere through a by-pass line installed between the pump discharge side and the check valve.

ALIGNMENT In an assembly started by elastic coupling or V-belt, the assembly must be performed so that the shafts are aligned and parallel to each other. It is very important to check the alignment after the pump and piping assembling before start-up. The assembly alignment must be checked before start-up. Before checking it, make sure that the anchor bolts are tightened. The pump base and driving unit bolts must also be firmly tightened.

CAUTION

Before checking the alignment, disconnect the driving unit to ensure that it will remain inoperative during the process.

PUMPS E11/2 & E2


ATTENTION The alignment in one direction can alter the alignment in another. Check each procedure after the alignment alteration.

Start-up by Coupling When using couplings, the axles must be lined up in the plans horizontal and vertical. Most couplings require specific clearance between the driving shaft and the driven shaft. Consult the coupling manufacturer manual.

Picture 1 A Flexible Coupling Picture 1 B Rigid Coupling

The flexible couplings must be aligned. It can be performed by a feeler gauge (See Figure 1A). The rigid couplings must be aligned by using a blade feeler gauge in order to measure the distance between the two halves of the part. (See Figure 1B). Check the parallel adjustment by resting a straight edge on both halves of the coupling, on the top, bottom and side areas.

Start-up by Belt When the start-up is performed by belt, the pump and drive shafts must be parallel, the pulleys aligned to each other, and the belts appropriately stretched. When the system uses two belts, make sure all of them are equal. The use of different belts will cause accelerated wear.

CAUTION Never start the pump if the protections are not placed on the rotating parts. The exposed rotating parts may contact clothes, fingers or tools and cause serious injury to people.

OPERATION SECTION 3

ATTENTION Do not use the pump for volatile, corrosive and inflammable liquids, or others the pump was not designed for.

The pump rotation and working conditions must be within the efficiency range.

PRIMING

Install the pump and piping as described in INSTALLATION Section 2. Make sure the piping is safely assembled. Check if the pump is properly lubricated. This pump is self-priming but it should never be started unless there is liquid inside it.

Add liquid inside the pump when: 1. It is being started for the first time. 2. It has not been used for a considerably long time.

PUMPS E11/2 & E2


3. The liquid inside the pump has evaporated. Once the pump has been filled up, it will prime as many times as necessary.

CAUTION

After the pump is full, place and tighten the filler cap properly. Do not start it unless the whole piping is firmly assembled. Otherwise, the liquid forced under pressure may cause injury to people.

In order to fill up the pump, remove the filler cap in the upper end of the pump and add clean liquid until it is completely full. Place the cover or the plug back.

START-UP Consult the operation and functioning manual provided with the driving unit.

Rotation The correct direction of the pump rotation is indicated by an arrow in the pump bearing house. If the pump is started in the opposite direction, the impeller may loosen from the shaft and damage the equipment severely. If the pump is started by an electric motor, remove the V-belts or couplings, or separate the pump from the driving unit before checking the motor rotation direction. When the motor is operating, observe the shaft rotation direction. If the rotation direction is incorrect, check the motor manual in order to know how to invert the rotation.

OPERATION Lines with By-pass If the by-pass line is open, the air of the suction line will be unloaded in the reservoir during the priming cycle. The liquid, then, will keep on circulating through the by-pass line while the pump is operating.

PUMPS E11/2 & E2


Lines without By-pass Open all the valves of the discharge line and start the pump. The priming is indicated by positive reading in the manometer of the discharge line or by a more silent operation. The pump may not prime immediately because the line must be previously filled up. If the pump does not finish the priming within 5 (five) minutes, stop the operation and check if there is any air admission in the suction line.

Leakage There must be no leakage in the pump junctions or connections. For this purpose you should maintain the connections well tightened to obtain the pumps peak efficiency and performance.

Liquid Temperature and Overheating The maximum liquid temperature for this pump is 80C (176 F). Do not operate with temperatures higher than that. Overheating may occur if the suction line or discharge valves are closed. The pump operation with closed valves may cause the liquid to boil, increase the internal pressure of the pump and rip up or even explode the pump volute case. In case of overheating, stop the pump and let it cool off before handling it. Fill the pump up again with cold liquid.

CAUTION

Do not remove plates, covers, indication instruments, plugs or connections from an overheated pump. The vapor pressure inside the pump may strongly eject the loose parts. Allow the pump to cool off before handling it again.

STOPPAGE Never interrupt the liquid volumetric flow suddenly. If the pumped liquid stops suddenly, water hammer may be transmitted to the pump and to the piping, damaging the equipment. Always close all the valves slowly. If the pump is started by internal combustion motor, reduce the rotation slowly and allow the motor to idle before stopping. If the application demands a very high discharge, close the gate valve gradually before stopping the pump.

PUMPS E11/2 & E2


BEARING TEMPERATURE VERIFICATION

Temperatures up to 70C are considered normal for bearings. They can operate safely up to 80C. The bearing temperature can be measured by placing a proper thermometer. It is recommended to keep this value for future verifications. A sudden increase of the bearing operation temperature indicates that they are close to the breaking point. Make sure that the bearings lubrication complies with the recommendations. The bearing overheating may also be caused by the shaft misalignment and excessive vibration. At first, new bearings may present higher temperatures than normal. Therefore, after some time of continuous operation, the temperature should achieve the normal level.

PROBLEMS AND SOLUTIONS SECTION 4

ATTENTION Before trying to open or repair the pump:

1. Be familiar with this Manual. 2. Turn the driving unit off in order to be sure that the pump will remain inoperative. 3. Allow the pump to cool off in case of overheating.

4. Check the temperature before opening the plates, covers or plugs.

5. Close the suction and discharge valves. 6. Allow the release of gas from the pump. 7. Drain the pump.

PUMP AND MECHANICAL SEAL DISASSEMBLING AND ASSEMBLING

Several maintenance functions can be carried out by means of the pump drainage and removal of the front manhole assembly. If a major repair is necessary, the piping and the driving unit must be disconnected from the pump. The following information will explain the complete disassembling. Before initiating the pump maintenance, disconnect the driving unit, making sure that the pump remains inoperative. Close all the suction line valves and discharge valves. For the driving unit disassembling and repair, consult our sales representative.

ATTENTION Before initiating the pump disassembling and maintenance: 1. Be familiar with the content of this manual. 2. Turn the drive off in order to assure that the pump

remains inoperative. 3. Allow the pump to cool off, in case it is

overheated. 4. Check the pump temperature before opening any cover,

plate or connection. 5. Close the suction and discharge valves. 6. Close the suction and discharge valves. 7. Drain the pump.

Front Manhole and Wear Plate Removal

Remove the volute case plug and drain the pump. Loosen the tightening tee, remove the fixation clamp and pull the front

manhole assembly and the volute case wear plate. Inspect the wear plate and replace it, if necessary. Inspect the Oring of the front manhole. Clean and reinstall the plug.

PUMPS E11/2 & E2


Flap Removal E 1. Pump: Remove the nuts and pull the suction flange together with the flap,

inspect the rubber flap and its counterweights. E 2 Pump:

Remove the flap pin. Reach the Flap through the front manhole opening and pull the complete

assembly. Rotating Assembly Removal

Remove the nuts and separate the volute case from the seal volute case and from the bearing house volute case. Remove the volute case joint.

Before removing the impeller, remove the seal grease fitting. Remove the plug from the seal volute case and drain out the oil to avoid its

leakage when the impeller is removed. Clean and place again the plug. Remove the impeller, unscrewing the impeller by using a soft rubber

hammer or a wood block counter-clockwise (seen from the impellers side). Caution: do not damage the impeller vanes

Inspect the impeller and replace it if it is cracked or worn Mechanical Seal Removal Remove the sleeve and the rotating part of the mechanical seal, sliding

the sleeve towards the shaft end. Use two hard wires with turned ends to remove the stationary parts from

the seal. Remove the Oring from the sleeve.

Shaft and Bearing Removal and Disassembling

NOTE Only disassemble the shafts and the bearings if there is any evidence of wear or failure. The disassembling of shaft and bearings in the field is not

PUMPS E11/2 & E2


recommended. It must be performed by qualified people in a place with proper tools. Keep the bearings out of dirt or foreign materials. Do not rotate the bearings dry, otherwise it may cause premature fault. Remove the drain plug from bearing volute cases and drain the lubricant

(E2 only); Remove the bearing cover and the retainer; Remove the joint of the bearing house and force the retainer off the cover; Place a wood block on the shaft end next to the impeller and hit it using a

hammer to remove shaft assembly and bearings from the bearing house; Clean and check the bearings while assembled; Clean the bearing house, shaft and components (except bearings)

using cleaning solvent in a soft soaked cloth; Check all the parts to detect excessive wear or failure and replace

them if necessary; Clean the bearings completely using new cleaning solvent, dry them with

compressed and filtered air and cover them with thin oil; Rotate the bearings by hand to check for jolts and or if they are stuck; then

check the balls; If it is necessary to replace the bearings, use an extractor to remove

them from the shaft; Push internal oil retainer and release it from the bearing house.

Shaft and Bearing Assembling and Installation Clean the bearing house, shaft and components (except bearings)

using cleaning solvent in a soft soaked cloth; Check all the parts to detect excessive wear or failure and replace

them if necessary; Check the shaft to detect distortion, spots or scratches in the thread

next to the impeller, repair the small faults by using a fine file or water sandpaper;

Replace shaft if it is defective; Place the retainer next to the impeller in the cavity of the bearing

house; Press the retainer to the inside of the volute case until the face is totally

parallel.

PUMPS E11/2 & E2


ATTENTION When assembling bearings on the shaft, never press or hit the cover on the balls or on the bearing cage. Press only the hub.

Bearings can be heated to facilitate the assembling. An induction

heater, hot oil bath or electric oven can be used to heat the bearings (never heat on a flame or on a hot metal sheet);

Heat bearings at uniform temperature, not higher than 120C; Assemble the bearings sliding them over the shaft, one at a time, until

they rest on each other totally (it must be done quickly, with continuous movement in order to avoid the cooling of bearings and to avoid them becoming glued to the shaft);

After installed and cooled, check if there were no bearing movements during cooling, that could have separated them from the prop;

In case of movement, compress the bearings against the prop, wearing properly-sized pair of gloves;

If the heating process is not available, wear appropriate gloves and mechanical or hydraulic press in order to assemble the bearings on the shaft;

Attach the bearing to the operation side with the retention ring; Introduce the shaft with the bearings assembled into the volute case until

the bearing on the impeller side rests on the bearing house prop; Press external retainer against bearing cover; Assemble the joint of the bearing cover and the bearing cover; Lubricate the bearing house.

Mechanical seal assembling

NOTE A new seal must be installed every time the seal is removed from the pump. Wear marks of the polished parts do not coincide during the second assembling. Reutilization of the seal can cause premature faults. Clean the mechanical seal cavity and shaft using new cleaning solvent in a

soft soaked cloth; Check the cavity of the stationary back-up ring, searching for dirt; the

cavity of the stationary seat must be completely cleaned before seal

PUMPS E11/2 & E2


installation; Lubricate the Oring of the sleeve of the shaft (E2 pump) and the Oring

of the stationary seat using a small amount of thin oil; In case the mechanical seal volute case has been removed, install the

joint of the volute case; Attach the shaft to the bearing house and attach the bearing house

cover using fixation bolts; In order to avoid damage to the Oring of the sleeve in the shaft thread (E2

pump), stretch the Oring on to a piece of pipe, install the pipe on the shaft thread and roll the Oring on the pipe towards the shaft.

Remove the pipe and keep on rolling the Oring through the shaft until it touches the shaft salience.

When installing a new mechanical seal assembly: Remove the protective covering between the seal faces; Lubricate the Oring of the stationary seat using thin oil; Install stationary element of the seal in the stationary seat and press the

stationary assembly against the cavity of the volute case until it rests on the cavity bottom completely (a plastic pipe can facilitate this operation);

Slide the seal rotating part (comprising sleeve of the shaft, spring and the rotating element) over the shaft until the seal faces touch each other;

Proceed with the assembling as described in the Impeller installation item;

Place the seal grease fitting back and after the impeller is assembled, lubricate as indicated in Lubrication item.

Impeller Installation Check the impeller and replace it if it is cracked or excessively worn.

Observe if there is any dirt or damage on the impeller and shaft threads. Clean and lubricate it if necessary.

ATTENTION

The shaft and impeller thread must be completely cleaned before impellers installation. The minutest particle of dirt on the threads may cause knocking of the impeller in the shaft, making a future disassembling difficult or even impossible without damaging the impeller or the shaft.

PUMPS E11/2 & E2


Rotation Assembly Installation NOTE

In case the pump has been completely disassembled, it is important that the manhole be installed at this moment to adjust the impeller clearance. In the E2 model, not only the manhole, but also the flap valve, because this is installed through the manhole opening. Attach the rotating assembly on the pump volute case with the fixation

bolts, do not tighten completely the fixation bolts until the front manhole is totally assembled and the impeller face clearance has been totally adjusted;

A clearance of 0.2 to 0.4 mm between the impeller and the wear plate is recommended in order to reach the pump peak efficiency and performance;

After the impeller rests on the wear plate, regulate the assembly by using the regulating bolts.

E2 Model Flap Assembling Reach by hand the flap valve assembling location through the opening of

the manhole and position the valve adapter in the assembling seat in the suction flange.

Align the adapter with the flange opening and attach the assembly using the check valve pin.

In case the suction flange has been removed, install the joint, use joint seal and attach it to the pump volute case using the bolts.

E 1. Model Flap Assembling The installation is simple, since the flap valve is assembled together with the suction flange. Just check if the flap and the counterweight are not damaged. If so, replace and assemble them together with the suction flange, attaching it in the volute case using bolts.

Front Manhole Installation In case the wear plate has been removed and replaced, center it carefully

on the manhole and attach it by using bolts and a pressure washer (the

PUMPS E11/2 & E2


wear plate must be concentric to avoid knocking when the front manhole is assembled).

Replace the Oring and lubricate it using a generous amount of number 2 grease;

Remove scales and particles from the surface, which may interfere or avoid a good sealing when in contact with the pump volute case.

NOTE

To facilitate a future disassembling, use grease or penetrating oil film on the manhole salience or any other surfaces that can contact the pump volute case. This will avoid rust and scales. Attach the front manhole assembly using the fixation clamp and the

tightening tee. Make sure that the wear plate does not fasten in the volute case.

Final Assembling of the Pump Install the key in the shaft and connect it to the driving unit; Make sure that the protections are installed on the rotating parts; Install the suction and discharge pipes and open all the valves; Make sure that all the pipe connections are correctly tightened, supported

and safe; Make sure the pump and driving unit have been properly lubricated; Remove the filler cap and fill the pump volute case with clean liquid; Reinstall the filler cap and tight it up.

LUBRICATION

Mechanical Seal Before starting the pump, remove the seal grease fitting cap and fill the mechanical seal Check regularly the oil level and keep the grease fitting always full..

Bearings In the E2 model check the oil level regularly by means of the display, keeping the level in the middle of the display. If necessary, add SAE 30 oil,

Under normal conditions, drain the bearing volute case once a year and fill it with clean oil. In case the pump is operating continuously or if it is in a place subject to fast changes in temperature, the oil must be replaced more frequently.

NOTE

Check the lubricant condition regularly in order to detect possible rust or condensation. This is especially important where there are large variations in temperature. When operating under low temperatures, refer to the oil supplier for the proper type of oil.

In the E 1 model the bearing house is already lubricated in the factory. Under normal conditions add lithium-based grease using the two bearing houses greasers every 250 hours of operation or once a month, whatever completes first. Under normal conditions, change likewise the grease every 5,000 working hours or every 12 months, whatever completes first. In case the pump is operating continuously or if it is in a place subject to fast changes in temperature, the grease must be replaced more frequently. When operating under low temperatures, refer to the lubricant supplier for the proper type of grease.
