STORAGE

Goulds Water Technology carefully preserves and protects its products for shipment. However, the effective life of the preservatives applied at the factory can vary from 3 to 18 months depending on the severity of the environment in which the equipment is stored. This section provides procedures for preparation prior to storage and maintenance during storage of Goulds Water Technology DWT pumps. These procedures are necessary to protect the precision parts of the pumps. Specific procedures for storing motors, gearheads, and engines, should be obtained from the equipment manufacturer. This section is intended to be of general assistance to users of Goulds Water Technology DWT pumps. It shall not modify, amend and/or otherwise alter the scope of Goulds Water Technology DWT pumps warranty responsibilities to the purchaser in any way whatsoever.

Preferably, the storage area shall be paved, well drained and free from flooding, and be indoors whenever possible.

Weatherproof coverings used for outdoor storage shall be flame resistant type sheeting or tarpaulins. They shall be placed so as to provide good drainage and air circulation and shall be tied down to protect from wind damage.

Storage area shall be maintained in a clean condition at all times.

Pumps and/or component parts shall be placed on skids, pallets, or shoring to permit good air circulation.

Pumps and/or component parts shall be sorted so as to permit ready access for inspection and/or maintenance without excessive handling.

Pumps and/or component parts stacked during storage shall be arranged so that the racks, containers, or crates bear full weight without distortion of pumps or parts. Identification markings must be readily visible. Any cover removed for internal access shall be replaced immediately.

Pump and bowl assembly shafting shall be rotated counter clockwise, as a minimum, once a month. Shaft shall not be left in the same previous position, nor in the extreme raised or lowered lateral position. Shaft should rotate freely.

NOTE: For further information on these procedures,

contact your Goulds Water Technology representative.

Recommended Storage Procedures

Controlled storage facilities should be maintained at an

even temperature 10º F (6º C) or more above the dew point with relative humidity less than 50% and little or

no dust. (If these requirements can not be met the pump is to be considered in uncontrolled storage.)

For uncontrolled storage periods of 6 months or less, the pump is to be inspected periodically to insure that all preservatives are intact.

All pipe threads and flanged pipe covers are to be sealed with tape.

The pump must not be stored closer than six inches

(15 cm) from the ground.

Uncontrolled Long Term Storage Preparations

CAUTION

When applicable to the pump, storage periods over six months require the preceding storage procedure and storage preparation plus the following:

Inspect the lube oil piping and either fill the piping with rust preventative oil, or re-coat the piping periodically to prevent corrosion.

Bowl Assembly

The bowls are generally of flanged construction for accurate alignment and ease of assembly and disassembly. Impellers may be either open or enclosed depending on the design requirements. They are fastened to the pump

shaft by taperlocks. For temperatures over 140°F (60°C) and in the larger size bowls (over 18”), impellers are

keyed to the shaft.

Place 10 pounds (4.5 kg) of moisture absorbing desiccant or 5 pounds (2.3 kg) of vapor phase inhibitor crystals

near the center of the pump. If the pump is assembled,

place an additional one pound (0.5 kg) in the discharge

nozzle securely fastened to the discharge elbow.

Install a moisture indicator near the perimeter of the

pump. Cover the pump with 6 mil. (0.15 mm) minimum

thickness black polyethylene or equal and seal it with tape. Provide a small ventilation hole approximately

½ inch (12 mm) diameter.

Provide a roof or shed shelter to protect from direct exposure to the elements.

GENERAL DESCRIPTION

The model DWT pump is a vertical turbine lineshaft pump, which is designed to meet wide ranges of service with maximum dependability. See Figure 1 for open lineshaft pump and Figure 2 for enclosed lineshaft pump.

Drivers

Hollow shaft motors or right angle gear drives, are often used with a separate head shaft through the driver and connected to the pump by a threaded coupling.

Installation

WELL CONDITIONS

When the DWT pump is to be installed in a well, consideration must be given to the well before installation. Check the inside diameter of the well and the maximum outside diameter of the bowl and column assemblies to determine that there is adequate clearance to install the pump assembly in the well casing. Also insure that the well is deep enough to receive the full length of pump.

1. The DWT pump unit must be operated in a straight portion of the well.

Installing a unit in a crooked well may bind and distort the pump column with

potential resulting malfunction.

2. When the straightness of the well is not known,

the well should be “gauged” prior to installation

by lowering a dummy assembly, slightly longer and larger diameter than the bowl assembly. Gauging is also important when a stepped well casing is used, with the lower part of the well casing having small inside diameter.

Discharge Head

The discharge head is either a cast iron head or a fabricated Steel head. Ports are provided for connecting the pressure gauge, stuffing box bypass return and lubricator connections. The driver support portion of the discharge head is designed with large windows for easy stuffing box or tension plate adjustment. The windows are covered with coupling guards for safe operation.

Column

Threaded or flanged column construction provides positive shaft and bearing alignment. Bearings are spaced to provide vibration free operation below the shaft. This will insure long bearing life and reduced shaft wear. For open lineshaft, the shaft is supported within the column by using bearing retainers in the column assembly. For enclosed lineshaft, the bearings are also the tube couplings of the shaft-enclosing tube. The shaft-enclosing tube is stabilized in the column pipe by tube stabilizer.

3. The well should be developed with a test pump prior to installing the permanent pump. Test pumping the well serves several purposes. It removes the excess sand encountered during the initial pumping of the well. Pumping sand or other abrasives with a DWT pump will shorten the life of the pump and can void the warranty.

4. The test pumping also provides a means of determining the capacity and drawdown. The well capacity should equal or exceed the pump capacity. If the pump removes water at a higher rate than the well produces, the drawdown will be excessive and the pump will cavitate or ‘starve’ resulting in damage to the pump.

5. The pump must be equipped with enough column pipe to assure that the bowl assembly remains submerged during operation.

FOUNDATION AND PIPING

SUB BASE (SOLE PLATE) INSPECTION

Sub base and sole plate are terms in common use to describe a general class of solid steel plates mounted

in grout (or bolted to steel structures) at the pump-

foundation interface.

1. Remove the sub base from the pump discharge head, when shipped assembled.

2. Completely clean the underside of the sub base. It is sometimes necessary to coat the underside of the sub

base with an epoxy primer. (This is available as an option.)

3. Remove the rust preventative solution from the machined topside with an appropriate solution.

SITE WITH CONCRETE FOUNDATION

1. A pump should have adequate space for operation, maintenance and inspection.

2. Sub base mounted pumps are normally grouted on a concrete foundation, which has been poured on a solid footing. The foundation must be able to absorb any vibration and to form a permanent, rigid support for the pumping unit.

5. Carefully lower the sub base onto the foundation bolts. Hand tightens the nuts.

6. Leveling the sub base may be done by several methods. Two common methods are:

A. Using leveling the wedges. This is shown in Figure 4.

B. Leveling nuts on the anchor bolts.

Regardless of the method, a machinist level must be used for leveling.

NOTE: When using a machinist level, it is important

that the surface being leveled is free of all contaminants, such as dust, to ensure an accurate reading.

7. Level the sub base in two directions at 90 degrees on the machined surface. The levelness tolerance is 0.005 inches per foot for commercial, and 0.001 inches per foot for API.

SUB BASE GROUTING

1. Inspect foundation for dust, dirt, oil, chips, water, etc. and remove any contaminants. Do not use oilbased cleaners as grout will not bond to it. Refer to grout manufacturer’s instructions.

2. Build dam around foundation (See Figure 4).

Thoroughly wet foundation.

3. Pour grout between sub base and concrete foundation, up to level of dam. Remove air bubbles from grout as it is poured by puddling, using a vibrator, or pumping the grout into place. Nonshrink grout is recommended.

4. Allow grout to set at least 48 hours.

5. Tighten foundation bolts.

4. Remove water and/or debris from anchor bolt holes/ sleeves prior to grouting. If the sleeve type bolts are being used, fill the sleeves with packing or rags to prevent grout from entering.

PIPING

Guidelines for piping are given in the “Hydraulic Institute Standards”, available from: Hydraulic Institute,

9 Sylvan Way, Parsippany, NJ 07054-3802 and must be reviewed prior to pump installation.

Never draw piping into place by forcing

WARNING

CAUTION

the flange connections of the pump. Pipe strain will adversely effect the operation of the pump resulting in damaging the equipment and possible physical injury.

1. All piping must be supported independently and

line up naturally with the pump flange so that undue pipe strain is not imposed on the pump.

2. DO NOT connect piping to pump until grout has

hardened and pump hold-down bolts have been tightened.

3. It is suggested that expansion loops or joints, if

used, be properly installed in discharge line. When handling liquids at elevated temperatures expansion joints are used, so linear expansion of piping will not draw pumps out of alignment.

4. Carefully clean all pipe parts, valves and fittings,

and pump branches prior to assembly.

3. Place two I-beam supports across the base plate opening, strong enough to safely support the weight of the entire pump assembly. These I-beams should be connected by threaded rods and nuts so as to clamp them firmly together for the portion to be

supported. (See Figure 5).

5. Isolation and check valves should be installed in discharge line. Locate the check valve between isolation valve and pump, this will permit inspection of the check valve. The isolation valve is required for regulation of flow, and for inspection and maintenance of pump. The check valve prevents pump or seal damage due to reverse flow through the pump when the driver is turned off.

6. Increasers, if used, should be placed between pump and check valves.

7. Cushioning devices should be used to protect the pump from surges and water hammer if quickclosing valves are installed in the system.

INSTALLING THE BOWL ASSEMBLY

Do not work under a heavy suspended

object unless there is positive support and safe guards, which will protect personnel, should a hoist or sling fail.

Do not attempt to lift bowl assembly by the pump shaft. This can result in

damaging the pump shaft.

1. Prior to installing the bowl assembly, check that

all capscrews are tight. Turn the pump shaft by hand and make sure it turns freely. Remove all accumulated dust, oil or other foreign material from the external surfaces.

2. If pump setting exceeds 200 ft., measure the

available bowl assembly lateral (shaft end play) by

pushing shaft toward suction bowl, mark shaft, pull shaft out and mark again. Measure the distance between the marks and record. This will later aid in adjusting the final impeller position.

For pump setting over 200 ft. this measure must complete before proceeding.

Figure 6

4. Place a suitable hoist or derrick over base plate opening with the hook in the center.

5. If a suction strainer is provided, assemble it to

the suction bowl or to the end of suction pipe (if provided).

6. Install suction pipe, if provided. Place an elevator clamp just below the pipe threads. Attach a sling to the clamp and to hoist hook. Hoist over the well. Lower the suction pipe until clamp rests firmly on the supporting timbers.

7. Place the elevator clamps just below the discharge bowl. For flanged column install two threaded eyebolts through the discharge bowl bolt holes 180º apart for flanged column. For threaded discharge utilize a lifting bail sized to handle the weight of the bowl assembly and suction apparatus.

8. Attach a sling to the elevator clamps, eyebolts, or lifting bail and hoist it into position over the

foundation opening. (See Figure 6).

9. If suction pipe is provided, lower the bowl assembly until the bottom end of the suction bowl meets the top end of the suction pipe. Screw the bowl assembly onto the suction pipe.

10. Carefully lower bowl assembly, guiding the unit so it does not strike the sides of the opening. Continue to lower bowl assembly until the elevator clamps or discharge bowl flange rests firmly on the I-beam supports.

11. Place a cover over the discharge bowl opening to prevent entrance of dirt or other foreign matter until ready for installation of the column assembly.

Do not drop any foreign object into the

bowl assembly. Such an object can cause serious damage to the pump and any downstream components. Any foreign object dropped into the bowl assembly must be retrieved prior to continuing assembly.

INSTALLING THE COLUMN

CAUTION

OPEN LINESHAFT

Lineshafts are coupled with threaded or keyed couplings. Column pipe may be threaded or flanged. When provided, see the Certified Pump Outline Drawing for the number of column and shaft sections required. The top and bottom sections may be special lengths:

1. Check the lineshaft (646) for straightness. Average total runout should be less than 0.0005” TIR per foot, not to exceed 0.005” T.I.R. for every 10 feet

of shafting.

NOTE: Bottom section of column pipe should not be

longer than 5 feet.

2. Hoist the first piece of lineshaft over the bowl assembly. Lower the lineshaft until the bottom end is properly aligned with the coupling of the pump shaft. Apply a thin film of oil to the threads on the

lineshaft (646) and the coupling (649) (for nongalling material or Molykote if galling material).

Use “MOLYKOTE” Dow Corning or equal for all galling material such as

316 stainless steel.

3a. With lineshaft in the proper position on the

coupling, screw lineshaft into the coupling manually until resistance is felt. A fine wire inserted in the hole at the center of the coupling can be used as a gage to determine when the coupling is correctly positioned on the shaft. Remove the wire after installing the shaft. Completely tighten the joint by using a pair of pipe wrenches. Use care not to damage any bearing journal areas on the shaft.

NOTE: Shaft threads are left-handed.

Make up threaded joints manually to

verify that the threads are properly engaged prior to applying a wrench. If cross-threading occurs, break the joint and repair the threads. If the threads are beyond repair, replace the damaged part.

3b. With a keyed coupling insert

the key into the pump shaft. Lower the sleeve over the pump shaft, to approximately

1.0 in (25.4 mm) below the

top of the shaft. Then lower the lineshaft until it touches the pump shaft. Insert the split ring into the grooves of the pump shaft and lineshaft. Raise the sleeve until it covers the split ring, then insert the key into the

lineshaft. Raise the sleeve to the top of the key and secure the sleeve to the split ring with a lock screw and lock wire.

4. For threaded column, secure a friction clamp immediately below the column coupling. Hoist column section over bowl assembly. Lower column over lineshaft until column pipe engages the discharge bowl. Manually screw the column into discharge bowl. Complete joint by tightening column with chain tongs until the end of the column butts firmly against discharge bowl.

5. Lift the assembly and remove the elevator clamp or supports and slowly lower the bowl and the column assembly. Place supports on the base plate and continue to lower the assembly until the column elevator clamps or column flange comes to rest on the supports. Place an elevator clamp under the column pipe and allow it to butt firmly against the column pipe coupling.

6. Place the bearing retainer over the shaft and locate it in the column coupling recess. Make sure the end faces of the column pipe are clean.

7. Check that the shaft is approximately centered in the bearing. Move the shaft around slightly so as to center it in its bearing. Only a slight amount of force should be required. If an excessive amount of force is required, the pipe or shaft may not be butted properly or the shaft may be bent. In any case, the problem must be corrected prior to proceeding further.

8. Repeat the preceding procedures until all column sections required have been installed.

9. Install the top shaft or stub shaft and coupling. If the pump is equipped with column adjusting nipple,

install it with longer threaded end upward. (See page 13 for adjustment instruction.) Screw the lock

ring on to the nipple until reach to the end of the thread.

Do not drop any foreign object into the

column assembly. Such an object can cause serious damage to the pump and any downstream components. Any foreign object dropped into the column assembly must be retrieved prior to continuing assembly.

ENCLOSED LINESHAFT

1. Insert tube (654) and shaft (646) sections into

column section.

2. Place an elevator clamp near top of column just

below and butt firmly against column pipe coupling

(645). For flanged columns, place the elevator clamp

just below the flange.

3. Attach a sling to hoist hook. Attach bottom of shaft

(646) to column (644), by tying a tail rope to deepthroated clamp attached to bottom of column. (See Figure 6). Tie a clove hitch or double half hitch

around the enclosing tube and then around the shaft in threaded area. Figure 6 also shows the alternate

method (dotted lines).

4. Utilize the remaining tail rope to keep tension on

the knots during hoisting. Lower end of column section shall be guided by a drag line which is pulled by the hoist. A traveling block for the drag-line shall be attached to a deep-throated clamp, which is secured to bottom of the column threads.

5. Hoist column section over pump, keeping tension on tail rope. With column in a vertical position, remove drag-line and traveling block, lower column until bottom line shaft is properly aligned with pump shaft coupling.

6. Apply a thin film of oil to the threads on the

lineshaft (646) and the coupling (649) (for nongalling material or Molykote if galling material).

Use “MOLYKOTE” Dow Corning or equal for all galling material such as 316 stainless steel.

7. With lineshaft in proper position on the coupling, remove tail rope and screw lineshaft into coupling until resistance is felt. A fine wire inserted in the hole at the center of the coupling can be used as a gage to determine when the coupling is correctly positioned on the shaft. Remove the wire after installing the shaft. Complete tightening the joint by using a pair of pipe wrenches. Use care not to damage any bearing journal areas of the shaft.

NOTE: Shaft threads are left-handed.

Make up threaded joints manually to

verify that the threads are properly engaged prior to applying a wrench. If cross-threading occurs, break the joint and repair the threads. If the threads are beyond repair, replace the damaged part.

10. Lower column until column pipe engages in the discharge bowl. Manually thread the column into discharge bowl. Complete joint by tightening column, utilizing chain tongs until the end of the column butts firmly against discharge bowl.

11. Lift the pump assembly and remove elevator clamp secured to discharge bowl. Slowly lower assembly into well or sump until elevator clamp gently comes to rest on timbers or I-beam supports and remove the sling.

12. Remove the exposed lineshaft bearing, pour oil into the tubing and reinstall the bearing. The amount of oil to be poured is given in the following table:

Tube Size Amount of oil per section 10 ft. Sections 20 ft. Sections

1¼, 1½, 2 ½ Cup 1 Cup 2½, 3, 3½ 1 Cup ½ Qt. 4 and larger ½ Qt. 1 Qt.

See pages 19-20 for recommended oil.

13. Repeat the preceding procedures. Throughout

the column assembly, install tube stabilizer (658) over the enclosing tube (654) every 40 ft. The last

one should be less than 40 ft below the discharge head. Use soapy water as lubricant when sliding the stabilizer over the tube.

14. Continue the procedure until all column sections for the proper setting have been installed, excluding

the column adjusting nipple (631) and tube nipple (629), if provided.

15. Install the top shaft or stub shaft and coupling. If pump is equipped with column adjusting nipple and tube nipple, install them with longer threaded end

upward. Screw the lock ring (639) on to the column nipple until the end of thread. (See page 13 for adjustment instruction.)

Do not drop any foreign object into the

column assembly. Such an object can cause serious damage to the pump and any downstream components. Any foreign object dropped into the column assembly must be retrieved prior to continuing assembly.

8. Carefully lower column section until lower end of the tube section rests on the adapter bearing

(668). The end faces of the tube should be clean

and free of nicks. Remove tail rope, clean outside of the adapter bearing and lubricate with thread compound. Screw tube section onto adapter bushing manually, until resistance is felt. Complete tube joint by utilizing a pair of pipe wrenches or chain tongs, butting the end of tube against the upper end of the tube adapter bearing.

9. Clean column threads and lubricate with thread compound.

INSTALLING THE DISCHARGE HEAD

DWT Pumps are provided with either a cast iron or fab steel type head. Install the discharge head as follows:

1. If the stuffing box (See Figure 8) or tension nut (See Figure 9) is assembled to the head, remove it and all

the attached piping.

2. For threaded column, check to be sure that the

flanged column (637) is securely attached to the

bottom of the discharge head. Check and tighten

the capscrews (or socket head screw) gradually in

diametrically opposite pairs.

3. Remove coupling guard if provided. Attach a sling

CAUTION

to the lifting lugs on the side of the discharge head through windows and hoist discharge head over the

protruding top shaft (or stub shaft).

Do not bump or scrape the shaft protruding above the column. This could

result in bending or damaging the shaft.

4. Orient the discharge head in the required position and lower the head. Centering the vertical hole with the top shaft protruding above the column. For threaded column, continue to lower the discharge head until the large threaded hole in the bottom of the discharge head rests squarely on top of column. Clean the threads at upper end of column assembly and lubricate with thread compound. Rotate discharge head, screw it onto the column,

for short set-pump, (without the column adjusting nipple) butting the top of column tightly against the

discharge head.

7. Hoist the discharge head by lifting lug and remove the elevator clamp attached to column.

8. Remove the support timbers or I-beams and clean the top of foundation or base plate. Orient the discharge head in the required position.

NOTE: Sling should be rated to handle in excess of the

pump weight.

9. Lower bowl, column and head assembly, until discharge head mounting flange engages base plate. Secure discharge head to the foundation or base plate. Check the levelness of the discharge head in all directions, utilizing a machinist level across the driver’s mounting surface of the discharge head.

10. Check whether the top shaft (or stub shaft) is in

the center of the stuffing box bore. If not, the shaft must be centered by shimming the head base and

the sub base (or the foundation).

5. If pump has a column adjusting nipple (631), for

open lineshaft, screw the discharge head onto the column nipple until the end of the stub shaft is

“HT” below the face the driver mounting flange of the discharge head. (See Figure 7 for detail.)

For enclosed lineshaft, screw the discharge head

onto the column nipple until the “F” dimension is satisfied (See Figure 7). Tighten the lock ring (639).

6. For flanged column, continue to lower the discharge head until the discharge head engages the column. Install capscrews and secure discharge head to the column flange. Tighten capscrews gradually in diametrically opposite pairs. Lift pump assembly high enough to allow rotation of the supports. Realign and lower assembly. Install and tighten remaining capscrews. Repeat the rotating and the tightening procedure until all capscrews are uniformly tight.

11. Rotate the shaft approximately 90 degree. Check again whether the shaft is at the center of the stuffing box bore or not. If not, either the top shaft is bent or the first shaft below it did not butt properly. Correction must be made before the installation procedures can proceeds.

INSTALLING THE STUFFING BOX

Assemble stuffing box as shown in Figure 8.

1. Clean the surface of the discharge head where the stuffing box will be mounted and remove any nicks or burrs with a fine flat file. Position gasket

on surface. Slide stuffing box (616) down over

headshaft and into position on the gasket. Secure stuffing box with capscrews.

2. Grease the packing ring (620) for easier installation.

3. Twist the packing ring sideways to get it around the shaft easily. Start the first ring into the stuffing box. When the entire ring is worked in using the fingers,

tamp it down using a split wood bushing (or equal)

and push the packing ring down firmly. It must seal on the shaft and bore of the stuffing box. Install

three (3) rings in this manner. Stagger ring joints

90 degrees apart. The split gland may be used as a tamper for the top ring.

4. Insert lantern ring (622) into stuffing box. Be sure

it is properly positioned so that it aligns with the lubrication passage in the stuffing box.

5. Insert three (3) additional rings of packing. Stagger

ring joints 90 degrees apart.

6. Install the split gland and screw nuts on the split

CAUTION

gland studs. Tighten nuts then relieve the nuts and tighten finger tight. If discharge pressure is over 100 PSI, attach bypass line to the stuffing box bypass.

Check that the split gland is square in the

stuffing box. Cocking can cause uneven compression of packing and damage to the shaft or sleeve and heat up the shaft and stuffing box.

7. The stuffing box is shipped with both ports plugged.

If the discharge pressure is over 100 psi, remove the

plug on Port “A” and attach a bypass (relief) line. If

the discharge pressure is over 200 psi, remove the

plug on Port “B” and attach another bypass line.

9. A properly packed stuffing box should be loose enough to allow the shaft to be turned manually.

Do not over tighten packing or excessive wear can occur on the shaft or sleeve.

INSTALLING THE TENSION PLATE

Assemble Tension Plate Assembly as shown in Figure 9.

1. Remove the lock bolt (636) and o-ring (620).

Thoroughly clean the tension plate (625) including

the o-ring groove. Lightly grease the o-ring and reinstall it.

8. Final adjustment of the stuffing box must be made at pump start up.

INSTALLING THE DRIVER

INSTALLATION OF A HOLLOW SHAFT DRIVER

This refers to either VHS type electric motors or hollow shaft type gear drives. A small paragraph will be devoted to combination electric motor and right angle gear drives.

Do not work under a heavy suspended

object unless there is a positive support and safe guards which will protect personnel should a hoist or sling fail.

1. The driving mechanism of all hollow shaft driver is

shown on Figure 10. The driveshaft (608) extends

up through the quill or hollow shaft of the driver

and is held in place by an adjusting nut (604), which

not only carries all the static and hydraulic thrust of the impellers and shaft but also provides the adjustment for the impeller clearances. The head

shaft is connected to top shaft (or stub shaft) by a

threaded coupling or a rigid flange coupling.

2. Motor stand. When a motor stand is furnished and

not installed, proceed as follows:

A. Hoist the motor stand, inspect the mounting surfaces, register, and clean these surfaces thoroughly.

B. Install the motor stand on discharge head and secure with capscrews provided.

3. Attach a sling to the lifting lugs of driver and hoist

the driver up. Inspect the mounting surface, register and clean these surfaces thoroughly. If any burrs

Figure 11

6. After lowering and orienting the driver as explained above, remove the drive coupling and the hold

down bolts (See Figure 10). Be sure to mark the location of the coupling before remove it.

7. Lower the head shaft through the motor quill shaft to meet the shaft coupling. Apply a thin film of oil

to head shaft threads (if non-galling material) and screw into the shaft coupling (located above the stuffing box). Make sure the shaft is not damaged in

any way. Tighten the joint.

8. Check that the head shaft centers inside the driver

quill shaft within 0.06” (1.5 mm). If it does not,

misalignment is indicated.

9. Any head shaft misalignment with driver quill shaft could be caused by a bent driveshaft, burrs, or foreign matter between shaft ends or any of the mounting flanges: motor flange to discharge head top flange, discharge head base flange to base plate or the base plate itself could be out of level. If the latter, shimming between it and discharge head base, will correct it. Also, check concentricity of motor to

motor-stand (if provided) to discharge head.

10. With the motor in place and the head shaft projecting through the motor quill shaft, make temporary electrical connection to check the motor rotation. (Be sure to remove the ratchet pins (or balls) before checking motor rotation.) Motor must rotate counterclockwise when viewed from the top. See arrow on pump name plate. If motor does not rotate counterclockwise, you can change

the rotation by interchanging any two leads. (For

three phase only. For single phase motors see motor

manufacturer’s instructions.)

Never check motor rotation with the drive

CAUTION

coupling in place. The bore clearance between the drive coupling and the pump shaft O.D. is so close that should the motor spin with this shaft stationary, galling and locking together is very likely to take place.

11. Install motor drive coupling. (Be sure to line up the

match mark made at step 6.) Inserting the ratchet

pins if a non-reverse ratchet is used. Match the coupling lugs with corresponding holes in motor. Tighten hold down bolts evenly, making sure driver coupling is properly seated in the register fit.

12. Fit gib key (730) into keyway, by filing if necessary,

to where there is a snug but sliding fit. This key must be able to be removed by gentle leverage with a screwdriver under it.

13. Be careful that the gib key (730) is not too high so

as to hold up the adjusting nut (604) from seating

on the drive coupling. If it is, cut off some length of the key.

14. Install adjusting nut (604) to hand tight.

NOTE: 1.00" and 1.18" diameter shafts are 12 thread

per inch (tpi), 1.50" through 2.44" are 10 tpi, all larger sizes are 8 tpi.

For pump setting over 200 ft., continue to turn the

adjusting nut until impellers reach the top of bowls

(resistance is felt when impellers rub against the top of bowls.) The number of turns to reach the top

of the bowl should equal the total lateral obtained during bowl assembly installation as recommended in Paragraph 2 on page 10. If the lateral measured at the adjusting nut is less than that recorded previously, check the headshaft to make sure that the adjusting nut has not run out of threads and that the keyway is long enough. Also, check the shaft coupling or water slinger to make sure that neither one is being pulled up against the bottom of

the driver base. Now, lower the impellers (turn the adjusting nut clockwise) by 30% of the total lateral.

Line-up one of the holes in the adjusting nut with the nearest hole in the driver coupling. Insert the capscrew in the hole and tighten it.

For pump setting over 500 ft., consult factory for special instruction.

COMBINATION ENGINE AND MOTOR DRIVES

1. On combination drivers, the motor is invariably on

top with a projecting head shaft extension.

2. Follow all procedures outlined on page 15, except

that the motor must be lowered over this extended head shaft and great care must be taken to center it exactly so as not to bump or miss-align the shaft while the motor is being lowered into place.

3. There are several methods of running engines

without electric motors and vice versa, requiring simple adjustment to the combination drive, but they are too numerous to mention here and can be obtained from the gear manufacturers instructions included with the shipment.

IMPELLER ADJUSTMENT FOR ALL HOLLOW SHAFT DRIVES

NOTE: Shaft adjustment up or down is accomplished by

turning the adjusting nut (604) Figure 10.

NOTE: There are five holes in the adjusting nut and

only four in the motor coupling. See Figures 11.

1. With shafting all the way down and the impellers

resting on their seats, turn the adjusting nut (604)

in counterclockwise direction, thus lifting the shaft, until the impellers just clear their seats and the shaft/motor turns free by hand. This removes all

deflection from the shaft. (This is the “Shaft Pull-up in the Chart on page 14.)

2. For enclosed impellers, if pump setting is 200 ft. or

less, make another two turns on the adjusting nut

for the first 100 ft. (3 turns for 12 thread/inch shaft)

and one additional turn for each additional 50 ft. Line-up one of the holes in the adjusting nut with the nearest hole in the driver coupling. Insert the capscrew in the hole and tighten it.

3. For Open Impellers, Align hole “A” in the adjusting nut (604) and hole “C” in the driver coupling (See Figure11) or whatever similar holes are in like

position. If care is exercised, this will give an initial

impeller clearance of 0.001” to 0.003” depending

on shaft size or the pitch of the thread.

4. Insert capscrew into hole “B” provided these are

the nearest matching holes for counterclockwise rotation of adjusting nut, turn adjusting nut

counterclockwise until holes “B” and “D” line up. This gives 1/20 of a turn which is 0.004” on 12 tpi or 0.005” on 10 tpi shaft.

5. Normal impeller clearance for the open impeller is

LOWER IMPELLER

considered to be 0.015”

for the first 10 ft. of the

column length and 0.010”

additional clearance for each 10 ft. of length thereafter. This can be

reduced in some instances where is necessary, but should not be attempted without consulting the

factory or a factory serviceman if present.

WARNING

Pump Startup And Operation

PRE-START PROCEDURE

Consult the applicable manufacturer’s instructions for

detailed information for the prime mover (electric motor, engine or steam turbine), coupling, driveshaft, gear

driver. Prior to startup, check the following.

4. For oil lubricated pump, clean and fill the lubricator

tank with recommended oil. (See pages 19 and 20.)

Manually open the lubricator valve and allow oil to run into the shaft enclosing tube for at least 20

minutes for each 100 feet (30 meters) of setting

prior to start up. Then, adjust the lubricator for the proper drops per minutes according to the following table:

1. Confirm that the following procedures described

in the “Installing the Drivers” sections have been

performed:

A. Wiring of Driver.

B. Driver must rotate counterclockwise (CCW) when viewed from above.

Do not check motor rotation unless motor is bolted to pump and drive coupling is

removed.

Be sure to install the coupling guards

around all exposed shafts and couplings before start up of the pump. Failure to comply may result in sever personnel injury or death.

C. Check alignment of pump and driver. D. Impeller adjustment has been made.

2. For open lineshaft pump, make sure the stuffing box

bleed line is connected (if applicable). For enclosed

lineshaft pump, make sure the oil lubrication piping is connected and oil reservoir filled with the

recommended oil. (See pages 19 and 20.)

3. For open lineshaft pump, when a static water

level exceeds 30 feet (9 meters), pre-lubrication is

necessary. If it is equipped with a prelube system supplied from a pressurized header, open the supply valve and allow the prelube water to flow for 15

seconds plus 15 seconds per 100 feet (30 meters)

of pump setting. If it is equipped with a tank type prelube system, open the valve between the prelube tank and the pump and allow approximately half of the water in the tank to run into the pump before starting the pump. The pre-lube valve should remain open during the start up.

On the system equipped with a solenoid operated lubricator valve that cannot be energized independently, it will be necessary to remove the valve stem to allow the oil to flow into the tube. If the start up is delayed or the pump has been shut down for over 150 hours, the lubrication procedure must be repeated just prior to actual start up.

5. Open the air release system isolation valve. Adjusting the air release system throttling device so that is partially open, It should not be closed or fully open.

NOTE: Not exhausting the air or exhausting it too fast

can damage the pump.

6. All connections to driver and starting device must match wiring diagram. Voltage, phase and frequency on motor nameplate must agree with line current.

7. Rotate shaft manually to ensure impellers are not binding.

8. Verify that driver bearings are properly lubricated and check oil level in housing.

9. Inspect discharge piping connection, valves and pressure gauges for proper operation.

PUMP STARTUP

1. Partially close the valve in the discharge line.

2. Start the pump. If any abnormal noises, jerking or vibration is noted, stop the pump immediately, determine the cause of the abnormalities and correct them.

3. After the pump is operating at full speed, slowly open discharge valve. If driver overheats or there is excessive vibration, stop the pump, determine the causes and correct them.

4. If the air release valve is manually operated, close it.

5. For open lineshaft pumps, with the pump in

operation, there should be some leakage at the stuffing box packing. The correct leakage rate is approximately one drop per second. Check the temperature of the leakage as well as the discharge head. If the pump runs hot and the leakage begins to choke off, stop the pump and allow it to cool down. A few light taps with a hammer on the gland will upset the packing sufficiently to resume leakage. After pump has cooled, restart pump and follow preceding procedure. Run pump 15 minutes, check leakage, if it exceeds two drops per second, adjust

packing as described in “Packing Adjustment and Replacement”.

6. For enclosed line shaft pumps, adjust the lubricator valve for the proper flow rate of the lubrication oil.

(See Page 17.)

Preventive Maintenance

Preventive maintenance includes periodic inspection

of oil level in the oil reservoir (for pump with oil lub column), re-lubrication of electric motors, gear drives

and prime mover. Systematic inspection of the pump and its components shall be made at regular intervals. The frequency required depends upon the operating conditions of the pump and its environment. See Page 19 for Preventive Maintenance Procedures. Consult the applicable manufacturer’s instructions for detailed information on maintenance for the prime mover, driveshaft, electric motors and gear drives. Any deviation in performance or operations from what is expected can be traced to some specific cause. Variances from initial performance will indicate changing system conditions, wear or impending breakdown of the unit.

2. With the pump shut down and when packing has been compressed to the point that the gland is about to contact the upper face of stuffing box, remove the split gland, add one extra packing ring and readjust. If this fails to reduce leakage to two drops per second, remove all packing rings and replace with new rings.

Do not over tighten the stuffing box. Excessive pressure can wear out packing

prematurely and seriously damage the shaft.

3. Remove the packing with the aid of a packing hook. If a lantern ring is provided, remove it by inserting a wire hook in the slots of the ring and pull it from the packing box. Thoroughly clean the stuffing box of all foreign matter.

4. If the replacement packing is in the form of a continuous coil or rope, it must be cut into rings before installing. Tightly wrap one end of the packing material around the top shaft like one coil spring, and cut through the coil with a sharp knife.

For repacking sequence, refer to “Stuffing Box Installation” (page 13).

SEASONAL SHUTDOWN

Manually rotate shaft several times prior to restarting pump, which has been down.

1. For oil lubricated pumps that are shut down for an extended period of time, it is suggested that the pump be operated for at least 15 minutes every two weeks with oil feed wide open 2 hours before and during startup in order to maintain a film of oil on the shafting and shaft bearings.

Before initiating maintenance procedures,

disconnect all power sources to the equipment and accessories completely. Discharge all parts and accessories which retain electric charge. Failure to comply may result in severe personnel injury or death.

PACKING ADJUSTMENT AND REPLACEMENT

Pumps equipped with packing, shall be adjusted whenever the leakage rate exceeds two drops per second. If there is no leakage or the stuffing box overheats, do not back off gland nuts while the pump is running. This will allow the entire set of rings to move away from the bottom of the box, without relieving pressure of the packing on the shaft. Stop the pump and allow packing to cool then restart the pump.

Be sure to reinstall the coupling guard

before restarting the pump.

It may be necessary to repeat this procedure several times before proper amount of liquid comes through to efficiently prevent overheating. If leakage is excessive, adjust the stuffing box as follows:

1. With the pump in operation, tighten the gland nuts

one-quarter turn for each adjustment. Allow packing to equalize against the increased pressure and leakage to gradually decrease to a steady rate, before making another adjustment.

2. For product (or water) lubricated pump, if the pump

is to be shut down for an extended period of time, operate it for at least 15 minutes with adequate prelubrication every two weeks.

3. Before resuming normal operations, oil should be changed on drivers, right angle gear and lubricating oil system. After 15 minutes of operation adjust lateral.
