SAFETY WARNINGS
Specific to pumping equipment, significant risks bear reinforcement above and beyond normal safety precautions.
WARNING
A pump is a pressure vessel with rotating parts that can be hazardous. Any pressure vessel can explode, rupture, or discharge its contents if sufficiently over pressurized causing death, personal injury, property damage, and/or damage to the environment. All necessary measures must be taken to ensure over pressurization does not occur.
WARNING
Operation of any pumping system with a blocked suction and discharge must be avoided in all cases. Operation, even for a brief period under these conditions, can cause superheating of enclosed pumpage and result in a violent explosion. All necessary measures must be taken by the end user to ensure this condition is avoided.
WARNING
The pump may handle hazardous and/or toxic fluids. Care must be taken to identify the contents of the pump and eliminate the possibility of exposure, particularly if hazardous and/or toxic. Potential hazards include, but are not limited to, high temperature, flammable, acidic, caustic, explosive, and other risks.
WARNING
Pumping equipment Instruction, Operation, and Maintenance manuals clearly identify accepted methods for disassembling pumping units. These methods must be adhered to. Specifically, applying heat to impellers and/or impeller retaining devices to aid in their removal is strictly forbidden. Trapped liquid can rapidly expand and result in a violent explosion and injury.
ITT Goulds Pumps will not accept responsibility for physical injury, damage, or delays caused by a failure to observe the instructions for installation, operation, and maintenance contained in this Pump Safety Manual or the current IOM available at www.gouldspumps.com/literature.

Startup and Operation:
When installing in a potentially explosive environment, please ensure that the
motor is properly certified.
Operating pump in reverse rotation may result in contact of metal parts, heat
generation, and breach of containment.
Lock out driver power to prevent accidental start-up and physical injury.
The impeller clearance setting procedure must be followed. Improperly setting the clearance or not following any of the proper procedures can result in sparks,
unexpected heat generation and equipment damage.
If using a cartridge mechanical seal, the centering clips must be installed and set screws loosened prior to setting impeller clearance. Failure to do so could result
in sparks, heat generation, and mechanical seal damage.
The coupling used in an ATEX classified environment must be properly certified
and must be constructed from a non-sparking material.
Never operate a pump without coupling guard properly installed. Personal injury will occur if pump is run without coupling guard.
Make sure to properly lubricate the bearings. Failure to do so may result in excess
heat generation, sparks, and / or premature failure.
The mechanical seal used in an ATEX classified environment must be properly certified. Prior to start up, ensure all points of potential leakage of process fluid to
the work environment are closed.
Never operate the pump without liquid supplied to mechanical seal. Running a mechanical seal dry, even for a few seconds, can cause seal damage and must be
avoided. Physical injury can occur if mechanical seal fails.
Never attempt to replace packing until the driver is properly locked out and the coupling spacer is removed.
WARNING
WARNING
Dynamic seals are not allowed in an ATEX classified environment.
DO NOT operate pump below minimum rated flows or with suction and/or discharge valve closed. These conditions may create an explosive hazard due to

Alignment
Alignment procedures must be followed to prevent unintended contact of rotating
parts. Follow coupling manufacturer’s coupling installation and operation procedures.
SET UP
1. Mount two dial indicators on one of the coupling halves (X) so they contact the other coupling half (Y) (Fig. III-1).
2. Check setting of indicators by rotating coupling half X to ensure indicators stay in contact with coupling half Y but do not bottom out. Adjust indicators accordingly.
ANGULAR ALIGNMENT
A unit is in angular alignment when indicator A (Angular indicator) does not vary by more that .002 in. (.05 mm) as measured at four points 90° apart.
Vertical Correction (Top-to-Bottom)
1. Zero indicator A at top dead center (12 o’clock) of coupling half Y.
2. Rotate indicators to bottom dead center (6 o’clock). Observe needle and record reading.
3. Negative Reading - The coupling halves are further apart at the bottom than at the top. Correct by either raising the driver feet at the shaft end (add shims) or lowering the driver feet at the other end (remove shims), (Fig. III-2).
Positive Reading - The coupling halves are closer at the bottom than at the top. Correct by either lowering the driver feet at the shaft end (remove shims) or raising the driver feet at the other end (add shims).
Fig. III-1
MEASUREMENT
1. To ensure accuracy of indicator readings, always rotate both coupling halves together so indicators contact the same point on coupling half Y. This will eliminate any measurement problems due to runout on coupling half Y.
2. Take indicator measurements with driver feet hold-down bolts tightened. Loosen hold down bolts prior to making alignment corrections.
3. Take care not to damage indicators when moving driver during alignment corrections.
ANSIFAM IOM - 5/08

Fig. III-2
4. Repeat steps 1-3 until indicator A reads .002 in (.05 mm) or less.
Horizontal Correction (Side-to-Side)
1. Zero indicator A on left side of coupling half Y, 90° from top dead center (9 o’clock).
2. Rotate indicators through top dead center to the right side, 180° from the start (3 o’clock). Observe needle and record reading.
3. Negative Reading - The coupling halves are further apart on the right side than the left. Correct by either sliding the shaft end of the driver to the left or the other end to the right.
127
Page 26
3. Positive Reading - The coupling halves are
closer together on the right side than the left. Correct by either sliding the shaft end of the driver to the right or the other end to the left (Fig. III-3).
Fig. III-3
4. Repeat steps 1 through 3 until indicator A reads .002 in. (.05 mm) or less.
5. Re-check both horizontal and vertical readings to ensure adjustment of one did not disturb the other. Correct as necessary.
PARALLEL ALIGNMENT
A unit is in parallel alignment when indicator P (parallel indicator) does not vary by more than .002 in. (.05 mm) as measured at four points 90° apart at operating temperature. Note the preliminary vertical cold setting criteria, Table 1.
Vertical Correction (Top-to-Bottom)
1. Zero indicator P at top dead center of coupling (12 o’clock) half Y (Fig. III-1).
2. Rotate indicator to bottom dead center (6 o’clock). Observe needle and record reading.
Fig. III-4
NOTE: Equal amounts of shims must be added to or removed from each driver foot. Otherwise the vertical angular alignment will be affected.
4. Repeat steps 1 through 3 until indicator P reads within .002 in. (.05 mm) or less when hot, or per Table 1 when cold.
Horizontal Correction (Side-to-Side)
1. Zero indicator P on the left side of coupling half Y,
90° from top dead center (9 o’clock).
2. Rotate indicators through top dead center to the right side, 180° from the start (3 o’clock). Observe needle and record reading.
3. Negative Reading - Coupling half Y is to the left of coupling half X. Correct by sliding driver evenly in the appropriate direction (Fig. III-5).
Positive Reading - Coupling half Y is to the right of coupling half X. Correct by sliding driver evenly in the appropriate direction.
3. Negative Reading - Coupling half X is lower than
coupling half Y. Correct by removing shims of thickness equal to half of the indicator reading under each driver foot.
Positive Reading - Coupling half X is higher than coupling half Y. Correct by adding shims of thickness equal to half of the indicator reading from each driver foot (Fig. III-4).
Fig. III-5
NOTE: Failure to slide motor evenly will affect horizontal angular correction.
4. Repeat steps 1 through 3 until indicator P reads .002 in. (.05 mm) or less.
5. Re-check both horizontal and vertical readings to ensure adjustment of one did not disturb the other. Correct as necessary.

APPENDIX IV
Old JM Clipper CFT Design Labyrinth Seal Installation Instructions
Description of Operation
The labyrinth oil seal serves two functions. The first being to exclude environmental contamination from the power-end. This is accomplished with a series of tight clearance fits between the stationary and rotor. Any water that manages to enter the seal is eliminated from the seal through a drain slot located at the six o’clock position when installed.
On the oil side, a series of oil grooves are present to direct any oil between the shaft and stationary back into the oil sump through a drain slot at the six o’clock position.
®
O-rings are supplied as standard due to their
Viton chemical resistance. The stationary uses an O-ring to fit the labyrinth seal to the housing. The stator uses an O-ring to fit the labyrinth to the housing. The rotor uses an O-ring to seal along the shaft and to serve as the drive.
Installation Procedures
l
!
The ITT Goulds labyrinth oil seal is a one piece assembly. Do not attempt to separate the rotor and stator. Damage to the seal may result.
1. Assemble the power end per the instructions in Section 6 - Disassembly & Reassembly.
l
!
The edges of the keyway can be sharp. Failure to cover the keyway may result in a cut O-ring and a damaged seal.
2. Wrap tape around the coupling end of the shaft to cover the keyway.
CAUTION
CAUTION
3. Press the seal over the shaft into the thrust bearing housing or thrust bearing end cover by hand until the shoulder of the seal is seated against the housing/cover.
NOTE: An O-ring lubricant is not required, but can be used if desired. If used, be sure the lubricant is compatible with the O-ring material and plant standards.
4. For STX units: Press the seal over the shaft into the bearing frame by hand until the shoulder of the seal is seated against the frame.
For all other units: Once the frame adapter is installed on the bearing frame, press the seal over the shaft into the frame adapter by hand until the shoulder of the seal is seated against the adapter.
NOTE: An O-ring lubricant is not required, but can be used if desired. If used, be sure the lubricant is compatible with the O-ring material and plant standards.
NOTE: During start-up when the parts of the labyrinth oil seal establish a voluntary running clearance, a small amount of wear is experienced as the parts are in contact. This wear produces a carbon filled Teflon diameter of the seal and at the drain slot. This is the result of the two surfaces being smoothed, similar to burnishing. A lubricant should not be applied between the faces at installation. Once the running clearance has been established, no further wear is experienced and no decrease in seal performance occurs as a result of the carbon/

residue.

Alignment
A shaft alignment is not required when using the C-Face adapter. The rabbetted fits of the motor to the adapter and the adapter to the bearing frame automatically aligns the shaft to within the specified limits below.
The C-face motor adapter is intended for end users who need fast pump installation. A C-face adapter can attain a nominal alignment of 0.007 inches TIR. However, due to the stack up of machining tolerances of the various parts, the alignment can be as high as
0.015 inches TIR. Using a flexible, elastomer coupling like a Rexnord ES or Wood's Sureflex will provide acceptable pump and motor life under these alignment conditions.
To achieve the best Mean Time Between Pump Maintenance (MTBPM) requires shaft alignments of less than 0.002 inches (0.05mm). End users who require high pump and motor reliability are better served by using a foot mounted motor on a precision machined baseplate and performing a conventional alignment.

APPENDIX VIII
INPRO Labyrinth Oil Seal Installation Instructions
Description of Operation
The INRP VBXX-D®Labyrinth Oil Seal is specially designed to protect pump bearings from lubrication starvation as well as environmental contamination. The bearing is made up of three basic parts: the rotor (1), stator (2), and VBX over the shaft and is held in place by an elastomeric drive ring (4). The drive ring causes the rotor to turn with the shaft and provides a positive, static seal against the shaft. There is no metal-to-metal contact, therefore, no friction or wear concerns.
®
Ring (3). The rotor (1) fits
Intallation Procedures
! CAUTION
l
The INPRO VBX is a one piece design. Do not attempt to separate the rotor (1) from the stator (2) prior to or during installation.
1. Assemble the power end per the instructions in Section 6 - Disassembly and Reassembly.
l
! CAUTION
The edges of the keyway can be sharp. Failure to cover the keyway with tape may result in a cut o-ring and a damaged seal.
2. Wrap some electrical tape around the coupling end of the shaft to cover the keyway.
NOTE: The smooth surface of the electrical tape provides an excellent surface to slide the rotor O-ring over.
3. Lightly lube the shaft and rotor drive ring (4) with supplied lubricant.
NOTE: Lubricant will aid in the installation process. If used, be sure the lubricant is compatible with the O-ring material and plant standards.
4. Use an arbor press to install the outboard INPRO VBXX-D port (6) at the 6 o'clock position. Press it only as far as the beginning of the stator location ramp (9) and avoid angular misalignment. There is nominal 0.002" interference fit. Discard any residual material from the stator gasket (5).
For STX Units
5. Press the inboard seal over the shaft into the bearing frame as described in Step 4 above.
For All Other Units
