SPECIFIC GRAVITY
Changes in product specific gravity will
affect required horsepower and discharge
pressure. Fluids with higher specific gravities will
require more horsepower to operate, which
could lead to an overload condition on the unit
driver.
SPEED
Changes in speed affect the total differential
head, capacity and brake horsepower. See
formula below.

NET POSITIVE SUCTION HEAD (NPSH)
NPSH is the total suction head in feet of the
pumpage at the centerline of the impeller eye,
less the absolute vapor pressure of the liquid
being pumped. The NPSHR is the suction head
required to cover suction losses. Refer to the
pump curve for this information. The NPSHA is
the available suction head measured above
product vapor pressure. Failure to have
adequate margin of NPSHA over NPSHR will
cause cavitation and damage to pump internals.
INSTALLATION
RECEIVING INSPECTION
This unit was inspected prior to shipment.
The unit should be inspected to ensure that no
damage has occurred during transportation.
Some components may have been boxed and
shipped along with the unit, or secured to the
unit. The unit packing list should be consulted to
ensure that no loss of components has occurred
during shipment.
Any loss or damage should be immediately
reported to the carrier and a representative of
PumpWorks 610.
SHORT TERM STORAGE
Unless specifically designated by contract
for long term storage, this unit has setup for
short term storage for a period not more than 6
months from date of manufacture.
When the pump is received, the pump
should be thoroughly checked to make sure all
sealing covers and plugs are still intact. This is
to prevent moisture, windblown particles,
insects, and varmits from entering the pump and
bearing housings.
If there is a base plate involved, it should be
supported in a manner to prevent base
distortion. This is to prevent putting undue stress
on the base running the risk of a permanent set
in a distorted condition. The lower base plate
flange should be elevated and not in contact
with the ground. Sloping top base plates should
be stored in a manner to prevent moisture from
accumulating.
If there is only a pump involved, it should be
supported on a shipping, storage frame, or
cribbage that will provide equal support under all
pump feet. Check to make sure all vent and
drain holes are plugged to prevent entry of
insects and contaminants.

Model: PWD Rev. B_12/2/2015
Although not imperative, PumpWorks 610
recommends covering the unit with a quality
canvas or nylon tarpaulin. This will help prevent
exposure to the elements and contaminants
facilitating a clean pump for later installation.
Electric motor manufacturers recommended
short term storage procedures should be
followed for the unit driver. If after receipt of the
unit, a longer period of storage is required,
consult factory for storage recommendations.
LONG TERM STORAGE
As with short term storage, the unit is
shipped with covers and plugs to prevent
moisture, windblown particles, insects, and
varmits from entering the pump and bearing
housings. All exposed machined surfaces will be
coated with a preservative to prevent oxidation.
The type of coating will be predicated on the
location and environmental conditions of the
location the pump is going to be stored in.
Check to make sure coated surfaces have not
been wiped clean due to windblown tarps during
shipment. If so they need to be recoated with a
good quality grease or rust preventative.
Base plates and pumps should be supported
as described above in short term storage
section. PumpWorks 610 recommends covering
the unit with a quality canvas or nylon tarpaulin.
Fill the pump bearing housings to the bottom
of the shaft with Royal Purple VP 10 or
equivalent vapor phase rust inhibitor. If the unit
is a force fed lube type system then all piping
will have to be filled as well to accomplish this. If
the dual mechanical seal system contains any
carbon steel parts, it should be filled with a
barrier fluid that is compatible with the process.
For carbon steel and low alloy pumps, the
casing should be filled with Royal Purple VP 10
or equivalent vapor phase rust inhibitor.
Mark the coupling or shaft with a distinct
marking at “0”, “90”, “180”, and “270” degrees.
When marking is complete set the element with
“0” at top center. This for a reference for rotating
the element to prevent permanent sag set in the
shaft due to the weight of the element. The
element will need to be routinely rotated as
specified below. Do not spin the element!
Rotate it only as outlined. The product acts as a
lubricant for the wear rings, and spinning of the
element dry could cause galling of the wear
parts. Rotation is to be done once a week,
always rotate in the same direction. After the
pump has been in storage for one month rotate
it for 2 ¼ turns. This allows coating of the shaft
with the preservative oil. Continue this weekly
process until the pump is installed. If the pump is
in storage for more than six months then each
six month period the oil needs to be drained out
of the bearing housings and fresh oil added.
This is to remove any moisture that may collect
in the system during storage.
Electric motor manufacturers recommended
long term storage procedures should be
followed for the unit driver. The motor shafts for
magnetically centered rotors are usually secured
during shipment. If these are removed for rotor
rotation, they should be reinstalled prior to
shipping or lifting.
FOUNDATION
The design of the foundation is the
responsibility of the customer. The following
sections on the foundation, leveling and grouting
are given as reference, and do not constitute
complete instructions for the installation and
setting of the base plate. PumpWorks 610
suggest contacting a firm experienced in the
foundation design and installation of base
plates, if internal company resources are not
available.
The foundation must be rigid enough to
prevent settling and eventual distortion of the
base plate and pump. A proper foundation is

Model: PWD Rev. B_12/2/2015
important to help prevent vibration and
resonance problems. The preferable foundation
material is reinforced concrete. The concrete
should be poured far enough in advance to
assure it has sufficient time for drying and
curing. Approximate cure times required for
standard cement is 21 to 28 days. Approximate
cure time for High Early Strength cement is 7
days minimum. The concrete manufacturer
should be consulted for actual cure times. For
the anchor hole locations, reference the General
Arrangement drawing, if a base plate is supplied
by the factory. A bolt sleeve should be used
around the anchors to allow minor adjustment of
the anchors. See Figure 1
The concrete should be prepared by
chipping off approximately 1” of the top surface
to remove all laitance. This should be done with
hand chipping guns only, and no jack hammers.
The concrete should be dry and free of oil, dust
and debris.
When a pump is to be mounted on a
structure or base plate, it should be designed so
that the pump support is under the pump feet.
The structure must be rigid enough to prevent
springing or deflection and eventual distortion of
the base and pump.
LEVELING
The foundation should be cleaned of loose
concrete, oil, grease, and debris, and per grout
manufacturer preparation instructions.
PumpWorks 610 base plates are manufactured
with leveling screws on the bottom flange, near
the anchor holes. These should be utilized with
a steel jack plate for leveling of the base plate.
The bottom flange of the base plate should be
raised off of the foundation approximately 1 1/2”
to allow for grouting. A precision level, transit, or
laser should be used to accurately level the
base plate in all directions, and to ensure that
there is no twist or bow between the driver and
pump pads. Once leveled, snug the anchor bolts
down. Do not tighten completely until grout is
applied and cured
GROUTING
PumpWorks 610 standard epoxy primer is
compatible with Escoweld 7505E/7530 Epoxy
Grout. The grout manufacturers detailed
instructions on site preparation and installation
of the product should be followed. The anchors
and jack screws should be wrapped or protected
from adherence to the grout.
PIPING RECOMMENDATIONS
Piping design is the responsibility of the end
user. The suction piping should be of ample size
to prevent restrictions to the suction and
discharge of the pump. The suction piping
should have 8x (pipe diameter) in straight run to
the first elbow. Bends in the suction and
discharge piping should be kept to a minimum.
The suction piping should be flushed prior to
installation of the final suction piping to the
pump. It is assumed that the pumpage consist of
clean fluids, yet even with the pumpage of clean
fluids, scale can come loose from the pipe
internals over time.
A suction strainer is highly recommended,
as scale, welding slag, dirt, and trash can
severely damage pump internals. The suction
strainer should be installed in a spool piece for
ease of removal. The suction strainer should not
be placed directly against the pump suction
flange, but should be a minimum of 5 pipe
diameters from the pump’s suction flange
Pressure indicators should be used on either
side of the strainer to monitor a pressure drop
across the strainer. A strainer will not prevent
smaller particles from passing through the
pump, and because of this, the starting and
stopping of the unit should be minimized.
A possibility on coast down exists that small
particles can become trapped between the
rotating and stationary components, and bind or
gall the internal wear parts. If this occurs, under
no circumstance should excessive force be

Model: PWD Rev. B_12/2/2015
Fi
g
ure 2
applied to turn the element, as this could cause
further, and possibly severe damage to the
internal components. The rotating element
should be pulled from the pump casing, and the
internal wear parts and rotor cleaned.
Piping to the pump should be supported to
prevent excess nozzle loads. Please refer to a
certified copy of the general arrangement
drawing for allowable piping forces and
moments values. These values are for
operational allowances and are not given to
excuse excessive pipe strain.
Excessive pipe strain can adversely affect
alignment, and the subsequent life of the pump.
LIFTING
The lifting of the complete pump should be
done on the body of the casing, inboard of the
bearing housing hanger brackets. Do not
support directly on the bearing housings as this
could affect the alignment of the rotating
element in relationship to the internal stationary
parts. Do not try to lift the complete pump by the
top half “cast” lifting lugs. The cast lifting lugs in
the top half casing is designed for lifting of the
top half only.
The motor should be lifted per the motor
manufactures recommended lifting instructions.
Normally the lifting lugs provided on the top of
the motor are adequate for lifting. Magnetically
centered rotors should be secured to prevent
movement of the rotor, and subsequent damage
to the sleeve bearings. The rotors are normally
secured with a bracket on the drive end shaft
extension.
For the lifting of the complete skidded
package, lifting lugs are provided on the skid,
which per API are capable of lifting the entire
package. A spreader bar is recommended for
lifting of the entire unit. Refer to a certified
general arrangement drawing for lifting weights
and center of gravity of the unit.
PUMP INSTALLATION
Normally the pump is secured to the base
plate upon shipment. However, if the was not
shipped on the base plate, or was removed
during the grouting process, the pump should be
lifted and positioned on the pedestals, centering
the foot mounting holes. The pump is to mount
directly on the pedestals, without the use of
shims.
The pump mounting feet should be checked
to ensure that no soft foot condition exists.
During base shipment, lifting, and installation
processes, distortion of the base plate could
occur. With a dial indicator, check each foot by
setting the indicator in a vertical position, zeroing
the dial, and tightening the foot bolt. Record the
reading and loosen. Move to the next foot and
repeat. When all feet are checked, a minimal
amount of shims should be added to the “soft”
feet, only as necessary to eliminate the soft foot
condition. Shims should be stainless steel, and

Model: PWD Rev. B_12/2/2015
should be of sufficient size to support the pump
foot. The foot bolting can then be tightened to the proper torque. Refer to standard torque charts,
or consult the factory if necessary.
DRIVER INSTALLATION
Once the driver has been mounted on the
base plate pedestals, the retaining bracket on
the drive shaft can be removed, if applicable. It
is important to inspect the shaft for runout. In
many cases, the motor will have a coupling hub
mounted on the driver from the factory. A check
by a dial indicator on the rim and face of the
coupling should be performed to ensure no
damage or warpage to the rotor has occurred.
The tolerances for runout should not exceed
.002” concentric (Rim), and .001” angular
(Face).
Set the motor to the magnetic center mark
and check the distance between shafts. Refer to
the general arrangement drawing for the proper
distance setting.
It is important to check the motor rotation
prior to coupling the units for operation. It may
be necessary to couple the units for alignment
purposes, but the motor should be uncoupled
and bump tested to ensure proper rotation prior
to operation.
PumpWorks normally allows approximately
.25” height difference for shimming of the motor.
Rough align the motor and check the motor for a
soft foot condition. The soft foot procedure is
described in the pump installation section above.
The total number of shims per foot should be
limited to 5 shims to prevent shim springing.
During the final alignment, considerations for
thermal growth of the driven equipment should
be considered. This includes vertical thermal
growth of the motor, as well as vertical and
horizontal growth of a driven gearbox.
ALIGNMENT
Proper alignment is important for the
longevity of your equipment. Although reverse
indicator alignment, and rim and face indicator
alignments can produce satisfactory results,
PumpWorks 610 strongly advises that laser
alignment equipment be utilized for the
alignment of this equipment.
Alignments should be performed by qualified
and experienced personnel. It is up to the end
user to ensure that all safety procedures,
especially lock out / tag out procedures, are
followed.
Motor rotation should be verified prior to
alignment, however, if initial alignment is
performed prior to checking the motor rotation,
the coupling of the driven unit should be
disengaged from the driver immediately after
alignment is performed. Motor rotation should
then be checked prior to reinstallation of the
coupling.
For motors with magnetically centered
rotors, ensure that the rotor is on magnetic
center and adjust to the proper end to end
distance between the shafts. Refer to the
General Arrangement Drawing as necessary for
the proper dimension. Ensure that no “soft foot”
condition exists on the motor or pump, if this has
not been performed. See the section “Pump
Installation” above for instructions on this
procedure.
The pump hold down holes should be
centered and torque to the proper torque value.
The motor bolts should have a minimum of 1/8”
clearance to the motor/driver mounting holes for
adjustment.
For laser alignments, the coupling spacer
needs to be installed for the final alignment.
Consideration should be taken for the vertical
thermal expansion of the motor. If a gearbox is
utilized, thermal expansion in the vertical and
horizontal directions should be compensated for.
The motor and gearbox manufacturers should
be able to supply expansion growth dimensions.
In the absence of such dimensions, the equation
for thermal expansion is expressed as follows:
Height / width (in inches) x Temperature Change (Ambient – Operating Temperature) x .0000067 (growth
coefficient)

Model: PWD Rev. B_12/2/2015
A “Hot Alignment” should be performed
to verify proper alignment after unit has
reached and stabilized at normal operating
temperatures. Records of cold alignment
settings, and adjustments during hot
alignments should be kept to facilitate future
installations. Tighten all bolting, take new
readings and verify that the alignment values
repeat.
Note: Direct sunlight on the laser lens can
effect alignment readings, as well as
wear in gear tooth couplings.
Readings on gear couplings should be
made in one direction of rotation, to
eliminate backlash errors.
COUPLINGS
Each coupling type have their inherit
strengths and weaknesses. For that reason,
couplings should be selected on a basis of
operating conditions, thermal growth,
maintenance requirements, and operating
speed.
With the BB3 style pump, a coupling spacer
is necessary for the removal of the inboard
mechanical seal, without disturbing the pump or
driver. During seal replacement and normal
maintenance schedules, couplings should be
inspected for wear, disc warpage or cracking,
and signs of a poor fitting taper.
On taper fit shafts, fretting of the coupling fit
and wear of the shaft key is a sign of a poor
fitting coupling. When a shaft or coupling hub is
replaced new, the fit to the mating part should
be inspected to ensure a proper fit. This can be
done with high spot blue, or chalk. With high
spot blue, apply a thin layer in a line down the
length of the taper fit of the shaft or coupling
bore. Without the key in the shaft, ease the hub
on the taper fit and twist approximately 5° to 10°.
Pull the hub off and inspect the contact pattern
of the taper on the mating part. The contact
pattern should be reasonably uniform down the
length of the taper.
Improper fitting coupling can cause shaft
wear or breakage at the coupling fit. When
replacing a hub or shaft, ensure drive key has
clearance over the top of the key as to not
prevent hub makeup on the shaft taper fit.
LUBRICATION
Several methods of providing lubrication to
bearings are employed in pump lube systems.
The type of bearings used in the pump and
design specifications dictate which type of
system is used. The three primary lube systems
are:
Pressurized lube system: This system
involves an external lube oil pump with a
reservoir and filtering system. The oil is
circulated through the lube oil reservoir,
through a heat exchanger, then through the
filtering system, then to the bearing
housings. From the bearing housings, the oil
drains back into the reservoir. This type of
system will be fitted with controls to monitor
pressures and temperature and shut the unit
down in the event of a failure in the system.
Oil rings will be utilized in most cases on the
sleeve bearings for coast down of the pump.
Tilting pad bearings will always be pressure
fed. See Figure 3 for typical housing
arrangement.
This system has an auxiliary lube
pump to supply oil to the pump until the
pump is up and running. After the pump is
up and running the main lube oil pump,
which is in most cases attached to the pump
shaft, provides the lube oil supply and the
auxiliary lube pump shuts down.
Prior to starting, the auxiliary lube oil
reservoir should be filled to the specified
level with oil. This level will be indicated by a
sight gauge on the tank itself. This system
should be started and ran for at least one
hour prior to startup of the pump. If the
pump is in a cold climate the heater should
be turned on several hours prior to start up
in order to raise the temperature of the oil to
an acceptable level. Monitor the filter
differential pressure during this period, and if
there is more than a 2 PSI increase in this
pressure, the system should be run until this
pressure does not change for at least one
hour. At this time the active filter should be
changed out if there was a pressure
increase.
Once the lube system is purged per the
above, the pump can be started, (see start
up procedures).

Model: PWD Rev. B_12/2/2015
Ring oil lubricated: This system utilizes
slinger rings running in, or near the bearings
to pick oil up from the bearing housing oil
reservoir and deposit it on the shaft. The oil
then is transferred to the bearings by means
of channeling and/or catch-drip type
devices. If it is required, heat exchangers or
fans can be added to these type units to
maintain acceptable lube oil temperatures.
See Figures 4 & 5.
Units equipped with constant level oilers
are adjusted at the factory to the proper
level prior to shipment. However, the level
should be checked prior to operation. The oil
level mark is either cast into the housing, or
marked on an oil level tag which is attached
to the housing. If the tag is missing, refer to
factory supplied documentation. This oil
level dimension is from the shaft centerline
to the level of the oil in the bearing housing,
which also correlates to the top of the star
nuts. If it is necessary to adjust the star nuts,
loosen and adjust to the proper height, and
secure the bottom jam nut. Fill the bearing
housing reservoirs to the required oil level.
Fill oil bottle and position them on the star
nuts and secure with thumb screws.
Oil mist: With this type of lubrication system
the oil reservoir is separate from the pump.
The bearings are lubricated by an oil vapor
that is forced through the bearings. This type
of system will run cooler than most as there
is a small film of oil on the bearings

Model: PWD Rev. B_12/2/2015
therefore there is less friction to create heat.
There is also a flow of air across the
bearings that helps dissipate heat. This type
of lubrication is only used on roller type
bearings.
The oil mist system is operated by an air
supply. This air is utilized to vaporize the oil.
Activate this system and let if function for
one half hour prior to starting the pump. To
verify the mist system is functioning properly
there will be a smoke-like fog coming from
the bearing housings. Make sure this mist is
visible prior to starting the pump.

Unfiltered oil should be changed after the
first 250 hours initial startup. The frequency of oil
changes during normal operations varies upon
quality of oil, operating conditions, and
environment. Oil is subject to gradual
deterioration due to moisture, heat and
contaminates. Excessive deterioration of the oil
could cause damage and premature failure of
the bearings and bearing journals. Oil levels
should be checked on a weekly basis during
normal operations and replenished as required.
Sampling of the oil is highly recommended to
ensure the oil quality.
A pump shut down for more than 3 weeks
should have the bearing lubricated prior to
startup. For oil ring lubricated bearings, oil can
be applied directly to the bearing and/or shaft
through the inspection plugs.
In the case of pumps with lubrication
systems, the oil system should be run for
approximately 30 minutes twice a month to
prevent moisture contamination.
For idle equipment, oil temperatures should
be maintained above 60°F (16° C) in cold
weather. For oil reservoirs utilized in locations of
extended periods of cold temperatures, and/or
on equipment which is on standby for extended
periods, a tank heater is suggested to maintain
acceptable temperatures for startup.
Loss of lubrication can result in a bearing
failure which can cause a mechanical spark.
Care in maintaining lubricant levels should be
followed according to these procedures.

operation. Heating time should be not
over 100°F per hour of temperature
change until the case reaches within
100°F under the product temperature.
The case should be allowed sufficient
time to normalize in temperature. As a
rule of thumb, allow a minimum of 1
hour per inch of thickness at the thickest
point of the case (normally the parting
flange). If the components are heated
too rapidly and/or the components are
not given enough time to normalize in
temperature, warpage due to uneven
thermal expansion can cause the rotor
to bind in the internal stationary rings.
Starting in this condition could damage
the internal components. Heating is
usually performed with a warm-up or
bypass line. The suction valve is to be
open as not to over pressure the case.
Open the warm-up line to allow a small
amount of hot fluid to circulate through
the pump.
11) Ensure all guards are in place at the
coupling and over seal glands, as
applicable.
STARTUP PROCEDURES
Pump should be vented at the high points of
the casing, suction and seals prior to operation.
Failure to properly vent entrapped air can cause
damage to the mechanical seals and pump
internals.
With the discharge valve closed, slowly
open the suction valve and allow product to
enter the pump. Open vent valves to remove all
air from the pump. Unit will be fully vented when
fluid runs clear with no bubbles.
Once the pump is primed, If no bypass valve
or line is used, set the discharge valve at 10%
open. If a minimum flow bypass line or actuator
valve is used for start-up purposes, the
discharge valve may be closed. Ensure that
valves on the minimum flow line are open.
Note: When the pump is located above
suction source the discharge valve
cannot be opened until the drive has
been started since this would cause
loss of prime.
Start the pump. As soon as it begins to
develop pressure, start slowly opening the
discharge valve. Avoid making any abrupt
change in discharge velocity in order to prevent
surging within the piping. Surging can cause
serious damage to the internals of the pump.
The pump should reach discharge pressure
as soon as it reaches operating speed. If does
not happen, shut the pump down immediately.
Re-vent and prime the pump and try re-starting.
START-UP INSPECTION
Pull bearing housing inspection plugs and
check the slinger rings at the bearings to insure
that they are rotating and picking up oil. If any of
them are not, shut the unit down immediately
and investigate the cause of the problem.
1) For auxiliary oil systems, check oil flow
through sight flow indicators in the drain
lines.
2) Check for seal leakage. If a minor leak
does not stop after a few minutes of
operation, shut the unit down and re-set
seal. Seal failure can cause a
mechanical spark. Follow preventative
maintenance schedule.
3) Check for leaks in all the piping, vents
and drains, suction and discharge, lube
oil, etc.
4) Monitor bearing housing and oil
temperatures to ensure proper bearing
and oil temperatures. Shut down if there
is a sudden temperature rise, or if
temperatures continue to rise past the
desired operating range.
5) Monitor oil levels and ensure that there
is no leakage at the bearing isolators.
6) On auxiliary oil systems, observe during
startup to ensure auxiliary pump to main
pump cutover. Monitor oil pressures to
ensure constant and within the proper
operating parameters.
7) Monitor differential pressures across the
filters on auxiliary oil systems. Change
filters as necessary.
8) Monitor differential pressure across the
suction strainer. Shutdown and clean as
necessary if there is an increase of 5
psig or more.
9) Monitor vibration readings, especially
those attributed to misalignment. A hot
alignment may be necessary to adjust
for thermal growths.
10) Monitor vibration readings, especially
those attributed to misalignment. A hot
alignment may be necessary to adjust
for thermal growths.
