1.0 Introduction
This manual contains instructions and guidelines for
the installation, operation, maintenance, and storage
of the EMW Standard Pumps.
There are many factors affecting the successful
installation, operation, and maintenance of a pump.
There are variations in these factors per individual
pump; therefore, the information contained herein
shall only be used as a general guideline. If detailed
questions or problems arise, contact the Wilfley
Sales Office, Distributors, or Representatives.
It is important that this manual be read prior to
installation or start-up on the pump to understand
the safety, proper performance of the pump, and
maximum Mean Time Between Planned
Maintenance (MTBPM).
2.0 Safety Considerations
Centrifugal pumps can be dangerous if used
improperly. Any misuses may result in a pump that
does not function properly. A pump that does not
function properly may be a hazard and could cause
damage or injury.
For maximum safety and reliability, use only factory
supplied parts and follow all maintenance and
operating recommendations and instructions.
The following list is meant to be provided only as a
guide for some of the common types of misuse that
can damage a pump and/or cause injury and will
void any and all warranties.
1. Do not run a pump with the discharge valve
closed.
2. Do not run a pump in the reverse direction.
3. Do not start a pump that is “wind-milling” in the
reverse direction due to fluid flowing back
down the discharge pipe.
4. Do not continue to operate a pump when there
are indications that something is rubbing,
binding, or knocking.
5. Do not continue to run a pump that gives an
indication of overheating.
6. Do not operate a pump with any equipment
guard removed. Make sure all equipment
guards are correctly installed.
7. Do not operate a pump that is vibrating,
surging, or making an abnormal noise.
8. Do not work on a pump unless the drive
system is locked out and the pump is
disconnected from the drive system.
9. Do not connect the pump to the drive system
without verifying that the drive system is
running in the correct direction.
10. Do not rely on the factory’s alignment of the
pump and the drive system. Alignment may
have changed during shipment.
11. Do not change the pumping conditions or
installation of an EMW pump without
consulting ARW first to ascertain if the pump is
capable of handling the new conditions and/or
fluid.
12. Do not insert a cold liquid in or on a hot pump
or a hot liquid in or on a cold pump.
13. Do not hit a pump with any object.
14. Do not use worn or faulty parts.
15. Do not stick hands, arms, legs, or any other
object into the discharge, suction, or any other
opening of a pump.
16. Do not weld attachments to the pump.
17. Do not apply external heat to the pump.
18. Do not lift the pump by only its case or only its
bearing cartridge.
19. Do not examine a pump without using proper
eye, face, and toe protection.
20. Some materials deteriorate with time. If your
pump has been out of service for more than 3
months, please contact ARW for information
concerning its suitability for service.
The EMW pump has been designed and
manufactured for safe operation. In order to ensure
safe operation, it is very important that this manual
be read in its entirety prior to installation or operation
of the pump. ARW shall not be liable for physical
injury, damage, or delays caused by a failure to
observe these instructions.

Every pump has the potential to be dangerous due
to the following factors:
•Parts are rotating at high speeds.
•High pressures may be present.
•High temperatures may be present.
•Highly corrosive and/or toxic chemicals may
be present.
Paying close attention to safety is always extremely
important; however, there are often situations that
require special attention which are indicated
throughout this book by the following symbols:
DANGER – Immediate hazards that WILL result in
severe personal injury or death.
WARNING – Hazards or unsafe practices that
COULD result in severe personal injury or death.
CAUTION - Hazards or unsafe practices that

•Never apply heat to remove impeller.
•Observe all cautions and warnings highlighted
in pump instruction manual.
2.2 Unauthorized Modification and
Manufacture of Spare Parts
Modifications of the pump and/or pump parts are
only permitted with approval from the manufacturer.
Original spare parts and accessories authorized by
the manufacturer ensure safety. The use of other
parts can void any liability of the manufacturer for
damage or warranty.
2.3 Unauthorized Operation
Any warranty of the operating reliability and safety of
the pump/unit supplied is only valid if the machine is
operated in accordance with its designated use. The
limits stated in the data sheet must not be exceeded
under any circumstances.
3.0 Transport and Storage
Following proper transport and storage practices
prevents damage to pumping units.
3.1 Transport Requirements
Proper lifting and safety practices must be observed
at all times. Caution when lifting the pump as the
center of gravity is often located close to the stuffing
box/shaft seal area and not in the physical center of
the unit.
Units should be secured properly on a skid or crated
box.
3.2 Handling
The following describes how to suspension lift pump
components, assembled pumps, or pump, motor,
baseplate assemblies.
Lifting should only be done by trained personnel.
Pumps and motors often have integral lifting eyes or
eye bolts. These are intended for use in lifting the
individual piece of equipment.
Care should be taken to ensure all lifting lines
are properly installed to prevent a load shift. A
load shift may result in injury, death, or property
damage.
Do not lift pump using the bearing cartridge or
shaft as a hoist point.
Before lifting the equipment refer to the pump data
sheet for the complete assembly weight.
3.2.1 Bare Pump
Attach slings on pump case and pedestal. The
slings form three points for lifting as shown on the
next page. The sling lengths should be adjusted to
balance the load before attaching the lifting hook.
3.2.2 Pump and Overhead Assembly
Do not lift pump and overhead assembly with the
motor mounted on the overhead.

3.3 Storage Requirements
If the pump is inoperative for an extended of time,
flush the pump thoroughly and dry to minimize
corrosion. If there is a possibility of freezing, it is also
recommended to drain the lines and case. If the
pump is to be stored for more than 15 days, it should
be rotated once a week to lubricate and prevent
rusting of the bearings.
3.3.1 Short Term Pump Storage
•The pump/unit should be stored in a dry room
where the atmospheric humidity is at a
constant.
•If stored outdoors, the unit and crates must be
covered by waterproof material to avoid any
contact with humidity.
•All openings of the assembled pump/unit
components are closed and must only be
opened when required during installation.
•Protect all stored goods against humidity, dirt,
vermin, and unauthorized access.
3.3.2 Long Term Pump Storage
Follow the guidelines when the pump or parts will be
idle for a period of one month or more. Following
these simple steps while in storage will help to
extend the life of the bearing and related equipment
reliability.
1. All machined metal surfaces should be coated
with a suitable corrosion inhibitor to ensure the
integrity of these surfaces at the time of
installation.
2. All openings must be covered with suitable
covers to protect against contaminants.
3. Components and assemblies are required to
be stored indoors in a dry location.
Temperature range should be between 40
degrees Fahrenheit and 100 degrees
Fahrenheit.
4. When bearings are contained in equipment for
storage, a few steps should be taken to
ensure the preservation of bearing quality and
functionality. The two main concerns that
should be addressed are vibrations and
moisture. Vibration causes micro movements
between the bearing rolling elements and
raceways. This movement can displace the
protective lubrication between the balls and
raceways and lead to metal to metal cyclical
impacting. This is sometimes referred to as
false brinneling. Store the equipment as far as
possible from the source of vibrations (i.e.,
motors, rotating pumps, engines, etc.).
Isolating the equipment with rubber pads is
also an effective means of limiting vibrational
damage. Lastly, the bearings should be
rotated periodically so as to prevent extended
exposure to potential damage. The bearing
shafts should be rotated ten full rotations at a
minimum rate of once per quarter (90 days). If
high vibration levels are suspected then
rotating once per month is prudent. To protect
the bearings from moisture and contamination,
wrapping and taping the equipment in plastic
is recommended. If the environment is humid
(relative humidity over 70%) a suitable
desiccant should be used.
3.3.3 Parts Storage
Not all parts are packaged in a suitable manner from
the factory for long-term storage. To ensure a parts
satisfactory performance, the part must be protected
from corrosion and contamination.
3.3.4 Motor and Seal Storage
Refer to the respective manufacturer’s manuals for
storage instructions on the motor and seal.
4.0 Installation
4.1 Inspection upon Arrival
Your pump has been carefully inspected prior to
shipment to ensure that it meets the requirements.
Please inspect the pump upon arrival for any
damage that may have occurred during shipment,
and immediately report any damage to the carrier.
Leave all shipping covers attached to the pump unit
until it is ready for installation. If installation is to be
delayed more than 15 days, the pump shaft should
be rotated by hand once a week to lubricate the
bearings and prevent rusting.
4.2 Choosing Pump Location
1. Locate the pump as close to the liquid source
as possible so the suction pipe is short and
direct with a minimum of elbows, fittings, and
valves.

2. Place the pump in a location that allows easy
access to the unit for inspection during
operation and maintenance, which involve
removal and disassembly.
4.3 Foundation
The foundation should be sufficient to absorb any
vibration and form a permanent, rigid support for the
baseplate. A concrete foundation on a solid base is
satisfactory. Foundation bolts of the proper size
should be embedded in the concrete located as
indicated on the outline drawing.
4.4 Alignment
The pump and motor are aligned at the factory
before shipment. Realignment may be necessary
after the complete unit has been leveled on the
foundation and after the foundation bolts have been
tightened. Procedures for checking and aligning the
pump components are in section 4.10 and may also
be found in the Hydraulic Institute Standards.
4.5 Piping
All piping must be independently supported,
accurately aligned, and connected to the pump by a
short length of flexible piping. The pump should not
have to support the weight of the pipe or
compensate for misalignment. Install suction and
discharge bolts through mating flanges without
pulling or prying either of the flanges. All piping must
be tight. Pumps may air-bind if air is allowed to leak
into the piping. If the pump flange(s) have tapped
holes, select flange fasteners with thread
engagement at least equal to the fastener diameter
but do not bottom out in the tapped holes before the
joint is tight. The customer is responsible for proper
suction and discharge pipe design and layout to
avoid flow induced problems.
Piping Forces: Take care during installation and
operation to minimize pipe forces and/or
moments on the pump casing.
4.6 Discharge Piping
An isolation valve should be installed in the
discharge line to allow for pump inspection and
maintenance.
A rapidly closing discharge valve can cause a
damaging pressure surge. A dampening
arrangement should be provided in the piping.
4.7 Suction Piping
Care should be taken in sizing and locating suction
piping to prevent cavitation. A valve should be
installed in the suction line to prevent fluid from
flowing into the pump when it is shut down.
To avoid NPSH and suction problems, suction pipe
sizes must be at least greater than the pump suction
connection. Never use pipe or fittings on the suction
that are smaller in diameter than the pump suction
size.
The ideal piping configuration should have a
minimum of 10 pipe diameters between the source
and the pump suction. In most cases, horizontal
reducers should be eccentric and mounted with the
flat side on top or up with a maximum of one pipe
size reduction. Never mount eccentric reducers with
the flat side down. Horizontally mounted concentric
reducers should not be used if there is any
possibility of entrained air in the process fluid.
Vertically mounted concentric reducers are
acceptable. In applications where the fluid is
completely de-aerated and free of any vapor or
suspended solids, concentric reducers are
preferable to eccentric reducers.
Avoid the use of throttling valves and strainers in the
suction line. Start-up strainers must be removed
shortly after start-up. When the pump is installed
below the source of supply, a valve should be
installed in the suction line to isolate the pump and
permit pump inspection and maintenance. However,
never place a valve directly on the suction nozzle of
the pump. Refer to the Centrifugal Pump IOM
Section of the Hydraulic Institute Standards for
additional recommendations on suction piping.
4.8 Packing / Seal Flush Piping
An external connection should be made at the pump
so flush flow can be varied as required by valves
and the pressure can be monitored. Pipe fittings and
gauges must be corrosion resistant to the fluid being
pumped.

4.9 Piping Note
Refer to the Hydraulic Institute Standards for
centrifugal pumps for additional piping information.
4.10 Installation and Alignment
Accurate alignment of the equipment must be
obtained and sustained. Trouble-free operation can
be accomplished by following the proper
procedures.
A properly installed base plate will be leveled with
shims, retained in place with anchor bolts, set in
concrete, and grouted with a low shrinkage grout.
When a direct drive pump and motor is mounted to a
common base plate at the factory, the coupling is
installed and aligned at that time. However,
coupling alignment must be verified before operating
the pump and motor.
Proper coupling alignment can be verified by placing
a straight edge axially across the coupling halves.
The distance between the straight edge and the
shaft should be the same within 0.1 mm (0.004
inches). Also, the angular distance between the
coupling halves should be consistent within 0.1 mm
(0.004 inches). At a minimum coupling alignment
should be checked once every 90 degrees of shaft
rotation (12:00, 3:00, 6:00 and 9:00).
When checking a v-belt motor connection, the
parallel and offset alignment of the sheave(s) to
each other must be within 1.0 mm (0.040 inches).
After connecting piping, rotate the pump drive shaft
clockwise (viewed from motor end) by hand several
complete revolutions to be sure there is no binding
and that all parts are free. Recheck shaft alignment.
If piping caused unit to be out of alignment, correct
piping to relieve strain on the pump.
After making all piping connections verify pipe
strains haven’t altered alignment. If changes have
occurred, alter piping to remove pipe strains on
pump flanges.
Operate the pump for at least an hour or until it
reaches final operating temperature. Shut the pump
down and recheck alignment while the pump is hot.
Piping thermal expansion may change the
alignment. Realign the pump as necessary.
See the following table for possible alignment
issues.

5.0 Coupling and V-Belt Guard
Power must never be applied to the driver when
the coupling guard is not installed.
Coupling guards are safety devices intended to
protect workers from inherent dangers of the rotating
pump shaft, motor shaft, and coupling. It is intended
to prevent entry of hands, fingers, or other body
parts into a point of hazard by reaching through,
over, under, or around the guard.
No standard coupling guard provides complete
protection from a disintegrating coupling. The
coupling conforms to the U.S.A. standard ASME
B15.1, “Safety Standard for Mechanical Power
Transmission Apparatus.”
