INTRODUCTION
This manual is furnished to acquaint you with some of the practical ways to install, operate, and maintain
this pump. Read it completely before doing any work on your unit and keep it handy for future reference.
Equipment cannot operate well without proper care. To keep this unit at top efficiency, follow the recom-
mended installation and servicing procedures outlined in this manual. The SAM Engineering Customer
Service Department is available to expertly guide the installation of the pump for maximum operating life
and minimum downtime.
PUMP IDENTIFICATION (NAMEPLATE)
These pumps are designated by serial number, model, size, and M.O.C. This information is stamped on an
identification plate and affixed to the pump frame or casing.
Permanent records are kept by the factory and filed by serial number.
The pump nameplate contains the following information:
1. SERIAL NUMBER – Composed of certain groups of numbers. All groups are necessary for
identification. TYPICAL EXAMPLE: P 2081 / 98
2. MODEL – CSR, followed by SIZE – Composed of three (3) groups of number.
EXAMPLE: 4 x 3 x 11 – First number (4) is the ASA suction flange size in inches, second number (3) is
the ASA discharge flange size in inches, the third number (11) is the nominal maximum impeller
diameter in inches.
3. IMPELLER DIAMETER – This number is the impeller diameter in millimetres as supplied by the factory.
EXAMPLE: 265
4. FLOW – Design flow rate in cubic metres per hour.
5. HEAD – Design head in metres.
6. MAX. DESIGN PRESSURE – This refers to factory standard hydrostatic test pressure for hydraulic end
of pump.
7. M.O.C. – Material of construction of pump shown in abbreviated form and in four parts.
EXAMPLE: CI/SS/CI/EN8 – where casing, stuff box and wear plate (if fitted) are in Cast Iron / impeller
in Stainless Steel / frame is in Cast Iron / shaft is in EN8
8. RPM – Design speed of pump to achieve design flow and head.

INSTALLATION
RECEIVING PUMP
Check pump for shortages and damage immedi-
ately upon arrival. (An absolute must!) Prompt
reporting to the carrier's agent, with notations
made on the freight bill, will expedite satisfactory
adjustment by the carrier.
Pumps and drivers are normally shipped from the
factory, mounted on a baseplate. Couplings may
either be completely assembled or have the
coupling hubs mounted on the shafts and the
connecting members removed. When the connect-
ing members are not assembled, they will be
packaged in a separate container and shipped with
the pump or attached to the baseplate.
Shafts are in alignment when the unit is shipped;
however, due to shipping, the pumps may arrive
misaligned and, therefore, alignment must be
established during installation. SAM Engineering
has determined that proper and correct alignment
can only be made by accepted assembly practices.
Refer to the following paragraphs on "Foundation",
"Setting Baseplate", "Grouting Procedure",
"Alignment Procedure", and "Doweling".
STORAGE
Short term: (Less than 6 months) SAM Engineering
normal packing procedure is designed to protect
the pump during shipping. Upon receipt, store in
a covered and dry location.
Long term: (More than 6 months) Preservative
treatment of bearings and machined surfaces will
be required. Rotate shaft several times every 3
months. Refer to driver, coupling and seal
manufacturers for their long-term storage
procedures. Store in a covered, dry location.
LOCATION
The pump should be installed as near the suction
supply as possible, with the shortest and most
direct suction pipe practical. The total dynamic
suction lift (static lift plus friction losses in suction
line) should not exceed the limits for which the
pump was sold.
The pump must be primed before starting.
Whenever possible, the pump should be located
below the fluid level to facilitate priming and
assure a steady flow of liquid. This condition
provides a positive suction head on the pump. It is
also possible to prime the pump by pressurising
the suction vessel.
When installing the pump, consider its location in
relation to the system to assure that sufficient Net
Positive Suction Head (NPSH) at pump suction is
provided. Available NPSH must always equal or
exceed the required NPSH of the pump.
The pump should be installed with sufficient acces-
sibility for inspection and maintenance. A clear
space with ample headroom should be allowed for
the use of an overhead crane or hoist sufficiently
strong to lift the unit.
NOTE: Allow sufficient space to be able to disman-
tle pump without disturbing the pump inlet and
discharge piping.
Select a dry place above the floor level wherever
possible.
Make sure there is a suitable power source avail-
able for the pump driver. If motor driven, electri-
cal characteristics should be identical to those
shown on motor data plate.
SETTING BASEPLATE/PEDESTAL
The foundation surface will support the pump and
driver with shims and plates under the baseplate
at the foundation bolts. The foundation should be
smooth and level at these points to distribute the
load evenly on the shims. A thin metal plate
levelled in a puddle of mortar or grout is often the
easiest way to achieve this level and smooth
surface. Use thick shims wherever possible to
reduce the number of shims used.
ALIGNMENT PROCEDURE
The pump and driver have been checked at the
factory to determine that field alignment dimen-
sionally can be made. Shims and dowels are
packaged separately and shipped with the pump.
It is mandatory that the unit be field aligned since
any baseplate, regardless of size or style, can be
warped in shipment or when installed on a founda-
tion. Generally, any type of coupling can be used
if aligned properly.
SUCTION AND DISCHARGE PIPING
When installing the pump piping, be sure to
observe the following precautions:
a) Both the suction and discharge piping should
be independently supported near the pump
and properly aligned so that no strain is
transmitted to the pump when the flange bolts
are tightened. Use pipe hangers or other
supports at necessary intervals to provide
supports.
4

Suction and Discharge Piping
b) It is usually advisable to increase the size of
both suction and discharge pipes at the pump
connections to decrease the loss of heat from
friction.
c) Install piping as straight as possible, avoiding
unnecessary bends. Where necessary, use
45-degree or long-sweep 90-degree fittings to
decrease friction losses.
d) Make sure that all piping joints are air-tight.
e) Where flanged joints are used, assure that
inside diameters match properly.
f) Remove burrs and sharp edges when making
up joints.
g) Do not “spring” piping when making any
connections.
h) Provide for pipe expansion when hot fluids are
to be pumped. The use of expansion joints is
not recommended.
When installing the suction piping, be sure to
observe the following precautions:
a) Suction piping should be short in length, as
direct as possible, and never smaller in
diameter than the pump suction opening. If
the suction pipe is short the pipe diameter can
be the same size as the suction opening. If
longer suction pipe is required, pipes should
be one or two sizes larger than the opening
depending on piping length.
b) To facilitate cleaning, pump liquid passage
without dismantling pump, an increasing
suction nozzle (available from Allis-Chalmers)
should be bolted to the suction flange. If this
is not done, a short section of pipe so
designed that it can be readily dropped out of
the line can be installed adjacent to the suction
flange. With this arrangement, any matter
clogging the impeller is accessible by removing
the nozzle (or pipe section).
The suction pipe should slope upward to the
pump nozzle. A horizontal suction line must
have a gradual rise to the pump. Any high
point in the pipe will become filled with air and
thus prevent proper operation of the pump.
When reducing the piping to the suction
opening diameter use an eccentric reducer
with the eccentric side down to avoid air
pockets.
Note: Never use a straight taper reducer in a
horizontal suction line, as it tends to form an air
pocket in the top of the reducer and the pipe.
When installing valves in the suction piping,
observe the following precautions:
a) If the pump is operating under static lift
conditions, a foot valve may be installed in the
suction line to avoid the necessity of priming
each time the pump is started. This valve
should be of the flapper type rather than the
multiple spring type, sized to avoid excessive
friction in the suction line. (Under all other
conditions a check valve, if used, should be
installed in the discharge line.)
b) When foot valves are used, or where there are
other possibilities of “liquid hammer”, close
the discharge valve before shutting down the
pump.
c) Where two or more pumps are connected to
the same suction line, install gate valves so
that any pump can be isolated from the line.
Install gate valves with stems horizontally to
avoid air pockets. Globe valves should not be
used, particularly where NPSH is critical.
d) The pump must never be throttled by the use
of a valve on the suction side of the pump.
Valves should be used only to isolate the pump
for maintenance purposes, and should always
be installed in positions to avoid air pockets.
DISCHARGE PIPING - If the discharge piping is
short, the pipe diameter can be the same as the
discharge opening. If the piping is long, pipe
diameter should be one or two sizes larger than
the discharge opening. On long horizontal runs it
is desirable to maintain as even a grade as possi-
ble. Avoid high spots, such as loops, which will
collect air and throttle the system or lead to erratic
pumping.
VALVES IN DISCHARGE PIPING - A check valve
and grate valve should be installed in the
discharge. The check valve, placed between pump-
and gate valve, protects the pump from excessive
pressure, and prevents liquid from running back
through the pump in case of power failure. The
gate valve is used in priming and starting, and
when shutting the pump down.
PRESSURE GAUGES - Properly sized pressure
gauges can be installed in both the suction and
discharge nozzles in the gauge taps (which are
provided on request). The gauges will enable the
operator to easily observe the operation of the
pump, and also determine if the pump is operat-
ing in conformance with the performance curve. If
cavitation, vapour binding or other unstable opera-
tion should occur, widely fluctuating discharge
pressure will be noted.

Discharge Piping | Stuffing Box
EXTERNAL-INJECTION LIQUID-SEAL PIPING
a) A tapped hole is supplied in the stuffing box
directly over the seal cage to introduce a clean,
clear sealing liquid. The stuffing box must at
all times be supplied with sealing liquid at a
high enough pressure to keep the box free from
foreign matter, which would quickly destroy the
packing and score the shaft sleeve. The sealing
liquid must be left on even when the pump is
shut down, unless the casing is isolated from
the discharge pressure.
b) Only a sufficient volume of sealing liquid to
create a definite direction of flow from the
stuffing box inward to the pump casing is
required, but the pressure is important.
c) We recommend that piping supplying sealing
liquid of stuffing box be sized to supply a
sufficient volume of water at the required
pressure, based on the location of the pump
(or pumps) with respect to the liquid source. A
small pipe can be utilised for the connection to
the stuffing box. A valve should be installed to
adjust and regulate sealing liquid and a gauge
installed to check pressure.
d) External sealing liquid should be adjusted to
the point where packing runs only slightly
warm, with a very slow drip from the stuffing
box. Excess pressure from an external source
can be very destructive to packing. More
pressure is required, however, for abrasive
slurries than for clear liquids. Examination of
the leakage will indicate whether to increase
or decrease external pressure. If slurry is
present in the leakage, increase the pressure
clear liquid drips from the box. If the drippage
is corrosive or harmful to personnel, it should
be collected and piped away.
e) A common error is to open the external piping
valve wide and then control the drippage by
tightening the packing gland. Actually, a
combination of both adjustments is essential
to arrive at the optimum condition. The life of
packing and sleeve depends on this careful
control more than any other factor.
STUFFING BOX
Contaminants in the pumped liquid must not enter
the stuffing box. These contaminants may cause
severe abrasion or corrosion of the shaft, or shaft
sleeve, and rapid packing or mechanical seal
deterioration; they can even plug the stuffing box
flushing and lubrication system. The stuffing box
must be supplied at all times with a source of
clean, clear liquid to flush and lubricate the pack-
ing or seal. The most important consideration is to
establish the optimum flushing pressure that will
keep contaminants from the stuffing box cavity. If
this pressure is too low, fluid being pumped may
enter the stuffing box. If the pressure is too high,
excessive packing or seal wear may result; and
extreme heat may develop in the shaft causing
higher bearing temperatures. The most desirable
condition, therefore, is to use a seal water pressure
slightly above the maximum stuffing box pressure.
STUFFING BOX OPERATING PRESSURE - The
actual stuffing box pressure operating pressure
may be obtained by installing a pressure gauge on
the box. This should be done with an extra seal
cage temporarily replacing the two rings of pack-
ing in the bottom of the box to obtain a more
accurate gauge reading. Gauge readings should be
taken with the pump running under various head
and capacity conditions. The pressure of the
flushing or lubrication water can then be set at a
value 5 to 10 psi above the maximum expected
stuffing box operating pressure. Even under the
best conditions, a properly packed stuffing box
should be watched closely. If pressure conditions
change slightly there will be resistant change in
packing “seating” which should be compensated
by a change in gland adjustment.
FLUSHING AND LUBRICATION WATER – The
recommended method to minimise error in
regulating flushing water is the “Controlled
Pressure System”. Most important is the pressure
reducing valve which may be adjusted to a value
slightly exceeding the stuffing box operating
pressure. A flow indicating device that will serve to
indicate a failing of the bottom packing rings
allowing leakage into the pump. is advisable eith
this arrangement, the packing gland need s to be
tightened only against the lowest necessary
pressure. The “out” connection from the stuffing
box should be closed with this system. Longer
packing life and less frequent adjustment are
possible with the “controlled pressure system”
properly installed and operated.

OPERATION
PRE-START CHECKS
Before initial start of the pump, make the
following inspections:
1. Check alignment between pump and motor.
2. In the desired direction, check rotation each
time motor leads have been disconnected.
3. Check all connections to motor and starting
device with wiring diagram. Check voltage,
phase, and frequency on motor nameplate with
line circuit.
4. Check suction and discharge piping and
pressure gauges for proper operation.
5. Turn rotating element by hand to assure that it
rotates freely.
6. Check impeller clearance.
7. Assure that pump bearings are properly
lubricated.
8. Assure that pump is full of liquid.
PRIMING
If the pump is installed with a positive head on the
suction, it can be primed by opening the suction
and vent valve and allowing the liquid to enter the
casing.
If the pump is installed with a suction lift, priming
must be done by other methods such as foot
valves, ejectors, or by manually filling the casing
and suction line.
NOTE: Under either condition, the pump must be
completely filled with liquid before starting. The
pump must not be run dry in the hope it will prime
itself.
STARTING
1. Close drain valves.
2. Fully open all valves in the suction and
discharge lines.
3. If pumped fluid is dirty, these lines should
always be left open except when using double
mechanical seals.)
4. Prime the pump.
NOTE: If the pump does not prime properly, or
loses prime during start-up, it should be shut down
and the condition corrected before the procedure
is repeated.
5. (Pumps moving high temperature liquids).
Open the warm-up valve to circulate liquid for
preheating. Close the valve after the pump is
warmed up.
6. Start the pump driver (turbines and engines
may require warming up; consult the
manufacturer's instructions).
7. When the pump is operating at full speed,
check to see that the check valve has opened
up. Check valve must open 5 seconds or less
after start-up to prevent damage to pump by
operating at zero flow.
8. Adjust the seal water valves to produce the
recommended pressure for either the
mechanical seal or packed stuffing box.
Note: The valve in the discharge line should always
be closed when the pump is started. The excessive
current required by the motor to start under full
load will in time cause motor trouble.
SHUTDOWN
The following steps will take care of most normal
shutdowns of the pump. Make any further adjust-
ments of process piping, valves, etc., as required.
If the pump is to be removed from service for an
extended period of time, refer to "Storage", and
"Freeze Protection".
1. Close the discharge valve slowly.
Note: When stopping pump, always close discharge
valve first.
2. Shut down the driver (consult manufacturer’s
instructions for special operations).
3. Close seal water valves. (If pumped liquid is
dirty, or if in leakage is to be prevented, these
lines should always be left open, except when
the pump is completely drained.)
4. Open drain valves as required.

MAINTENANCE
GENERAL MAINTENANCE AND PERIODIC INSPECTION
Operating conditions vary so widely that to recommend one schedule of preventative maintenance for all
centrifugal pumps is not possible. Yet, some sort of regular inspection must be planned and followed. We
suggest a permanent record be kept of the periodic inspections and maintenance performed on your pump.
This recognition of maintenance procedure will keep your pump in good working conditions, and prevent
costly breakdowns.
One of the best rules to follow in the proper maintenance of your centrifugal pump is to keep a record of
actual operating hours. Then, after a predetermined period of operation has elapsed, the pump should be
given a thorough inspection. The length of this operating period will vary with different applications, and
can only be determined from experience. New equipment, however, should be examined after a relatively
short period of operation. The next inspection period can be lengthened somewhat. This system can be
followed until a maximum period of operation is reached which should be considered the operating
schedule between inspections. See Maintenance Time Table below.
8
NOTE: The above time table is based on the assumption that after start up, the unit had been
regularly monitored and such a schedule was found to be consistent with operation, as shown by
stable readings. Extreme or unusual applications or conditions should be taken into
consideration and may require shorter maintenance intervals.

INSPECTION
Check bearing temperature with a thermometer, not by hand. If bearings are running hot (over 180°),
it may be the result of too much lubricant. If changing the lubricant does not correct the condition,
disassemble and inspect the bearings.
Check grease lubricated bearings for saponification. This condition is usually incurred by the infiltra-
tion of water or other fluid past the bearing shaft seals and can be noticed immediately upon inspec-
tion, since it gives the grease a whitish colour. Wash out the bearings with a clean industrial solvent
and replace the grease with the proper type, as recommended.
Check the packing and replace if necessary. Use the grade recommended. Be sure the seal cages are
centred in the stuffing box at the entrance of the stuffing box piping connection.
Check shaft or shaft sleeve for scoring. Scoring accelerates packing wear.
Check alignment of pump and motor. Shim up units if necessary. If misalignment recurs frequently,
inspect the entire piping system. Unbolt piping at suction and discharge flanges to see if it springs
away, thereby indicating strain on the casing. Inspect all piping supports for soundness and effective
support of load.
Remove the rotating element. Inspect thoroughly for wear, and order replacement parts if necessary.
Check wearing clearances between impeller inlet and suction cover or between impeller wear ring and
suction wear plate...
Remove any deposit or scaling. Clean out stuffing box piping.
Measure total dynamic suction and discharge head as a test of pipe connection. Record the figures
and compare them with the figures of the last test. This is important especially where the fluid being
pumped tends to form a deposit on internal surfaces. Inspect foot valves and check valves, especially
the check valve which safeguards against water hammer when the pump stops. A faulty foot or check
valve will also reflect in poor performance of the pump while in operation.

Troubleshooting
No liquid delivered
CAUSES CURES
1. Lack of prime
2. Loss of prime
3. Suction lift too high
4. Discharge system head too high
5. Speed too low
6. Wrong direction of rotation
7. Impeller completely plugged
Fill pump and suction pipe completely with liquid.
Check for leaks in suction pipe joints and fittings; vent
casing to remove accumulated air.
If no obstruction at inlet, check for pipe friction losses.
However, static lift may be too great. Measure with
mercury column or vacuum gauge while pump operates.
If static lift is too high, liquid to be pumped must be
raised or pump lowered.
Check pipe friction losses. Larger discharge piping
may correct condition. Check that valves are wide open.
Check whether motor is directly across-the-line and
receiving full voltage. Alternatively, frequency may be
too low; motor may have an open phase.
Check motor rotation with directional arrow on pump
casing. Wrong rotation will cause pump damage.
Dismantle pump or use piping hand hole to clean impeller.
Not enough liquid delivered
8. Air leaks in suction piping
9. Air leaks in stuffing box
10. Speed too low
11. Discharge system head too high
12. Suction lift too high
13. Impeller partially plugged
14. Cavitation; insufficient NPSH
(depending on installation)
15. Defective impeller
16. Defective packing
If liquid pumped is water or other non-explosive material,
and explosive gas or dust is not present, test flanges for
leakage with a flame or match. For such liquids as
gasoline, suction line can be tested by shutting off or
plugging inlet and putting line under pressure. A gauge
will indicate a leak with a drop of pressure.
Increase seal lubricant pressure to above atmosphere.
See item 5.
See item 4.
See item 3.
See item 7.
a. Increase positive suction head on pump by lowering pump
or increasing suction pipe size or raising fluid level.
b. Sub-cool suction piping at inlet to lower entering liquid
temperature.
c. Pressurise suction vessel.
Inspect impeller. Replace if damaged or vane sections
badly eroded.
Replace packing and sleeves if badly worn.

10
Not enough liquid delivered
CAUSES CURES
17. Foot valve too small or partially
obstructed
18. Suction inlet not immersed deep
enough
19. Wrong direction of rotation
20. Too small impeller diameter
(probable cause if none of the
above)
Area through ports of valve should be at least as large as area
of suction pipe, preferably 1½ times. If strainer is used, net
clear area should be 3 to 4 times area of suction pipe.
If inlet cannot be lowered, or if eddies through which air is
sucked persist when it is lowered, chain a board to suction
pipe. It will be drawn into eddies, smothering the vortex.
Compare rotation of motor with directional arrow on
pump casing. Wrong rotation will cause pump damage.
Check with factory to see if a larger impeller can be used;
otherwise, cut pipe losses or increase speed, or both, as
needed. Be careful not to seriously overload drive.
Troubleshooting
Not enough pressure
21. Speed too low
22. Air leaks in suction piping
23. Mechanical defects
24. Obstruction in liquid passages
25. Air or gases in liquid (Test in
laboratory, reducing pressure on
liquid to pressure in suction line.
Watch for bubble formation.)
26. Excessive impeller clearance
27. Too small impeller diameter
(probable cause if none of
the above.)
See item 5.
See item 8.
See items 15, 16, and 17.
Dismantle pump and inspect passages of impeller and
casing. Remove obstruction.
May be possible to overrate pump to the point where it will
provide adequate pressure despite condition. It is better to
provide gas separation chamber on suction line near pump,
and periodically exhaust accumulated gas. See item 14.
Adjust impeller clearance.
See item 20.
Pump operates for a short time, then stops
28.Incomplete priming
29.Suction lift too high
30.Air leaks in suction piping
31.Air leaks in stuffing box
32.Air or gases in liquid
Free pump, piping and valves of all air. If high points in
suction line prevent this, they need correcting.

Machine impeller's OD to size advised by factory.
See item 14.
See items 15, 16, and 17.
See item 18.
Use larger driver. Consult factory for recommended size.
Test liquid for viscosity and specific gravity. See item 6.
Release gland pressure. Tighten reasonably. If sealing
liquid does not flow while pump operates, replace
packing. If packing is wearing too quickly, replace scored
shaft sleeves and keep liquid seeping for lubrication.
Check alignment. Examine pump for friction between
impeller and casing. Replace damaged parts.
Check for pipe strain.
Check alignment. Examine pump for friction between
impeller and casing. Replace damaged parts. Check for
pipe strain.
Dismantle pump and inspect shaft.
Check bearings and impeller for damage.
Any irregularities in these parts will cause a drag on the shaft.
Realign pump and driver.
Check voltage on motor.
The voltage and frequency of the electrical current may
be lower than that for which the motor was built: or there
may be defects in the motor. The motor may not be
ventilated properly due to a poor location.
If trouble cannot be located, consult factory.
