A - GENERAL INFORMATION
TO THE PURCHASER:
Congratulations! You are the owner of one of the finest
pumps on the market today. These pumps are products
engineered and manufactured of high quality components.
With years of pump building experience along with a
continuing quality assurance program combine to produce
a pump which will stand up to the toughest applications.
Check local codes and requirements before installation.
Servicing should be performed by knowledgeable pump
service contractors or authorized service stations.
RECEIVING:
Upon receiving the pump, it should be inspected for
damage or shortages. If damage has occurred, file a claim
immediately with the company that delivered the pump.
If the manual is removed from the crating, do not lose or
misplace.
STORAGE:
Short Term - Pumps are manufactured for efficient
performance following long inoperative periods in storage.
For best results, pumps can be retained in storage, as
factory assembled, in a dry atmosphere with constant
temperatures for up to six (6) months.
Figure 1. Foundation Bolt Location and Anchorage
2. MOUNTING:
Pumps and drivers that are received from the factory
with both machines mounted on a common base plate,
were accurately aligned before shipment. All baseplates
are flexible to some extent and, therefore, must not be
relied upon to maintain the factory alignment. Preliminary
alignment is necessary after the complete unit has been
leveled on the foundation, and again, after the unit is
piped, and rechecked periodically as outlined in the
following paragraphs.
Long Term - Any length of time exceeding six (6) months,
but not more than twenty four (24) months. The units
should be stored in a temperature controlled area, a roofed
over walled enclosure that provides protection from the
elements (rain, snow, wind blown dust, etc..), and whose
temperature can be maintained between +40 deg. F and
+120 deg. F. Pump should be stored in its original shipping
container and before initial start up, rotate impeller by hand
to assure seal and impeller rotate freely.
Position unit on foundation and level the base plate,
using rectangular metal blocks and shims, or wedges
having a small taper as shown in Figure 2. A gap of 3/4”
to 1½” should be allowed between the base plate and
foundation for grouting.
SERVICE CENTERS:
For the location of the nearest Deming Service Center,
check your Deming representative or Crane Pumps &
Systems Service Department in Piqua, Ohio, telephone
(937) 778-8947 or Crane Pumps & Systems Canada, Inc.,
Bramton, Ontario, (905) 457-6223.
Adjust the metal supports or wedges until the shafts of
the pump and driver are level. Check the coupling faces,
as well as the suction and discharge flanges of the pump
for horizontal or vertical position by means of a level.
Correct the positions, if necessary, by adjusting the
supports or wedges under the base plate, as required.
B - INSTALLATION
1. FOUNDATION
The pump foundation should be sufficiently substantial
to form a level, rigid support for the combined weight
of the pump and driver and maintain alignment of the
installed unit. Foundation bolts, of the proper size, should
be imbedded in the concrete. A pipe sleeve, about 2½”
diameters larger than the bolt, should be used to allow for
final positioning of the bolts. See Figure 1.
NOTE: A flexible coupling should not be used to
compensate for misalignment of the pump and driver
shafts. The purpose of the flexible coupling is to
compensate for temperature changes and to permit end
movement of the shafts without interference with each
other, while transmitting power from the driver to the pump.
CAUTION! - Remove and lock out power to driver.
4
3. FIELD ALIGNMENT
The faces of the coupling halves should be spaced far
enough apart so that they cannot strike each other when
the driver rotor is moved toward the pump. The necessary
tools for checking the alignment of a flexible coupling are a
straight edge and a taper gauge or a set of feeler gauges.
ANGULAR
MISALIGNMENT
NOTE: In most cases where extreme accuracy is
necessary, a dial indicator may be used to align coupling.
Angular alignment check is made by inserting a taper
gauge or feelers between the coupling faces at 90-degree
intervals around the coupling. The unit will be in angular
alignment when the coupling faces are exactly the same
distance apart at all points. (See Figure 3).
Parallel alignment check is made by placing a straight
edge across both coupling rims at the top, bottom and
at both sides. The unit will be in parallel alignment when
the straight edge rests evenly on the coupling rim at all
positions. Allowance may be necessary for temperature
changes and for coupling halves that are not of the same
outside diameter. Care must be taken to have the straight
edge parallel to the axis of the shafts. Correction for
Angular and Parallel Misalignment is made by adjusting
the shims under the driver. After each change, it is
necessary to recheck the alignment of the coupling halves,
as adjustment in one direction may disturb adjustments
already made in another direction.
PARALLEL
MISALIGNMENT
The permissible amount of coupling misalignment will vary
with the type of pump and driver, but should be limited to
approximately .002 inches per inch of shaft diameter when
final adjustment is made. When the units are lined up cold,
it is necessary to make allowance for the vertical rise of
the driver caused by heating when in operation. When the
preliminary alignment has been completed the foundation,
bolts should be tightened evenly, but not too firmly.
WARNING - Coupling guards must be used to
avoid serious injury to operating personnel.
PERFECT
ALIGMENT
4. GROUTING
Grouting compensates for unevenness in the foundation
and prevents vibration and shifting after mounting is
complete. Build a form around the base plate to contain
the grout, and sprinkle area with water to obtain a good
bond. The base should be completely filled with a good
quality, non-shrinking grout. The usual mixture for grouting
is one part Portland cement and two parts sand with
sufficient water to flow freely. It is also desirable to grout
the leveling pieces, shims or wedges in place. Foundation
bolts should be fully tightened when grout has hardened,
usually about 48 hours after pouring.
Figure 3

Figure 4
5. PIPING
The pump suction and discharge connections are not
intended to indicate the required suction and discharge
pipe sizes. The pipe diameter must be selected according
to the requirements of the pumping system and
recommended friction losses for the liquid being pumped.
NOTE: A gate valve in the suction piping should not be
used as a throttling device, as this may cause the liquid to
overheat during operation.
FOOT VALVE
When it is advisable to install a foot valve to facilitate
priming, a spring loaded type check valve must be installed
next to the pump in the discharge line to prevent pump
rupture from water hammer shock. The foot valve should
have a clear passage for water not less than the same
area as that of the suction pipe. Care must be taken to
prevent foreign substances from being drawn into the
pump or chocking the foot valve. For this purpose an
effective strainer should be provided. When there is any
refuse such as sticks, twigs, leaves, etc., in the water, a
large outside screen should be placed around the suction
inlet to prevent chocking of the strainer. This screen should
have sufficient openings so that the flow velocity does not
exceed two feet per second or a free area of four to five
times the suction pipe area.
Usually, it is advisable to increase the size of both the
suction and discharge pipes at the pump nozzles to have
minimum acceptable friction loss, suction pipe should
never be smaller in diameter than the pump suction
nozzle. When suction pipe is of larger diameter than the
pump suction nozzle, an eccentric reducer is required to
eliminate possible air or vapor pockets at the pump suction
inlet.
Both suction and discharge pipes must be supported
independently near the pump, so that when piping is
connected to the pump, no strain will be transmitted to the
pump. Piping should be arranged with as few bends as
possible, and, preferably, with long radius elbow whenever
possible.
6. WIRING
For electric motor drives, connect power supply to conform
with national and local codes. Line voltage and wire capacity
must match the ratings stamped on the motor nameplate.
SUCTION PIPING
A horizontal suction line must have a gradual rise to the
pump. Any high point in the suction pipe can become filled
with air and prevent proper operation of the pump and may
cause loss of prime. The pipe and fittings must be free of
all air leaks.
7. ROTATION
Before starting the pump, check the required direction
of rotation of the pump. The proper direction is indicated
by a direction arrow on the pump casing. Separate the
coupling halves, then start motor to see that it rotates in
the direction required by the pump. If it does not, reverse
any two main leads of the 3-phase wiring to the motor.
The coupling halves can be reconnected and the pump
primed for starting.
Any valves or fittings should located at a distance equal
to 5 to 10 times the diameter of the suction pipe from the
pump suction nozzle. If an elbow must be installed at the
pump suction, it should be installed in a vertical position
to reduce unequal flow into the pump, which may cause
cavitation in the pump.

C - OPERATION
2. STARTING THE PUMP
On initial start up, the gate valve in the discharge piping
should be closed and slowly opened after pump is up to
speed and pressure developed. DO NOT operate pump for
any appreciable length of time against a closed discharge
valve, as this may heat trapped liquid excessively and
damage the pump or seal.
The following important items should be checked as pump
is started and placed in operation.
a. Pump and driver securely bolted
b. Coupling properly aligned
c. Piping complete
d. Correct pump rotation
e. Pump shaft turns freely
f. Discharge valve closed
g. Suction valve open (if used)
h. Coupling Guard installed
i. Pump fully primed
j. Pump and driver properly lubricated
k. Seal water valve open (if used)
l. Liquid drips slowly from packing gland
3. PUMP ADJUSTMENT
Open discharge valve as soon as operating speed has
been reached. After the pump has been started the
packing box glands should be tightened to eliminate
excessive liquid loss. (Applies only to pumps having
packed stuffing boxes.) Packing should not be pressed
too tight, as this may result in burning the packing and
scoring the shaft or shaft sleeve. The best adjustment will
allow the liquid to drip slowly from the packing box gland.
This will permit proper lubrication of the shaft and dissipate
generated heat.
Only after these items have been checked should the
pump be started.
As soon as the pump and driver have reached the normal
operating temperature, the unit should be shut down for
final coupling alignment. This should be done by following
the instructions found in Section B, Part 3. If correction
is necessary, it may be accomplished by the addition or
removal of shims from under the motor mounting feet.
1. PRIMING
CAUTION: Before starting the pump, the casing and
suction line must be filled with liquid, and air-vented
through the vent pipe plugs. The pump must not be run
until it is completely filled with liquid, because of danger of
injuring some of the parts of the pump which depend upon
liquid for lubrication.
D. MAINTENANCE
Be sure the stuffing box packing or mechanical seal and
power frame are supplied with the proper lubrication. See
LUBRICATION.
1. INSPECTION
Periodic inspection should be made of the following
components:
a. Bearing lubrication. Make sure the proper grade and
amount of lubrication is present. Section B and
Section D.
b. Packing should be lubricated with the proper
amount and type of acid-resistant lubricant.
c. A double seal should be lubricated with light oil,
clean water, or other compatible lubricating liquid.
d. All piping connections, gasketed joints and drains
should be checked for leaks.
e. Check bearings for excessive wear or failure. Worn
bearings may result in shaft run-out requiring
frequent replacement of packing or seal
f. Coupling alignment and lubrication must be
maintained for smooth operation and long coupling
life.
Pump priming may be accomplished by one of the
following methods. The discharge gate valve should be
closed during priming.
PRIMING BY SUCTION PRESSURE
When operating with suction pressure (flooded suction),
remove the pipe plug at the top of the casing and when
pump is filled with liquid, replace plug.
PRIMlNG WITH FOOT VALVE AND STRAINER
A foot valve and strainer may be installed on the lower end of
the suction pipe to keep pump filled with liquid. Incorporate
filler pipe in discharge pipe between pump and check valve.
Remove pipe plug at top of casing, then fill suction pipe and
pump with liquid. When pump is full of liquid, replace plug
and close filler pipe.
CAUTION: When a foot valve and strainer are installed on
the suction pipe, a spring loaded type check valve MUST be
installed next to the pump in the discharge piping to prevent
pump rupture from water hammer shock.
2. LUBRICATION
All pump and component parts have been lubricated at the
factory except pumps with oil lubricated bearings which
must be lubricated by filling oil reservoir through automatic
oiler.
Priming by means of primer pump or ejector, attached to
the pump, will also remove air from suction pipe and pump
casing. When pump is filled with liquid, start motor and
slowly open discharge gate valve.
Subsequent lubrication depends on operating conditions.
Periodic inspection of bearing lubrication is necessary and
additional grease or oil should be added as required.
7
f.
CAUTION: DO NOT over grease bearings or
add excess oil
Reassemble shaft coupling. Place pump in
operation and check power required to be certain
impeller does not rub casing.
The following lubricants are recommended at the operating
temperature indicated:
NOTE: The Fig. 4160 Series with enclosed impeller
normally does not require adjustment of the impeller.
Oil lubricated Bearings - S.A.E. #10 Wt. Non-detergent oil
4. PACKING BOX CARE
Pumps are normally furnished with grease fittings (243)
for packing lubrication and with the internal water seal
passage blocked. If operating with suction lift and clean
liquid the socket type pipe plug (263) may be removed
and the liquid being pumped will then form a water seal at
the lantern ring.
Grease Lubricated Bearings - Shell Alvania #2 or equal.
Packing boxes - Lithium base grease
Double Seal - Pressurized water or light oil circulated
thru seal chamber. If pressurized liquid is not available,
Shell Alvania EPRO #71030 grease may be used with
pressurized grease cup.
Driver and Coupling - See manufacture’s recommendations.
When installing new rings of packing, clean packing box
(11) and inspect parts for any damage. If the shaft sleeve
(14) is worn or grooved, it should be replaced. New
packing will not do an adequate sealing job on a worn
shaft sleeve.
SINGLE SEAL
Pumps with single seals are normally furnished with
an internal by-pass open (See cross section). A small
portion of the liquid being pumped is recirculated from
the casing through the seal chamber to act as a lubricant
and coolant. For hot water service at temperatures above
180ºF the by-pass should be plugged and seal chamber
cooled with water through a heat exchanger or from an
outside source.
Insert two new rings of packing in front of lantern ring.
Stagger joints to minimize leakage. Tamp each ring in
place. Replace lantern ring. Add two rings of packing
behind lantern ring. Replace gland (17) and bolts (209),
rotate shaft and tighten gland securely. Loosen the gland
and add the final ring of packing. Be sure lantern ring is
positioned to receive lubrication through item (243) orifice.
Tighten nuts securely to seat packing and rotate shaft.
After rotating several turns, loosen nuts (210) to finger
tight for starting.
DOUBLE SEAL
On double seal applications, clear liquid under pressure
must be circulated thru the seal chamber at approximately
20 pounds above the maximum pressure that may occur
on the inner seal. This may be accomplished with clear
liquid from outside source, liquid from pump discharge
thru a filter or thru exchanger if liquid is over 180ºF.
IMPORTANT! - Liquid being pumped should drip
slowly but constantly through the packing and
gland. This will prevent overheating, high power
consumption, and shaft sleeve damage.
3. IMPELLER ADJUSTMENT - Fig. 4060 Series
An outstanding feature of this pump is the axial adjustment
of the impeller to compensate for eventual wear or corrosion.
Correct impeller adjustments will insure optimum operating
performance and effiencies.
Lubricate through grease fitting (243) or by removal of
fitting and substituting tubing and on outside source of
water or oil.
5. DISASSEMBLY
The disassembly instructions apply to the series of
pumps in general and may vary slightly on special units.
If complete disassembly is not necessary, use only those
steps which apply.
To adjust impeller clearance:
a. Disconnect power supply to the driver and disengage
shaft coupling.
b. Loosen the three lock nuts and jack screws (204)
and (286) then tighten the three cap screws (213)
evenly, by alternating cap screws, until the impeller
vanes just rub against the casing (1) when the
shaft is rotated by hand. It may be necessary to
bump the shaft on the coupling end to make sure
that the impeller is against the casing.
c. Tighten the jack screws (286), finger tight against the
power frame (19), then loosen cap screws (213).
d. Tighten the jack screws an additional 1/3 turn
(2 hex) to obtain .016” to .020” impeller clearance.
The clearance may be measured with feeler gauge
thru suction inlet of the casing (1).
e. Carefully tighten cap screws (213) and lock nuts
(204) then rotate shaft by hand to make certain that
impeller does not rub against casing.
Close gate valve in discharge and suction piping. Inspect
all parts removed to determine whether suitable reuse. It
is recommended that all packing, gaskets and o-rings be
replaced with new ones during reassembly.
NOTE: Special precautions must be observed when
handling mechanical seals so as not to damage the
lapped faces of the seal.
Unless casing (1) is damaged or it is necessary to replace
wearing ring (7), it may not be necessary to remove the
suction and discharge piping from the casing to service
