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. Rotate shaft by hand
approx. every 30 days.
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 shaft by hand
to assure seal and impeller rotate freely approx. every 30
days.
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 1. 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.
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.
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. Rough up area
covered by the baseplate for good grout bond.
CAUTION! - Remove and lock out power to driver.
4
3. 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.
ANGULAR ALIGNMENT
Insert an inside micrometer between the hub faces at 90°
intervals or rotate one hub 360° while taking readings from
the other hub. By means of thin metal shims, adjust the
driver until the faces are parallel (See Figure 3).
After each change it is necessary to recheck both parallel
and angular alignment as adjustment in one direction may
disturb adjustments made in another direction.
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.
4. FIELD ALIGNMENT
Figure 3060 Series units are normally furnished with a
spacer coupling to allow for servicing the pump rotating
assembly without removal of the pump casing, piping or
driver from the baseplate.
When the units are lined up cold, it is necessary to make
allowance for the vertical rise of the driver caused by any
heating when in operation.
After baseplate has been leveled and bolted to the
foundation, the shafts of pump and driver must be
realigned as misalignment may cause premature failure of
the pump and driver bearings.
When the preliminary alignment has been completed the
foundation bolts should be tightened evenly but not too
firmly. Before replacing coupling segment connect piping
to pump flanges and check motor rotation.
Remove the spacer segment from the coupling, see
manufactures instructions and check for parallel and
angular alignment as follows:
NOTE: Parallel and angular alignment must be checked
again after piping is cinnected to the pump and any
misalignment corrected. The coupling spacer segment can
then be reinstalled in the coupling.
WARNING - Coupling guards must be used to
avoid serious injury to operating personnel.
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.
Figure 2
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.
PARALLEL ALIGNMENT
Place a 6” scale or straight edge across the flanges of the
coupling hubs, keeping the scale parallel with the shaft,
check 4 points, 90° apart. By means of thin metal shims,
adjust the driver until the shafts are parallel (see Figure 2).
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.
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.
Figure 3
5
Figure 4
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.
HIGH TEMPERATURE FRAME
Connect cooling liquid to the pipe tap in the side of the
frame at the coupling end; 3/8” on Fig. 3062, 1/2” on Fig.
3065 and 3066, and outlet pipe on the opposite side. The
pipe tap in the bottom is for drain or temperature sensing
device.
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.
Cooling liquid must flow slowly and constantly, at the
required rate, to provide adequate cooling.
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.
9. LUBRICATION
a. Oil Lubricated Bearings - Pumps furnished with oil
lubricated bearings are shipped WITHOUT oil in the
frame (19). To fill the oil reservoir in the frame:
1. Install the Trico Opto-Matic constant level oiler
(77) on the frame as shown with the moveable
oiler body at its lowest position. Unscrew the
plastic bottle from the oiler and remove breather
(235) from the frame (19).
Fill bottle of the oiler and screw it onto the lower
reservoir. Several fillings of the bottle will be
required before the oil level in the bearing
reservoir is equal to the level for which the
oiler is adjusted. NEVER FILL FRAME
RESERVOIR THRU LOWER RESERVOIR
OF THE OILER. See LUBRICATION, Section D,
for recommended lubricants. When proper oil
level is obtained, refill and replace the plastic
bottle on the oiler, also replace the breather (235)
in the top of the frame.
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.
8. COOLING
If pumps are fitted for high temperature application with
cooling of the packing box cover (11) and frame (19).
Connect water lines to the packing box cover and frame for
cooling.
JACKETED PACKING BOX COVER
Connect cooling liquid piping to the lower (inlet) tap and
exit through the upper tap; 3/8” on Fig. 3062, 1/2” on Fig.
3065, 1/2” on Fig. 3066. The 1/2” tap in the top of the
jacket is for venting air before start-up. The 1/2” tap in the
bottom of the jacket is for drain.
b. Grease Lubricated Bearings - Grease lubricated
bearings are prelubricated at the factory before
shipment. See LUBRICATION, Section D, for
recommended lubricants.
6
c. Packing Box Cover - The pump may be furnished
with packing or mechanical shaft seal as ordered.
Packing must be continuously lubricated by suitable
grease through grease fitting or with compatible
liquid through tapping opening provided, from the
casing (1) or from outside source.
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.
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.
Mechanical shaft seals must be lubricated depending
on type of seal furnished. See LUBRICATION,
Section D, for recommended lubrication.
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.
d. Other Lubrication - For proper lubrication of
driver bearings and shaft couplings, See
manufactures instructions.
C - OPERATION
The following important items should be checked as pump
is started and placed in operation.
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 ptessed 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.
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
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 4. If correction
is necessary, it may be accomplished by the addition or
removal of shims from under the motor mounting feet.
Only after these items have been checked should the
pump be started.
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. The discharge gate vale should be
closed during priming. Be sure the mechanical seal and
power frame are supplied with the proper lubrication.
See LUBRICATION.
D. MAINTENANCE
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.
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.
7
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 the
constant level oiler, See Section B, item 9.
DOUBLE SEAL: On double seal applications, the seal
chamber must be filled with clear, compatible lubricating
liquid under pressure. The liquid may be from an outside
source or may be from the pump discharge passing
through a filter and/or heat exchanger when necessary.
Pressure on the box must be 15 to 25 psi higher than
suction pressure. The liquid must circulate through the
outlet and a restriction must be placed in the outlet to
assure pressure on the seal chamber.
Subsequent lubrication depends on operating conditions.
Periodic inspection of bearing lubrication is necessary and
additional grease or oil should be added as required.
If pressurized liquid is not available, Shell Alvania EPRO
#71030 grease may be used with pressurized grease cup
in limited applications.
CAUTION: DO NOT over grease bearings or
add excess oil
3. IMPELER ADJUSTMENT
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.
The following lubricants are recommended at the operating
temperature indicated:
POWER FRAME
Oil lubricated Bearings:
0°F - 150°F, - S.A.E. #10 Wt. Non-detergent oil
150°F - 250°F, - S.A.E. #20 Wt. Non-detergent oil
250ºF - 350ºF - Dow Corning 4-3600
To adjust impeller clearance:
a. Disconnect power supply to the driver.
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. Alternate tightening the jack screws (286) until they
are finger tight against the end face of the frame
(19), then loosen cap screws (213).
Grease Lubricated Bearings:
-100ºF - 40ºF - Supermil M-125
40ºF - 250ºF - Shell Dolium R or Chevron SRI #2
250ºF - 350ºF - Supermill ASU M-100
Water Cooled Power Frame is recommended for
temperatures above 350ºF.
PACKING BOX COVER
With Packing - Shell Alvania #71012 Grease
Jacketed Packing Box Cover is recommended for
temperatures above 250ºF.
NOTE: The face of the bearing housing flange (33) must
be parallel with the end face of the frame (19) during this
adjustment and at the final adjustment. This space should
be checked at 90º increments using blocks or suitable
gauges. The space should be approximately 5/15” on Fig.
3062 and 3065 frames and approximately 3/8” on Fig.
3066 frame.
Driver and Coupling:
See manufacture’s recommendations.
PACKING BOX: Packing must be continuously lubricated.
Packed pumps are normally furnished less an external
recirculation line. When operating with suction lift and
clean liquid, recirculation from the pump discharge to the
packing box (or suitable grease) may be used. When
lubrication is supplied from an outside source, it should be
cool, clear water, recommended grease, or a compatible
lubricating fluid.
d. Alternate tightening the jack screws (286) as follows:
For ductile iron pumps - an additional 1/4 turn
(1 hex) to obtain .006” to .008” clearance between
the impeller vanes and the casing.
For alloy pumps - an additional 1/2 turn (2 hex) to
obtain .016” to .020” clearance between the impeller
vanes and the casing. This clearance may be
measured with feeler gauge through suction inlet
of the casing or with the impeller against the casing,
use two dial indicators against the bearing cover
(37) to set the impeller clearance.
SINGLE SEAL: Pumps with single seals are normally
furnished with an external recirculation line. A portion of
the liquid being pumped is recirculated from the casing
through the seal chamber to serve as a lubricant anf
coolant.
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.
An alternate method is to supply a cool, compatible
lubricating liquid from an outside source to the seal
chamber at a pressure of 15 to 25 psi higher than suction
pressure.
f.
8
Place pump in operation and check the power
required with a watt-meter to be certain the impeller
does not rub the casing.
5. DISASSEMBLY
Due to “back pull-out” construction of these pumps, the
frame (19) and rotating assembly may be removed from
the unit for inspection or service without removing the
casing (1) or the driver from the baseplate or piping to the
casing.
4. PACKING BOX CARE
Before installing new packing, clean the packing box and
inspect parts for wear. If shaft sleeve (14) or pump shaft
(6) is worn it should be replaced as packing will not seal
against a worn surface.
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.
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.
a. Disconnect and remove all cooling or lubricating
piping from the pump.
b. Remove spacer segment from flexible shaft
coupling per manufacturer’s instructions.
c. Remove cap screws (277) from frame foot (274)
and casing cap screws (212) or nuts (249). Remove
frame (19) assembly from casing and frame foot.
Remove casing gasket (73).
d. Unscrew impeller (2) by turning counter clockwise
while holding the shaft at the coupling end with a
wrench. Remove shaft gasket (38).
e. Remove hex nuts (210) and gland clips (206) and
remove split gland (17) when pump is fitted with
packing (13). If pump has mechanical shaft seal
(89) remove hex nuts (210) and carefully slide seal
gland (251) with seal seat away from packing box
cover (11).
f. Remove the packing box cover from frame (19).
Packing (13) and lantern (29) may now be removed.
Figure 5
Die molded packing rings are preferable. Twist rings
sidways when installing. DO NOT pull rings straight out
over the shaft.
Insert two new rings of packing and tamp in place. Stagger
joints to minimize leakage. Insert the lantern ring (29),
includes two half rings, then add three more rings behind
the lantern ring, staggering the joints. Replace gland (17)
and tighten nuts (210) to seat packing and rotate pump
shaft (6) several times, then loosen nuts to “finger tight” for
pump start-up. Be sure that the lantern ring is positioned to
receive lubrication through inlet.
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.
If pump includes single mechanical shaft seal (89) scribe
a mark at the seal retainer (230) or spring retainer on the
shaft sleeve (14) or shaft to aid in reassembly. Remove
seal gland gasket (259).
If packing replacement becomes frequent:
a. Check pump bearing for excessive wear causing
shaft run-out.
b. Check packing for proper grade. Also check
whether special packing is used. All iron pumps
include Graphite impregnated non-asbestos
packing; stainless steel pumps include Teflon
impregnated white non-asbestos packing.
c. Check shaft sleeve for excessive wear or scoring.
d. Check for crystallization of the solution and for
embedded abrasives in the packing. Method of
packing lubrication may not be satisfactory.
e. Check recirculating line, if used as well as reievant
fittings, for partial or full blockage.
For care of mechanical shaft seals, see LUBRICATION.
g. Remove shaft sleeve (14) (slide fit) and key (279)
from the pump shaft (6). Seal rotating assembly
(89B) and retainer (230) (when furnished) will be
removed with the shaft sleeve.
h. Remove seal gland with seal and deflector (40)
from pump shaft.
