A - GENERAL INFORMATION
TO THE PURCHASER:
Congratulations! You are the owner of one of the fi nest
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, fi le 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 effi cient
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.
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 b40 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.
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

B - INSTALLATION
Standard pump are completely assembled and carefully
adjusted at the factory before shipment.
1. Prior to installation of the unit remove the thread
protectors from the suction and discharge nozzles, also
check the following:
a. Turn pump shaft (6) several revolutions by hand to
be certain that it turns freely.
b. Check and tighten coupling set screws (211) which
may loosen during shipment.
2. Carefully lower the assembled unit into the tank or
through the hole in the support plate.
3. Bolt support head (71) to tank cover or support plate.
4. Connect discharge piping to casing discharge nozzle.
The weight of the discharge pipe and fi ttings must be
supported independently of the pump to eliminate any
strain on the pump casing (1).
5. Turn pump shaft (6) by hand to make sure that it
rotates freely after installing pump and connecting the
discharge
pipe.
6. Make temporary electrical connections and jog motor to
check rotation. Pump should rotate in a clockwise
direction when looking down upon the top of the motor.
7. Pump should operate smoothly. If pump vibrates, there
is a severe distortion of the pump as a result of
excessive installation strain on pump support plate or
discharge
pipe.
8. Make permanent electrical connections.
C - LUBRICATION
1. Pump shaft bearing (171) is lubricated by the liquid
being
pumped.
2. Motor bearings have been greased at factory. Follow
motor manufacturer’s recommendations as to the type
of grease and frequency of lubrication.
D - GENERAL REPAIRS
A. For inspection and repair of liquid end.
1. Disconnect electric service to motor and remove
wires from motor.
2. Disconnect discharge piping from pump.
3. Unscrew bolts from support head (71), then remove
complete pumping unit with motor to a work bench.
4. Unscrew cap screws (212) and remove casing (1)
and casing gasket (73). Place gasket in a bucket of
water to keep it pliable.
5. Check for wear on casing face (1) where impeller
might rub, also inspect impeller faces both front and
back for wear.
6. If impeller must be replaced, proceed as follows:
a. On 1”, 1½” or 2” pumps, unscrew impeller lock
nut (24) then unscrew impeller (2) turning it
counter-clockwise while holding shaft (6) with
wrench.
b. On 3” pumps, unscrew impeller lock nut (24)
while holding shaft (6) with wrench, then remove
impeller washer (270). Screw three 1/4” x 2” NC
capscrews into tapped holes in impeller shroud to
force impeller off of shaft. Remove key (32) from
shaft.
B. For inspection and replacement of shaft bearing and seal.
1. Dismantle liquid end as described in Section A.
2. Remove cap screws (219) and tap support head (71)
gently, knocking it loose from motor (228).
3. If the inside of shaft bearing (171) is more than .025”
larger than the shaft diameter (6), bearing should be
replaced.
4. Place support head (71) in an arbor press, and push
out shaft bearing (171).
5. Check seal (89) if worn, replace. The worn one will
have to be pressed out and new one pressed in.
