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 - BEFORE YOU BEGIN

Motor driven pumps are carefully aligned on sub-base 
before shipment. However, after they are placed upon the 
foundation and sub-base is bolted down, the alignment 
must be rechecked and in MOST CASES it will be found 
necessary to carefully realign the unit. Quite often a noisy 
pump is due to pump and motor not being properly aligned. 
IN SUCH CASES WE DISCLAIM ALL RESPONSIBILITY 
FOR PROPER WORKING OF PUMP.

C - INSTALLATION

1.  A good rigid foundation must be provided for pump 
 base.

2.  Place pumping unit on foundation with bolts, of the 
 

proper size, imbedded in the concrete. A pipe sleeve, 

 

about 2½” diameters larger than the bolt, should be 

 

used to allow for fi nal positioning of the bolts. See 

 

Figure 1. Level sub-base, to give a space of about 3/4”

 

for grouting, using rectangular metal blocks and shims,

 

or wedges having a small taper as shown in Figure 2.

3.  Align the pump and motor shafts at the fl exible coupling.
 

Hold a straight edge on the top of the coupling so that it 

 

extends over both halves. Straight edge should rest 

 

evenly across both rims of the coupling halves when the

 

straight edge is placed on the top, sides and bottom with

 

no light showing between the straight edge and rim of 

 

the coupling. Also check vertical alignment of the 

 

coupling faces with a thickness gauge. Faces must be 

 

parallel and spaced about 1/8” apart when the motor 

 

rotor is at its extreme position towards the pump. This 

 

safe guards the pump shaft being crowded endwise by 

 

the motor shaft end play. By proper adjustment of metal 

 

shims under pump or motor, both halves of the fl exible 

 

coupling can be brought into alignment See Figure 3.
