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.
