MOuNTING
1. Surfaces to which the pump mounts must be clean and flat.
2. Use SAE Grade 5 or better capscrews to mount pump.
3. The 4 mounting capscrews for the SG-04 and SG-05 pumps must have a minimum of ½
inch thread engagement, and must be torqued evenly to 12-15 ft-lbs.
4. The 2 mounting capscrews for the SG-07 pumps must have a minimum of ½ inch
thread engagement, and be evenly torqued to 50-55 ft-lbs.
5. Standard SG Series pumps are designed to be used with jaw type couplings that do not
induce axial thrust on the pump shaft. If an improper type of coupling is used, internal
damage may result.
6. Do not strike or press the pump drive coupling to install. Internal pump damage will
result. If the coupling does not slide onto the shaft, inspect the coupling, shaft and
key for nicks or burrs and remove.
7. If the pump is to be belt or gear driven, the overhung load option must be specified.
8. Once the pump has been mounted and the coupling installed, it is recommended to put
lube oil into the suction port and turn the pump by hand to make sure it turns freely.
Alignment
Check alignment after mounting.
1. If the unit has a flexible coupling, remove any coupling guards or covers and check
alignment of coupling halves. A straight edge (piece of key stock will work) across the
coupling must rest evenly on both rims at the top, bottom and sides. See Figure 3.
2. Make a final check on alignment after the piping is hooked up.

Piping/Hose
The cause of many pumping problems can be traced to the suction piping. It should always be
as large in diameter and as short in length as possible.
Before starting the layout and installation of your piping system, consider the following points:
1. Never use piping smaller than the pump port connections. Piping larger in diameter than
the port connection is sometimes required to reduce friction losses.
