INSTALLATION
Install the pump as a free standing unit or with a guide rail
lift-out system.
Free-Standing Unit:
Install the pump on the floor of an open top basin. Install a
pipe union in the discharge piping, so that the pump can be
lifted out of the basin without interference.
Lift-out System
(see Assembly Steps, Page 4)
:
(See Figures 4 and 5 before assembling)
1.
Mount the base flange (See Step 1, Page 4) to the basin
floor.
2.
Thread the 2-1/2” (64 mm) dia. pipe section (Step 2) into
the base flange and tighten it.
3.
Install the stationary flange (Step 3) on the base pipe
and tighten the set screw to hold it.
4.
Install the connecting plumbing in the stationary flange
(Step 4).
5.
Thread the user supplied 1” (25 mm) dia. guide rails
(Step 5) into the stationary flange and tighten them.
6.
Mount the upper rail bracket on the angle bracket
(Step 6).
7.
Install the angle bracket and upper rail bracket assembly
in the tank or attach it to the basin lid as desired
(Step 7).
8
.
Install the basin lid now if the guide rail bracket is
mounted on it (Step
8
).
The stationary parts (all those parts mounted in the basin)
of the guide-rail lift-out system are now complete. Go on to
Step 9 to assemble the movable parts of the system. These
will mount on the pump discharge assembly.
Follow the
sequence below that applies to your pump model.
SG12 / SG13 Series:
9A.
SG12/SGC12/SG13/SGC13
Thread the 1-1/4x
8
-1/2” nipple
into the pump discharge and tighten it.
9B.
SG12/SGC12/SG13/SGC13
Install the movable guide rail
bracket over the
8
-1/4” nipple, then install one half of the
pipe union on top of the nipple and tighten it. Do not tight-
en the set screws in the guide rail bracket yet.
9C.
SG12/SGC12/SG13/SGC13
Clamp the ball check valve
upside down (that is, flange up) in a vise so that it can-
not turn (or fall) and thread one of the short nipples into
it. Install the unused union half on the short nipple and
tighten the assembly.
9D.
SG12/SGC12/SG13/SGC13
Turn the check valve
assembly over in the vise; clamp it so that the ball
chamber points to your right or your left. Install the other
short nipple in the discharge (hex) end of the check
valve. Add the discharge pipe bracket over the nipple
and then thread the movable flange onto the nipple.
When tight, the movable flange should point directly
away from you (that is, the check valve and the flange
should be at right angles to each other). Install two
O-Rings on the movable flange (see Step 9, Page 4).
10.
SG12/SGC12/SG13/SGC13
Remove the check valve
assembly from the vise and turn it over; connect the
union and tighten it with the movable flange pointing
directly away from the pump. The ball check should point
to one side or the other while the movable bracket points
away from the pump. Thread the eyebolt through the dis-
charge pipe bracket into the tapped hole provided in the
top of the pump.
11.
SG12/SGC12/SG13/SGC13
Thread the locking rail into
the movable flange; mount the locking bracket and tight-
en.
The movable parts of the SG12/SGC12/SG13/SGC13
system are now complete. You are ready to rig lifting gear
and lower the pump into the basin. Skip to Step 12.
SG20 Series:
9A.
SGC20
Thread one of the short nipples into the pump
discharge; add a union half and tighten the assembly.
9B.
SGC20
Clamp the ball check valve in a vise; thread the
2x6” nipple into the inlet side. Slide the guide rail bracket
(also upside down) on to the nipple and thread the other
union half over the free end of the nipple. Tighten.
9C.
SGC20
Turn the assembly over in the vise and thread
the other short nipple onto the discharge side of the ball
check valve. Add the discharge pipe bracket and the
movable flange to this nipple and tighten the assembly.
When tight, the ball check should point to one side or
the other and the movable flange should point directly
away from you (that is, the check valve and the flange
should be at right angles to each other). Install two
O-Rings on the movable flange (see Step 9, Page 4).
10.
SGC20
Mount the ball check valve/discharge flange
assembly on the pump with the movable flange pointing
directly away from the pump. Tighten the union and
thread the eyebolt through the discharge pipe bracket
into the the threaded hole provided in the top of the
pump.
11.
SGC20
Thread the locking rail into the movable flange;
mount the locking bracket and tighten.
The movable parts of the SGC20 system are now complete.
You are ready to rig lifting gear and lower the pump into the
basin.
12. Lift the pump assembly; slide the guide rail bracket and
the movable flange over the guide rails at the top and
lower the pump into the basin until it bottoms on the sta-
tionary flange. Raise the pump 1/
8
” and tighten the
guide rail bracket set screws.
13. Slide the locking bracket over the guide rails and locking
rail, then tighten all three set screws.
14.
To remove the pump
, loosen the guide rail set screws
in the locking bracket and hoist the pump out of the
basin.
CONTROLS
Risk of electric shock. Ground pump and
motor before connecting controls or power supply.
Adhere to local electrical codes governing pump and control
installations.
Install simplex or duplex control panel for proper pump oper-
ation. A full range of controls and switches is listed in our
catalog.
If a Sta-Rite control panel is not used, install a control panel
with circuit breaker or fused disconnect as required by local
code. Use magnetic starters with ambient compensated
overload protection. Three phase units require three line pro-
tection; single phase units require only one line protection.
Inadequate protection voids warranty.
SGC12/SGC13
Series pumps are equipped with an on-
winding thermostat (to protect the pump from overheating)
and seal leak detection probe (to monitor seal plate and
motor housing for the presence of water).
