2. Locate pump as near liquid source as possible (below
level of liquid for automatic operation).
3. Protect from freezing or floods.
4. Allow adequate space for servicing and ventilation.
5. For close-coupled pumps, the foundation must be flat
and substantial to eliminate strain when tightening
bolts. Use rubber mounts to minimize noise and
vibration. Tighten motor hold-down bolts before
connecting piping to pump.
6. All piping must be supported independently of the pump,
and must “line-up” naturally. Never draw piping into place
by forcing the pump suction and discharge connections!
7. Angular alignment of the flanges can best be accom-
plished using calipers at bolt locations (See Figure 2).
Hazardous voltage
can shock, burn or
cause death.
3. Motors must be wired for proper voltage (check name-
plate). Wire size must limit maximum voltage drop to

• If realignment is necessary, always move the motor. Shim
as required.
• Parallel misalignment, shafts with axis parallel but not
concentric. Place dial indicator on one hub and rotate this
hub 360° while taking readings on the outside diameter of
the other hub. Parallel alignment is achieved when reading is
0.005" (0.127 mm) TIR, or less.
• Angular misalignment, shaft with axis concentric but not
parallel. Place dial indicator on one hub and rotate this hub
360° while taking readings on the face of the other hub.
Angular alignment is achieved when reading is 0.005"
(0.127 mm) TIR, or less.
• Final alignment is achieved when parallel and angular
requirements are satisfied with motor hold-down bolts tight.
NOTICE: ALWAYS RECHECK BOTH
ALIGNMENTS AFTER MAKING ANY
MECHANICAL ADJUSTMENTS.
4. Piping
• Piping should be no smaller than pump’s discharge and
suction connections and kept as short as possible, avoiding unnecessary fittings to minimize friction losses. See
Table 1.
• All piping MUST be independently supported and
MUST NOT place any piping loads on the pump.
NOTICE: DO NOT FORCE PIPING INTO PLACE
AT PUMP SUCTION AND DISCHARGE
CONNECTIONS.
• All pipe joints MUST be airtight.
SUCTION PIPING
1. Low static lift and short, direct suction piping is
desired. For suction lift over 15 feet, consult pump
performance curve for Net Positive Suction Head
Required.
2. Suction pipe size must be at least equal to suction
connection of pump.
3. If larger pipe is used, an eccentric pipe reducer (with
straight side up) must be used at the pump.

4. Installation with pump below source of supply:
4.1. Install isolation valve in piping for inspection and
maintenance.
4.2. Do not use suction isolation valve to throttle pump!
5. Installation with pump above source of supply:
5.1. To avoid air pockets, no part of piping should be
higher than pump suction connection. Slope
piping upwards from liquid source.
5.2. All joints must be airtight.
5.3. Foot valve to be used only if necessary for priming,
or to hold prime on intermittent service.
5.4. Suction strainer open area must be at least triple
the pipe area.
6. Size of inlet from liquid source, and minimum submer-
gence over inlet, must be sufficient to prevent air
entering pump.
DISCHARGE PIPING
1. Arrangement must include a check valve located
between a gate valve and the pump. The gate valve is
for regulation of capacity, or inspection of pump or
check valve.
2. If reducer is required, place between check valve and pump.
5. Wiring and Grounding
WARNING
Hazardous voltage
