PAGE B − 2 INSTALLATION
POSITIONING PUMP
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. Attach lifting equip-
ment to the lifting device fitted to the
pump. If chains or cable are wrapped
around the pump to lift it, make certain
that they are positioned so as not to
damage the pump, and so that the load
will be balanced. The bail is intended for
use in lifting the pump assembly only.
Suction and discharge hoses and pip-
ing must be removed from the pump be-
fore lifting.
Lifting
Use lifting and moving equipment with a capacity
of at least 5 times the weight of the pump, not in-
cluding the weight of any customer installed ac-
cessories. Customer-installed equipment such as
suction and discharge piping must be removed
before attempting to lift. Contact the factory or the
Pump Specification Data Sheet for the approxi-
mate weight of your pump.
The pump assembly can be seriously
damaged if the chains or cables used to lift
and move the unit are improperly wrapped
around the pump.
Mounting
Locate the pump in an accessible place as close as
practical to the liquid being pumped. Level mount-
ing is essential for proper operation. The pump
may have to be supported or shimmed to provide
for level operation and eliminate vibration.
For engine driven units, the pump must be posi-
tioned as level as possible to ensure sufficient lubri-
cation and fuel supply to the engine.
If the pump has been mounted on a moveable
base, make certain the base is stationary by setting
the brake and blocking the wheels before attempt-
ing to operate the pump.
If the pump has been mounted on a mov-
able base, do not attempt to operate the
pump unless the unit is level. Be sure
the leveling stands are positioned on a
solid surface, and the wheels are
chocked.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by in-
creased suction lift, discharge elevation, and fric-
tion losses. See the Performance Curve in the Parts
List Manual to be sure your overall application al-
lows pump to operate within the safe operation
range.
Materials
Either pipe or hose maybe used for suction and
discharge lines; however, the materials must be
compatible with the liquid being pumped. If hose is
used in suction lines, it must be the rigid-wall, rein-
forced type to prevent collapse under suction. Us-
ing piping couplings in suction lines is not recom-
mended.
Line Configuration
Keep suction and discharge lines as straight as
possible to minimize friction losses. Make mini-
mum use of elbows and fittings, which substan-
tially increase friction loss. If elbows are necessary,
use the long-radius type to minimize friction loss.
Connections to Pump
Before tightening a connecting flange, align it ex-
actly with the pump port. Never pull a pipe line into
place by tightening the flange bolts and/or cou-
plings.
Lines near the pump must be independently sup-
ported to avoid strain on the pump which could
