INSTALLATION

PREINSTALLATION INSPECTION

The pump assembly was inspected and tested be-
fore shipment from the factory. Before installation,
inspect the pump for damage which may have oc-
curred during shipment. Check as follows:

a. Inspect the pump and engine for cracks,

dents, damaged threads, and other obvious
damage.

b. Check for and tighten loose attaching hard-

ware. Since gaskets tend to shrink after dry-
ing, check for loose hardware at mating sur-
faces.

c. Carefully read all tags, decals, and markings

on the pump assembly, and perform all duties
indicated.

d. Check levels and lubricate as necessary. Re-

fer to LUBRICATION in the MAINTENANCE
AND REPAIR section of this manual and per-
form duties as instructed.

e. If the pump and

engine have been stored for

more than 12 months, some of the compo-
nents or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump serv-
ice.

POSITIONING PUMP

Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. Suction and dis-
charge hoses and piping must be re-
moved from the pump before lifting.

Lifting

Pump unit weights will vary depending on the
mounting and drive provided. Check the shipping

tag on the unit packaging for the actual weight, and
use lifting equipment with appropriate capacity.
Drain the pump and remove all customer-installed
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.

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 or to eliminate vibra-
tion.

If the pump has been mounted on a moveable
base, make certain the base is stationary by block-
ing the wheels before attempting to operate the
pump.

To ensure sufficient lubrication and fuel supply to
the engine, do not position the pump and engine
more than 15

_ off horizontal for continuous opera-

tion. The pump and engine may be positioned up
to 30

_ off horizontal for intermittent operation

only; however, the engine manufacturer should be
consulted for continuous operation at angles
greater than 15

_.

SUCTION AND DISCHARGE PIPING

Pump performance is adversely effected by in-
creased suction lift, discharge elevation, and fric-
tion losses. See the performance curve on Page
E-1 to be sure your overall application allows 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.
