INSTALLATION

INCLUDES
Check pump for shortage and damage immediately upon
arrival. Note damage or shortage on freight bill (bill of
lading); immediately file claim with carrier.
EXTERIOR
— Pay particular attention to conduit box,
external hardware and accessories. Touch up abrasions
or scratches with approved paint.
INTERNAL
— If extensive or serious external damage
is noted, if impeller is damaged (look in ports), or if shaft
binds or sticks, disassemble as required to permit
internal inspection.
HANDLING
Handle with care. Dropping or jarring can seriously
damage engine or break pump parts. Rig a double sling
under engine frame and pump casing. Do not use a sling
through pump engine or around suction and discharge
flanges.
Engine manufacturers do not recommend transporting
engine with fuel in tank or with fuel shut-off valve open.
(Refer to engine manufacturers manual.)
INSTALLATION
Location
— Pump location should provide the
following:
1. Install as close to suction supply as possible.
2. Shortest and most direct suction pipe practical.
Suction lift must not exceed limit for pump. NPSH
available must equal or exceed pump requirement.
3. Room for inspection and maintenance.
4. Adequate ventilation - exhaust gases contain carbon
monoxide - an odorless and deadly poisonous gas.
6. If outdoors, protection from the elements, freezing
and water damage due to flooding.

Piping
— Suction and discharge gauges are useful to
check pump operation and are excellent trouble
indicators. Install gauges in the lines if pump ports do
not have gauge taps. Observe these precautions when
installing piping:
1. Support close to, but independently
of pump.
2. Use the next larger pump size for suction
and discharge.
3. Keep as straight as possible. Avoid bends
and fittings.
4. Remove burrs, sharp edges, ream pipe cuts, and
make joints air-tight.
5. Don't spring pipe to make connections.
Strain must not be transmitted to pump.
6. Allow for pipe expansion with hot fluids;
expansion joints are not recommended.
Suction
— Size and install suction piping to keep
pressure loss at minimum and to provide correct NPSH
by observing the following:
1. The suction pipe should be equal in size or
preferably one size larger than the suction
connection of the pump. If pipe is larger than the
pump suction, an eccentric pipe reducer should be
used at the pump.
2. For hose applications, use reinforced type that will
not collapse under suction. Use thread sealer to
make sure all suction connections are airtight.
3. Attach a suction strainer (if required) to the end of
the suction hose. Be sure to keep the suction
hose submerged.
