INSTALLATION

PUMP LOCATION

6

Locate the pump so there is sufficient room for
inspection, maintenance and service. If the use of
a hoist or tackle is needed, allow ample head
room.

WARNING: Falling Objects Hazard
Eyebolts or lifting lugs, if provided, are for

lifting only the components to which they are
attached. Failure to follow these instructions could
result in serious personal injury or death, or
property damage.

If lifting base pump is required, use a nylon string,
chain, or wire rope, hitch around both bearing
supports. If lifting of the entire pump is required,
do so with slings placed under the base rails as
shown.

Care must be taken to size equipment for
unbalanced loads which may exist if the motor is
not mounted on the base at the time of lifting.
Motor may or may not be mounted at the factory.

Pump, base, and driver assemblies where the
base length exceeds 100 inches may not be safe
to lift as a complete assembly. Damage to the
baseplate may occur. If the driver has been
mounted on the baseplate at the factory, it is safe
to lift the entire assembly. If the driver has not
been mounted at the factory, and the overall
baseplate length exceeds 100 inches, do not lift
the entire assembly consisting of pump, base, and
driver. Instead, lift the pump and baseplate to its
final location without the driver. Then mount the
driver.

The best pump location for sound and vibration
absorption is on a concrete floor with subsoil
underneath. If the pump location is overhead,
special precautions should be undertaken to
reduce possible sound transmission. Consult a
sound specialist.

FIGURE 4

If the pump is not on a closed system, it should be
placed as near as possible to the source of the
liquid supply, and located to permit installation with
the fewest number of bends or elbows in the
suction pipe.

The installation must be evaluated to determine
that the Net Positive Suction Head Available
(NPSHA) meets or exceeds the Net Positive
Suction Head Required (NPSHR), as stated by the
pump performance curve. See page 14 for more
details on proper suction piping installation.

RECEIVING PUMP
Check pump for shortages and damage
immediately upon arrival. (An absolute must.)
Prompt reporting to the carrier’s agent with
notations made on the freight bill, will expedite
satisfactory adjustment by the carrier.

Pumps and drivers normally are shipped from the
factory mounted and painted with primer and one
finish coat. Couplings may be either completely
assembled or have the coupling hubs mounted on
the shafts and the connecting members removed.
When the connecting members are removed, they
will be packaged in a separate container and
shipped with the pump or attached to the base
plate.

Shafts are in alignment when the unit is shipped;
however, due to shipping, the pumps may arrive
mis-aligned and, therefore, alignment must be
established during installation. AC Fire Pump
Systems has determined that proper and correct
alignment can only be made by accepted erection
practices. Refer to the following paragraphs on
