GENERAL
This instruction manual is intended to assist those
involved with the installation, operation and
maintenance of Gould’s pumps. It is recommended
that this manual be thoroughly reviewed prior to
installing or performing any work on the pump or
motor.
The design, material and workmanship incorporated
into the construction of Gould’s pumps makes them
capable of giving long, trouble-free service. The life
and satisfactory service of any mechanical unit,
however, are enhanced and extended by periodic
inspection and careful maintenance. Keep this
instruction manual handy for reference. Further
information can be obtained by contacting Gould’s
Pumps, Ashland Operations, East Centre St., Ashland,
PA 17921 or your local representative.
Gould’s Pumps will not be liable for any damages or
delay caused by failure to comply with the provisions of
this instruction manual. This pump is not to be
operated at speeds, working pressures, discharge
pressures, or temperatures, nor used on liquids other
than stated in the original order acknowledgment
without written permission of Gould’s Pumps.
PUMP DESCRIPTION
The AF pump generates flow by the thrust or lift
action of the rotating axial vanes of the impeller. It
provides high flow rates and low heads which are
ideal for re-circulation, evaporator, and generator
cooling systems. The AF utilizes an elbow to direct
the flow through the suction and out the discharge
end of the pump. The pump accommodates top or
end suction configurations using either the LMR or
LM bearing arrangement. The LMR is for top
suction and the LM is for end suction.
Arrangements are as follows:
Power Inboard
Outboard
End Bearing Bearing
LMR Spherical roller Spherical thrust/spacer/Spherical
roller
LM Spherical roller Spherical roller/spacer/Spherical
thrust
Elbow – AF elbows are fabricated with 150# flat
face suction and discharge flanges. They come
with fabricated feet for mounting to a sub-base or
without feet to be mounted directly in the piping.
The elbows have a built in stuffing box and a rear
flange for mounting the power end to the elbow.
There are also adjusting lugs for aligning the shaft
to the stuffing box.
Casing – The AF comes with a casing or spool piece to
simplify impeller installation and alignment. The casing
bolts to the elbow and shrouds the impeller. It has a gasket
or o-ring seal between it and the elbow. Adjusting lugs on
the elbow center the casing relative to the impeller.
Power End - The power end is made up of the bearing
housing, bearings, locknuts, lock washers, labyrinth oil
seals, shaft, shaft sleeve (w/packing), oil slinger, keys,
shaft, and shaft washer.
Stuffing Box – The stuffing box is integral with the elbow
and provides a mounting surface for a mechanical seal or
cylindrical bore with flush ports and gland face for packing.
The standard packed box includes (5) rings of packing and
(2) lantern rings to seal the shaft area. (2) flush ports are
provided for lubrication. The innermost flush port is used
with process flow and the outermost port for water flush. A
special alternate packing arrangement is available that
includes a throat bushing and additional ring of packing
near the gland (see the attached addendum). A gland is
used for packing adjustment.
