3 Product Description
3.1 General
This instruction manual is intended to assist those involved with the installation, operation and mainte-
nance 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, how-
ever, 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 provi-
sions of this instruction manual. This pump is not to be operated at speeds, working pressures, dis-
charge pressures, or temperatures, nor used on liquids other than stated in the original order acknowl-
edgment without written permission of Gould’s Pumps.
3.1.1 Pump Description
The AF pump generates flow by the thrust or lift action of the rotating axial vanes of the impeller. It pro-
vides 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:
Table 2: Pump Description
Power End Inboard Bearing Outboard Bearing
LMR Spherical roller Spherical thrust/spacer/Spherical roll-
er
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.Ad-
justing 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 cy-
lindrical bore with flush ports and gland face for packing. The standard packed box includes (5) rings of
3 Product Description
12 Model AF (42"/1200mm/54"/60"/66") LM/LMR Bearings Installation, Operation, and Maintenance Manual

packing and (2) lantern rings to seal the shaft area. (2) flush ports are provided for lubrication. The inner-
most flush port is used with process flow and the outermost port for water flush. A special alternate pack-
ing 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.
Shaft Sleeve
If packing is specified, a replaceable wear sleeve is provided with the power end. The sleeve is keyed to
prevent rotation. The stuffing box can also be modified to accept a mechanical seal if required.
Impeller
The impeller is cast with (4) fixed vanes at 0 or +5 degrees, CW or CCW rotation, and top or end suction.
The impeller bore is stepped for easy assembly to the shaft. It is held in place with a key, shaft washer,
and bolts. It has a cover plate and o-rings to prevent corrosion and allow for easy impeller replacement.
The impeller is dynamically balanced (two plane) per ISO 1940 to a quality grade G-16.
Shaft
The shaft is cantilevered into the elbow to eliminate the need for internal bearings. It is sized for minimal
deflection, high critical speed, and extreme corrosion resistance. The shafts are stepped for easy assem-
bly with the impeller. The shaft comes with a replaceable sleeve when used with stuffing boxes.
Bearings
The inboard radial bearing absorbs shaft radial loads and aligns the pump shaft. It is a spherical roller
bearing. The outboard thrust bearing absorbs impeller thrust loads and comes as either back-to-back an-
gular contacts or a single taper roller bearing, depending on pump size. Lubrication is by flood oil.
Oil Cooling (Optional)
An oil-cooling coil is available on all sizes, it is installed in the bottom of the bearing housing and circu-
lates water to cool the oil bath. Generally, it is used when process temperatures cause excessive heat
build up in the bearing housing and/or bearings.
Configurations and Drives
The 42", 1200mm, 54", 60", and 66" pumps are usually gear driven and come on a subbase as standard.
They can also be pipe mounted with a drive shaft to a motor on a separate subbase.
3.2 Nameplate information
Important information for ordering
Every pump has nameplates that provide information about the pump. The nameplates are located on
the bearing housing.

4 Installation
4.1 Preinstallation
AF units are usually shipped completely assembled. Check all bolts and nuts on the entire unit and make
sure they are securely tightened.
If necessary install and adjust drive components per manufacturer’s recommendations
Equipment that will operate in a potentially explosive environment must be installed in accordance
with the following instructions.
All equipment being installed must be properly grounded to prevent unexpected static electric dis-
charge. If not, a static electric discharge may occur when the pump is drained and disassembled for
maintenance purposes.
4.1.1 Foundation Requirements
AF pump shall be located in a clean, dry area free from flooding. The area should provide adequate
space for operation, maintenance, inspection and repair, considering complete disassembly and handling
of equipment. The pump should have a supply of clean liquid for packing or mechanical seal lubrication.
The pump shall be positioned to provide the most efficient pipeline system.
The AF pumps covered by these instructions may be designed to hang in the piping system, furnished
with spring loaded sub-base bolts, or have a sub-base designed to be anchor bolted and grouted to the
foundation.
The foundation must be substantial enough to absorb any vibration and form a permanent, rigid support
for the pumping unit to the degree that there shall not be any adverse movement or settling over a long
period of time.
Foundations for anchor bolted and grouted sub-bases are typically concrete with anchor bolts cast in to
secure the pump.
The most commonly used foundation bolts are the sleeve-type.

4.1.2 Sub-base Leveling
Grouted Base
When the unit is received with the pump and driver mounted to the sub-base, it should be placed on the
foundation and the coupling halves or V-belts disconnected (see Figure titled Sub-base, top view). The
coupling should not be reconnected until all realignment operations have been completed. A recom-
mended coupling alignment procedure is included in the following sections.

1. The sub-base should be supported on rectangular metal blocks or on metal wedges having a slight
taper. There should be support blocks or wedges on both sides of each foundation bolt. A gap of
about 19mm | 3/4" to 38mm | 1-1/2" should be allowed between the sub-base and the foundation for
grouting, see Figure titled Sub-base, side view.
2. Adjust the metal supports or wedges until the shafts of the pump and driver and sub-base are level.
Check the coupling faces, as well as the suction and discharge flanges of the pump, for horizontal
and vertical position by means of a level. Check also for any internal rubbing in the pump. Correct, if
necessary, by adjusting the supports or wedges under the sub-base as required. In most cases, fac-
tory alignment will be regained by shimming under the sub-base alone. Provisions must be made to
support the discharge piping independently from the pump to prevent excessive loads and maintain
pump-driver alignment.
3. The sub-base should be level to within 3 mm | 0.125" over the length of the base and 1.5 mm |
0.0875" over the width of the base. Bases anchored with conventional foundation bolts use shims
on both sides of the anchor bolts to level the base. The bolts which secure the pump sub-base to
the foundation should be 3mm | 1/8" to 6mm | 1/4" less in diameter than the holes in the sub-base
(hole size is shown on the certified installation drawing).
4. Clean outside areas of sub-base that will contact grout. Do not use oil-based cleaners because
grout will not bond to it. Refer to grout manufacturer's instructions.
5. Build a dam around foundation and thoroughly wet the foundation.
