1.0 Important Safety Instructions
WARNING: Many accidents occur every year through careless use of mechanical equipment. You can avoid
hazards associated with high pressure equipment by always following the safety precautions listed below.
SHUT DOWN OR DISENGAGE the pump and all accessory equipment before attempting any type of service.
Failure to do this could cause electrical shock or injury from moving pump parts or components under high
pressure. Always adhere to “Lock Out” and “Tag Out” procedures. For mobile equipment, be sure engines and
hydraulics cannot be accidentally started.
BLEED OFF ALL PRESSURE to the pump and piping before performing any maintenance on the pump. Failure to
do so may spray water or chemicals at high pressure or high temperature onto service personnel.
NEVER OPERATE THE PUMP WITHOUT A PRESSURE RELIEF VALVE, rupture disc, or other type of properly sized
over pressure safety device installed.
ALWAYS USE A PRESSURE GAUGE when operating the pump. The pressure must never exceed the maximum
pressure rating of the pump or damage may occur. This damage can cause leakage or structural damage
resulting in injury to personnel.
ENSURE THAT NO VALVES ARE PLACED BETWEEN THE PUMP AND PRESSURE RELIEF VALVE. If the pump is
started with a closed or restricted valve in line before the pressure relief valve, the pump may exceed the rated
or designed pressure limits and rupture causing injury to personnel.
USE SHIELDS OR COVERS AROUND PUMPS when pumping hot water, chemicals, or other hazardous liquids.
This precaution can prevent the exposure of service personnel to these fluids should leakage occur.
ALWAYS USE GUARDS on all belt drives, couplings, and shafts. Guards can prevent personnel from becoming
entangled and injured by rotating and reciprocating parts.
USE EXTREME CAUTION WITH SOLVENTS used to clean or degrease equipment. Most solvents are highly
flammable and toxic. Observe all safety instructions on packaging.
FOLLOW NORMAL ENVIRONMENTAL GUIDELINES WHEN fluids, lubricants, or solvents are disposed of or
spilled.
NEVER MODIFY THE PUMP to perform beyond its rated specifications without proper authorization in writing
from AMERICAN MFG COMPANY.

3.0 Storage Instructions
Proper storage of your American Mfg Company pump will ensure that it is ready for service when needed. Follow
the guidelines below that fit the requirements of your application.
American Mfg Company pumps come from the factory without crankcase oil and are prepared for storage
periods of up to six (6) months in proper environmental conditions. Indoor storage in a dry, temperature-
controlled location is always recommended. If pumps are to be stored short term (less than six (6) months) in a
severe environment, they should be prepared using the procedures outlined in the “Short Term Storage for Severe
Environments” section 3.2 below. Remember that any fluid that poses an environmental hazard or is toxic must be
handled and disposed of properly.
3.1 Short Term Storage
If the pump is stored in an indoor, temperature controlled environment for less than six (6) months, no special
steps are required to prepare it for storage. As a general rule for pumps in corrosive fluid applications, the fluid
end should be drained, flushed with water or other non-corrosive cleanser and compressed air used to blow dry
whenever idle.
3.2 Short Term Storage for Severe Environments
If the pump has been in service, drain any fluid from pump fluid end, flush the fluid end with water to clean out any
of the remaining pumpage and blow dry with compressed air. Pour 1/4 to 1/2 cup of internal rust inhibitor oil
described in Table 2 (see Recommended Lubricant Chart, Section 6.2), into the suction and discharge ports of fluid
end, and then install pipe plugs in openings. Drain the power end (crankcase) oil and remove the oil fill cap (or
plug). Pour ½ to 1 cup of internal rust inhibitor oil described in Table 2 into the oil fill hole and then install the filler
cap. Coat all exposed, unpainted metal surfaces (for example, Driveshaft) with preservative oil. Replace the oil fill
cap, and then cover the entire pump with a weather resistant covering such as a canvas or plastic tarp.

3.3 Returning a Stored Pump to Operation
Before operating a pump that has been prepared for storage, drain the preservative and lubricating oil mixture
from the power end (crankcase). If the pump has a pinion bearing, remove the rear cover and apply recommended
crankcase lubricant (Refer to Table 2 in Section 6.2) to the pinion bearings. Reinstall the rear cover, drain plug,
breather/filler cap, piston cup seals, and any other components that were removed for storage. Once these steps
have been completed, follow the normal pump start up procedures outlined in this manual.
NOTE: American Mfg Company can factory prepare units for long term storage for a nominal fee if specified at the
time of order.
3.4 Precautions During Freezing Weather
Freezing weather can cause problems for equipment when pumping water-based fluids that expand in volume
when changing from a liquid to a frozen solid state. When water is left in a pump fluid end and exposed to
freezing temperatures, the expansion of the water as it freezes can rupture the fluid cylinder of the pump and cause
equipment damage. Injury may result when starting equipment that has been damaged.
Whenever the pump is stored or idle in conditions that are near or below freezing, any water based fluids should
be removed from the pump.
The best way to do this is to run the pump for a few seconds with the suction and discharge lines disconnected or
open to atmosphere. This will clear the majority of the fluid from the pumping chamber as well as the suction and
discharge manifolds. After the run, blow compressed air through the fluid end to remove all traces of fluid. Remove
the bottom plugs and cylinder covers from the fluid cylinder. Drain the liquid from the discharge valves first and then
the suction valves by lifting the valves. This ensures all fluid to be drained from the pumping chamber between the
suction and discharge valves. As an alternative to the previous procedure, a compatible antifreeze solution can be
circulated through the fluid end. RV antifreeze, propylene glycol, is recommended for this purpose. Remember that
any fluid that poses an environmental hazard or is toxic must be handled and disposed of properly.

4.0 Installation Guidelines
A proper installation is essential to optimal performance, long service life, and reduced maintenance requirements.
Take time to thoroughly plan all aspects of your installation.
4.1 General Location
It is important to position the pump on as flat and level a surface as possible to assist the splash oil lubrication
system. Park mobile equipment, such as sewer cleaner trucks or drilling machines, on as level a surface as possible.
Whenever possible the pump should be mounted in a clean, dry location with sufficient lighting and adequate
space for easy inspection and maintenance. Locate the pump as close to the suction source as possible to allow for
the shortest and most direct routing of the inlet piping.
4.2 Mounting Pump to Foundation and Power Source
The AME0413HD pump must be mounted in a vertical position only. Secure the pump to the mounting surface using
the holes provided in the pump base. The design of the AME0413HD pump allows the drive shaft to be rotated in
either direction. For units that are V-belt driven, check the alignment of the sheaves after the unit is installed on its
permanent mounting. Tighten belts to the proper tension as recommended by the belt manufacturer. Verify that the
sheaves are in line and parallel to each other with a straight edge.
CAUTION: Never operate the pump without the belt guard securely installed. For direct-coupled or spline-driven
units, ensure that the shafts are centered and parallel when the driver is mounted to the pump. Follow the coupling
maunufacturer instructions for installation procedures and tolerances.
CAUTION: Never operate the pump without a shaft guard securely installed.
4.3 Suction Piping Recommendations
Poor suction piping practices are a very common source of pump problems. To ensure proper operation it is very
important to follow good design practice in the installation of the suction system before the pump is operated.
A small amount of additional planning and investment in the piping system usually provides for better pump
performance and longer periods between service requirements. It is difficult to diagnose many pump problems
without the aid of a suction pressure gauge. For this reason, American Mfg Company recommends that a gauge
always be installed in the suction line directly before it enters the pump.
The suction line from the fluid source to the pump should be as short and direct as possible. Use rigid piping,
non-collapsible hose or a combination of both as circumstances require in your installation. The suction pipe size
should be at least equal to or one size larger than the pump inlet. Long piping runs, low suction heads, or indirect
