WARNING! WARNING!
The Heritage PumpsTM air operated pumps are mechanical devices with moving
parts that are used to move fluid and create high pressure flows. Use extreme
caution and exercise all safety practices when performing maintenance or
operating these pumps. Do NOT ignore the warnings and cautions in this
publication. It is important to follow all instructions in this manual using only
approved methods, tools, and parts/materials. Do NOT permit the operation of any
questionable equipment or safety practices as this creates dangerous conditions to
personnel. Accidents are caused by careless unsafe acts and operating conditions.
SAFETY IS A CHIOCE AND IT IS YOUR RESPONSIBILITY! YOU MUST CHOOSE TO
PRACTICE SAFETY TO PROTECT YOURSELF AND OTHERS.
WARNING! WARNING!
BEFORE PERFORMING ANY MAINTENANCE OPERATIONS, THERE ARE IMPORTANT
SAFETY PRECAUTIONS TO PERFORM.
1. Disengage the power source to the pump. This should include using the
appropriate lockouts on air supply valves and electric supply to compressors
providing air to the pump.
2. Shut off the supply of fluid to the suction inlet of the pump.
3. Shut down any accessory equipment.
4. Bleed off all pressure in the discharge line of the pump.
FAILURE TO FOLLOW THE WARNINGS AND CAUTIONS IN THIS MANUAL COULD
RESULT IN DAMAGE TO PROPERTY, EQUIPMENT, AND SERIOUS BODILY INJURY OR
EVEN DEATH. MAINTENANCE AND REPAIR WORK SHOULD BE PERFORMED BY
COMPETENTLY TRAINED AND QUALIFIED PERSONNEL AND CONFORMS TO ANY
RELEVANT LOCAL REGULATIONS.

ATEX WARNING STATEMENTS
Pumps and Pump Packages
1. When installing a pump or pump package in a potentially explosive
environment, confirm that these conditions were specified at the time of
purchase and that the supplied equipment conforms to all requirements and
displays the appropriate ATEX nameplate or is supplied with a certificate of
conformity. Any questions as to the conformity of the equipment should be
directed to Heritage Pumps, LLC before installation and commissioning.
2. All fluids being processed should be maintained within specified safe
temperature limits. Failure to control fluid temperature could cause the
pump and/or system components to become a possible source of ignition due
to temperature rise. In cases where the fluid temperature is 70o C, the surface
temperature of the equipment will not exceed 80o C, provided the pump and
related system is installed, maintained, and operated as specified in this
manual.
3. All maintenance and repair work should be performed only by properly
trained competent personnel adhering to any and all local regulations.
4. All pneumatic equipment, controls, and safety devices must be suitably rated
for the environment and system pressure in which it is installed.
5. When the equipment is installed in an environment where the accumulation
of dust or gases is a risk, be sure that all equipment is properly grounded and
that only non-sparking tools are used for installation and maintenance.
6. Control/safety devices should be installed into the system to minimize the risk
of sparking as the result of mechanical overload. The power supply to the Air
Motor and auxiliary equipment should have an isolator switch or control valve
installed to disconnect and lockout in the off position. A check valve and relief

Heritage Pumps, LLCTM 7 www.heritagepumps.com
valve/safety head should be installed near the discharge port of the pump
fluid end. All system safety and control devices should be installed,
maintained, and operated in accordance to the respective manufacturer’s
instructions. Always check to be sure that all valves are in the open position
when starting the pumps to prevent rapid over pressurization of the system
and causing a possible failure.
7. Proper maintenance and operation of the pump and related auxiliary
equipment in accordance to the specific manufacturer’s instructions is
required to prevent premature failure of components which could create
potentially dangerous conditions and equipment failure. The regular routine
inspection and replacement of worn components is required to maintain the
safety and integrity of the system and related components.
8. In accordance to certain guidelines covered by legislation, the pump and its
components have been designed and tested to ensure safe operation when
properly installed, operated, and maintained. Heritage PumpsTM declares this
machinery safe to use for the duty specified as defined by the Declaration of
Incorporation of Conformity that is issued with this instruction manual.
9. The use of this equipment as classified higher than Category I as defined in
Article 9 of 97/23/EC is prohibited. For calculation purposes, the volume of
chambers is less than 1L.
AT THIS TIME THE HERITAGE PUMPS ARE NOT ATEX CERTIFIED; HOWEVER, THEY
DO CONFORM TO ATEX STANDARDS. HERITAGE PUMPS, LLC IS IN THE PROCESS
OF OBTAINING ATEX CERTIFICATION.

1.0 SYSTEM DESIGN AND LAYOUT
1.1 GENERAL CONSIDERATIONS
A properly designed layout will save time and minimize expense
during installation, operation and maintenance. It is important to
select the proper location for the pump to insure adequate positive
suction head to the pump inlet, which contributes to overall pump
efficiency. Piping design and layout is an even more important
design consideration. All suction lines should be as short and direct
as possible. There should be minimal bends and utilize full opening
valves and fittings to eliminate any flow restrictions. Optimal pump
operation and ease of maintenance should include other basic
considerations outlined below.
1.2 LIFTING-WARNING!
The pumps discussed in this manual can be safely lifted manually
by an individual; however, care should be taken to avoid accidental
bodily injury or damage to the pump from accidental dropping. Do
not lift the pumps by the air lines!
1.3 MOUNTING PUMP
1. When determining the location of the pump. Consider the
proximity to associated equipment, fluid supply, ease of
maintenance access, and any elements of environmental
contamination.
2. The pump mounting bracket should provide support under the
Cylinder Base, preferably securing the pump by the Stanchion
Rods. (See Heritage PumpsTM Mounting Bracket Assembly Part No.
17360).
3. The pump should be mounted level and perpendicular with the Foot
Valve and pump inlet connect at the bottom. An angular mounted

Heritage Pumps, LLCTM 10 www.heritagepumps.com
pump that is not perpendicular may have erratic operation and
difficulty priming.
4. The mounting method must provide adequate support to avoid any
flexing of the equipment or the system.
1.4 SUCTION LINE DESIGN AND SPECIFICATIONS
1. The suction line must be equal to or one size larger than the inlet
connection on the Foot Valve. The line should be as short and
straight as possible from the fluid reservoir.
2. A full opening ball or gate valve (no reduced port valves) should
be installed on the suction line at the fluid reservoir to permit
draining of the line or removal of any debris. The use of a Y-type
strainer in the suction line is recommended to prevent debris
from accidentally entering the Foot Valve of the pump.
3. Do not install flow meters or other instrumentation which would
restrict flow in the suction line.
4. Insure there is not any rise in the suction line which can collect
air of other fluid vapor.
5. If it is necessary to install a charge pump into the suction line, it
should have an output greater than the peak volume required to
fill the suction need of the pump on the suction stroke plus at
least 50%. A good rule of thumb is to use a charge pump with
double the output of the pump being supplied.
6. The suction line needs to be solidly and independently
supported without putting the pump in a strain to prevent
vibration from having any direct influence on the pump.
1.5 DISCHARGE LINE DESIGN AND SPECIFICATIONS
1. The discharge line should be equal to or larger than the
discharge port of the pump and sufficiently capable of handling
the maximum pump discharge pressure in the system.
