1.0 SAFETY WARNINGS
Please read and observe all warnings contained in this operations manual before making any
attempt to operate the equipment.
Misuse of equipment
Misuse of equipment can cause serious bodily injury. Use the equipment only for its intended
purpose and do not attempt to modify it in any way. Care should be taken to prevent over
pressurization of the pump, hose lines and accessories connected to it. Use only IPM
designated parts for re-building or repairing this equipment. Use the pump only with compatible
fluids. Improper use of this equipment could result in fluid being sprayed on the skin or in the
eyes of user, serious bodily injury, property damage, fire or explosion.
Daily maintenance inspection should be made on pumps and equipment and all worn or
damaged parts should be re-placed immediately. Do not use pumps, components or hose lines
as leverage to move equipment to avoid damage and injury. Do not alter this equipment as
doing so could cause it to function incorrectly and/or cause serious injury. Altering this
equipment in any way will also void any and all warranty guarantees from the manufacturer.
Material & fluid compatibility
Always ensure the chemical compatibility of the fluids and solvents used in the fluid section of
these pumps, hoses other components. Check the chemical manufacturer’s data sheets and
specification charts before using fluids or solvents in this pump to ensure compatibility with
pumps, inner hose lining and outer hose covering.
Pressurized hoses
Because the hoses are pressurized they can present a danger should the fluid escape due to
damage, worn parts or general miss-use. Escaping fluid can splash or spray operator, causing
serious bodily injury and/or damage to equipment and property. Ensure that the hoses do not
leak or rupture due to wear, misuse or damage.
Before each use, ensure that the fluid couplings are tight and all clips/pins/plugs are secured.
Inspect the entire length of hose for wear, cuts, abrasions, bulging cover and/or loose
connections. These conditions may cause the hose to fail and result in splashing or spraying of
chemicals on the skin or in the eyes of operator and cause serious injury and/or property
damage.

Warning
To reduce the risk of static sparking or splashing fluid in the eyes or on the skin,
follow the Pressure Relief Procedure before flushing.
For your safety, read the ire or Explosion Hazard before flushing and follow all the
listed recommendations.

Pressure specification
The maximum working pressure of this equipment for fluids and air is 180 psi (12.4 bars).
Ensure all equipment and accessories used with this pump are rated to withstand the maximum
working pressure of this pump. Never exceed the maximum working pressure of the pump, hose
lines or any other components attached to the pump itself.
Pressure relief procedure
In order to avoid the risk of serious injury to operators from splashing/spraying chemicals, the
following safety procedures should be used. This procedure should be used when shutting down
the pump, performing general maintenance, repairing a pump or other components of the
system, replacing components or when pumping operation is ceased.
1. Close the air valve to the pump.
2. Use the air bleed down valve to relieve the air pressure in the system.
3. Relieve the fluid pressure by holding a grounded metal pail in contact with the metal part
of the fluid dispense valve and slowly opening the valve.
4. With a container ready to catch the fluid, open the drain valve.
5. It is a good practice to leave the drain valve open until it is time to dispense fluid again.
If you are unsure that the fluid pressure has been relieved due to a blockage in a component or
a hose, carefully relieve the pressure by carefully loosening the hose end coupling to allow the
fluid pressure to escape slowly. After the pressure has been relieved, the fitting can then be
removed and any blockages removed. If the pump is to remain idle for only a short period of
time, it is not necessary to empty the wet cup.
lushing
1. The pump is tested with lightweight oil, which is left in to protect the pump parts. If
the fluid you are pumping may become contaminated by oil, flush oil from pump with a
compatible solvent before use. Follow the flushing instruction below.
2. When pumping fluids that set up or solidify, flush the system with a compatible
solvent as often as necessary to remove build-up of solidified chemicals in the pump or
hoses.
3. If the pump is being used to supply a circulating system, allow the solvent to circulate
through the entire system for at least 30 minutes every 48 hours or more often if
necessary to prevent settling and solidification of chemicals.
4. Once a pump is committed to a particular chemical, it is good practice to identify which
chemical a particular pump is designated for to eliminate the possibility of mix up and
contamination.
5

Shutdown
For overnight shutdown, follow the Pressure Relief Procedure. Always stop the pump
at bottom of the stroke to prevent the fluid from drying on the exposed displacement rod and
damaging the throat packing.
Hazards from fire or explosion
Hazards exist where sparks can ignite vapors or fumes from combustible chemicals or other
hazardous conditions exist such as explosive dust, etc. These sparks can be created from
plugging in or unplugging an electrical supply cord or from the static electricity generated by the
flow of fluid through the pump and hose.
Every part of the equipment must be properly grounded to prevent static electricity from
generating a spark and causing the pump or system to become hazardous. These sparks can
cause a fire, explosion, property and equipment damage and serious bodily injury. Ensure that
the pump and all components and accessories are properly grounded and that electrical supply
cords are not plugged in or unplugged when these hazards exist.
hould any evidence of sparks or static electricity exist, discontinue pump operation
immediately. Investigate the source of the static electricity and correct the grounding problem.
Do not use the system until the grounding problem is repaired.
Grounding procedure
Grounding of the pump and all components are necessary to minimize the possibility of sparks
due to static electricity. Grounding must be in compliance with local electrical codes. Check with
the local authorities for requirements in your area and with the type of equipment being used.
Ensure that all the following equipment are grounded correctly:
1. Pump : Loosen the lock screw to allow insertion of one end of a minimum
sized 12 gauge wire into the bore hole of the grounding lug. Insert wire
and tighten the lock screw securely. ecure the other end of the
ground wire to a true earth ground. ee FIG. A

2. Air compressor : Follow the grounding procedures as recommended by the
compressor manufacturer.
3. Air hoses : Always use grounded air hoses.
4. Fluid container used
to supply the system : Grounding must be done according to local electrical codes.
5. Fluid Hoses : Always use grounded fluid hoses.
6. Dispensing Valve : The valve must be metal to conduct through the fluid hose
to the pump which must be properly grounded.
7. Dispensing Point : Grounding must be done according to local electrical codes.
8. olvent Containers : Grounding must be done according to local electrical codes.
use only metal conductive pails that are properly grounded.
9. Grounding while
dispensing, cleaning Maintain conductivity by firmly securing the metal part of the
or relieving pressure : dispensing valve to the side of a grounded metal container.
It is very important that the hoses used for both air and fluid dispensing be a grounding type and
that ground continuity is maintained at all times during operation. Regular checks of the hose
ground resistance (with a resistance meter using a suitable range) and a comparison to the
manufacturer’s specification will ensure that the ground is within specifications. If it is not within
specified limits it should be replaced immediately.
Solvent cleaning
While cleaning the system with solvent, secure the metal part of the dispensing valve in contact
with a grounded metal pail to minimize the possibility of splashing/spraying of chemicals on the
skin, in the eyes and around static sparks. Use low fluid pressure for additional safety.
Hazards from moving parts
Use the Pressure Relief Procedure to prevent the pump from starting unintentionally or
unexpectedly. Be aware of moving parts that present a pinching hazard to fingers or other body
parts. tay clear of these moving parts at all times when starting or operating the pump.
Safety standards
afety standards have been established by the United tates Government under the
Occupational afety and Health Act. These standards should be consulted as they apply to the
hazards and type of equipment being used.
