READ THESE WARNINGS AND SAFETY PRECAUTIONS PRIOR
TO INSTALLATION OR OPERATION. FAILURE TO COMPLY
WITH THESE INSTRUCTIONS COULD RESULT IN PERSONAL
INJURY AND OR PROPERTY DAMAGE. RETAIN THESE
INSTRUCTIONS FOR FUTURE REFERENCE.
This product can expose you to chemicals
including Nickel, Chromium, Cadmium, or Cobalt, which are
known to the State of California to cause cancer and/or birth
defects or other reproductive harm. For more information, go
to www.P65Warnings.ca.gov.
WARNING Pump, valves and all containers must be
properly grounded prior to handling flammable fluids and/or
whenever static electricity is a hazard.
WARNING Prior to servicing the pump, ensure that
the air and fluid lines are closed and disconnected. While
wearing personal protective equipment, flush, drain and
process liquid from the pump in a safe manner.
WARNING The TX marking refers to the maximum
surface temperature depending not on the equipment
itself, but mainly on operating conditions. In this case,
the maximum surface temperature depends upon the
temperature of the process fluids.
CAUTION The temperature of the process fluid
and air input must be no more than 36°F (20C) less of the
maximum temperature allowed for the appropriate non-
metallic material. See the list of temperatures below for each
material’s maximum recommended temperature:
Buna-N (Nitrile): 10°F to 180°F (-12°C to 82°C)
Geolast®: 10°F to 180°F (-12°C to 82°C)
EPDM: -40°F to 280°F (-40°C to 138°C)
Santoprene®: -40°F to 225°F (-40°C to 107°C)
FKM: -40°F to 350°F (-40°C to 177°C)
PTFE: 40°F to 220°F (4°C to 104°C)
Polyethylene: 32°F to 158°F (0°C to 70°C)
Polypropylene: 32°F to 180°F (0°C to 82°C)
PVDF: 0°F to 250°F (-18°C to 121°C)
Nylon: 0°F to 200°F (-18°C to 93°C)
Temperature limits are solely based upon mechanical stress
and certain chemicals will reduce the maximum operating
temperature. The allowable temperature range for the
process fluid is determined by the materials in contact with
the fluid being pumped. Consult a chemical resistance
guide for chemical compatibility and a more precise safe
temperature limit. Always use minimum air pressure when
pumping at elevated temperatures.
CAUTIONS — READ FIRST!
WARNING
CAUTION
= Hazards or unsafe practices
which could result in severe
personal injury, death or
substantial property damage
= Hazards or unsafe practices
which could result in minor
personal injury, product or
property damage.
CAUTION Do not lubricate air supply.
CAUTION Do not connect a compressed air source to
the exhaust port of the pump.
WARNING Use only with liquid process fluid.
WARNING Maintenance must not be performed when
a hazardous atmosphere is present.
CAUTION Do not exceed 120 psig (8.3 bar)
air-inlet pressure.
CAUTION Do not exceed 10 psig (0.7 bar)
or 23 ft-H2O suction pressure.
CAUTION Ensure all wetted components are
chemically compatible with the process fluid and the cleaning
fluid.
CAUTION Ensure pump is thoroughly cleaned and
flushed prior to installation into a process line.
CAUTION Always wear Personal Protective
Equipment (PPE) when operating pump.
CAUTION Close and disconnect all
compressed air and bleed all air from the pump
prior to service. Remove all process fluid in a safe manner
prior to service.
CAUTION Blow out all compressed air
lines in order to remove any debris, prior to
pump installation. Ensure that the muffler is properly
installed prior to pump operation.
CAUTION Ensure air exhaust is piped to
atmosphere prior to a submerged installation.
CAUTION Ensure all hardware is set to
correct torque values prior to operation.
