CAUTIONS - READ FIRST
CAUTION: Do not apply compressed air to the
exhaust port – pump will not function.
CAUTION: Do not over-lubricate air supply – excess
lubrication will reduce pump performance. Pump is
pre-lubed.
TEMPERATURE LIMITS:
Neoprene -17.7°C to 93.3°C 0°F to 200°F
Buna-N -12.2°C to 82.2°C 10°F to 180°F
EPDM -15.1°C to 137.8°C -60°F to 280°F
Viton -40°C to 176°C -40°F to 350°F
Santoprene -40°C to 107°C -40°F To 225°F
PTFE -4°C to 104°C 40°F to 220°F
Polypropylene 0°C to 79°C 32°F to 175°F
CAUTION: Check temperature limits for all wetted
components. Example: Viton®has a maximum
limit of 176.7°C (350°F) but polypropylene has a
maximum limit of only 79°C (175°F).
CAUTION: Maximum temperature limit are based
upon mechanical stress only. Certain chemicals
will signicantly reduce maximum safe operating
temperatures.
WARNING:Prevention of static parking – if static
sparking occurs, re or explosion could result.
Pump, valves, and containers must be grounded to
a proper grounding point when handling ammable
uids and whenever discharge of static electricity
is a hazard.
CAUTION: Do not exceed 8.6 bar (125psig) air
supply pressure.
CAUTION: The process uid and cleaning uids
must be chemically compatible with all wetted
pump components.
CAUTION: Do not exceed 79°C (174°F) air inlet
temperature.
CAUTION: Pumps should be thoroughly ushed
before installing into process lines.
CAUTION: Always wear safety glasses when
operating pump. If diaphragm rupture occurs,
material being pumped may be forced out air
exhaust.
CAUTION: Before any maintenance or repair is
attempted, the compressed air line to the pump
should be disconnected and all air pressure
allowed to bleed from pump. Disconnect all intake,
discharge and air lines. Drain the pump by turning
it upside down and allowing any uid to ow into a
suitable container.
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to pump to make sure all pipeline
debris is clear. Use an in-line air lter. A 5µ (micron)
air lter is recommended.
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure a tight t.
(See torque specications.)
NOTE: Before starting disassembly, mark a line
from each liquid chamber to its corresponding air
chamber. This line will assist in proper alignment
during reassembly.
CAUTION: Tighten all hardware prior to installation.
CAUTION: 1/4” pump is not submersible
