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.

NOTE: Not all materials are available for all
models. Refer to Section 2 for material options
for your pump.
CAUTION:
When choosing pump materials, be
sure to check the 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 limits are
based upon mechanical stress only. Certain
chemicals will signifi cantly reduce maximum
safe operating temperatures. Consult Chemical
Resistance Guide (E4) for chemical compatibility
and temperature limits.
WARNING:
Prevention of static sparking — If
static sparking occurs, fi re or explosion could
result. Pump, valves, and containers must be
grounded to a proper grounding point when
handling fl ammable
fl
uids and whenever
discharge of static electricity is a hazard.
CAUTION:
Do not exceed 8.6 bar (125 psig) air
supply pressure.
CAUTION:
The process fl uid and cleaning fl uids
must be chemically compatible with all wetted
pump components. Consult Chemical Resistance
Guide (E4).
CAUTION:
Do not exceed 82°C (180°F) air inlet
temperature for Pro-Flo X™ models.
CAUTION:
Pumps should be thoroughly fl ushed
before installing into process lines. FDA and
USDA approved pumps should be cleaned and/
or sanitized before being used.
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 fl uid
to fl 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 fi lter. A 5µ (micron)
air fi lter is recommended.
NOTE:
When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fi t.
(See torque specifi cations in Section 7.)
NOTE:
Cast Iron PTFE-fi
tted pumps come
standard from the factory with expanded PTFE
gaskets installed in the diaphragm bead of the
liquid chamber. PTFE gaskets cannot be re-used.
Consult PS-TG for installation instructions during
reassembly.
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:
Pro-Flo
®
pumps cannot be used in
submersible applications. Pro-Flo X™ is available
in both submersible and non-submersible options.
Do not use non-submersible Pro-Flo X™ models
in submersible applications. Turbo-Flo™ pumps
can also be used in submersible applications.
CAUTION:
Tighten all hardware prior to installation.
