Precautions - Read First!
WARNING: 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.

4°C to 149°C (40°F to 300°F) - 13 mm (1/2") and 25 mm (1") models only.
NOTE: Not all materials are available for all models. See "Wilden Pump Designation System
on page 5 for material options for your pump.
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: FKM has a
maximum limit of 178°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 significantly reduce maximum safe
operating temperatures. Consult Chemical Resistance Guide (E4) for
chemical compatibility and temperature limits.
CAUTION: Prevention of static sparking — If static
sparking occurs, fire or explosion could result. Pump,
valves, and containers must be grounded to a proper
grounding point when handling flammable fluids and
whenever discharge of static electricity is a hazard.
CAUTION: Do not exceed 8.6 bar (125 psig) air
supply pressure.
CAUTION: The process fluid and cleaning fluids
must be chemically compatible with all wetted pump
components. Consult Chemical Resistance Guide
(E4).
CAUTION: Pumps should be thoroughly flushed
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 fluid to flow 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 filter. A 5μ (micron) air filter is
recommended.
CAUTION: Pro-Flo pumps cannot be used in submersible
applications
NOTE: When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit.
(See torque specifications in Section 7.)
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.
