Precautions - 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

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 176.7°C (350°F) but
polypropylene has a maximum limit of only 79.4°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.
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 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 (see 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
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 V™ is available
in
both submersible and non-submersible options. Do
not use non-submersible Pro-
Flo V™
models in
submersible applications. Turbo-
Flo™
pumps can be
used in submersible applications.
CAUTION:
Tighten all hardware prior to installation.
