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.

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. 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 177°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 for chemical compatibility and
temperature limits.
WARNING:
Prevent 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.
CAUTION:
Do not exceed 82°C (180°F) air inlet
temperature for all models.
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:
When installing two-piece 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:
Pro-Flo
®
SHIFT pumps are available with a
single-point-exhaust option. Do not use standard pumps in
submersible applications.
CAUTION:
Tighten all hardware prior to installation.
