Precautions - Read First!
WARNING:
Always wear safety glasses when
operating a pump to avoid eye injury. If diaphragm
rupture occurs, material being pumped maybe forced
out of the air exhaust.
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. See "Wilden
Pump Designation System on page 5 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 on mechanical
stress only. Certain chemicals will reduce maximum safe operating
temperatures significantly. Consult the 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:
All Wilden pumps are capable of passing solids. Use a
strainer on the pump intake to ensure that the pump's rated solids
capacity is not exceeded.
CAUTION:
Do not exceed 8.6 bar (125 psig) air supply pressure.
CAUTION:
The process fluid and cleaning fluids must be compatible
chemically with all wetted pump components.
CAUTION:
Do not exceed 82°C (180°F) air
inlet temperature for all models.
CAUTION:
Thoroughly flush pumps before installing
them into process lines. Clean and/or sanitize FDA-
and USDA- approved pumps before using them.
CAUTION:
Before attempting any maintenance or repair,
disconnect the compressed air line to the pump and allow all
air pressure to bleed from the 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.
Be aware of any hazardous effects of contact with your
process fluid.
CAUTION:
Before attaching the air line to the pump,
blow out the air line for 10 to 20 seconds 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.
CAUTION:
Before installation, tighten all hardware.
NOTE:
Materials of construction and elastomer material
have an effect on suction lift parameters. Please refer
to "Performance " on page 8 for specifics.
NOTE:
When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit. (See
"Maximum Torque Specifications" on page 21.)
NOTE:
Some PTFE-fitted 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.
NOTE:
In the event of a power failure, close the shut-off
valve if you do not want the pump to restart when the
power returns.
