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.
CAUTION:
Maximum temperature limits are based upon
mechanical stress only. Certain chemicals will significantly
reduce maximum safe operating temperatures. Consult the
Chemical Resistance Guide for chemical compatibility and
temperature limits.
CAUTION:
Always wear safety glasses when operating pump.
If diaphragm rupture occurs, material being pumped may be
forced out air exhaust.
WARNING:
Prevent static sparking
—
If static sparking occurs,
fire or explosion could result. Pump, valves, and containers
must be properly grounded 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:
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. Thoroughly flushed before installing into process
lines. FDA- and USDA-approved pumps should be cleaned
and/or sanitized before being used.
CAUTION:
Blow out air line for 10 to 20 seconds before
attaching to pump to make sure all pipe line debris is clear.
Use an in-line air filter. A 5µ (micron) air filter is
recommended.
NOTE:
Tighten all fasteners prior to installation. Fittings
may loosen during transportation.
NOTE:
When installing PTFE diaphragms, it is important to
tighten outer pistons simultaneously (turning in opposite
directions) to ensure tight fit.
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:
Verify the chemical compatibility of the process
and cleaning fluid to the pump’s component materials in the
Chemical Resistance Guide.
CAUTION:
Only explosion proof (NEMA 7) solenoid valves
should be used in areas where explosion proof equipment is
required.
CAUTION:
Do not lubricate lube-free pumps.
CAUTION:
The A2 pump is not submersible.
