Precautions - Read First!
TEMPERATURE LIMITS:
Nylon – 17.8°C to 93.3°C 0°F to 200°F
Neoprene – 17.8°C to 93.3°C 0°F to 200°F
Buna-N – 12.2°C to 82.2°C 10°F to 180°F
EPDM – 51.1°C to 137.8°C – 60°F to 280°F
FKM – 40°C to 176.7°C – 40°F to 350°F
Wil- Flex™ – 40°C to 107.2°C – 40°F to 225°F
Polyurethane 12.2°C to 65.6°C 10°F to 150°F
Saniflex™ – 28.9°C to 104.4°C – 20°F to 220°F
PTFE – 28.9°C to 148.9°C – 20°F to 300°F
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 176.7°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
engineering 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: Prevention of 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.
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 clamp bands and retainers 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 (see E4).
CAUTION: When removing the end cap using compressed
air, the air valve end cap may come out with considerable
force. Hand protection such as a padded glove or rag
should be used to capture the end cap.
NOTE: All non lube-free air-operated pumps must
be lubricated. Wilden suggests an arctic 5 weight oil
(ISO grade 15). Do not over-lubricate air supply.
Over- lubrication will reduce pump performance.
NOTE: UL-listed pumps must not exceed 3.4 bar
(50 psig) air supply pressure.
CAUTION: Only explosion proof (NEMA 7) solenoid
valves should be used in areas where explosion proof
equipment is required.
