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
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:
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:
P2 pumps are made of virgin plastic and are not
UV-stabilized. Direct sunlight for prolonged periods can cause
deterioration of plastics.
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.
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.
CAUTION:
P2 PTFE-fitted pumps come standard
from the factory with expanded PTFE gaskets.
(See Gasket Kit Installation.)
CAUTION:
Do not over-tighten the air inlet reducer
bushing. Too much torque on the reducer bushing
may damage the air valve muffler plate. Do not
exceed 0.9 Nm (8.0 in-lb).
NOTE:
When reinstalling the outer pistons, apply two
(2) drops of Loctite
®
246 to the shaft internal threads
before the diaphragm assembly.
