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: PTFE has a maximum limit of 104°C (220°F) but
polypropylene has a maximum limit of only 79°C (175°F).
CAUTION:
Do not apply compressed air to the exhaust ports
—
pump will not function.
CAUTION :
Do not over-lubricate air supply
—
excess
lubrication will reduce pump performance. Pump is pre-lubed
with NLGI Grade 2 white EP grease.
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.
NOTE:
Do not exceed 6.9 bar (100 psig) air supply
pressure for P1500 polypropylene pumps.
CAUTION:
Do not exceed 8.6 bar (125 psig) air
supply pressure for P1500 PVDF pumps.
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 recommend.
NOTE:
When installing PTFE diaphragms, it is
important to tighten outer pistons simultaneously
(turning in opposite directions) to ensure tight fit.
WARNING:
Tighten all bolts and retainers prior to
installation. Fittings may loosen during transportation.
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:
Pump is not rated for U.L. 79 service.
For
U.L. 79 transfer use Wilden’s U.L.
-approved
T Series pump.
NOTE:
The elbows and tees have bosses that are
designed to be tapped with a 9.5 mm NPT (3/8”)
fitting for draining the pump during maintenance.
CAUTION:
The P1500 pump is not submersible.
