PS1 Clamped Metal
SECTION 1
WARNING:
Always wear safety glasses when operating a pump
to avoid eye injury. If diaphragm rupture occurs, material being
pumped may be 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” for material options for your pump.
NOTE:
UL-listed configured pumps have the following
temperature limits: UL 79 Buna-N =12.2°C to 52°C
(10°F to 125°F).
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.
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.
For UL-listed pumps, do not exceed 3.4 bar (50 psig) air supply
pressure.
CAUTION:
Do not exceed 82°C (180°F) air inlet temperature for
all models.
CAUTION:
The process fluid and cleaning fluids must be
compatible chemically with all wetted pump components.
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:
Thoroughly flush pumps before installing them into
process lines. Clean and/or sanitize FDA- and USDA- approved
pumps before using them.
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 SHIFT is available in both single-point
exhaust (submersible) and standard (non-submersible) options.
Do not use standard Pro-Flo SHIFT models in submersible
applications.
CAUTION:
For UL-listed pumps, all pipe connections
are to be made using UL classified gasoline-resistant
pipe compound.
CAUTION:
For UL-listed pumps, all installations
must conform to NFPA 30, NFPA 30A and other
applicable codes.
CAUTION:
For UL-listed pumps, air exhaust port is to
be connected to pipe or tubing to be routed outdoors or
other location determined to be equivalent.
CAUTION:
For UL-listed pumps, pump is to be
grounded using the jam-nut located at the top of the
long vertical carriage bolt. The ground connection is
marked with a tag having the grounding symbol.
CAUTION:
Before installation, tighten all hardware.
NOTE:
Materials of construction and elastomer material may
influence suction lift parameters. Please refer to “Performance”
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”).
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.
NOTE:
The Safety Supplement document is a part of the
manual. Please refer to the Safety Supplement document for a
complete list of safety considerations including considerations for
safe operation and maintenance of pumps marked for ATEX
environments before starting the pump.
WARNING:
This product can expose you to chemicals including
Nickel, Chromium, Cadmium, or Cobalt, which are known to the
State of California to cause cancer and/or birth defects or other
reproductive harm. For more information, go to
