HS430S High Pressure Bolted 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.
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.
WARNING:
Prevention of static sparking — If static sparking
occurs, fire or explosion could result. Pump, valves, and
containers must be grounded to a proper grounding point
when handling flammable fluids and whenever discharge of
static electricity is a hazard.
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.
CAUTION:
Do not exceed 82°C (180°F) air inlet temperature
for all models.
CAUTION:
All piping, valves, gauges and other components
installed on the liquid discharge must have
a minimum pressure rating of 20 .7 bar (300 psig).
CAUTION:
The discharge pressure generated by this pump
is 3X the inlet pressure supplied.
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:
Before installation, tighten all hardware.
CAUTION:
The HS430S is not submersible.
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
