PUMP TEMPERATURE LIMITS
-12.2°C to 65.6°C 10°F to 150°F
CAUTION: The discharge pressure generated by this
pump is approximately 26 times the inlet air pressure
supplied.
CAUTION: Do not apply compressed air to the exhaust
ports — pump will not function.
CAUTION: The model H38/3200D is designed to pump
clean fluid such as hydraulic fluid and should not be
used for pumping solid objects or particles. Whenever
the possibility exists that solid objects or particles may
be sucked into the pump, a strainer should be used on
the suction line.
CAUTION: Do not over-lubricate air supply — excess
lubrication will reduce pump performance. Pump is pre-
lubed with NLGI Grade 2 molybdenum grease.
CAUTION: The H38/3200D is designed for open loop
systems.
CAUTION: Maximum temperature limits are based
upon mechanical stress only. Certain chemicals will
significantly reduce maximum safe operating tempera-
tures. Consult Wilden's Chemical Resistance Guide
(see publication E-4) 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.
WIL-11181-E-04
CAUTION: Do not exceed 8.6 bar (125 psig) air supply
pressure.
CAUTION: The process fluid and cleaning fluids must
be chemically compatible with all wetted pump com-
ponents (see publication E-4).
CAUTION: Pumps should be thoroughly flushed with
water before installation.
CAUTION: Always wear safety glasses and proper
protection when operating and maintaining pump.
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 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.
CAUTION: Blow out air line for 10 to 20 seconds
before attaching to pump to make sure all pipeline
debris is clear. Use an in-line air filter. A 5µ (micron) air
filter is suggested.
NOTE: Before starting disassembly, mark a line from
each liquid chamber to its corresponding air chamber.
This line will assist in proper alignment during reassem-
bly.
CAUTION: Pump is not rated for UL 79 service.
CAUTION:
H38
CAUTION: Tighten all hardware prior to installation.
CAUTION: All piping valves, gauges and other com-
ponents installed on the liquid discharge must have a
minimum pressure rating of 220.6 bar (3,200 psig).
