The PPA500 Pneumatic Hand
Pump is a compact, lightweight,
portable, hand-operated pressure
and vacuum pump. When a digital
calibrator is added the unit can be
used to calibrate or check pressure
measuring devices in the field. No
external power or high pressure
bottles are required. The PPA500 is
completely assembled and ready to
connect to the pressure device to
be calibrated. Calibration is quick
and simple since the pump is taken
directly to the pressure device. This
pneumatic pump provides a source
of air pressure, 0-500 psig (600 psi
max.), or vacuum, 0-28" Hg.
1. Isolate the device to be
calibrated. CAUTION: Do not
connect to high pressure
sources. Safe operating
procedures must be exercised to
avoid personal injury and
damage to the calibration
system.
2. Connect the pump and calibrator
to the pressure device to be
calibrated. Make sure the
connection is pressure tight and
be certain to use Teflon tape to
prevent leakage.
3. Turn the knurled knob on the
needle valve clockwise to close.
NOTE: Hand tighten only to
prevent damage to the valve
seat.
4. Using a small screwdriver, set
the shuttle valve to "pressure or
vacuum". Note that "P" and "V"
are stamped on the sides of the
pump body.
5. Squeeze the handles until the
desired or approximate pressure
is obtained. Additional force is
required as the pressure is
increased.
6. The pressure can be decreased
with the needle valve.
7. The pressure can be "fine tuned"
with the vernier knob. To increase
pressure, turn the vernier knob
clockwise. Turning the vernier
knob counterclockwise will
decrease pressure. NOTE: The
vacuum reading increases
when the vernier knob is turned
counterclockwise.
8. When the calibration procedure
is completed, bleed the pressure
before disconnecting the unit.
CAUTION: To prevent personal
injury, the pressure must be
reduced to zero before
disconnecting any element of
the system.
9. Store the unit in a carrying case
or other safe location.
Pump Valve Assembly
Cleaning Instructions
Occasionally, the PPA500 may not
work properly due to dirt or other
contamination of the internal valve
assembly. Use the following
procedure for cleaning the valve
assembly.
1. Using a small screwdriver,
remove the 2 valve retention
caps located on opposite sides of
the pump below the
pressure/vacuum switch.
2. After the caps have been
removed, gently remove the
spring and o-ring assembly.
3. Set aside the valve assemblies
in a safe area and clean out the
valve body using a cotton swab
soaked in IPA (isopropyl
alcohol).
4. Repeat the process several
times using a new cotton swab
each time until there is no
remaining evidence of
contamination or dirt.
5. Operate the pump handles
several times and recheck for
contamination.
6. Clean the o-ring assembly and
the o-ring on the retention caps
with IPA and inspect the o-rings
closely for any damage or
excessive wear. Replacements
are included in the repair kit, if
needed.
7. Inspect the springs for wear or
loss of tension. They should be
approximately 8.6 mm long in
the relaxed state. If shorter, they
may not provide sufficient
sealing tension. Replace if
needed.
8. Once all parts have been
cleaned and inspected, reinstall
the o-ring and spring assembly
into the valve body.
9. Reinstall the retention caps and
gently tighten each cap.
10. Seal the output port and
operate the pump to at least
50% of capacity.
11. Release the pressure and
repeat several times to ensure
that the o-rings seat properly.
