DESCRIPTION
The PGPH High Pressure Pneumatic Pump is designed to manually generate up to
140 bar (2000 psi) gauge pressure or up to -0.95 bar (-14 psi) vacuum for quick and
accurate calibration of pressure gauges, transducers and other pressure measure-
ment instruments.
Standard Accessories
The standard accessories are as follows:
One G ¼’’ (male) plug for Pressure connectors
A set of seals (o-rings), type: NBR70 for Pressure connectors (size 6 × 2).

Connections and Parts
Pump lever
Shut-off valve. Isolates the pump form the measurement circuit.
Release valve. Clockwise to close, anticlockwise to open.
Pressure connector, G ¼", for instrument / calibrator. Hand tightened.
Vent connection/hole
Fine Adjust handwheel. Rotating clockwise increases pressure.
Pressure connector, G ¼", for instrument / calibrator. Hand tightened.
Equivalent with Pressure connector
Pressure/Vacuum selector. Pull out for pressure and push in for vacuum.
Do not change when pressurized!

OPERATION
Preparation
1. Select Pressure Mode .
2. Open Shut-off valve (counterclockwise) and Release valve.
3. Rotate Fine Adjust to mid position
4. Close Release valve
5. Connect instrument to be calibrated (Device Under Test, DUT) to Pressure con-
nector and the calibrator (pressure module, reference) to Pressure connector
. The location of the instrument and the calibrator may also be interchanged.
Pressure connectors and are equivalent. See also Leak Tests on page 6.
Calibration
6. Pump pressure/vacuum .
7. Close Shut-off valve (clockwise). See also notes further on.
8. Adjust pressure by rotating the Fine Adjust handwheel.
9. Repeat stages 6 to 8 until instrument's maximum pressure / deepest vacuum is
reached
When maximum pressure / deepest vacuum is reached continue as follows:
10.Gently open Release valve to release pressure/vacuum and close when ap-
proaching next calibration point.
11.Adjust pressure by rotating the Fine Adjust handwheel.
12.Repeat stages 10 and 11 until atmospheric pressure (or the instrument's meas-
urement span's pressure closest to atmospheric pressure) is reached.
End by opening Shut-off and Release valves. If you want to do several repeats,
restart from stage 3.

Keep in Mind
Immediately after a pressure change, the pressure may change slightly due to the
stretching/shrinking of the pressure measurement hose. Thermodynamic effects may
also cause pressure variation. In that case, adjust the pressure back to required value
using the Fine Adjust handwheel.
Do not exceed the max. operating pressure of the pump and the hose. Also observe
the pressure limit set by environmental conditions.
Ensure that there always is a reliable pressure indicator connected to the pump when
the pump is used.
If there is a strong counterforce while operating the pump lever, but no pressure
change is indicated, stop pumping and locate the fault. Always keep a reliable indi-
cator connected to the measurement system.
If the pump fails to indicate a pressure change after considerable pumping action of
the handle, check to assure that the connections between the pump, the hose end
and the attached instrument(s) are tight and retry pumping. Also check to assure that
all the unused output connectors are properly plugged.
If a pressure increase still cannot be obtained, it is possible that one or more of the
seals in the Pressure Pump is leaking and needs to be replaced.
Do not continue pumping if the functionality of the pump is not normal. Locate
the fault before you continue using the pump.
