Safety Precautions and Warnings - 6
Safety Precautions and Warnings
Warning: Read the User Manual carefully prior to setting up and
using the pressure pump. Do not use the PGL in any other way than
as described in this User Manual. Do not connect the pump to an
external pressure source.
Warning: Only personnel with good experience and knowledge of
pressure media, pressure instruments and connections are allowed to
work with the pressure pump. Incorrect use may cause damage to the
pump, the instrument connected to the pump and/or personal injury.
Warning: Use eye shields. The use of a relief valve for overpressure
protection is recommended. If a relief valve is used, remember to
occasionally check its functionality.
Warning: Vent external systems before connecting to the pump.
Ensure that all connections are made correctly and that the hoses and
connectors are undamaged and free of impurities. Do not use faulty
hoses or connectors. Use only measuring hoses provided by Beamex
or other reliable suppliers. Observe the effect of the operational
conditions to the maximum pressure allowed in the hose.
Warning: Always depressurize the PGL when it is left on its own.
Avoid possible damage when suddenly applying pressure to low
pressure and small chamber gauges. Do not exceed the safety
pressure limit (4 bar / < 60 psi). The environmental conditions
(ambient pressure and temperature) may restrict the allowed
maximum pressure to a lower level than the pump and the hose
enable.
Warning: Compressed air may cause problem in explosive or
corruptive environments. In order to avoid any damage, do not
overtighten the connectors.
Warning: Store the pump in a dry and non-corruptive environment. If
the pump is accidentally dropped, it may be damaged. Do not use the
pump before it is inspected at Beamex’s service.
Warning: Any safety problems or damages caused by incorrect
operation, are beyond Beamex's responsibility.

Operating Instructions
Positive Pressure Calibration
1. Open the Release Valve by turning the Fine Adjust Knob
counterclockwise to the maximum or until 2-3 threads are visible. Rotate
the Coarse Adjust Handwheel counterclockwise to the maximum.
2. Close the Release Valve by turning the Fine Adjust Knob clockwise to the
middle position.
3. Connect the calibrator (pressure measurement module) and the instrument
to be calibrated (device to be tested) to the pressure output fitting using
the Beamex 40 bar pressure T-hose or similar. If needed, compensate the
small pressure offset by turning the Fine Adjust Knob counterclockwise
until the output pressure is 0 barg / 0 iwcg.
4. Increase the pressure close to the next calibration point by rotating the
Coarse Adjust Handwheel clockwise.
5. Advance to the calibration point by turning the Fine Adjust Knob. Wait for
a while (about 1 minute) and fine-tune the output pressure back to the set
point.
6. Continue to the next calibration point by repeating steps 4 and 5 in this
instruction until you reach the calibration point with the highest pressure.
7. Decrease the pressure close to the next calibration point by rotating the
Coarse Adjust Handwheel counterclockwise. Alternatively, open the
release valve if it was your final set point.
8. Advance to the calibration point by turning the Fine Adjust Knob. Wait for
a while (about 1 minute) and fine-tune the output pressure back to the set
point.
9. Continue to the next calibration point by repeating steps 7 and 8 in this
instruction until all calibration points are done.
10. Begin another calibration run by starting from step 4 in this instruction or
end calibration by opening the Release Valve.

Operating Instructions - 12
Negative Pressure (Vacuum) Calibration
1. Open the Release Valve. Rotate the Coarse Adjust Handwheel clockwise
to the maximum.
2. Close the Release Valve and set the Fine Adjust Knob to the middle
position.
3. Connect the calibrator (pressure module, reference) and the instrument
to be calibrated (device to be tested) to the pressure output fitting using
the Beamex low pressure hose (max 40 bar) or similar. If needed,
compensate the small pressure offset by turning the Fine Adjust Knob
counterclockwise until the output pressure is 0 barg / 0 iwcg.
4. Decrease the pressure close to the next calibration point by rotating the
Coarse Adjust Handwheel counterclockwise.

hose is connected needs to be compensated, just turn the Fine Adjust
Knob slightly counterclockwise until the pressure reading is 0 mbarg /
0 iwcg.

Operating Instructions - 13
Important to Consider
The operating principle of the PGL pump is based on an adjustable volume.
When changing the volume in a closed pressure system, it causes the pressure
to change. The PGL has a certain range in the volume adjustment and the
effect of that on the pressure change in the system depends directly on the total
volume of the system:
• For a system with a very large volume, the PGL can only make small
pressure adjustments and you may not reach the maximum pressure
specified for the PGL.
• For a system with a very small volume, the PGL can adjust the pressure
significantly more, even over the maximum safety pressure. Please take this
into account when using the PGL and don’t exceed the safety pressure 4
bar / 60 psi in any circumstances.
Immediately after a pressure change, the pressure may change slightly due to
the thermodynamic effects. In that case, adjust the pressure back to required
value using the Fine Adjust Knob.
Ensure that there is always a reliable pressure indicator connected to the pump
when the pump is being used.
If there is a strong counterforce while operating the pump, but no pressure
change is indicated, stop using the pump and locate the error. Always keep a
reliable indicator connected to the measurement system.
If the pump fails to indicate a pressure change, make sure that the connections
between the pump, the hose end and the attached instrument(s) are tight and
then retry pumping. Also check that possible unused connectors are properly
plugged.
If a pressure increase still cannot be obtained, it’s possible that one or more of
the seals in the pump is leaking and needs to be replaced.
Avoid making calibrations in direct sunlight as it may heat up the setup and
cause pressure fluctuation and unstable pressure readings.
Do not use the pump if the functionality of the pump is not normal. Locate
the error before you continue using the pump.
A full list of warnings is included in this User Manual.

Troubleshooting - 14
Troubleshooting
The System is not Holding the Set Pressure.
