1 Introduction
1.1 Description
The PGHH hydraulic calibration pump is designed to manually generate up to 700 bar
(70 MPa, 10 000 psi) for quick and accurate calibration of pressure gauges, transducers
and other pressure measurement instruments.
Recommended test fluids to be used with the pump are: mineral based hydraulic oils or distilled water.
Do not use solvents or synthetic fluids that will adversely affect the operation of the pump.
If used with distilled water:
• After each usage, the instrument has to be emptied and let dry out (drain screw at the bottom
of the reservoir);
• As soon as first cloudiness, particles or dirt become visible: change the fluid.
Read the instruction manual carefully prior to setting up and using the pressure pump.
The pressure built up internally during use can be extremely high.
Only personnel with good experience and knowledge of high pressure media, high pressure instruments
and connections are allowed to work with the pump. Incorrect use may result in damage to the pump,
the instrument connected to the pump and/or personal injury.

2 Operation
Wear protective glasses.
Do not use PGHH in any other way than as described in this manual.
Use only the connectors provided with the pump. Impurities from wrong materials may plug the pump.
Do not exceed the maximum operating pressure of the pump and the hose. Also observe the pressure
limit set by environmental conditions and the used pressure medium.
The pump is tested using water. Small amounts of water may still be inside the pump when you
receive it. Flush the pump with the pressure media to be used before connecting any instruments to it.
If you use water as the pressure medium, make sure that you store PGHH in temperatures above the
freezing point.
2.1 Operating instructions
1. Connect the optional external pressure module (EXT) to the pump (see 3 in figure 1)
using the appropriate seals (it is strongly recommended that the bonded seal
under the plug is used under 600 bar and copper seal above 600 bars).
Ensure that the measurement range of the connected module is appropriate.
2. Remove filling plug and fill reservoir (for 2/3 to max. 3/4) with the appropriate fluid
(don’t exceed the maximum level) and replace plug.
7
Ensure that the process media is compatible with the pressure media used in the pump. Make sure
that impurities are removed from the measurement system. From time to time the pressure media
used in the pump should be renewed.
The maximum total volume of the measurement system may not exceed 200 cc (12.2 cubic inches).
The volume inside PGHH is less than 1 ml (on the pressurized side, not the reservoir, with maximum
volume in the fine control). The volume of the unpressurized Pressure Measurement Hose is 3.5 ml
per meter.

3. Connect the instrument to be tested to the Pressure Measurement Hose and attach
it to the pump. Be sure that all the output connectors are properly plugged
or connected to an instrument to avoid leakage (see figure 2).
Do not connect the pump to the external pressure source.
Use only the measuring hose provided by Beamex. Observe the effect of the operational conditions to
the maximum pressure allowed in the hose. The specifications can be found in chapter 4.
Ensure that all connections are made correctly and that the hose and the connectors are undamaged.
Do not use faulty hoses or connectors.

The pump is made out of anodized aluminium - avoid too much strength while tightening the connectors.
The maximum torque is 15 Nm.

4. Adjust the fine control (1 in figure 1) to “the middle”. Make sure the stroke
selector /switching knob (7 in figure 1) is set to prime fully out. If not, squeeze
handles fully in and press the selector (see figure 3).
To expel the air from the pump:
close the vent valve, increase the pressure (for example up to 50 bar) and after
that, open the vent valve.
or optionally
connect the hose to PGHH but not the instrument to be calibrated. Pump until
drops of water/oil come out of the end of the hose. Then connect the instrument
and raise pressure as described in the previous paragraph.
5. Make sure no gas is left in the measurement system during the calibration procedure.
Keep for example a valve connected to the measurement system open while priming
the system until all gas is removed or temporarily connect a vacuum pump to remove
gasfromthemeasurementsystem.Remembertoremove the vacuum pump fromthe
system before increasing the pressure.
Vent external systems before connecting to the pump.
6. Close PGHH’s vent valve fully clockwise.
7. Prime the system by squeezing handles together and then releasing, allowing the
fluid to enter the pump cylinder. Repeat as necessary until system is fully primed and
low pressure is indicated on either a calibrator or the test instrument.
10
Ensure that there is always a reliable pressure indicator connected to the pump when the pump is
used.
8. Test how much pressure increase can be done using the fine control. If it is enough,
continue to step 10.
9. With handles fully squeezed in, select the high pressure position on the stroke
selector and operate handles to generate approximate pressure. Smaller handle
strokes enable easier pressure generation at high pressures. The rate of the
pressure increase depends on the volume of the measurement system. Carefully
follow the reading of the pressure indicator in order to avoid exceeding the
maximum pressure of the measurement system.
10. Adjust pressure to required value using the fine control. Immediately after pressure
generation, the pressure may fall slightly due to the stretching 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 control.
11. The principal tool for releasing pressure from the measurement system is PGHH’s fine
control. Use of PGHH’s vent valve is also possible, but requires caution in order to
avoid pressure shocks to the measurement system.
12. To totally release pressure from the system, turn PGHH’s vent valve
counterclockwise. Return the stroke selector knob to prime position after first
squeezing handles fully in.
Never fully screw out the ent valve. The sealling ball, placed inside the pump, may wear off.
If there is a strong counterforce while operating the handles, but no pressure increase is indicated,
stop pumping and locate the fault. Always keep a reliable indicator connected to the measurement
system.
The measurement system must only contain the measurement liquid and no gas.
