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.
